CISA Certified Information Systems Auditor Questions and Answers

A vendor requires privileged access to a key business application. The best recommendation to reduce the risk of data leakage is to implement real-time activity monitoring for privileged roles. This is because real-time activity monitoring can provide visibility and accountability for the actions performed by the vendor with privileged access, such as creating, modifying, deleting, or copying data. Real-time activity monitoring can also enable timely detection and response to any unauthorized or suspicious activities that may indicate data leakage. Including the right-to-audit in the vendor contract is a good practice, but it may not be sufficient to prevent or detect data leakage in a timely manner, as audits are usually performed periodically or on-demand. Performing a review of privileged roles and responsibilities is also a good practice, but it may not address the specific risk of data leakage by the vendor with privileged access. Requiring the vendor to implement job rotation for privileged roles may reduce the risk of collusion or fraud, but it may not prevent or detect data leakage by any individual with privileged access. References: CISA Review Manual (Digital Version), [ISACA Privacy Principles and Program Management Guide]

When an IS auditor discovers a security weakness in the database configuration, the next course of action should be to identify existing mitigating controls. This involves assessing whether any controls are already in place to address the weakness and mitigate the risk. Understanding the current state of controls helps the auditor determine the severity of the issue and whether additional corrective actions are necessary1. References: 1(https://www.isaca.org/resources/insights-and-expertise/audit-programs-and-tools)

 The most important consideration for a go-live decision when implementing an upgraded enterprise resource planning (ERP) system is the business case. The business case is the document that defines and justifies the need, value, feasibility, and risks of the project. It also outlines the expected costs, benefits, outcomes, and impacts of the project. The business case provides the basis for measuring and evaluating the success of the project. Therefore, before deciding to go live with an upgraded ERP system, it is essential to review and validate the business case to ensure that it is still relevant, accurate, realistic, and achievable.

A rollback strategy, test cases, and post-implementation review objectives are not the most important considerations for a go-live decision when implementing an upgraded ERP system. These are important elements of project planning, execution, and evaluation, but they are not sufficient to determine whether the project is worth pursuing or delivering. These elements should be aligned with and derived from the business case.

 Fine tuning the intrusion detection system (IDS) is the best recommendation to reduce the number of false positive alerts that overwhelm the log management system, because it can help adjust the sensitivity and accuracy of the IDS rules and signatures to match the network environment and traffic patterns. Establishing criteria for reviewing alerts, recruiting more monitoring personnel, and reducing thefirewall rules are not effective solutions to address theroot cause of the false positive alerts, but rather ways to cope with the consequences. References: CISA Review Manual (Digital Version), Chapter 5, Section5.4.3

 An IS auditor is conducting a review of a data center. An observation that could indicate an access control issue is muddy footprints directly inside the emergency exit. Access control is a process that ensures that only authorized entities or individuals can access or use an information system or resource, and prevents unauthorized access or use. Access control can be implemented using various methods or mechanisms, such as physical, logical, administrative, etc. Muddy footprints directly inside the emergency exit could indicate an access control issue, as they could suggest that someone has entered the data center through the emergency exit without proper authorization or authentication, and potentially compromised the security or integrity of the data center. Security cameras deployed outside main entrance is not an observation that could indicate an access control issue, but rather a control that could enhance access control, as security cameras are devices that capture and record video footage of the surroundings, and can help monitor and deter unauthorized access or activity. Antistatic mats deployed at the computer room entrance is not an observation that could indicate an access control issue, but rather a control that could prevent static electricity damage, as antistatic mats are devices that dissipate or reduce static charges from people or objects, and can help protect electronic equipment from electrostatic discharge (ESD). Fencing around facility is two meters high is not an observation that could indicate an access control issue, but rather a control that could improve physical security, as fencing is a barrier that encloses or surrounds an area, and can help prevent unauthorized entry or intrusion. 

Compliance testing ensures that the organization ' s incident response processes align with established cybersecurity frameworks and policies. This methodology provides objective and reliable conclusions about the maturity of incident response capabilities.

Judgmental Sampling (Option A):Relies on subjective judgment and is less reliable.

Data Analytics Testing (Option B):Useful for identifying trends but may not assess process maturity comprehensively.

Variable Sampling (Option C):Appropriate for statistical analysis but less effective in process maturity assessments.

The best evidence to determine whether transactions have been executed by authorized employees is audit trails. Audit trails are secure records that catalog events or procedures to provide support documentation. They are used to authenticate security and operational actions, mitigate challenges, or provide proof of compliance and operational integrity2. Audit trails can track and trace the following information related to transactions:

Who initiated, approved, modified, or deleted a transaction

When a transaction occurred (date and time)

Where a transaction took place (location or device)

What type of transaction was performed (action or operation)

Why a transaction was executed (purpose or reason)

By analyzing audit trails, an IS auditor can verify whether transactions have been executed by authorized employees or not. Audit trails can also identify any unauthorized, fraudulent, or erroneous transactions that may have occurred. Audit trails can also help to resolve any disputes or discrepancies that may arise from transactions.

Conducting periodic testing and incorporating lessons learned is the best way to improve the effectiveness of an incident response team. This allows the team to practice their response procedures, identify any gaps or weaknesses in their response, and learn from their mistakes. It also helps to keep the team’s skills sharp and up-to-date. The lessons learned from these tests can then be used to improve the team’s procedures and performance12. While understanding information systems technology, disseminating incident response procedures, and publishing KPI metrics can contribute to the effectiveness of the team, they do not provide the same level of continuous improvement as periodic testing and learning from experience.

The IS auditor’s next step after determining that many terminated users’ accounts were not disabled is to perform a review of terminated users’ account activity. This means that the IS auditor should check whether any of the terminated users’ accounts were accessed or used after their termination date, which could indicate unauthorized or fraudulent activity. The IS auditor should also assess the impact and risk of such activity on the confidentiality, integrity, and availability of IT resources and data. The other options are not as appropriate as performing a review of terminated users’ account activity, as they do not provide sufficient evidence or assurance of the extent and effect of the problem. References: CISA Review Manual, 27th Edition, page 240

A certificate authority (CA) is critical in a public key cryptographic system for mitigating man-in-the-middle (MITM) attacks. It ensures that public keys are authentic by issuing digital certificates, which bind a public key to an entity. The CA’s role in verifying identities and providing trust anchors prevents attackers from spoofing keys.

Strong Encryption Algorithms (Option A):Encryption ensures confidentiality but does not address spoofing risks.

Kerberos Authentication (Option B):Useful for mutual authentication but not central to public key infrastructure (PKI).

Registration Authority (Option C):Supports the CA but does not directly prevent MITM attacks.

EVA is a project management technique that measures the performance of a project by comparing the actual work completed, the actual costs incurred, and the planned costs for the work scheduled. EVA can help determine if the project is on track, ahead of schedule, or behind schedule, and if the project is under budget, over budget, or on budget. EVA can also help forecast the final cost and schedule of the project based on the current performance.

The best answer is D. To document relationships between configuration items.

ISACA’s configuration management guidance identifies the value of a CMDB in maintaining information about configuration items and their relationships. That relationship view is what supports effective impact analysis, change management, incident response, and dependency understanding across the environment.

Option A is too narrow. Option B describes monitoring rather than configuration management. Option C may be one data element in some environments, but the defining value of a CMDB is not physical location tracking. The central purpose is documenting configuration items and how they relate to one another.

 Leveraging an IT governance framework is the best way to enable alignment of IT with business objectives, as it provides a set of principles, standards, processes, and practices that guide the effective delivery of IT services that support the organization’s strategy and goals. Benchmarking against peer organizations, developing key performance indicators (KPIs), and completing an IT risk assessment are useful activities that can help measure and improve the performance and value of IT, but they are not sufficient to ensure alignment without a governance framework. References: CISA Review Manual (Digital Version), Chapter 1: Information Systems Auditing Process, Section 1.2: IT Governance

The best approach for determining the overall IT risk appetite of an organization when business units use different methods for managing IT risks is to prioritize the organization’s IT risk scenarios. IT risk appetite is the amount and type of IT risk that an organization is willing to accept in pursuit of its objectives. IT risk scenarios are hypothetical situations that describe the potential impact of IT risk events on the organization’s objectives, processes, and resources. By prioritizing the organization’s IT risk scenarios, the IS auditor can identify the most significant IT risks that affect the organization as a whole, and align them with the organization’s strategic goals, values, and culture. Prioritizing the organization’s IT risk scenarios can also help to communicate and monitor the IT risk appetite across the organization, and facilitate consistent and informed decision making. The other approaches (A, B and D) are not effective for determining the overall IT risk appetite of an organization, as they do not consider the impact and likelihood of IT risks on the organization’s objectives, nor do they account for the diversity and complexity of IT risks across different business units. References: CISA Review Manual (Digital Version), Chapter 2: Governance and Management of Information Technology, Section 2.3: Information Technology Risk Management

The best answer is B. Senior management.

The culture that supports an effective internal control system is set from the top. ISACA’s governance and culture guidance consistently treats culture as a management and leadership responsibility. Senior leadership establishes tone, values, expectations, accountability, and behavioral norms that shape how controls are designed, followed, and enforced across the enterprise. A strong control culture depends on visible commitment from leadership, not just procedural ownership by operational teams.

Option A. HR supports the culture through hiring, training, and policy reinforcement, but HR does not have primary accountability for the overall control environment.

Option C. Line management plays an important role in day-to-day control execution, but enterprise culture is primarily driven by senior leadership.

Option D. Internal audit evaluates and provides assurance over the control system; it does not own or establish the control culture because doing so would impair independence.

Therefore, B is the correct answer because senior management is primarily accountable for establishing the tone and culture that enable an effective and efficient internal control system.

The most useful information regarding an organization’s risk appetite and tolerance is provided by its risk profile, as this is a document that summarizes the key risks that the organization faces, the potential impacts and likelihoods of those risks, and the acceptable levels of risk exposure for different objectives and activities. A gap analysis is a tool that compares the current state and the desired state of a process or a system, and identifies the gaps that need to be addressed. Audit reports are documents that present the findings, conclusions, and recommendations of an audit engagement. A risk register is a tool that records and tracks the identified risks, their causes, their consequences,and their mitigation actions. References: CISA Review Manual (Digital Version), Chapter 2: Governance and Management of IT, Section 2.1: IT Governance

 When auditing the closing stages of a system development project, the most important consideration should be the user acceptance test (UAT) results. The UAT is a critical phase of the system development life cycle (SDLC) that ensures that the system meets the functional requirements and expectations of the end users. The UAT results provide evidence of the system’s quality, performance, usability, and reliability. Control requirements, rollback procedures, and functional requirements documentation are also important considerations, but they are not ascrucial as the UAT results in determining if the system is ready for deployment. References: CISA Review Manual (Digital Version)1, page 325.

The most effective way for the audit team to leverage the risk management maturity of the organization is to integrate the risk register for audit planning purposes. The risk register is a document that records the identified risks, their likelihood, impact, and mitigation strategies for a project or an organization. By using the risk register, the audit team can align their audit objectives, scope, and procedures with the organization’s risk profile and priorities. This will help the audit team to provide more value-added and relevant assurance and recommendations to the management and stakeholders.

CISA CertifiedInformation Systems Auditor – Question0551

The IS auditor’s first course of action should be to verify the results of the critical automatic calculations made by the system to determine the validity of user concerns. This is because the IS auditor needs to obtain sufficient and appropriate audit evidence to support the audit findings and conclusions. By verifying the results, the IS auditor can assess whether there are any errors or discrepancies in the system’s calculations that could affect the accuracy and reliability of the financial data. The IS auditor can use various techniques to verify the results, such as re-performing the calculations, comparing them with expected values, or tracing them to source documents. 

The best way to detect unauthorized copies of licensed software on systems is to conduct periodic software scanning. Software scanning is a process of using specialized tools or programs to scan the systems and identify the software installed, the license status, the usage, and the compliance with the software policies and agreements. Software scanning can help to detect any unauthorized, unlicensed, or illegal copies of software on the systems, as well as any discrepancies or violations of the software licenses. Software scanning can also help to optimize the software inventory, reduce the software costs, and improve the security and performance of the systems12.

Some examples of software scanning tools are:

Microsoft Software Inventory Analyzer (MSIA): A free tool that scans Windows-based computers and servers and generates reports on the Microsoft products installed, such as operating systems, applications, and updates3.

Belarc Advisor: A free tool that scans Windows-based computers and generates reports onthe hardware and software installed, including license keys, versions, usage, and security status4.

Lansweeper: A paid tool that scans Windows, Linux, Mac, and other network devices and generates reports on the hardware and software inventory, license compliance, configuration, and vulnerabilities5.

To conduct periodic software scanning, you need to:

Choose a suitable software scanning tool that meets your needs and budget.

Define the scope and frequency of the software scanning, such as which systems to scan, how often to scan, and what information to collect.

Configure and run the software scanning tool according to the instructions and settings.

Review and analyze the software scanning reports and identify any unauthorized copies of licensed software on the systems.

Take appropriate actions to remove or regularize the unauthorized copies of licensed software on the systems.

Document and report the results and findings of the software scanning.

Regression testing is the most appropriate testing method for assessing whether system integrity has been maintained after changes have been made. Regression testing is a type of software testing that ensures that previously developed and tested software still performs as expected after a change1 Regression testing helps to detectany defects or errors that may have been introduced or uncovered due to the change2 Regression testing can be performed at different levels of testing, such as unit, integration, system, and acceptance3

Unit testing is a type of software testing that verifies the functionality of individual components or units of code. Unit testing is usually performed by developers before integrating the code with other components. Unit testing helps to identify and fix errors at an early stage of development, but it does not ensure that the system as a whole works as expected after a change.

Integration testing is a type of software testing that verifies the functionality, performance, and reliability of the interactions between different components or units of code. Integration testing is usually performed after unit testing and before system testing. Integration testing helps to identify and fix errors that may occur when different components are integrated, but it does not ensure that the system as a whole works as expected after a change.

Acceptance testing is a type of software testing that verifies whether the system meets the user requirements and expectations. Acceptance testing is usually performed by end-users or customersafter system testing and before deploying the system to production. Acceptance testing helps to ensure that the system delivers the desired value and quality to the users, but it does not ensure that the system as a whole works as expected after a change.

The best option for the question is C, information owner. This is because:

The information owner is the person or entity that has the authority and responsibility for the business processes and functions that collect, use, store, and dispose of data1.

The information owner is accountable for ensuring that the data is handled in compliance with the applicable laws, regulations, policies, and standards, such as the GDPR and the PIPEDA1234.

The information owner is in the best position to determine the purpose and necessity of collecting and retaining data, as well as the risks and benefits associated with it1.

The information owner should consult with other stakeholders, such as the risk manager, the database administrator (DBA), and the privacy manager, to establish and implement appropriate data classification policies and procedures2.

Data classification is the process of organizing data in groups based on their attributes and characteristics, and then assigning class labels that describe a set of attributes that hold true for the corresponding data sets345.

Data classification helps organizations to identify, manage, protect, and understand their data, as well as to comply with modern data privacy regulations345.

Data classification also helps to determine appropriate user access levels, which means defining who can access, modify, share, or delete data based on their roles, responsibilities, and needs345.

Therefore, the information owner should be responsible for the data classification in an ERP migration project from local systems to the cloud (option C), as they have the authority and accountability for the data and its protection.

The other options are not correct because:

The information security officer (option A) is responsible for overseeing and coordinating the security policies and practices of the organization that involve data6. The information security officer should advise and assist the information owner on the best practices and standards for data security, but not determine the data classification.

The database administrator (DBA) (option B) is responsible for installing, configuring, monitoring, maintaining, and improving the performance of databases and data stores that contain data5. The DBA should support the information owner in implementing and enforcing the data classification policies and procedures, but not determine them.

The data architect (option D) is responsible for designing, modeling, and documenting the logical and physical structures of databases and data stores that contain data7. The data architect should collaborate with the information owner in creating and maintaining the data classification schema and metadata, but not determine them.

The best recommendation for the auditor to make is D. Line management should regularly review and request modification of access rights. Access rights are the permissions and privileges granted to users to access, view, modify, or delete data or resources on a system or network1. Excessive rights are access rights that are not necessary or appropriate for a user’s role or function, and may pose a risk of unauthorized or inappropriate use of data or resources2. Therefore, it is important to ensure that access rights are alignedwith the principle of least privilege, which means that users should only have the minimum level of access required to perform their duties2.

Line management is responsible for overseeing and supervising the activities and performance of their staff, and ensuring that they comply with the organization’s policies and standards3. Therefore, line management should regularly review and request modification of access rights for their staff, as they are in the best position to:

Understand the roles and functions of their staff, and determine the appropriate level of access rights needed for them to perform their duties effectively and efficiently.

Monitor and evaluate the usage and behavior of their staff, and identify any changes or anomalies that may indicate excessive or inappropriate access rights.

Communicate and collaborate with IT security or system administrators, who are responsible for granting, revoking, or modifying access rights, and request any necessary adjustments or corrections.

A digital signature is the most appropriate control to ensure integrity of online orders because it provides a way to verify the authenticity and integrity of the data sent by the sender. A digital signature is created by applying a cryptographic algorithm to the data and attaching the result to the data. The receiver can then use the sender’s public key to verify that the data has not been altered or tampered with during transmission. A digital signature also provides non-repudiation, which means that the sender cannot deny sending the data.

Data Encryption Standard (DES) is a symmetric encryption algorithm that can provide confidentiality of online orders, but not integrity. DES uses the same key to encrypt and decrypt the data, which means that anyone who has the key can modify the data without detection.

Public key encryption is an asymmetric encryption algorithm that can also provide confidentiality of online orders, but not integrity. Public key encryption uses a pair of keys: a public key and a private key. The sender encrypts the data with the receiver’s public key, and the receiver decrypts it with their own private key. However, public key encryption does not prevent anyone from modifying the encrypted data.

Multi-factor authentication is a control that can provide authentication and authorization of online orders, but not integrity. Multi-factor authentication requires the user to provide two or more pieces of evidence to prove their identity, such as a password, a token, or a biometric factor. Multi-factor authentication can prevent unauthorized access to online orders, but it does not protect the data from being modified after being sent.

 The most important thing for an IS auditor to confirm when reviewing an organization’s plans to implement robotic process automation (RPA) to automate routine business tasks is that the end-to-end process is understood and documented. This is because RPA involves the use of software robots or digital workers to mimic human actions and execute predefined rules and workflows. Therefore, it is essential that the IS auditor verifies that the organization has a clear and accurate understanding of the current state of the process, the desired state of the process, the inputs and outputs, the exceptions and errors, the roles and responsibilities, and the performance measures12. Without a properdocumentation of the end-to-end process, the organizationmay face challenges in designing, developing, testing, deploying, and monitoring the RPA solution3. References: 1: CISA ReviewManual (Digital Version), Chapter 4: Information Systems Operations and Business Resilience, Section 4.2: IT Service Delivery and Support, page 211 2:CISA Online Review Course, Module 4: Information Systems Operations and Business Resilience, Lesson 4.2: IT Service Delivery and Support 3: ISACA Journal Volume 5, 2019, Article: Robotic Process Automation: Benefits, Risks and Controls

 Scope creep is the uncontrolled expansion of a project’s scope, which can result in delays, cost overruns, and quality issues. To mitigate the risk of scope creep, an IS auditor should look for projectchange management controls, which are processes and procedures for managing changes to the project’s scope, schedule, budget, and quality. Project change management controls ensure that changes are properly requested, approved, documented, communicated, and implemented. Source code version control, existence of an architecture review board, and configuration management are also important for software development, but they do not directly address the risk of scope creep. References: ISACA Frameworks: Blueprints for Success, Project Management Institute: A Guide to the Project Management Body of Knowledge

 Information security governance is the subset of enterprise governance that provides strategic direction, ensures that objectives are achieved, manages risk appropriately, uses organizational resources responsibly, and monitors the success or failure of the enterprise security program. Information security governance is essential for ensuring that an organization’s information assets are protected from internal and external threats, and that the organization complies with relevant laws and standards.

Demonstrated support from which of the following roles in an organization has the most influence over information security governance? The answer is C, the board of directors. The board of directors is the highest governing body of an organization, responsible for overseeing its strategic direction, performance, and accountability. The board of directors sets the tone at the top for information security governance by:

Establishing a clear vision, mission, and values for information security

Approving and reviewing information security policies and standards

Allocating sufficient resources and budget for information security

Appointing and empowering a chief information security officer (CISO) or equivalent role

Holding management accountable for information security performance and compliance

Communicating and promoting information security awareness and culture

The board of directors has the most influence over information security governance because it has the ultimate authority and responsibility for ensuring that information security is aligned with the organization’s business objectives, risks, and stakeholder expectations.

The IS auditor’s best course of action when preparing the final report is to include the position supported by senior management in the final engagement report. The IS auditor should communicate the audit findings and recommendations to senior management and obtain their feedback and approval before issuing the final report. If there is a disagreement between the auditee and the IS auditor regarding a recommendation for corrective action, the IS auditor should present both sides of the argument and the supporting evidence, and seek senior management’s opinion and decision. The IS auditor should respect and follow senior management’s position, and include it in the final engagement report, along with the auditee’s comments if applicable. The other options arenot the best course of action, because they either do not resolve the disagreement, do notreflect senior management’s authority, or do not report the audit results accurately and completely. References: CISA Review Manual (Digital Version)1, Chapter 2, Section 2.2.5

A project business case is a document that describes the rationale and justification for initiating a project, based on its expected costs, benefits, risks, and feasibility. A project business case provides the most useful information to an IS auditor when selecting projects for inclusion in an IT audit plan, because it helps the IS auditor to:

Understand the purpose, scope, objectives, and deliverables of the project

Assess the alignment of the project with the organization’s strategy, vision, and goals

Evaluate the value proposition and return on investment of the project

Identify the key stakeholders, sponsors, and owners of the project

Analyze the potential risks and issues associated with the project

Compare and prioritize the project with other competing projects

The other possible options are:

A. Project charter: A project charter is a document that formally authorizes and defines the high-level scope, roles, responsibilities, and authority of a project. A project charter provides some useful information to an IS auditor when selecting projects for inclusion in an IT audit plan, but it is not the most useful information. A project charter does not provide enough details about the costs, benefits, risks, and feasibility of the project, which are essential for evaluating its suitability for an IT audit plan.

B. Project plan: A project plan is a document that outlines the detailed scope, schedule, budget, resources, quality, and communication plans of a project. A project plan provides some useful information to an IS auditor when selecting projects for inclusion in an IT audit plan, but it is not the most useful information. A project plan does not provide enough information about the rationale, justification, value proposition, and alignment of the project with the organization’s strategy and goals, which are important for assessing its relevance for an IT audit plan.

C. Project issue log: A project issue log is a document that records and tracks the issues that arise during a project’s execution and how they are resolved. A project issue log provides some useful information to an IS auditor when selecting projects for inclusion in an IT audit plan, but it is not the most useful information. A project issue log does not provide enough information about the purpose, objectives, benefits, and feasibility of the project, which are critical for determining its priority for an IT audit plan.

The primary purpose of a Business Impact Analysis (BIA) is to prioritize the restoration of systems and applications (D) based on their criticality to business operations. A BIA assesses the impact of disruptions, identifies critical processes, and determines recovery time objectives (RTOs) and recovery point objectives (RPOs).

Other options:

Identifying legal obligations (A) is an aspect of compliance but not the primary benefit of a BIA.

Providing updates on disaster risk levels (B) falls under risk management rather than BIA objectives.

Delineating employee responsibilities (C) is part of business continuity planning (BCP), not the BIA’s main goal.

The most effective method for positive authentication for physical access is a retina scan because it uses a biometric characteristic that is strongly tied to the individual and difficult to share, transfer, or replicate compared with cards, codes, or visual checks. ISACA materials discussing physical access and identity verification recognize biometrics such as retina scans as a high-assurance authentication mechanism.

Option B is correct because positive authentication means reliably confirming that the person presenting for access is truly the claimed individual. A retina scan verifies “something you are,” which is generally stronger than “something you have” or “something you know” for physical access authentication.

Option A is weaker because a proximity card is only possession-based authentication. It can be lost, borrowed, stolen, or shared, so it does not positively verify identity to the same degree as biometrics. This makes it less effective than a retina scan.

Option C is also weaker. A numeric keypad depends on a code that can be disclosed or observed, and a surveillance camera is more detective than authentication-focused. Together they do not provide the same strong identity binding as biometrics.

Option D improves assurance somewhat, but a smart card is still possession-based and a security guard’s judgment can be fallible. Human verification helps, but it does not usually match the direct individual-specific certainty of biometric authentication.

Therefore, B is the best answer because a retina scan most effectively provides positive authentication by directly verifying an individual’s unique biometric characteristic.

Maximum Tolerable Outage (MTO) (A) defines the longest time an organization can tolerate an IT service being unavailable before significant business impact occurs. It determines business continuity planning and disaster recovery strategies.

Other options:

RPO (B) defines acceptable data loss but does not determine the total outage limit.

SDO (C) is related to service agreements but does not set the risk threshold.

AIW (D) is similar to MTO but is not as commonly used in disaster recovery planning.

The best course of action for an IS auditor who finds that some critical recommendations have not been implemented is to evaluate senior management’s acceptance of the risk. The IS auditor should understand the reasons why the recommendations have not been implemented and the implications for the organization’s risk exposure. The IS auditor should also verify that senior management has formally acknowledged and accepted the residual risk and has documented the rationale and justification for their decision. The IS auditor should communicate the findings and the risk acceptance to the audit committee and other relevant stakeholders. References:

CISA Review Manual (Digital Version)

CISA Questions, Answers and Explanations Database

 The auditor’s next course of action should be to evaluate the appropriateness of the remedial action taken by the auditee. The auditor should assess whether the alternative approach taken by the auditee is effective, efficient, and aligned with the audit objectives and recommendations. The auditor should also consider the impact of the change on the audit scope, criteria, and risk assessment. Conducting a risk analysis incorporating the change, reporting results of the follow-up to the audit committee, and informing senior management of the change in approach are possible subsequent actions that the auditor may take after evaluating the appropriateness of the remedial action taken. References: CISA Review Manual (Digital Version): Chapter 1 - Information Systems Auditing Process

Enterprise Architecture (EA) governance requires proper oversight and separation of duties to ensure strategic alignment and risk management.

Option A (Correct):If IT application owners have sole authority over architecture approval, there is a high risk of inadequate governance, lack of strategic alignment, and potential conflicts of interest. Architecture decisions should involve multiple stakeholders, including business and security teams, to ensure compliance, security, and business alignment.

Option B (Incorrect):While having the CIO chair the architecture review board might not be ideal, it is not thegreatestconcern. The CIO is a senior leader who can provide oversight and direction, even if additional governance mechanisms should be in place.

Option C (Incorrect):Reviewing security requirements within the EA program is abest practice, as it ensures that security is embedded into enterprise architecture rather than treated as an afterthought.

Option D (Incorrect):Enterprise architecture should ideally encompass both IT and business processes. Governing non-IT-related projects is not inherently problematic, as EA is designed to align business strategy with IT infrastructure.

The best source of information for an IS auditor to use as a baseline to assess the adequacy of an organization’s privacy policy is the local privacy standards and regulations. Privacy standards and regulations are legal requirements that specify how personal data should be collected, processed, stored, shared, and disposed of by organizations. By using local privacy standards and regulations as a baseline, the IS auditor can ensure that the organization’s privacy policy complies with the applicable laws and protects the rights and interests of data subjects. Historical privacy breaches and related root causes, globally accepted privacy best practices, and benchmark studies of similar organizations are useful sources of information for improving an organization’s privacy policy, but they are not as authoritative and relevant as local privacy standards and regulations. References: CISAReview Manual (Digital Version): Chapter 2 - Governance and Management of Information Technology

Internalquality assurance (QA) reviewsare conducted toensure conformancewith professionalaudit standards and methodology.

Option A (Correct):The primary purpose of QA reviews is toconfirm that the internal audit function adheres to industry standards, such asISACA’s IT audit frameworkand theInternational Standards for the Professional Practice of Internal Auditing (IPPF).

Option B (Incorrect):Whilegovernance and performance metricsare important,conformance to standardsis theprimary goalof QA reviews.

Option C (Incorrect):Risk management is part of audits, butQA reviews focus on adherence to methodologyrather than reducing audit risk.

Option D (Incorrect):Efficient resource usageis a goal butnot the main objectiveof an audit QA program.

Prior to a follow-up engagement, if an IS auditor learns that management has decided to accept a level of residual risk related to an audit finding without remediation, the IS auditor should report the issue to IS audit management. This is because IS audit management is responsible for ensuring that audit findings are properly communicated and resolved. Accepting management’s decision and continuing the follow-up would not address the IS auditor’s concern. Reporting the disagreement to the board or executive management would be premature and inappropriate without consulting IS audit management first. References: CISA Review Manual (Digital Version), Chapter 1, Section 1.6

Implementing business rules to validate employee data entry is the best way to reduce the likelihood of future occurrences of poor data quality that cause customer complaints about receiving different items from what they ordered on the organization’s website. Business rules are logical statements that define the conditions and actions for data validation, such as checking for data completeness, accuracy, consistency, and integrity. Assigning responsibility for improving data quality, investing in additional employee training for data entry, and outsourcing data cleansing activities to reliable third parties are also possible ways to improve data quality, but they are not as effective as implementing business rules to validate employee data entry. References: CISA Review Manual (Digital Version), Chapter 4, Section 4.3.1

Issuing authentication tokens is the most reliable method of preventing unauthorized logon, as it provides a strong form of authentication that requires users to present something they have (the token) and something they know (the personal identification number or PIN) to access the system. Authentication tokens are physical devices that generate a one-time password or code that changes periodically and is synchronized with the authentication server. This makes it difficult for attackers to steal or guess the credentials of legitimate users. Reinforcing current security policies, limiting after-hours usage and installing an automatic password generator are not as reliable as issuing authentication tokens, as they do not provide a strong form of authentication and may still be vulnerable to unauthorized logon attempts. References:

The most significant risk when an application uses individual end-user accounts to access the underlying database is that users may be able to circumvent application controls. Application controls are the policies, procedures, and mechanisms that ensure the accuracy, completeness, validity, and authorization of transactions and data within an application. Application controls can include input validation, output verification, processing logic, reconciliation, exception handling, and audit trails. Application controls can help prevent or detect errors, fraud, or unauthorized access or modification of data.

However, if an application uses individual end-user accounts to access the underlying database, it means that the users have direct access to the database without going through the application layer. This can expose the database to potential risks such as:

Users may be able to bypass the application controls and manipulate the data in the database directly using SQL commands or other tools. For example, users may be able to change their own or others’ salaries, grades, or balances without proper authorization or validation.

Users may be able to access or disclose sensitive or confidential data that they are not supposed to see or share. For example, users may be able to view other users’ personal information, passwords, or credit card numbers.

Users may be able to introduce errors or inconsistencies in the data by entering invalid or incorrect data or by deleting or modifying existing data. For example, users may be able to create duplicate records, break referential integrity, or cause data loss or corruption.

Users may be able to compromise the security and performance of the database by creating unauthorized objects, granting excessive privileges, executing malicious code, or consuming excessive resources. For example, users may be able to create backdoors, viruses, or denial-of-service attacks.

Therefore, using individual end-user accounts to access the underlying database can pose a serious threat to the integrity, confidentiality, availability, and reliability of the data and the application.

The other options are not as significant as option C. Multiple connects to the database are used and slow the process is a performance issue that can affect the efficiency and responsiveness of the application and the database, but it does not necessarily compromise the data quality or security. User accounts may remain active after a termination is a security issue that can increase the risk of unauthorized access or misuse of data by former employees or others who have access to their credentials, but it can be mitigated by implementing proper account management and monitoring processes. Application may not capture a complete audit trail is a compliance issue that can affect the accountability and traceability of transactions and data within the application and the database, but it does not directly affect the data accuracy or protection.

Normalizationis the process ofstructuring log datainto a standard format for easy analysis and correlation across multiple systems.

Normalization (Correct Answer – D)

Ensures consistency in log file formats.

Helps security analysts detect patterns and anomalies.

Example:Converting log timestamps into a standardized format (UTC).

Extraction (Incorrect – A)

Retrieves data but does not format it for analysis.

Data Acquisition (Incorrect – B)

Refers to collecting data, not structuring it.

Imaging (Incorrect – C)

Creates copies of disk storage but is unrelated to log analysis.

Admin accounts typically have the highest level of privileges and access to sensitive data. If the passwords for these accounts are not set to expire, it increases the risk of unauthorized access and potential security breaches. This is especially true if an admin’s credentials are compromised, as the attacker could have ongoing access to critical systems and data1.

The most important factor to ensure when developing an effective security awareness program is B. Outcome metrics for the program are established. This is because outcome metrics are measures that evaluate the impact and results of the security awareness program on the behavior and performance of the users, and the security posture and objectives of the organization1. Outcome metrics can help ensure the effectiveness of the security awareness program by:

Providing feedback and evidence on whether the security awareness program is achieving its goals and expectations, such as reducing the number of incidents, improving the compliance rate, or increasing the reporting rate1.

Identifying and quantifying the strengths and weaknesses of the security awareness program, and enabling continuous improvement and optimization of the program content, delivery, and frequency1.

Demonstrating and communicating the value and return on investment of the security awareness program to the stakeholders and management, and securing their support and commitment for the program1.

 The most important thing for an IS auditor to look for in a project feasibility study is an assessment of whether the expected benefits can be achieved. A project feasibility study is a preliminary analysis that evaluates the viability and suitability of a proposed project based on various criteria, such as technical, economic, legal, operational, and social factors. The expected benefits are the positive outcomes and value that the project aims to deliver to the organization and its stakeholders. The IS auditor should verify whether the project feasibility study has clearly defined and quantified the expected benefits, and whether it has assessed the likelihood and feasibility of achieving them within the project scope, budget, schedule, and quality parameters. The other options are also important for an IS auditor to look for in a project feasibility study, but not as important as an assessment of whether the expected benefits can be achieved, because they either focus on specific aspects of the project rather than the overall value proposition, or they assume that the project will be implemented rather than evaluating its viability. References: CISA Review Manual (Digital Version)1, Chapter 4, Section 4.2.1

Comprehensive and Detailed in-Depth Explanation:

Implementing edit checks ensures data validity and integrity by verifying inputs and reducing inconsistencies in the database.

Updating the data dictionary (Option A) does not resolve inconsistency issues. Data modeling (Option C) and training (Option D) are less relevant to addressing data accuracy directly.

 A computer forensic audit is a process of collecting, preserving, analyzing, and presenting digital evidence from electronic devices in a legally admissible manner. It is most relevant in situations where data loss due to hacking of servers occurs, as it can help to identify the source, method, and extent of the attack, as well as recover the lost or damaged data. The other options are not as suitable for a computer forensic audit, as they relate to internal control issues, data quality issues, orsystem maintenance issues, which can be addressed by other types of audits or reviews. References: CISA Review Manual (Digital Version), Domain 4: Information Systems Operations and Business Resilience, Section 4.5 Computer Forensics1

 A configuration management system is a process that establishes and maintains the consistency of a product’s attributes throughout its life cycle. It helps to identify and control the functional and physical characteristics of a product, and to record and report any changes to those characteristics. A configuration management system also supports the audit of the product to verify its conformance to requirements.

One of the key activities of a configuration management system is to define baselines for software. A baseline is a fixed reference point that serves as a basis for comparison and measurement. A baseline can be established for any configuration item, such as a requirement, a design document, a test plan, or a software component. A baseline helps to ensure that the software product meets its intended purpose and quality standards, and that any changes to the software are controlled and documented.

A configuration management system also supports other activities, such as tracking software updates, supporting the release procedure, and standardizing change approval, but these are not its primary purpose. Therefore, the other options are incorrect.

The greatest risk associated with having most users with administrator access to an externally facing system containing sensitive data is that users can make unauthorized changes to the system or the data, which could compromise the integrity, confidentiality, and availability of the system and the data. Users can export application logs, view sensitive data, and install open-licensed software are also risks, but they are not as severe as unauthorized changes. References: ISACA CISA Review Manual 27th Edition Chapter 4

 Substantive testing provides the most reliable audit evidence on the validity of transactions in a financial application. Substantive testing is an audit procedure that examines the financial statements and supporting documentation to see if they contain errors or misstatements. Substantive testing can help to verify that the transactions recorded in the financial applicationare authorized, complete, accurate, and properly classified. Substantive testing can include methods such as vouching, confirmation, analytical procedures, or physical examination. 

The best document for an IS auditor to use in detecting a weakness in segregation of duties is a process flowchart. A process flowchart is a diagram that illustrates the sequence of steps, activities, tasks, or decisions involved in a business process. A process flowchart can help detect a weakness in segregation of duties by showing who performs what actions or roles in a process, and whether there is any overlap or conflict of interest among them. The other options are not as useful as a process flowchart in detecting a weakness in segregation of duties, as they do not show who performs what actions or roles in a process. A system flowchart is a diagram that illustrates the components, functions, interactions, or logic of an information system. A data flow diagram is a diagram that illustrates how data flows from sources to destinations through processes, stores, or external entities. An entity-relationship diagram is a diagram that illustrates how entities (such as tables) are related to each other through attributes (such as keys) in a database. References: CISA ReviewManual (Digital Version), Chapter 3, Section 3.2

The greatest risk associated with storing customer data on a web server is data confidentiality. Data confidentiality is the property that ensures that data are accessible only to authorized entities or individuals, and protected from unauthorized disclosure or exposure. Storing customer data on a web server poses a high risk to data confidentiality, as web servers are exposed to the internet and may be vulnerable to various types of attacks or breaches that can compromise the security and privacy of customer data, such as hacking, phishing, malware, denial of service (DoS), etc. Customer data may contain sensitive or personal information that can cause harm or damage to customers or the organization if disclosed or exposed, such as identity theft, fraud, reputation loss, legal liability, etc. Data availability is the property that ensures that data are accessible and usable by authorized entities or individuals when needed. Data availability is a risk associated with storing customer data on a web server, as web servers may experience failures or disruptions that can affect the accessibility and usability of customer data, such as hardware faults, network issues, power outages, etc. However, data availability is not the greatest risk associated with storing customer data on a web server, as it does not affect the security and privacy of customer data. Data integrity is the property that ensures that data are accurate and consistent, and protected from unauthorized modification or corruption. Data integrity is a risk associated with storing customer data on a web server, as web servers may be subject to attacks or errors that can affect the accuracy and consistency of customer data, such as injection attacks, tampering, replication issues, etc. However, data integrity is not the greatest risk associated with storing customer data on a web server, as it does not affect the security and privacy of customer data. Data redundancy is the condition of having duplicate or unnecessary data in a database or system. Data redundancy is not a risk associated with storing customer data on a web server, but rather a result of poor database design or management. 

 Clustering is a technique that allows multiple servers to work together as a single system, providing high availability, load balancing, and fault tolerance. Clustering can limit the potential impact of server failures in a distributed environment, as it can automatically switch the workload to another server in the cluster if one server fails, without interrupting the service. Redundant pathways, failoverpower, and parallel testing are also useful for improving the reliability and availability of servers, but they do not directly address the issue of server failures. 

Threat modeling is an approach that enables IS auditors to identify, analyze, and mitigate potential security vulnerabilities within an application by understanding the threats, attacks, vulnerabilities, and countermeasures. This proactive technique helps in designing secure applications.

The most important thing to determine during the planning phase of a cloud-based messaging and collaboration platform acquisition is the types of data that can be uploaded to the platform. This is because different types of data may have different security, privacy, and compliance requirements, depending on the nature, sensitivity, and value of the data. For example, personal data, financial data, health data, or intellectual property data may be subject to various laws and regulations thatgovern how they can be collected, stored, processed, and shared in the cloud. Therefore, it is essential to identify and classify the types of data that will be uploadedto the platform, and ensure that the platform meets the organization’s policies and standards for data protection1.

The other options are not as important as the types of data that can be uploaded to the platform during the planning phase of a cloud-based messaging and collaboration platform acquisition. Option A, role-based access control policies, is a mechanism that defines who can access what data and resources on the platform based on their roles and responsibilities. Role-based access control policies are important for ensuring data security and accountability, but they can be designed and implemented after the platform is acquired2. Option C, processes for on-boarding and off-boarding users to the platform, are procedures that enable or disable user accounts and access rights on the platform. Processes for on-boarding and off-boarding users are important for managing user identities and lifecycles, but they can be developed and executed after the platform is acquired3. Option D, processes for reviewing administrator activity, are methods that monitor and audit the actions and events performed by administrators on the platform. Processes for reviewing administrator activity are important for detecting and preventing unauthorized or malicious activities, but they can be established and performed after the platform is acquired4.

 Digital watermarks are hidden marks or codes that can be embedded into digital files, such as images, videos, audio, or documents. They can be used to identify the source, owner, or authorized user of the data, as well as to track any unauthorized copying or distribution of the data. Digital watermarks can help prevent data leakage by deterring potential leakers from sharing sensitive data or by providing evidence of data leakage if it occurs.

The other options are not as effective as digital watermarks in preventing data leakage. Ensuring that paper documents are disposed securely can reduce the risk of physical data leakage, but it does not address the digital data leakage that is more prevalent in today’s environment. Implementing an intrusion detection system (IDS) can help detect and respond to cyberattacks that may cause data leakage, but it does not prevent data leakage from insiders or authorized users who have legitimate access to the data. Verifying that application logs capture any changes made can help audit and investigate data leakage incidents, but it does not prevent them from happening in the first place.

 The most important thing to assess when conducting a business impact analysis (BIA) is the completeness of critical asset inventory. This is because the critical asset inventory is the basis for identifying and prioritizing the business processes, functions, and resources that are essential for thecontinuity of operations. The critical asset inventory should include both tangible and intangible assets, such as hardware, software, data, personnel, facilities, contracts, and reputation. The critical asset inventory should also be updated regularly to reflect any changes in the business environment or needs. References:

The best evidence that an organization’s IT strategy is aligned to its business objectives is that the IT strategy is approved by executive management. This implies that the IT strategy has been reviewed and validated by the senior leaders of the organization, who are responsible for setting and overseeing the business objectives. The IT strategy may be modified inresponse to organizational change, based on IT operational best practices, or have significant impact on the business strategy, but these are not sufficient indicators of alignment without executive approval. References: CISA Review Manual (Digital Version)1, Chapter 1, Section 1.2.1

Information systems governance is the set of policies, processes, structures, and practices that ensure the alignment of IT with business objectives, the delivery of value from IT investments, the management of IT risks, and the optimization of IT resources1. Information systems governance is a strategic and high-level function that covers the entire organization and its IT portfolio. Therefore, an IS auditor should review the aspects of information systems governance that are relevant to the organization’s vision, mission, goals, and strategies.

One of the aspects that an IS auditor should review when evaluating information systems governance for a large organization is the approval processes for new system implementations. This is because new system implementations are significant IT investments that require careful planning, analysis, design,development, testing, deployment, and evaluation to ensure that they meet the business requirements, deliver the expected benefits, comply with the relevant standards and regulations, and minimize the potential risks2. The approval processes fornew system implementations should involve the appropriate stakeholders, such as senior management, business owners, IT managers,project managers, users, and auditors, who have the authority and responsibility to approve or reject the proposed system implementations based on predefined criteria and metrics3. The approval processes for new system implementations should also be documented, transparent, consisten t, and timely to ensure accountability and traceability4. Therefore, an IS auditor should review the approval processes for new system implementations to assess whether they are aligned with the information systems governance framework and objectives.

The other possible options are:

Procedures for adding a new user to the invoice processing system: This is an operational task that involves granting access rights and permissions to a specific user for a specific system based on the principle of least privilege. This is not a strategic or high-level function that falls under information systems governance. Therefore, an IS auditor should not review this aspect when evaluating information systems governance for a large organization.

Approval processes for updating the corporate website: This is a tactical task that involves making changes or enhancements to the content or design of the corporate website based on the business needs and feedback. This is not a strategic or high-level function that falls under information systems governance. Therefore, an IS auditor should not review this aspect when evaluating information systems governance for a large organization.

Procedures for regression testing system changes: This is a technical task that involves verifying that existing system functionalities are not adversely affected by new system changes or updates. This is not a strategic or high-level function that falls under information systems governance. Therefore, an IS auditor should not review this aspect when evaluating information systems governance for a large organization. References: 1: What is IT Governance? - Definition from Techopedia 2: System Implementation - an overview | ScienceDirect Topics 3: Project Approval Process - Project Management Knowledge 4: 5 Best Practices For A Successful Project Approval Process | Kissflow Project : Principle of Least Privilege (POLP) | Imperva : How to Update Your Website Content - 7 Step Guide | HostGator Blog : What Is Regression Testing?

 Impact assessment is an activity that occurs during the issues management process for a system development project. Issues management is a process of identifying, analyzing, resolving, and monitoring issues that may affect the project scope, schedule, budget, or quality. Impact assessment is a technique of evaluating the severity and priority of an issue, as well as its implications for the project objectives and deliverables. The other options are not activities that occur during the issues management process, but rather related to other processes such as contingency planning, configuration management, or help desk management. References:

The IS auditor’s best course of action if they suspect an organization’s computer may have been used to commit a crime is to contact the incident response team to conduct an investigation. The incident response team is a group of experts who are responsible for responding to security incidents, such as data breaches, ransomware attacks, or cybercrimes. The incident response team can help to preserve and collect digital evidence, determine the scope and impact of the incident, contain and eradicate the threat, and restore normal operations. The IS auditor should not examine the computer themselves, as they may inadvertently alter or destroy potential evidence, or compromise the chain of custody. The IS auditor should also not notify local law enforcement before further investigation, as this may escalate the situation unnecessarily or interfere with the internal investigation process. The IS auditor should advise management of the crime after the investigation, or as soon as possible if there is an imminent risk or legal obligation to do so.

This is because the follow-up of agreed corrective actions for reported audit issues should be done after the auditee has had enough time to implement the corrective actions and demonstrate their effectiveness and sustainability. The follow-up audit should not be too soon or too late, but based on a reasonable and realistic timeframe that allows for adequate testing and verification of the control operation12.

Answer A. Progress updates indicate that the implementation of agreed actions is on track. is not the best answer, because progress updates are not sufficient to guide the follow-up audit timing. Progress updates are useful for monitoring and communicating the status and challenges of the corrective actions, but they do not provide conclusive evidence of the control operation. The follow-up audit should be based on actual results and outcomes, not on expectations or projections12.

Answer C. Business management has completed the implementation of agreed actions on schedule. is not the best answer, because the completion of the implementation of agreed actions is not enough to guide the follow-up audit timing. The completion of the implementation only indicates that the auditee has taken the necessary steps to address the audit issues, but it does not guarantee that the corrective actions are effective and sustainable. The follow-up audit should be based on the evaluation and validation of the control operation, not on the completion of the control implementation12.

Answer D. Regulators have announced a timeline for an inspection visit. is not the best answer, because the regulators’ inspection visit is not relevant to guide the follow-up audit timing. The regulators’ inspection visit is an external factor that may or may not coincide with the internal follow-up audit schedule. The follow-up audit should be based on the internal audit plan and objectives, not on the external audit requirements or expectations12.

 Identifying business processes associated with personal data exchange with the affected jurisdiction is the most helpful activity in making an assessment of the organization’s level of exposure in the affected country. An IS auditor should understand how the organization’s business operations and functions rely on or involve the cross-border transfer of personal data, as well as the potentialimpacts and risks of the new regulation on the business continuity and compliance. The other options are less helpful activities that may provide additional information or context for the assessment, but not its primary focus. References:

The audit finding that should be of greatest concern is that tasks defined on the critical path do not have resources allocated, as this means that the project is likely to face significant delays and cost overruns, since the critical path is the sequence of activities that determines the minimum time required to complete the project. The actual start times of some activities being later than originally scheduled may indicate some minor deviations from the project plan, but they may not necessarily affect the overall project completion time if they are not on the critical path. The project manager lacking formal certification may affect the quality and efficiency of the project management process, but it does not necessarily imply that the project manager is incompetent or unqualified. Milestones have been defined for all project products, but they may not be realistic or achievable if they do not take into account the resource constraints and dependencies of the critical path tasks. References: CISA Review Manual (Digital Version), Chapter 2: Governance and Management of IT, Section 2.3: IT Project Management

 The greatest concern for an IS auditor if there are flaws in the mapping of accounts between a front-end subledger and a main ledger is the inaccuracy of financial reporting. A subledger is a detailed record of transactions for a specific account, such as accounts receivable, accounts payable, inventory, or fixed assets. A main ledger is a summary record of all transactions for all accounts in an accounting system. The mapping of accounts between a subledger and a main ledger is the process of linking or reconciling the transactions in the subledger with the corresponding entries in the main ledger. If there are flaws in the mapping of accounts, such as missing, duplicated, or incorrect transactions, the main ledger may not reflect the true financial position and performance of the organization. This may lead to inaccurate financial reporting, which may affect decision making, compliance, auditing, taxation, and stakeholder confidence.

Double-posting of a single journal entry, inability to support new business transactions, and unauthorized alteration of account attributes are not the greatest concerns for an IS auditor if there are flaws in the mapping of accounts between a front-end subledger and a main ledger. These are possible consequences or causes of flaws in the mapping of accounts, but they do not have as significant an impact as inaccuracy of financial reporting. Double-posting of a single journal entry may result in errors or discrepancies in the main ledger balances. Inability to support new business transactions may indicate limitations or inefficiencies in the accounting system design or configuration. Unauthorized alteration of account attributes may suggest weaknesses or breaches in access control or segregation of duties.

The primary benefit of automating application testing is to provide test consistency. Automated testing can ensure that the same test cases are executed in the same manner and order every time, which can improve the reliability and accuracy of the test results. Providing more flexibility, replacing all manual test processes, and reducing the time to review code are possible benefits of automating application testing, but they are not the primary benefit. References:

 The primary purpose of obtaining a baseline image during an operating system audit is to identify atypical running processes. A baseline image is a snapshot of the normal state and configuration of an operating system, including the processes that are expected to run on it. By comparing the current state of the operating system with the baseline image, an IS auditor can detect any deviations or anomalies that may indicate unauthorized or malicious activity, such as malware infection, privilege escalation, or data exfiltration. A baseline image can also help an IS auditor to assess the performance and efficiency of the operating system, as well as its compliance with security standards and policies.

Verifying antivirus definitions (option B) is not the primary purpose of obtaining a baseline image, although it may be a part of the baseline configuration. Antivirus definitions are the files that contain the signatures and rules for detecting and removing malware. An IS auditor may verify that the antivirus definitions are up to date and consistent across the operating system, but this does not require obtaining a baseline image.

Identifying local administrator account access (option C) is not the primary purpose of obtaining a baseline image, although it may be a part of the baseline configuration. Local administrator accounts are user accounts that have full control over the operating system and its resources. An IS auditor may identify and review the local administrator accounts to ensure that they are properly secured and authorized, but this does not require obtaining a baseline image.

Verifying the integrity of operating system backups (option D) is not the primary purpose of obtaining a baseline image, although it may be a part of the backup process. Operating system backups are copies of the operating system data and settings that can be used to restore the system in case of failure or disaster. An IS auditor may verify that the operating system backups are complete, accurate, and accessible, but this does not require obtaining a baseline image.

The third-party contract has not been reviewed by the legal department is the auditor’s greatest concern because it poses a significant legal and financial risk to the client. A third-party contract is a legally binding agreement between the client and the outsourced payroll provider that defines the scope, terms, and conditions of the service. A third-party contract should be reviewed by the legal department to ensure that it complies with the applicable laws and regulations, protects the client’s interests and rights, and specifies the roles and responsibilities of both parties. A third-party contract that has not been reviewed by the legal department may contain clauses that are unfavorable, ambiguous, or contradictory to the client, such as:

Inadequate or unclear service level agreements (SLAs) that do not specify the quality, timeliness, and accuracy of the payroll service.

Insufficient or vague security and confidentiality provisions that do not safeguard the client’s data and information from unauthorized access, use, disclosure, or loss.

Unreasonable or excessive fees, penalties, or liabilities that may impose an undue financial burden on the client.

Limited or no audit rights that may prevent the client from verifying the effectiveness and compliance of the payroll provider’s internal controls.

Inflexible or restrictive termination clauses that may limit the client’s ability to cancel or switch to another payroll provider.

A third-party contract that has not been reviewed by the legal department may expose the client to various risks, such as:

Legal disputes or litigation with the payroll provider over contractual breaches or performance issues.

Regulatory fines or sanctions for noncompliance with tax, labor, or other laws and regulations related to payroll.

Financial losses or damages due to errors, fraud, or negligence by the payroll provider.

Reputation damage or customer dissatisfaction due to payroll errors or delays.

Therefore, an IS auditor should be highly concerned about a third-party contract that has not been reviewed by the legal department and recommend that the client seek legal advice before signing or renewing any contract with an outsourced payroll provider.

User access rights have not been periodically reviewed by the client is a moderate concern because it may indicate a lack of proper access control over the payroll system. User access rights are the permissions granted to users to access, view, modify, or delete data and information in the payroll system. User access rights should be periodically reviewed by the client to ensure that they are aligned with the user’s roles and responsibilities, and that they are revoked or modified when a user changes roles or leaves the organization. User access rights that are not periodically reviewed by the client may result in unauthorized or inappropriate access to payroll data and information, which may compromise its confidentiality, integrity, and availability.

Payroll processing costs have not been included in the IT budget is a minor concern because it may indicate a lack of proper planning and allocation of IT resources for payroll processing. Payroll processing costs are the expenses incurred by the client for using an outsourced payroll service, such as fees, charges, taxes, or penalties. Payroll processing costs should be included in the IT budget to ensure that they are adequately estimated, monitored, and controlled. Payroll processing costs that are not included in the IT budget may result in unexpected or excessive costs for payroll processing, which may affect the client’s profitability and cash flow.

The third-party contract does not comply with the vendor management policy is a low concern because it may indicate a lack of alignment between the client’s vendor management policy and its actual vendor selection and evaluation process. A vendor management policy is a set of guidelines and procedures that governs how the client manages its relationship with its vendors, such as how to select, monitor, evaluate, and terminate vendors. A vendor management policy should be consistent with the client’s business objectives, risk appetite, and regulatory requirements. A third-party contract that does not comply with the vendor management policy may result in suboptimal vendor performance or service quality, but it does not necessarily imply a breach of contract or a violation of law.

 The primary advantage of object-oriented technology is enhanced efficiency due to the re-use of elements of logic. Object-oriented technology is a software design model that uses objects, which contain both data and code, to create modular and reusable programs. Objects can be inherited from other objects, which reduces duplication and improves maintainability. Grouping objects into methods for data access, managing sequential program execution for data access, and managing a restricted variety of data types for a data object are not advantages of object-oriented technology. References: ISACA CISA Review Manual 27th Edition, page 304

 The most useful analytical method when trying to identify groups with similar behavior or characteristics in a large population is classification. Classification is a technique that assigns data points to predefined categories or classes based on their features or attributes. Classification can help to discover patterns, trends, and relationships among the data and reveal the similarities or differences among the groups. Classification can also help to support decision making, prediction, or recommendation based on the data analysis. References:

The primary purpose of documenting audit objectives when preparing for an engagement is to identify areas with relatively high probability of material problems. Audit objectives are statements that describe what the audit intends to accomplish or verify during the engagement. Audit objectives help the IS auditor to focus on the key areas of risk or concern, to design appropriate audit procedures and tests, and to evaluate audit evidence and results. By documenting audit objectives, the IS auditor can identify areas with relatively high probability of material problems that may affect the achievement of audit goals or business objectives. Addressing the overall risk associated with the activity under review, ensuring maximum use of audit resources during the engagement and prioritizing and scheduling auditee meetings are also purposes of documenting audit objectives, but they are not as primary as identifying areas with high probability of material problems. References:

Internal firewalls are highly effective for isolating Internet of Things (IoT) devices from corporate network traffic. By segmenting the network and restricting communication between devices and the main corporate infrastructure, internal firewalls help mitigate the risk of lateral movement and data breaches caused by compromised IoT devices.

Blockchain Technology (Option B):This is useful for ensuring data integrity but not for network isolation.

Content Filtering Proxy (Option C):This is designed to manage web traffic and does not provide network segmentation.

Zero Trust Architecture (Option D):While Zero Trust provides robust access controls, internal firewalls are more directly suited for traffic isolation.

The most effective control to mitigate unintentional misuse of authorized access is security awareness training. This is because security awareness training can educate users on the proper use of their access rights, the potential consequences of misuse, and the best practices to protect the confidentiality, integrity, and availability of information systems. Security awareness training can also help users recognize and avoid common threats such as phishing, malware, and social engineering.

Annual sign-off of acceptable use policy, regular monitoring of user access logs, and formalized disciplinary action are not the most effective controls to mitigate unintentional misuse of authorized access. These controls may help deter or detect intentional misuse, but they do not address the root cause of unintentional misuse, which is often a lack of knowledge or awareness of security policies and procedures.

The correct answer is B. Assessing key controls that support the migration.

ISACA guidance explains that internal audit should be involved in cloud procurement, design, and adoption to identify relevant risks and ensure that appropriate controls are in place and operating effectively. That is an assurance role, not a management or implementation role.

Option A is incorrect because mitigating risk to an acceptable level is a management responsibility, not an internal audit responsibility. Internal audit evaluates and provides assurance, but should not own risk treatment in a way that impairs independence.

Option C is incorrect because implementing security controls is also a management or operational responsibility, not the auditor’s role.

Option D is incorrect because budget and resource impact analysis is primarily a management planning function.

Therefore, the correct answer is B, because internal audit’s proper role is to assess whether the key controls supporting the cloud migration are appropriate and effective.

The most effective way to maintain network integrity when using mobile devices is to implement network access control. Network access control is a security control that regulates and restricts access to network resources based on predefined policies and criteria, such as device type, identity, location, or security posture. Network access control can help maintain network integrity when using mobile devices by preventing unauthorized or compromised devices from accessing or affecting network systems or data. The other options are not as effective as network access control in maintaining network integrity when using mobile devices, as they do not address all aspects of network access or security. Implementing outbound firewall rules is a security control that filters and blocks network traffic based on source, destination, protocol, or port, but it does not regulate or restrict network access based on device characteristics or conditions. Performing network reviews is a monitoring activity that evaluates and reports on the performance, availability, or security of network resources, but it does not regulate or restrict network access based on device characteristics or conditions. Reviewing access control lists is a verification activity that validates and confirms the access rights and privileges of network users or devices, but it does not regulate or restrict network access based on device characteristics or conditions. References: CISA Review Manual (Digital Version), Chapter 5, Section 5.2.2

The best answer is B. End users are able to create their own cloud server instances.

The biggest concern is uncontrolled provisioning, because allowing end users to create their own server instances can bypass governance, security baselines, cost controls, asset management, and monitoring. ISACA’s cloud and auditable security guidance emphasizes the importance of strong governance, control over misconfigurations, and consistent security baselines in cloud environments. Unrestricted self-provisioning significantly increases the risk of shadow IT and insecure deployments.

Option A is usually a normal protective arrangement. Option C can be appropriate depending on design and identity strategy. Option D is a governance weakness, but it is less immediate than uncontrolled creation of cloud infrastructure by end users. In audit terms, uncontrolled server creation directly threatens configuration, access control, and accountability.

The greatest concern is whether the increased incident resolution time will adversely affect the organization’s business operations and whether that impact was properly assessed before the contract change. In ISACA terms, service arrangements should be aligned with business needs and service objectives. If a contract change weakens incident response commitments, the key audit concern is not simply the wording of the SLA, but whether management evaluated the resulting business impact. ISACA guidance notes that support agreements and SLAs should be aligned with internal service expectations and business requirements.

Option A is correct because incident resolution times directly affect availability, continuity, user support, and operational resilience. If the contract now permits slower restoration or resolution, the organization may be exposed to longer outages or degraded services. The central risk is whether management made that trade-off knowingly after analyzing the impact on critical business processes. This is the most important concern from an audit and governance perspective.

Option B is not the best answer because noncompliance with IT security policy could be serious, but the question specifically highlights a change in incident resolution time. Unless there is evidence of an actual policy violation, the more direct concern is operational impact on the business.

Option C is also not the greatest concern. In practice, if the contract terms changed, the SLA may need revision or alignment, but that is more of a documentation and governance symptom. The deeper issue is whether the revised service commitments are acceptable to the business. ISACA guidance stresses alignment of support agreements and SLAs with organizational needs.

Option D is the weakest answer because considering alternative cost-reduction methods is a management decision, not the primary audit concern. Auditors focus on risk and control implications, not whether management explored every possible commercial option.

Therefore, A is the best answer because the most significant issue is whether the organization evaluated the impact of slower incident resolution on business processes before accepting the lower-cost contract.

Risk acceptancemeanschoosing not to take immediate actionto mitigate the risk, making it thelowest-costapproach in the short term.

Risk Acceptance (Correct Answer – B)

The organizationacknowledges the riskand decides toaccept itwithout implementing additional controls.

Example:A small companyaccepts the riskof not segregating financial duties due to limited staff.

Risk Mitigation (Incorrect – A)

Involvesapplying security controls, leading to additional costs.

 An IS auditor would be most concerned if process ownership has not been established for the information asset management process, as this would indicate a lack of accountability, responsibility, and authority for managing the assets throughout their lifecycle. The process owner should also ensure that the process is aligned with the organization’s objectives, policies, and standards. The process should require specifying the physicallocations of assets, include asset review, and identify asset value, but these are less critical than establishing process ownership. References: CISA Review Manual (Digital Version), Chapter 3, Section 3.3

 Computer performance is the measure of how well a computer system can execute tasks and applications within a given time frame. Computer performance can be affected by various factors, such as hardware specifications, software configuration, network conditions, and user behavior. To analyze computer performance, it is important to use statistical metrics that can quantify the capacity utilization of the system resources, such as CPU, memory, disk, and network. These metrics can help identify the bottlenecks, inefficiencies, and anomalies that may degrade the performance of the system. Examples of such metrics include CPU utilization, memory usage, disk throughput, network bandwidth, and response time.

The other options are not as useful as statistical metrics when analyzing computer performance. An operations report of user dissatisfaction with response time is a subjective measure that may not reflect the actual performance of the system. Tuning of system software to optimize resource usage is a corrective action that can improve performance, but it is not a method of analysis. A report of off-peak utilization and response time is a limited snapshot that may not capture the peak performance or the average performance of the system.

The most significant benefit of implementing a control self-assessment (CSA) program and leveraging the internal audit function to test its internal controls annually is that risks are detected earlier. A CSA program is a process that enables business owners and managers to assess and improve their own internal controls on a regular basis, without relying on external auditors or consultants. A CSA program can help identify and mitigate risks, enhance performance, increase accountability, and foster a culture of control within the organization. By leveraging the internal audit function to test its internal controls annually, a small business unit can also obtain independent assurance and validation of its CSA results, as well as recommendations for improvement. This approach can help reduce compliance costs, as external audits may be less frequent or extensive. However, this is not the most significant benefit, as compliance costs are only one aspect of the total cost of risk. Business owners can also focus more on their core roles, as they can delegate some of their control responsibilities to their staff or teams through CSA. However, this is not the most significant benefit, as business owners still need to oversee and monitor their CSA activities and results, and ensure that they align with their strategic objectives and priorities. Line management may also be more motivated to avoid control exceptions, as they are directly involved in assessing and improving their own controls through CSA. However, this is not the most significant benefit, as motivation alone may not be sufficient to ensure effective control design and operation. References: Info Technology and Systems Resources | COBIT, Risk, Governance … - ISACA, IT Governance and Process Maturity

A governing body monitors IT performance most effectively when IT performance metrics are aligned with business goals. ISACA’s COBIT-based governance guidance consistently emphasizes that metrics should help leadership and governing bodies monitor the achievement of enterprise business goals and related IT goals. Metrics are useful for governance only when they are connected to what the enterprise is trying to achieve.

Option D is correct because a governing body is responsible for oversight at the strategic level. Strategic oversight depends on understanding whether IT is supporting business objectives, not just whether technical measures are being collected. ISACA states that metrics help management monitor achievements of business-related and IT-related goals.

Option A is useful at an operational or service management level, but it is narrower than business alignment. Service delivery objectives matter, yet the governing body’s concern is broader enterprise value and strategic alignment.

Option B is not the best answer because manufacturer recommendations may help establish technical asset baselines, but they do not ensure metrics support governance needs or enterprise performance oversight.

Option C is attractive because automated, quantitative data improves reliability and efficiency, but automation alone does not guarantee the metrics are the right ones. Governance requires relevant metrics tied to business outcomes, not just easily measured data.

Therefore, D is the best answer because proper alignment between business goals and IT performance metrics is what most enables a governing body to monitor IT performance meaningfully.

Data definition standards within a database primarily support data formatting by establishing how data elements must be structured, represented, and stored. In practical terms, these standards define characteristics such as data type, field length, allowable values, precision, naming conventions, and valid formats. ISACA glossary material includes format checking as a control concept, which directly relates to verifying that data conforms to a prescribed format. That is the closest and strongest match to what data definition standards support.

Option C is correct because data definition standards are about consistency of data structure and representation. When an organization enforces common definitions for fields and attributes, it improves the consistency and usability of data across systems and applications. ISACA governance and data management material emphasizes that defining the format in which data are presented is part of giving data meaning and ensuring quality and usability.

Option A is incorrect because data disposal concerns end-of-life handling of data, such as destruction, archival expiration, and secure deletion. Those activities are governed by retention, records management, privacy, and disposal requirements, not by database data definition standards. ISACA privacy and data lifecycle guidance treats disposal as a separate lifecycle issue.

Option B is incorrect because data retention relates to how long data should be kept for business, legal, regulatory, or operational purposes. Retention policies may rely on data classification and legal obligations, but they are not what data definition standards primarily address.

Option D is incorrect because data confidentiality is mainly supported by access controls, encryption, classification, segregation of duties, and related security controls. Although well-defined data may indirectly help governance, confidentiality is not the main purpose of data definition standards.

Therefore, the best answer is C because enforcing data definition standards within a database most directly supports correct and consistent data formatting.

Hashing is a technique that transforms data into a fixed-length value, called a hash or a digest, that uniquely represents the original data. Hashing can be used to validate the integrity of data communicated between production databases and a big data analytics system by comparing the hash values of the data before and after the communication. If the hash values match, the data has not been altered; if they differ, the data has been tampered with or corrupted. Hashing is a better security control than encrypting, running and comparing the count function, or hosting a digital certificate for this purpose because:

Encrypting in-scope data sets can protect the confidentiality of the data, but not necessarily the integrity. Encryption algorithms can be broken or bypassed by malicious actors, or encryption keys can be compromised or lost. Moreover, encryption adds overhead to the communication process and may affect the performance of the big data analytics system.

Running and comparing the count function within the in-scope data sets can only verify the number of records or elements in the data sets, but not the content or quality of the data. The count function cannot detect any changes or errors in the data values, such as missing, duplicated, corrupted, or manipulated data.

Hosting a digital certificate for in-scope data sets can provide authentication and non-repudiation for the data sources, but not integrity for the data itself. A digital certificate is a document that contains information about the identity and public key of an entity, such as a person, organization, or device. A digital certificate does not contain or verify the actual data that is communicated between production databases and a big data analytics system.

An IS auditor reviewing the threat assessment for a data center would be most concerned if all identified threats relate to external entities. This indicates that the threat assessment is incomplete and biased, as it ignores the potential threats from internal sources, such as employees, contractors, vendors, or authorized visitors. Internal threats can pose significant risks to the data center, as they may have access to sensitive information, systems, or facilities, and may exploit their privileges for malicious or fraudulent purposes. According to a study by IBM, 60% of cyberattacks in 2015 were carried out by insiders1

Some of the identified threats are unlikely to occur is not a cause for concern, as it shows that the threat assessment is comprehensive and realistic, and considers all possible scenarios, regardless of their probability. A threat assessment should not exclude any potential threats based on subjective judgments or assumptions, as they may still have a high impact if they materialize.

The exercise was completed by local management is not a cause for concern, as it shows that the threat assessment is conducted by the people who are most familiar with the data center’s operations, environment, and risks. Local management may have more relevant and accurate information and insights than external parties, and may be more invested in the outcome of the threat assessment.

Neighboring organizations’ operations have been included is not a cause for concern, as it shows that the threat assessment is holistic and contextual, and considers the interdependencies and influences of external factors on the data center’s security. Neighboring organizations’ operations may pose direct or indirect threats to the data center, such as physical damage, network interference, or shared vulnerabilities.

 Incremental backups are backups that only copy the data that has changed since the last backup, whether it was a full or incremental backup. The main reason to use incremental backups is to minimize the backup time and resources, as they require less storage space and network bandwidth than full backups. Incremental backups can also improve key availability metrics, such as recovery point objective (RPO) and recovery time objective (RTO), but that is not their primary purpose. Reducing costs associated with backups and increasing backup resiliency and redundancy are possible benefits of incremental backups, but they depend on other factors, such as the backup frequency, retention policy, and media type. References: CISA Review Manual (Digital Version): Chapter 5 - Information Systems Operations and Business Resilience

While all the options can help reduce the risk of data leakage, providing education and guidelines to employees on the use of social networking sites would be the most effective. This is because it directly addresses the issue at hand - the use of social networking sites for business purposes1. Education and guidelines can help employees understand the risks associated withsocial media use and teach them how to safely and responsibly use these platforms for business purposes1. This includes understanding privacy settings, recognizing phishing attempts, and knowing what information should not be shared on these platforms1.

 The best approach to determine whether IT service delivery is based on consistently effective processes is to evaluate key performance indicators (KPIs). KPIs are measurable values that demonstrate how effectively an organization is achieving its key objectives. KPIs can help the IT governance body to monitor and assess the performance, quality, and efficiency of the IT service delivery processes. KPIs can also help to identify areas for improvement and benchmark against best practices or industry standards. References:

The best recommendation to facilitate compliance with the regulation that requires organizations to report significant security incidents to the regulator within 24 hours of identification is to include the requirement in the incident management response plan. An incident management response plan is a document that defines the roles, responsibilities, procedures, and tools for managing security incidents effectively and efficiently. Including the requirement in the incident management response plan can help ensure that security incidents are identified, classified, reported, and escalated in accordance with the regulation. The other options are not as effective as including the requirement in the incident management response plan, as they do not address all aspects of incident management or compliance. Establishing key performance indicators (KPIs) for timely identification of security incidents is a monitoring technique that can help measure and improve the performance of incident management processes, but it does not ensure compliance with the regulation. Enhancing the alert functionality of the intrusion detection system (IDS) is a technical control that can help detect and notify security incidents faster, but it does not ensure compliance with the regulation. Engaging an external security incident response expert for incident handling is a contingency measure that can help augment the organization’s internal capabilities and resources for managing security incidents, but it does not ensure compliance with the regulation. References: CISA Review Manual (Digital Version), Chapter 4, Section 4.2.2

Using risk assessments to determine areas to be included in an audit plan is a primary benefit because it helps to prioritize the audit activities based on the level of risk and the potential impact of the audit findings. This way, the audit resources, such as time, staff, and budget, can be allocated more efficiently and effectively to the areas that need the most attention and provide the most value.

 The rules of engagement define the scope, objectives, methodology, deliverables, and limitations of the penetration testing. They also specify the legal and ethical boundaries, communication channels, and escalation procedures. Establishing the rules of engagement is the first step when planning to conduct penetration testing for a client, as it ensures that both parties agree on the expectations and outcomes of the testing. The other options are important steps, but they should be done after the rules of engagement are established. References: CISA Review Manual (Digital Version) 1, page 381.

A lack ofMobile Device Management (MDM) enrollmentis the biggest concern, asunmanaged devicespose a serious security risk.

Not All Devices Enrolled in MDM (Correct Answer – C)

Unenrolled devices can bypass security policies.

Example:A stolen, unenrolled device may lack encryption, exposing corporate data.

Biometric Authentication Required (Incorrect – A)

Biometrics are anenhanced security measure, not a concern.

VPN Not Required for Internal Network (Incorrect – B)

VPNs are typically used for external access, not always needed internally.

Remote Wipe Requires Internet (Incorrect – D)

A limitation but stillless riskythan allowing unsecured devices.

The IS auditor should notify audit management of the finding first, as this is a significant issue that may affect the audit scope and objectives. The IS auditor should not notify law enforcement or require the third party to notify customers without consulting audit management first. The audit report with a significant finding should be issued after the audit is completed and the findings are validated. References: ISACA, CISA Review Manual, 27th Edition, 2018, page 247

The biggest risk is reliance on inaccurate or low-quality legal/regulatory information, which could result in compliance failures. Other concerns (paid tier, provider, competitors) are secondary.

Determining accountability of data owners is the most important activity in the data classification process. Data classification is a process that assigns categories or labels to data based on their value, sensitivity, criticality and risk to the organization. Data classification helps to determine the appropriate level of protection, access and retention for data. Determining accountability of data owners is an activity that identifies and assigns roles and responsibilities for data classification, protection and management to individuals or functions within the organization. Data owners are individuals or functions who have authority and responsibility for defining, classifying, protecting and managing data throughout their lifecycle. Determining accountability of data owners is essential for ensuring that data are classified correctly and consistently, and that data classification policies and procedures are followed and enforced. The other options are not as important as option C, as they are dependent on or derived from the accountability of data owners. Labeling the data appropriately is an activity that applies the categories or labels assigned by data owners to data based on their classification criteria. Identifying risk associated with the data is an activity that assesses the potential impact and likelihood of loss, disclosure, modification or destruction of data based on their classification level. Determining the adequacy of privacy controls is an activity that evaluates whether the controls implemented to protect personal or sensitive data are sufficient and effective based on their classification level. References: CISA Review Manual (Digital Version) , Chapter 5: Protection of Information Assets, Section 5.3: Data Classification.

The best method to delete sensitive information from storage media that will be reused is multiple overwriting. This is because multiple overwriting ensures that the data is practically unrecoverable by any software or hardware means. Multiple overwriting involves writing 0s, 1s, or random patterns onto all sectors of the storage media several times, making the original data unreadable or inaccessible. There arevarious software programs available that can securely delete files from storage media using multiple overwriting techniques1.

Crypto-shredding is not the best method because it only works for encrypted data. Crypto-shredding involves deleting the encryption key used to encrypt the data, making the data unreadable and unrecoverable. However, if the data is not encrypted, crypto-shredding will not erase it2.

Reformatting and re-partitioning are not the best methods because they do not erase the data completely. Reformatting and re-partitioning only delete the file system structures and pointers that make the data accessible, but thedata itself remains on the storage media and can be recovered using data recovery software

Recent third-party IS audit reports would be most helpful in determining the effectiveness of the IT governance framework of the target company. IT governance is a framework that defines the roles, responsibilities, and processes for aligning IT strategy with business strategy. A third-party IS audit is an independent and objective examination of an organization’s IT governance framework by an external auditor. Recent third-party IS audit reports can provide reliable and unbiased evidence of the strengths, weaknesses, and maturity of the IT governance framework of the target company. The other options are not as helpful as recent third-party IS audit reports, as they may not be as comprehensive, accurate, or current as external audits. References: CISA Review Manual, 27th Edition, page 94

 The most efficient way to identify segregation of duties violations in a new system is to review a report of security rights in the system. Segregation of duties is a control principle that aims to prevent or detect errors, fraud, or abuse by ensuring that no single individual has the ability to perform incompatible or conflicting functions or activities within a system or process. A report of security rights in the system can provide a comprehensive and accurate overview of the roles, responsibilities, and access levels assigned to different users or groups in the system, and can help to identify any potential segregation of duties violations or risks. The other options are not as efficient as reviewing a report of security rights in the system, because they either rely on observation or testing rather than analysis, or they focus on existing rather than potential violations. References: CISA Review Manual (Digital Version)1, Chapter 5, Section 5.2.2

 Problem management is an IT service management activity that is most likely to help with identifying the root cause of repeated instances of network latency. Problem management involves analyzing incidents that affect IT services and finding solutions to prevent them from recurring or minimize their impact. Change management is an IT service management activity that involves controlling and documenting any modifications to IT services or infrastructure. Incident management is an IT service management activity that involves restoring normal service operation as quickly as possible after an incident has occurred. Configuration management is an IT service management activity that involves identifying and maintaining records of IT assets and their relationships. References: ISACA, CISA Review Manual, 27th Edition, 2018, page 334

The best indicator of whether a PIR performed by the PMO was effective is whether project outcomes have been realized. Project outcomes are the benefits or value that a project delivers to its stakeholders, such as improved efficiency, quality, customer satisfaction, or revenue. A PIR should evaluate whether project outcomes have been achieved in accordance with project objectives, scope, budget, and schedule. The other options are not as good as project outcomes in determining the effectiveness of a PIR. Lessons learned are valuable inputs for improving future projects, but they do not measure whether project outcomes have been realized. Management approval of the PIR report is a sign of acceptance and support for the PIR findings and recommendations, but it does not reflect whether project outcomes have been achieved. The review performed by an external provider is a way of ensuring objectivity and independence for the PIR, but it does not guarantee whether project outcomes have been realized. References: CISA Review Manual (Digital Version), Chapter 3, Section 3.3

Data collection and obtaining consentis themost critical regulatory requirementwhen using customer data for AI training, especially under laws likeGDPR, CCPA, and ISO 27701.

 IT performance measures are indicators of how well an organization is achieving its IT goals and objectives. Benchmarking surveys are useful tools for comparing an organization’s IT performance measures with those of other organizations in the same industry or sector. Benchmarking surveys can provide insights into best practices, gaps, trends, and opportunities for improvement. IT governance frameworks, utilization reports, and balanced scorecards are not as helpful for comparing ITperformance measures across organizations, as they may vary in scope, methodology, and terminology. References: IT Resources | Knowledge and Insights | ISACA, CISA Review Manual (Digital Version)

The correct answer is D. Maintenance procedures should be considered when examining fire suppression systems as part of a data center environmental controls review. Fire suppression systems are critical for protecting the data center equipment and personnel from fire hazards. Therefore, they should be regularly maintained and tested to ensure their proper functioning and compliance with safety standards. Maintenance procedures should include inspection, cleaning, replacement, and repair of the fire suppression system components, as well as documentation of the maintenance activities and results. Installation manuals, onsite replacement availability, and insurance coverage are notdirectly related to the fire suppression system performance and effectiveness, and therefore are not relevant for the audit review. References: CISA Review Manual (Digital Version)1, page 403.

The finding that should be ranked as the highest risk is that network penetration tests are not performed. Network penetration tests are simulated cyberattacks that aim to identify and exploit the vulnerabilities and weaknesses of the network security controls, such as firewalls, routers, switches, servers, and devices. Network penetration tests are essential for assessing the effectiveness and resilience of the network security posture, and for providing recommendations for improvement and remediation. If network penetration tests are not performed, the organization may not be aware of the existing or potential threats and risks to its network, and may not be able to prevent or respond to real cyberattacks, which can result in data breaches, service disruptions, financial losses, reputational damage, and legal or regulatory penalties. The other findings are also important, butnot as risky as the lack of network penetration tests, because they either do not directly affect the networksecurity controls, or they can be addressed by documentation or approval processes. References: CISA Review Manual (Digital Version)1, Chapter 5, Section 5.2.4

 Enterprise architecture (EA) is the most helpful to an IS auditor reviewing the alignment of planned IT budget with the organization’s goals and strategic objectives. EA is a well-defined practice for conducting enterprise analysis, design, planning, and implementation, using a comprehensive approach at all times, for the successful development and execution of strategy1. EA provides a blueprint for an effective IT strategy and guides the controlled evolution of IT in a way that delivers business benefit in a cost-effective way2. By reviewing the EA, the IS auditor can evaluate how well the planned IT budget supports the business vision, strategy, objectives, and capabilities of the organization.

The other options are not as helpful as EA for reviewing the alignment of planned IT budget with the organization’s goals and strategic objectives. BIA is a process of determining the criticality of business activities and associated resource requirements to ensure operational resilience and continuity of operations during and after a business disruption3. BIA quantifies the impacts of disruptions on service delivery, risks to service delivery, and recovery time objectives (RTOs) and recovery point objectives (RPOs)3. BIA is useful for developing strategies, solutions, and plans for business continuity and disaster recovery, but it does not directly address the alignment of planned IT budget with the organization’s goals and strategic objectives. Risk assessment report is a document that contains the results of performing a risk assessment or the formal output from the process of assessing risk4. Risk assessment is a method to identify, analyze, and control hazards and risks present in a situation or a place5. Risk assessment report is useful for identifying and mitigating potential threats and issues that are detrimental to the business or an enterprise, but it does not directly addressthe alignment of planned IT budget with the organization’s goals and strategic objectives. Audit recommendations are guidance that highlights actions to be taken by management6. When implemented, process risks should be mitigated, and performance should be enhanced6. Audit recommendations are useful for improving the quality and reliability of the information system and its outputs, but they do not directly address the alignment of planned IT budget with the organization’s goals and strategic objectives. Therefore, option A is the correct answer.

Reviewing the application implementation documents is the best way for an IS auditor to assess the design of an automated application control. An automated application control is a control that is embedded in the application software and is executed by the system without human intervention. An automated application control is designed to ensure the accuracy, completeness, validity, and authorization of transactions and data processed by the application. Examples of automated application controls are input validation, edit checks, calculations, reconciliations, and exception reports.

The application implementation documents are the documents that describe the design specifications, logic, and functionality of the application and its controls. The application implementation documents may include:

Business requirements document - a document that defines the business objectives, needs, and expectations of the application.

Functional specifications document - a document that describes the features, functions, and interfaces of the application and its controls.

Technical specifications document - a document that details the technical architecture, design, and configuration of the application and its controls.

Test plan and test cases - a document that outlines the testing strategy, methodology, and scenarios for verifying the functionality and performance of the application and its controls.

User manual and training material - a document that provides instructions and guidance on how to use the application and its controls.

By reviewing the application implementation documents, an IS auditor can:

Gain an understanding of the purpose, scope, and nature of the application and its controls.

Evaluate whether the application and its controls are designed to meet the business requirements and objectives.

Identify any gaps, inconsistencies, or errors in the design of the application and its controls.

Compare the design of the application and its controls with the best practices and standards in the industry.

Determine whether the application and its controls are adequately tested and documented.

Interviewing the application developer is not the best way for an IS auditor to assess the design of an automated application control. An interview is a verbal communication technique that involves asking questions and listening to responses. An interview can be useful for obtaining general information or clarifying specific issues related to the application and its controls. However, an interview alone cannot provide sufficient evidence or documentation to support the auditor’s assessment of the design of an automated application control. An interview may also be subject to bias, misunderstanding, or misinterpretation by either party.

Obtaining management attestation and sign-off is not the best way for an IS auditor to assess the design of an automated application control. Management attestation and sign-off is a formal process that involves obtaining written confirmation from management that they have reviewed and approved the design of the application and its controls. Management attestation and sign-off can indicate management’s commitment and accountability for the quality and effectiveness of the application and its controls. However, management attestation and sign-off cannot substitute for an independent and objective evaluation by an IS auditor. Management attestation and sign-off may also be influenced by pressure, conflict of interest, or fraud.

Reviewing system configuration parameters and output is not the best way for an IS auditor to assess the design of an automated application control. System configuration parameters are settings that define how the system operates or interacts with other components. System output is data or information that is produced by the system as a result of processing transactions or performing functions. Reviewing system configuration parameters and output can help an IS auditor to verify whether the system is configured correctly and whether it produces accurate and reliable output. However, reviewing system configuration parameters and output cannot provide a comprehensive view of how the application and its controls are designed to achieve their objectives. Reviewing system configuration parameters and output may also require technical expertise or access rights that may not be available to an IS auditor.

The statement that BEST demonstrates alignment with data classification standards related to the protection of information assets is D. All information assets will be assigned a clearly defined level to facilitate proper employee handling. Data classification involves categorizing information assets based on their sensitivity, importance, and usage. Assigning clearly defined levels (such as public, internal, confidential, etc.) to information assets ensures that appropriate security controls are applied based on their classification. By doing so, organizations can manage access, encryption, and other protective measures effectively12.

 The advantage of using agile software development methodology over the waterfall methodology is that it allows for quicker deliverables. Agile software development is an iterative and incremental approach that emphasizes customer feedback, collaboration, and adaptation. Agile software development delivers working software in short cycles, called sprints, that typically last from two to four weeks. This enables the development team to respond to changing requirements, deliver value faster, and improve quality. Waterfall software development is a linear and sequential approach that follows a predefined set of phases, such as planning, analysis, design, implementation, testing, and maintenance. Waterfall software development requires a clear and stable definition of the project scope, deliverables, and expectations before starting the development process. Waterfall software development can be slow, rigid, and costly, especially if changes occur during the later stages of the project. References: CISA Review Manual (Digital Version), Chapter 3: Information Systems Acquisition, Development and Implementation, Section 3.1: Project Management Practices

A mirror backup is a type of backup that creates an exact copy of the source data to the destination, without using any compression or encryption. A mirror backup is the best backup scheme to recommend given the need for a shorter restoration time in the event of a disruption, because it allows for the fastest and easiest recovery of data. A mirror backup does not store any previous versions of the files, so it only reflects the current state of the source data. Therefore, a mirror backup requires less storage space than a full backup, but more than an incremental or differential backup.

A differential backup is a type of backup that stores the changes made to the source data since the last full backup. A differential backup requires less storage space and time than a full backup, but more than an incremental backup. However, a differential backup also requires more time and resources to restore than a mirror or full backup, because it needs to combine the last full backup and the latest differential backup to recover the data.

A full backup is a type of backup that copies all the files and folders from the source data to the destination, regardless of whether they have changed or not. A full backup provides the most complete protection of data and the simplest recovery process, but it also requires the most storage space and time to perform. A full backup is usually done periodically, such as weekly or monthly, and followed by incremental or differential backups.

An incremental backup is a type of backup that stores the changes made to the source data since the last backup, whether it was a full or an incremental backup. An incremental backup requires the least storage space and time to perform, but it also requires the most time and resources to restore, because it needs to combine all the previous backups in chronological order to recover the data.

 The auditor’s best course of action in this situation is to notify the audit manager. The audit manager is responsible for overseeing the audit follow-up process and ensuring that audit issues are resolved in a timely and satisfactory manner. The audit manager can then decide whether to escalate the matter to higher authorities, such as the chair of the audit committee, or to accept management’s decision and close the audit finding. The other options are not appropriate for the auditor to do without consulting with the audit manager first. Notifying the chair of the audit committee is a drastic step that may undermine the relationship between the auditor and management, and it should be done only after exhausting other means of resolving the issue. Retesting the control is not necessary, as management has already decided not to implement therecommendations. Closing the audit finding is premature, as management’s decision may not be aligned with the audit objectives or risk appetite. References: CISA Review Manual (Digital Version), Chapter 2, Section 2.4

 The primary reason for an IS auditor to conduct post-implementation reviews is to determine whether project objectives in the business case have been achieved. A post-implementation review is an audit activity that evaluates whether a project has delivered its expected outcomes or benefits in accordance with its objectives, scope, budget, and schedule. A business case is a document that defines and justifies the need, value, and feasibility of a project. A post-implementation review can help assess whether project objectives in the business case have been achieved by comparing actual results with planned expectations and identifying any gaps or deviations. The other options are not primary reasons for conducting post-implementation reviews, as they do not measure whether project objectives in the business case have been achieved. Ensuring key stakeholder sign-off has been obtained is a project closure activity that confirms that all project deliverables have been completed and accepted by key stakeholders, but it does not evaluate whether project objectives in the business case have been achieved. Aligning project objectives with business needs is a project initiation activity that ensures that the project is aligned with the organization’s strategy, goals, and priorities, but it does not evaluate whether project objectives in the business case have been achieved. Documenting lessons learned to improve future project delivery is a project learning activity that captures and shares the knowledge, experience, and feedback gained from the project, but it does not evaluate whether project objectives in the business case have been achieved. References: CISA Review Manual (Digital Version), Chapter 3, Section 3.3

The answer B is correct because the most important thing for an IS auditor to review when determining whether IT investments are providing value to the business is the business strategy. The business strategy is the plan or direction that guides the organization’s decisions and actions to achieve its goals and objectives. The business strategy defines the organization’s vision, mission, values, competitive advantage, target market, value proposition, and key performance indicators (KPIs).

IT investments are the expenditures or costs incurred by the organization to acquire, develop, maintain, or improve its IT assets, such as hardware, software, network, data, or services. IT investments can help the organization to support its business processes, operations, functions, and capabilities. IT investments can also help the organization to create or enhance its products, services, or solutions for its customers or stakeholders.

To determine whether IT investments are providing value to the business, an IS auditor needs to review how well the IT investments align with and contribute to the business strategy. Alignment means that the IT investments are consistent and compatible with the business strategy, and that they support and enable the achievement of the strategic goals and objectives. Contribution meansthat the IT investments are effective and efficient in delivering the expected outcomes and benefits for the business, and that they generate a positive return on investment (ROI) or value for money.

An IS auditor can use various methods or frameworks to review the alignment and contribution of IT investments to the business strategy, such as:

Balanced scorecard: A balanced scorecard is a tool that measures and monitors the performance of an organization across four perspectives: financial, customer, internal process, and learning and growth. A balanced scorecard can help an IS auditor to evaluate how well the IT investments support and improve each perspective of the organization’s performance, and how they link to the organization’s vision and strategy.

Value chain analysis: A value chain analysis is a tool that identifies and analyzes the primary and support activities that add value to an organization’s products or services. A value chain analysis can help an IS auditor to assess how well the IT investments enhance or optimize each activity of the value chain, and how they create or sustain a competitive advantage for the organization.

Business case analysis: A business case analysis is a tool that evaluates the feasibility, viability, and desirability of a proposed project or initiative. A business case analysis can help an IS auditor to examine how well the IT investments address a business problem or opportunity, how they deliver the expected benefits and outcomes for the stakeholders, and how they compare with alternative options or solutions.

The other options are not as important as option B. Return on investment (ROI) (option A) is a metric that measures the profitability or efficiency of an investment by comparing its benefits or returns with its costs or expenses. ROI can help an IS auditor to quantify the value of IT investments for the business, but it does not capture all aspects of value, such as quality, satisfaction, or impact. ROI also depends on how well the IT investments align with the business strategy in the first place. Business cases (option C) are documents that justify and support a proposed project or initiative by describing its objectives, scope, benefits, costs, risks, and alternatives. Business cases can help an IS auditor to understand the rationale and expectations for IT investments, but they do not guarantee that the IT investments will actually deliver the desired value for the business. Business cases also need to be aligned with the business strategy to ensure their relevance and validity. Total cost of ownership (TCO) (option D) is a metric that measures the total costs incurred by an organization to acquire, operate, maintain, and dispose of an IT asset over its life cycle. TCO can help an IS auditor to estimate the financial impact of IT investments for the business, but it does not reflect the benefits or outcomes of IT investments, nor does it indicate how well the IT investments support or enable the business strategy.

High employee turnover (A) poses the greatest risk because it leads to knowledge loss, operational disruptions, and potential security risks from departing employees. A constantly changing workforce can also impact compliance, training, and overall IT stability.

Other options:

Lack of customer satisfaction surveys (B) is a business issue but not a critical IT risk.

Aging staff (C) may be a long-term risk but does not have an immediate impact.

Frequent software upgrades (D) can be beneficial if managed correctly.

The first step in ensuring secure configuration of new IT assets is to establish the baseline configuration requirements those assets must meet. ISACA guidance supports the use of documented security configuration standards, secure baselines, and hardening requirements before deployment. Without predefined hardening standards, vulnerability scanning or remediation lacks a clear benchmark for what “secure” should look like.

Option B is correct because defining and implementing hardening standards establishes the secure baseline for systems, operating systems, applications, and devices. ISACA material notes that resources should adhere to a minimum-security baseline composed of standard security configurations, and secure configurations should be documented and maintained. This makes hardening standards the logical and control-oriented first step.

Option A is not first. Identifying and remediating vulnerabilities is important, but this activity should follow the establishment of hardening standards. Otherwise, there is no approved baseline against which to assess and remediate deviations. In CISA logic, standards come before testing against standards.

Option C is also not first for the same reason. Vulnerability scanning is an assessment technique, but organizations must first define the secure configuration baseline or hardening standard to know what they expect from the asset. Scanning should validate configuration and identify weaknesses after standards have been established.

Option D is clearly incorrect because purchasing tools is not the starting point of good control design. Tools may support implementation and verification, but governance requires that standards be defined first. In ISACA terms, sound control begins with policy, standards, and procedures, not with tool acquisition.

Therefore, the best answer is B because secure configuration starts with defining and applying hardening standards, which then enable scanning, validation, and remediation activities.

The greatest risk if two users have concurrent access to the same database record is data integrity. Data integrity is the property that ensures that the data is accurate, complete, consistent, and valid throughout its lifecycle. If two users have concurrent access to the same database record, they may modify or delete the data in a conflicting or inconsistent manner, resulting in data corruption, loss, or duplication. This can affect the reliability and quality of the data, and cause errors or anomalies in the database operations and functions. The IS auditor should verify that the database has adequate controls to prevent or resolve concurrent access issues, such as locking mechanisms, transaction isolation levels, concurrency control protocols, or timestamping methods. References: CISA Review Manual (Digital Version)1, Chapter 5, Section 5.2.7

Unauthorized changes can be moved into production is the best concern that is addressed by securing production source libraries. Production source libraries contain the source code of programs that are used in the production environment. Securing production source libraries means implementing access controls, change management procedures, and audit trails to prevent unauthorized or improper changes to the source code that could affect the functionality, performance, or security of the production programs. The other options are less relevant concerns that may not be directly addressed by securing production source libraries, but rather by other controls such as program approval, version control, or change testing. References:

CISA Review Manual (Digital Version), Chapter 4, Section 4.2.3.21

 The first step in assessing the controls within a newly implemented call center is to evaluate the operational risk associated with the call center. This will help the IS auditor to identify the potential threats, vulnerabilities, and impacts that could affect the call center’s objectives, performance, and availability. The evaluation of operational risk will also provide a basis for determining the scope, objectives, and approach of the audit. The other options are possible audit procedures, but they are not the first step in the audit process. References: ISACA Frameworks: Blueprints for Success, CISA Review Manual (DigitalVersion)

The best answer is D. Compliance audit.

The auditor is testing whether employee behavior complies with organizational rules or policy regarding the use of the organization’s car. ISACA defines IT compliance as adherence to mandated requirements from laws, regulations, contractual obligations, and internal policies. Since the scenario is about checking whether employees are following the organization’s rule on permitted use, the audit is primarily a compliance-oriented review.

Option A could be tempting because misuse of a company car might be abusive, but the question does not say the auditor is investigating intentional deception or a suspected fraud scheme. Option B is incorrect because this is not primarily about fair presentation of financial statements. Option C is not the best fit because the audit objective is not evaluation of business function performance, but adherence to policy.

Therefore, the correct answer is D, because the auditor is determining whether employees are complying with the organization’s established usage rules.

References (Official ISACA):

ISACA, IT Compliance — compliance includes adherence to internal policies.

ISACA, An Integrated Approach to Security Audits — audits assess adherence to required controls and obligations.

Monitoring systems rely heavily on thresholds to detect anomalies or incidents. If thresholds can be changed without proper change management controls, the entire system’s reliability is compromised because unauthorized or improper changes could either suppress critical alerts or generate excessive false positives. While senior management review (A) is important for governance, it does not directly affect the accuracy of monitoring results. Periodic threshold updates (B) are actually good practice as long as they are controlled. Third-party configuration (D) can be acceptable if properly governed. ISACA’s COBIT BAI06 (Managed IT Changes) stresses that all changes to production systems—including monitoring thresholds—must follow formal change control processes to maintain integrity and reliability.

References (ISACA): COBIT® 2019, BAI06 Managed IT Changes.

The best answer is C. Review audit planning documents.

Before an audit project starts, senior audit leadership must ensure the engagement has been adequately planned. Reviewing planning documents is the control point that lets leadership confirm the objective, scope, risk focus, resourcing, timing, and methodology are appropriate before fieldwork begins. This is the broadest and most essential oversight activity among the choices.

Option A can be part of governance in some audit functions, but direct scope signoff is narrower than review of the full planning package. Option B and D may occur depending on the audit approach, but they are not mandatory leadership actions in every case. The most defensible answer is leadership review of the planning documents because it establishes readiness and oversight before the project begins.

References (Official ISACA):

ISACA, CISA Exam Content Outline — audit planning and execution are structured and risk-based.

ISACA, An Appropriate Approach for Program and Project Management — supports structured planning and oversight before execution.

The best way for an organization to mitigate the risk associated with third-party application performance is to utilize performance monitoring tools to verify service level agreements (SLAs). Performance monitoring tools are software or hardware devices that measure and report the performance of an application or system, such as speed, availability, reliability, etc. Performance monitoring tools can help mitigate the risk associated with third-party application performance, by allowing the organization to verify whether the third-party provider is meeting the SLAs, which are contracts or agreements that define the expected level and quality of service for an application or system. Performance monitoring tools can also help identify and resolve any performance issues or problems that may arise from the third-party application. Ensuring the third party allocates adequate resources to meet requirements is a possible way to mitigate the risk associated with third-party application performance, but it is not the best one, as it may not be feasible or effective depending on the availability, cost, and suitability of the resources. Using analytics within the internal audit function is a possible way to mitigate the risk associated with third-party application performance, but it is not the best one, as it may not be timely or relevant depending on the frequency, scope, and quality of the analytics. Conducting a capacity planning exercise is a possible way to mitigate the risk associated with third-party application performance, but it is not the best one, as it may not be accurate or reliable depending on the assumptions, methods, and data used for the capacity planning.

A firewall is a device or software that monitors and controls the incoming and outgoing network traffic based on predefined rules. A firewall can help protect an organization’s network and information systems from unauthorized or malicious access, by filtering or blocking unwanted or harmful packets. The most important thing for an IS auditor to verify when evaluating an organization’s firewall is that the logs are being collected in a separate protected host. Logs are records of events or activities that occur on a system or network, such as connections, requests, responses, errors, and alerts. Logs can provide valuable information for auditing, monitoring, troubleshooting, and investigating security incidents. However, logs can also be tampered with, deleted, or corrupted by attackers or insiders who want to hide their tracks or evidence of their actions. Therefore, it is essential that logs are stored in a separate host that is isolated and secured from the network and the firewall itself, to prevent unauthorized access or modification of the logs. Automated alerts are being sent when a risk is detected is a good practice for enhancing the security and efficiency of a firewall, but it is not the most important thing for an IS auditor to verify, as alerts may not always be accurate, timely, or actionable. Insider attacks are being controlled is a desirable outcome for a firewall, but it is not the most important thing for an IS auditor to verify, as insider attacks may involve other factors or methods that bypass or compromise the firewall, such as social engineering, credential theft, or physical access. Access to configuration files is restricted is a critical control for ensuring the security and integrity of a firewall, but it is not the most important thing for an IS auditor to verify, as configuration files may not reflect the actual state or performance of the firewall. 

This is because the business processes are the core activities and functions that enable the organization to achieve its objectives and create value for its stakeholders. The business processes are also the sources and drivers of various risks that may affect the organization’s performance, compliance, and reputation. Therefore, the IS auditor should focus on understanding, assessing, and prioritizing the business processes that are most critical, complex, or vulnerable to the organization’s success, and align the audit objectives, scope, and resources accordingly12.

Critical business applications (A) are not the most important area of focus for an IS auditor when developing a risk-based audit strategy, but rather a specific aspect of the business processes that may require attention. Critical business applications are the software systems that support the execution and automation of the business processes, such as enterprise resource planning (ERP), customer relationship management (CRM), or accounting systems. Critical business applications may pose significant risks to the organization if they are not reliable, secure, or efficient. Therefore, the IS auditor should consider the criticality, functionality, and dependency of the business applications when planning the audit, but not as the primary focus12.

Existing IT controls © are not the most important area of focus for an IS auditor when developing a risk-based audit strategy, but rather an outcome or output of the risk assessment process. Existing IT controls are the policies, procedures, practices, and technologies that are implemented to manage and mitigate the IT-related risks that may affect the organization’s business processes and objectives. Existing IT controls may vary in their design, effectiveness, and maturity. Therefore, the IS auditor should evaluate and testthe existing IT controls as part of the audit execution and reporting process, but not as the main focus12.

Recent audit results (D) are not the most important area of focus for an IS auditor when developing a risk-based audit strategy, but rather an input or source of information for the risk assessment process. Recent audit results are the findings, recommendations, and opinions of previous audits that may provide insights or feedback on the organization’s business processes, risks, and controls. Recent audit results may also indicate any changes or trends in the organization’s risk profile or environment. Therefore, the IS auditor should review and consider the recent audit results as part of the audit planning and scoping process, but not as the main focus12.

The greatest concern with the IT department and internal IS audit function both reporting to the CIO is the potential compromise of IS audit independence. Auditor independence refers to the impartiality and objectivity of an auditor in conducting an audit, free from conflicts of interest and bias1. It is crucial for ensuring the quality and reliability of financial reporting1. If the IS audit function reports to the CIO, who also oversees the IT department, it could create a conflict of interest that might compromise the impartiality and objectivity of the IS audit function.

The best answer is A. Release management.

In continuous delivery, code moves frequently from development toward production, but the key control point that connects development output to live production deployment is release management. ISACA explains that continuous delivery takes integration output that has met release criteria and updates the application in production. That means the practical bridge between development and production is the release process that governs packaging, approval, timing, and movement into production.

Option C. DevOps is closely related, but it is broader than the specific connector. ISACA describes DevOps as focusing on automation and integration of processes before and after software release into production. That makes DevOps the broader operating model, while release management is the specific connector between development and production in the delivery pipeline.

Option B. Log management is important for monitoring and troubleshooting, but it does not connect development to production.

Option D. Data management is also important, but it is not the delivery bridge in this context.

Therefore, the correct answer is A, because release management is the function that controls and enables the movement of approved changes from development into production.

An outsourced accounting application has the most inherent risk and should be prioritized during audit planning because it involves external parties, sensitive data, and complex transactions that are susceptible to material misstatement, error, or fraud12. An outsourced accounting application also requires more oversight and monitoring from the internal audit department to ensure compliance with the service level agreement and the organization’s policies and standards3.

 A database administrator (DBA) should be prevented from having end user responsibilities to avoid a conflict of interest and a violation of the principle of segregation of duties. End user responsibilities may include initiating transactions, authorizing transactions, recording transactions or reconciling transactions. A DBA who has end user responsibilities may compromise the integrity, confidentiality and availability of the data and the database systems. Accessing sensitive information, having access to production files and using an emergency user ID are not end user responsibilities, but rather potential risks or controls associated with the DBA role. References:

The greatest concern for an IS auditor reviewing a network printer disposal process is that evidence is not available to verify printer hard drives have been sanitized prior to disposal. This can expose sensitive data to unauthorized parties and cause data breaches. Disposal policies and procedures not being consistently implemented or business units being allowed to dispose printers directly to vendors are compliance issues, but not as critical as data protection. Inoperable printers being stored in an unsecured area is a physical security issue, but not as severe as data leakage. References: ISACA, CISA Review Manual, 27th Edition, 2018, page 387

 The effectiveness of a risk management program can be measured by how well it reduces the residual risk, which is the risk that remains after applying controls, to an acceptable level. Inherent risk is the risk that exists before applying any controls, and it cannot be eliminated completely. Control risk is the risk that the controls fail to prevent or detect a risk event, and it is a component of residual risk. Overall risk is not a meaningful metric for assessing the effectiveness of a risk management program, as it does not account for the impact and likelihood of different risk events. References: CISA Review Manual (Digital Version), Chapter 1, Section 1.2.2

Obtaining management’s consent to the testing scope in writing is the most important step prior to finalizing the scope of testing, as it ensures that the penetration testers have the authorization and approval to perform the testing activities. It also protects them from any legal liabilities or accusations of unauthorized access or damage. The other options are not as important as obtaining management’s consent, and they may vary depending on the specific situation and agreement. For example, some systems may not be excluded from the testing scope, and some tests may not be restricted to the test environment. References: CISA Review Manual (Digital Version) 1, page 381-382.

Segregation of duties (SOD) is a core internal control and an essential component of an effective risk management strategy. SOD emphasizes sharing the responsibilities of key business processesby distributing the discrete functions of these processes to multiple people and departments, helping to reduce the risk of possible errors and fraud1.

SOD is especially important in IT security, where granting excessive system access to one person or group can lead to harmful consequences, such as data breaches, identity theft, or bypassing security controls2. SOD breaks IT-related tasks into four separate function categories: authorization, custody, recordkeeping, and reconciliation1. Ideally, no one person or department holds responsibility in multiple categories.

In a role-based environment, where access privileges are granted based on predefined roles, it is important to ensure that the roles are designed and assigned in a way that supports SOD. For example, the person who develops an application should not also be the one who tests it, deploys it, or maintains it.

Therefore, an application developer should not be assigned the roles of IT operator, system administration, or database administration, as these roles may conflict with their development role and create opportunities for misuse or abuse of the system. The only role that may be assigned to an application developer without violating SOD is emergency support, which is a temporary role that allows the developer to access the system in case of a critical issue that requires immediate resolution3. However, even this role should be granted with caution and monitored closely to ensure compliance with SOD policies.

 The first thing that an IS auditor should review when finding that transaction processing times in an order processing system have significantly increased after a major release is stress testing results. Stress testing is a type of testing that evaluates how a system performs under extreme or abnormal conditions, such as high volume, load, or concurrency of transactions. Stress testing results can help explain why transaction processing times in an order processing system have significantly increased after a major release by revealing any bottlenecks, limitations, or errors in the system’s capacity, performance, or functionality under stress. The other options are not as relevant as stress testing results in explaining why transaction processing times in an order processing system have significantly increased after a major release, as they do not directly measure how the systemperforms under extreme or abnormal conditions. Capacity management plan is a document that defines and implements the processes and activities for ensuring that the system has adequate resources and capabilities to meet current and future demands. Training plans are documents that define and implement the processes and activities for ensuring that the system users have adequate skills and knowledge to use the system effectively and efficiently. Database conversion results are outcomes or outputs of transforming data from one format or structure to another to suit the system’s requirements or specifications. References: CISA Review Manual (DigitalVersion), Chapter 3, Section 3.3

 When an IS audit reveals that a firewall was unable to recognize a number of attack attempts, the auditor’s best recommendation is to place an intrusion detection system (IDS) between the firewall and the Internet, as this would provide an additional layer of security and alert the organization of any malicious traffic that bypasses or penetrates the firewall. Placing an IDS between the firewall and the demilitarized zone (DMZ), the organization’s web server, or the organization’s network would not be as effective, as it would only monitor the traffic that has already passed through the firewall. References: CISA Review Manual (DigitalVersion), Chapter 5, Section 5.4.3

 The business process supported by the system is the most important factor for an IS auditor to understand when planning an audit to assess application controls of a cloud-based system. An IS auditor should have a clear understanding of the business objectives, requirements, and risks of the process, as well as the expected outputs and outcomes of the system. This will help the IS auditor to determine the scope, objectives, and criteria of the audit, as well as to identify and evaluate the key application controls that ensure the effectiveness, efficiency, and reliability of the process. The other options are less important factors that may provide additional information or context for the audit, but not its primary focus. References:

CISA Review Manual (Digital Version), Chapter 5,Section 5.31

The primary reason for an IS auditor to use data analytics techniques is to reduce detection risk. Detection risk is the risk that an IS auditor will fail to detect material errors or irregularities in the information systems environment. By using data analytics techniques, such as data extraction, analysis, visualization, and reporting, an IS auditor can enhance the audit scope, coverage, efficiency, and effectiveness. Data analytics techniques can help an IS auditor to identify anomalies, patterns, trends, correlations, and outliers in large volumes of data that may indicate potential issues or risks. Technology risk, control risk, and inherent risk are types of audit risk that are not directly affected by the use of data analytics techniques by an IS auditor. References: [ISACA Journal Article: Data Analytics for Auditors]

The best course of action for an IS auditor when an auditee is unable to close all audit recommendations by the time of the follow-up audit is to evaluate the residual risk due to open issues. Residual risk is the risk that remains after the implementation of controls or mitigating actions. Evaluating the residual risk due to open issues can help the IS auditor assess the impact and likelihood of the potential threats and vulnerabilities that have not been addressed by the auditee, as well as the adequacy and effectiveness of the existing controls or mitigating actions. Evaluating the residual risk due to open issues can also help the IS auditor prioritize and communicate the open issues to the auditee and other stakeholders, such as senior management or audit committee, and recommend appropriate actions or escalation procedures.

Ensuring the open issues are retained in the audit results is a course of action for an IS auditor when an auditee is unable to close all audit recommendations by the time of the follow-up audit, but it is not the best one. Ensuring the open issues are retained in the audit results can help the IS auditor document and report the status and progress of the audit recommendations, as well as provide a basis for future follow-up audits. However, ensuring the open issues are retained in the audit results does not provide an analysis or evaluation of the residual risk due to open issues, which is more important for informing decision-making and action-taking.

Terminating the follow-up because open issues are not resolved is not a course of action for an IS auditor when an auditee is unable to close all audit recommendations by the time of the follow-up audit, but rather a consequence or outcome of it. Terminating the follow-up because open issues are not resolved may indicate that the auditee has failed to comply with the agreed-upon actions or deadlines, or that the IS auditor has encountered significant obstacles or resistance from the auditee. Terminating the follow-up because open issues are not resolved may also trigger further actions or sanctions from the IS auditor or other authorities, such as issuing a qualified or adverse opinion, withholding certification, or imposing penalties.

Recommending compensating controls for open issues is not a course of action for an IS auditor when an auditee is unable to close all audit recommendations by the time of the follow-up audit, but rather a possible outcome or result of it. Compensating controls are alternative or additional controls that are implemented to reduce or eliminate the risk associated with a weakness or deficiency in another control. Recommending compensating controls for open issues may be appropriate when the auditee is unable to implement the original audit recommendations due to technical, operational,financial, or other constraints, and when the compensating controls can provide a similar or equivalent level of assurance. However, recommending compensating controls for open issues requires a prior evaluation of the residual risk due to open issues, which is more important for determining whether compensating controls are necessary and feasible.

 Reviewing a sample of system-generated backup logs is the best step to verify that regularly scheduled backups are timely and run to completion. Backup logs are records that document the details and results of backup operations, such as the date, time, duration, status, errors, and exceptions. By reviewing a sample of backup logs, the IS auditor can check whether the backups are performed according to the schedule and whether they are completed successfully or not. The other steps do not provide as much evidence or assurance as reviewing backup logs, as they do not show the actual outcome or performance of backup operations. References: CISA Review Manual, 27th Edition, page 247

 Capacity management is a process that ensures that the IT resources of an organization are sufficient to meet the current and future demands of the business. Capacity management enables organizations to identify the extent to which components need to be upgraded, by monitoring and analyzing the performance, utilization, and availability of the IT components, such as servers, networks, storage, applications, etc., and identifying any bottlenecks, gaps, or risks that may affect the service level agreements (SLAs) or quality of service (QoS). Capacity management also helps organizations to plan and optimize the use of IT resources, by forecasting the future demand and growth of the business, and aligning the IT capacity with the business needs and objectives. Forecasting technology trends is a possible outcome of capacity management, but it is not its main purpose. Establishing the capacity of network communication links is a part of capacity management, but it is not its main goal. Determining business transaction volumes is an input for capacity management, but it is not its main objective.

 The most critical finding for an IS auditor following up on a recent security incident is that the security weakness facilitating the attack was not identified. This finding indicates that the root cause of the incident was not analyzed, and the vulnerability that allowed the attack to succeed was not remediated. This means that the organization is still exposed to the same or similar attacks in the future, and its security posture has not improved. Identifying and addressing the security weakness is a key step in the incident response process, as it helps to prevent recurrence, mitigate impact, and improve resilience.

The other findings are not as critical as the failure to identify the security weakness, but they are still important issues that should be addressed by the organization. The attack was not automatically blocked by the intrusion detection system (IDS) is a finding that suggests that the IDS was not configured properly, or that it did not have the latest signatures or rules to detect and prevent the attack. The attack could not be traced back to the originating person is a finding that implies that the organization did not have sufficient logging, monitoring, or forensic capabilities to identify and attribute the attacker. Appropriate response documentation was not maintained is a finding that indicates that the organization did not follow a consistent and formal incident response procedure, or that it did not document its actions, decisions, and lessons learned from the incident.

 The primary benefit of information asset classification is that it enables risk management decisions. Information asset classification helps to identify the value, sensitivity and criticality of information assets, and to determine the appropriate level of protection and controls required for them. This facilitates risk assessment and risk treatment processes, and ensures that information assets are aligned with business objectives and regulatory requirements. Preventing loss of assets, helping to align organizational objectives or facilitating budgeting accuracy are secondary benefits of information asset classification, but not the main purpose. References: ISACA, CISA Review Manual, 27th Edition, 2018, page 300

The auditor implemented a specific control during the development of the system. This would impair the auditor’s independence, as it would create a self-review threat, which is a situation where an auditor has to evaluate or review the results of his or her own work or judgment1. A self-review threat may compromise the auditor’s objectivity and impartiality, as the auditor may be biased or influenced by his or her own involvement or interest in the system1. The auditor may also face a conflict of interest or a loss of credibility if he or she has to report on any issues or deficiencies related to the control he or she implemented.

Before selecting a SaaS vendor, the most important action is to complete a risk assessment. A risk assessment is a process of identifying, analyzing, and evaluating the potential risks associated with outsourcing software and IT infrastructure to a third-party provider. A risk assessment helps to determine the impact and likelihood of various threats, such as data breaches, service disruptions, vendor lock-in, compliance issues, and legal disputes. A risk assessment also helps to identify the mitigation strategies and controls that can reduce or eliminate the risks.

A risk assessment is more important than determining service level requirements, performing a business impact analysis (BIA), or conducting a vendor audit because it provides the basis for these other actions. Service level requirements are the expectations and obligations that define the quality and quantity of service that the vendor must provide to the customer. A BIA is a process of assessing the potential effects of an interruption or disruption of critical business functions or processes due to an incident or disaster. A vendor audit is a process of verifying the vendor’s compliance with the contract terms, service levels, security policies, and best practices.

Service level requirements, BIA, and vendor audit are all important actions for selecting a SaaS vendor, but they depend on the results of the risk assessment. For example, service level requirements should reflect the risk appetite and tolerance of the customer, which are determined by the risk assessment. A BIA should prioritize the recovery of the most critical and vulnerable business functions or processes, which are identified by the risk assessment. A vendor audit should focus on the areas of highest risk and concern, which are highlighted by the risk assessment.

Therefore, an IS auditor should recommend to management that completing a risk assessment is the most important action before selecting a SaaS vendor.

A source code repository is a system that stores and manages the source code of a software project. A source code repository should be designed to provide secure versioning and backup capabilities for existing code, as these are essential features for concurrent development, code quality, and disaster recovery. Versioning allows developers to track, compare, and revert changes to the code over time. Backup ensures that the code is safely stored and can be restored in case of data loss or corruption.

Documenting anomalies in audit workpapers (D) is the best approach because it ensures traceability, supports findings in the audit report, and allows for future reference if similar issues arise. Even if an anomaly is low-risk, proper documentation is a fundamental audit practice.

Other options:

Reprioritizing testing (A) is a valid audit approach but does not address documentation needs.

Updating the audit plan (B) may be necessary but does not replace documentation.

Prompt remediation (C) is an operational concern but is not always the auditor’s primary role.

A data loss prevention (DLP) tool implemented in monitor mode only observes and logs potential data leakage but does not actively prevent it. This leaves the organization vulnerable to data breaches, making it the most critical concern in a pre-implementation review.

Crawlers for Sensitive Data (Option B):While crawlers may pose a performance impact, they are essential for discovering sensitive data.

Deep Packet Inspection (Option C):Though it introduces privacy considerations, it is a standard DLP functionality for inspecting data in transit.

Encryption Key Management (Option D):While important for security, improper management does not immediately prevent DLP functionality.

 The best way to improve the visibility of end-user computing (EUC) applications that support regulatory reporting is to maintain an EUC inventory, as this provides a comprehensive and up-to-date list of all EUC applications, their owners, their locations, their purposes, and their dependencies. An EUC inventory can help identify and manage the risks associated with EUC applications, such as data quality, security, compliance, and continuity. EUC availability controls, EUC access control matrix, and EUC tests of operational effectiveness are important forensuring the reliability and security of EUC applications, but they do not improve the visibility of EUC applications as much as an EUC inventory. References: CISA Review Manual (DigitalVersion), Chapter 3: Information Systems Acquisition, Development and Implementation, Section 3.4: End-user Computing

The role of a document owner when implementing a data classification policy in an organization is to classify documents to correctly reflect the level of sensitivity of information they contain. A document owner is the person who is ultimately responsible for the creation, maintenance, and protection of a document, usually a member of senior management or a business unit1. A data classification policy is a plan that defines how the organization categorizesits data based on its value, risk, and regulatory requirements, and how it handles and secures each data category2.

According to the data classification policy template by Netwrix3, one of the roles and responsibilities of the document owner is to assign data classification labels based on the data’s potential impact level. Data classification labels are tags or markings that indicate the sensitivity level of the data, such as public, internal, confidential, or restricted. The document owner should apply the data classification labels to the documents that contain the data, either manually or automatically, using tools and methods such as metadata, watermarks, headers, footers, or encryption. The document owner should also review and update the data classification labels periodically or whenever there is a change in the data’s sensitivity level.

By classifying documents to correctly reflect the level of sensitivity of information they contain, the document owner can help to ensure that the documents are handled in accordance with the data classification policy. This means that the documents are stored, accessed, shared, transmitted, and disposed of in a secure and appropriate manner, based on the rules and controls defined for each data category. This can also help to prevent data loss, leakage, or breach incidents that may cause harm or damage to the organization or its stakeholders.

Therefore, option A is the correct answer.

The most important part of a feasibility study is the economics1. A cost-benefit analysis of available products is crucial as it helps to understand the economic viability of the project1. It compares the costs of the project with the benefits it is expected to deliver, which is essential for making informed decisions1. Omitting this could lead to investments in hardware that may not provide the expected returns or meet the organization’s needs.

The best answer is C. Local laws and regulations.

ISACA privacy guidance consistently frames data protection policy around compliance with privacy laws, rules, and regulations. ISACA specifically notes that privacy strategies and policies should be reviewed and updated regularly to reflect regulatory changes and ensure compliance. Since data protection obligations are often legally mandated and penalties can be significant, legal and regulatory requirements are the most important consideration when determining review frequency.

Option A. Industry best practices can inform good policy design, but they do not override legal requirements.

Option B. Business objectives matter for alignment, but they are not the strongest driver of review frequency in a privacy context.

Option D. Known international standards can be useful references, but local legal obligations are more binding and more important for determining how often the policy must be revisited.

Therefore, C is the correct answer because compliance with local laws and regulations is the most important driver of how frequently a data protection policy should be reviewed.

Requiring visitors to present identification and pre-approval documents before entering a data center is a preventive control because its purpose is to stop unauthorized access before it occurs. In CISA-style control classification, a preventive control is designed to avoid an incident or reduce the likelihood of an undesirable event. Screening visitors before access is granted is a classic example of prevention.

Option B is correct because the control is applied before access is granted. It is intended to prevent unauthorized individuals from entering the facility. The control does not primarily detect an event after it happens, nor does it correct a problem after occurrence.

Option A is tempting because visitor procedures are often documented in administrative policies, but the question asks for the type of control implemented in this scenario. The specific mechanism described is an entry-screening measure that functions preventively. In exam logic, when asked to choose between functional control types such as preventive, detective, and corrective, the answer should reflect what the control actually does.

Option C is incorrect because a corrective control acts after an incident to restore or remedy conditions. Visitor ID checks do not correct anything after a breach.

Option D is incorrect because a detective control identifies or alerts after or during an event, such as logs, CCTV review, or alarms. Here, the main purpose is to prevent unauthorized access before entry.

So the best answer is B, since requiring ID and pre-approval documents at the entrance is designed to prevent unauthorized physical access to the data center.

 Team member assignments based on individual competencies is the most important factor to meet the IS audit standard for proficiency. Proficiency is the ability to apply knowledge, skills and experience to perform audit tasks effectively and efficiently. The IS audit standard for proficiency requires that IS auditors must possess the knowledge, skills and discipline to perform audit tasks in accordance with applicable standards, guidelines and procedures. Team member assignments based on individual competencies is a way to ensure that each IS auditor is assigned to audit tasks that match their level of proficiency, and that the audit team as a whole has sufficient and appropriate proficiency to conduct the audit. The other options are not as important as option C, as they do not ensure that the IS auditors have the required proficiency to perform audit tasks. Having a globally recognized audit certification is a way to demonstrate proficiency in IS auditing, but it does not guarantee that the IS auditor has the specific knowledge, skills and experience needed for a particular audit task or system. Technical co-sourcing is a way to supplement the proficiency of the IS audit team by hiring external experts or consultants to perform certain audit tasks or functions, but it does not replace the need for internal IS auditors to have adequate proficiency. Having a supervisor review the new auditors’ work is a way to ensure quality and accuracy of the audit work, but it does not ensure that the new auditors have the necessary proficiency to perform audit tasks independently or competently. References: CISA Review Manual (Digital Version) , Chapter 1: Information Systems Auditing Process, Section 1.4: Audit Skills and Competencies.

Ensuring access rules agree with policies is an information systems security officer’s primary responsibility for business process applications. An information systems security officer should verifythat the access controls implemented for the business process applications are consistent with the organization’s security policy and objectives. The other options are not the primary responsibility of an information systems security officer, but rather the tasks of an application owner, a senior management, or a business analyst. References:

 A differential backup scheme is the best option when storage media is limited, as it only backs up the data that has changed since the last full backup. This reduces the amount of storage space required and also simplifies the restoration process, as only the last full backup and the last differential backup are needed. A real-time backup scheme would require continuous replication of data, which would consume a lot of storage space and network bandwidth. A virtual backup scheme would create a snapshot of the data at a point in time, but it would not reduce the storage space required, as it would still need to store the changes made to the data. A full backup scheme would back up all the data every time, which would require the most storage space and also take longer to complete. References: ISACA, CISA Review Manual, 27th Edition, 2018, page 405

After migrating infrastructure to the cloud, it ' s imperative to test the disaster recovery plan (DRP) to ensure its effectiveness in the new environment. Without evidence of DRP testing post-migration, the organization cannot be certain that it can recover and continue operations during a disaster. While updating the DRP and configuring redundancy are essential steps, their effectiveness can only be validated through rigorous testing. Retaining previous infrastructure is less relevant if the cloud environment is properly configured and tested for disaster recovery.

The best answer is C. Insufficient due diligence performed on the vendor.

ISACA guidance on third-party and cloud risk repeatedly emphasizes the need for thorough vendor due diligence before entering or expanding a business relationship. When confidential backups are being migrated to a cloud solution, insufficient due diligence is the greatest concern because it can expose the organization to security, privacy, resilience, and compliance failures across the whole service arrangement.

Option A is relevant for retired media handling, but it is narrower than the overall third-party risk. Option B affects performance and growth, not necessarily confidentiality. Option D is a business issue, but not the greatest audit concern when confidential data is involved. Vendor due diligence is the most important control at this stage.

 Developing the CSA questionnaire is an activity that would allow an IS auditor to maintain independence while facilitating a control self-assessment (CSA). An IS auditor can design and provide a CSA questionnaire to help the business units or process owners to evaluate their own controls and identify any issues or improvement opportunities. This will enable an IS auditor to support and guide the CSA process without compromising their objectivity or independence. The other options are activities that would impair an IS auditor’s independence while facilitating a CSA, as they involve implementing, completing, or developing remediation actions for control issues. References:

The most significant risk that IS auditors are required to consider for each engagement is the misalignment with business objectives. This is because IS audit engagements are intended to provide assurance that the IT systems and processes support the achievement of the business objectives and strategies. If there is a misalignment,it could result in wasted resources, missed opportunities, inefficiencies, errors, or failures that could adversely affect the organization’s performance and reputation12. References: 1: CISA Review Manual (Digital Version), Chapter 1: The Process of Auditing Information Systems, Section 1.3: Audit Risk, page 28 2: CISA Online Review Course, Module 1: The Process of Auditing Information Systems, Lesson 1.3: Audit Risk

Asset life cycle management is a technique of asset management where facility managers maximize the usable life of assets throughplanning, purchasing, using, maintaining, and disposing of assets1. The mainaim of assetlife cycle management is to reduce costs and increase productivity by optimizing the performance, reliability, and lifespan of assets2. Asset life cycle management can help prevent the situation of having unused applications by ensuring that the applications are aligned with the business needs, objectives, and strategies, and that they are regularly reviewed, updated, or retired as necessary3.

The other options are not as effective as asset life cycle management for preventing unused applications. A formal request for proposal (RFP) process is a method of soliciting bids from potential vendors or suppliers for a project or service. A RFP process can help select the best application for a specific requirement, but it does not ensure that the application will be used or maintained throughout its lifecycle. Business case development procedures are a set of steps that involve defining the problem, analyzing the alternatives, and proposing a solution for a project or initiative. Business case development procedures can help justify the need and value of an application, but they do not guarantee that the application will be utilized or supported after its implementation. An information asset acquisition policy is a document that outlines the rules and standards for acquiring information assets such as applications. An information asset acquisition policy can help ensure that the applications are acquired in a consistent and compliant manner, but it does not address how the applications will be managed or disposed of after their acquisition.

The most critical factor for the success of an information security program is management’s commitment to information security. Management’s commitment to information security means that the senior management supports, sponsors, funds, monitors and enforces the information security program within the organization. Management’s commitment to information security also demonstrates leadership, sets the tone and culture, and establishes the strategic direction and objectives for information security. User accountability for information security, alignment of information security with IT objectives, and integration of business and information security are also important factors for the success of an information security program, but they are not as critical as management’s commitment to information security, as they depend on or derive from it. References: Info Technology and Systems Resources | COBIT, Risk, Governance … - ISACA, IT Governance and Process Maturity

Mirroring (Option B) is the best choice for applications requiring a short Recovery Point Objective (RPO) because it provides real-time replication of data, ensuring minimal data loss.

ISACA CISA Reference: Data replication strategies in disaster recovery planning emphasize mirroring for high-availability systems.

Risk Implication: If mirroring is not implemented for critical systems, significant data loss may occur in the event of a failure.

Alternative Choices:

Option A: Snapshots capture data at specific points in time, leading to potential data loss.

Option C: Log shipping has delays due to batch processing.

Option D: Backups are periodic and not suitable for short RPO needs.

Processes to recover critical files after a ransomware attack are corrective controls because they are designed to restore systems or data after an incident has occurred. ISACA guidance on ransomware and security controls explicitly identifies backups and recovery capabilities as corrective in nature.

Option D is correct because corrective controls aim to reduce the impact of an event and restore normal operations. File recovery, restoration from backups, and recovery procedures are classic corrective activities. ISACA specifically notes that restoring from backups is an effective corrective action against ransomware.

Option B is incorrect because preventive controls try to stop the ransomware attack from happening in the first place, such as patching, endpoint protection, email filtering, or access controls. Recovery processes occur after the attack and therefore are not preventive.

Option C is incorrect because detective controls identify that an incident has occurred or is occurring, such as alerts, monitoring, or anomaly detection. Recovery processes do not detect; they restore.

Option A is incorrect because compensating controls are alternate controls used when a primary control cannot be implemented as intended. Recovery processes after ransomware are more directly classified as corrective, not compensating.

Therefore, D is the best answer because processes for recovering critical files after ransomware are designed to correct the damage and restore operations.

Requirements analysis should be the best thing to compare against the business case when determining whether a project in the design phase will meet organizational objectives, because it defines the functional and non-functional specifications of the project deliverables that should satisfy the business needs and expectations. Requirements analysis can help evaluate whether the project design is aligned with the business case and whether it can achieve the desired outcomes and benefits. Implementation plan, project budget provisions, and project plan are also important aspects of a project in the design phase, but they are not as relevant asrequirements analysisfor comparing against the business case. References: CISA Review Manual (Digital Version), Chapter 4, Section 4.2.1

The best source of information for IT management to estimate resource requirements for future projects is the records of actual time spent on projects. This data can provide a realistic and reliable basis for forecasting future resource needs based on historical trends and patterns. The records of actual time spent on projects can also help IT management to identify any gaps or inefficiencies in resource allocation and utilization. The human resources (HR) sourcing strategy is not a good source of information for estimating resource requirements for future projects, as it may not reflect the actual demand and availability of IT resources. The peer organization staffing benchmarks are not a good source of information for estimating resource requirements for future projects, as they may not account for the specific characteristics and needs of each organization. The budgeted forecast for the next financial year is not a good source of information for estimating resource requirements for future projects, as it may not be based on accurate or realistic assumptions. References:

Anti-malware tool audit logs would provide an IS auditor with the best evidence of continuous compliance with the global organization’s policy that states that all workstations must be scanned for malware each day. Anti-malware tool audit logs are records that capture the activities and events related to the anti-malware software installed on the workstations, such as scan schedules, scan results, updates, alerts, and actions taken1. These logs can help the IS auditor to verify that the anti-malware software is functioning properly, that the scans are performed regularly and effectively, and that any malware incidents are detected and resolved in a timely manner2. Anti-malware tool audit logs can also help the IS auditor to identify any gaps or weaknesses in the anti-malware policy or implementation, and to provide recommendations for improvement3.

The other options are not the best evidence of continuous compliance with the anti-malware policy. Penetration testing results are reports that show the vulnerabilities and risks of the workstations and network from an external or internal attacker’s perspective4. While penetration testing can help to assess the security posture and resilience of the organization, it does not provide information on the daily anti-malware scans or their outcomes. Management attestation is a statement or declaration from the management that they have complied with the anti-malware policy5. While management attestation can demonstrate commitment and accountability, it does not provide objective or verifiable evidence of compliance. Recent malware scan reports are documents that show the summary or details of the latest anti-malware scans performed on the workstations. While recent malware scan reports can indicate the current status and performance of the anti-malware software, they do not provide historical or comprehensive evidence of compliance.

The primary responsibility of an IS auditor during the design phase of a software development project is to evaluate the controls incorporated into the system specifications. Controls aremechanisms or procedures that aim to ensure the security, reliability, or performance of a system or process. System specifications are documents that define and describe the requirements, features, functions, or components of a system or software. Evaluating the controls incorporated into the system specifications is a key responsibility of an IS auditor during the design phase of a software development project, as it helps ensure that the system or software meets the organization’s objectives, standards, and expectations for security, reliability, or performance. The other options are not primary responsibilities of an IS auditor during the design phase of a software development project, as they do not directly relate to evaluating the controls incorporated into the system specifications. Future compatibility of the application is a possible factor that may affect the functionality or usability of the application in different environments or platforms, but it is not a primary responsibility of an IS auditor during the design phase of a software development project. Proposed functionality of the application is a possible factor that may affect the suitability or value of the application for meeting user needs or expectations, but it is not a primary responsibility of an IS auditor during the design phase of a software development project. Development methodology employed is a possible factor that may affect the quality or consistency of the software development process, but it is not a primary responsibility of an IS auditor during the design phase of a software development project. References: CISA Review Manual (Digital Version), Chapter 3, Section 3.3

Zero Trustis based on the principle of " never trust, always verify, " makingidentity validationthe most critical aspect.

Option A (Incorrect):Firmware updatesare important for security but are onlyone partof aZero Trustapproach.

Option B (Correct):Device and user identity validationensures that onlyauthorizedentities can accesscritical resources, reducing the risk of unauthorized access.

Option C (Incorrect):User awarenessis important but does not enforce access control, which isfundamentalto Zero Trust.

Option D (Incorrect):Encryptionsecures data but does not controlwho can access resources, which is the primary focus of Zero Trust.

The business owner is the person or entity that has the authority and responsibility for defining the purpose and scope of the processing of personal data, as well as the expected outcomes and benefits. The business owner is also accountable for ensuring that the processing of personal data complies with the applicable laws and regulations, such as the General Data Protection Regulation (GDPR) or the Data Protection Act 2018 (DPA 2018).

One of the requirements of the GDPR and the DPA 2018 is to adhere to the principle of storage limitation, which states that personal data should be kept for no longer than is necessary for the purposes for which it is processed1. This means that the business owner should determine and justify how long they need to retain personal data, based on factors such as:

The nature and sensitivity of the personal data

The legal or contractual obligations or rights that apply to the personal data

The business or operational needs and expectations that depend on the personal data

The risks and impacts that may arise from retaining or deleting the personal data

The business owner should also establish and document the conditions and methods for the destruction of personal data, such as:

The criteria and triggers for deciding when to destroy personal data

The procedures and tools for securely erasing or anonymising personal data

The roles and responsibilities for carrying out and overseeing the destruction of personal data

The records and reports for verifying and evidencing the destruction of personal data

Therefore, retention periods and conditions for the destruction of personal data should be determined by the business owner, as they are in charge of defining and managing the processing of personal data, as well as ensuring its compliance with the law.

During the second year of the ERP system upgrade project, the focus shifts to ensuring that the updated business processes integrate seamlessly with the new system functionality. User acceptance testing (UAT) validates that the system meets user requirements and business objectives.

Data Migration (Option A):Data migration is more relevant in the first phase when upgrading the system version.

Sociability Testing (Option B):This is less critical than confirming user functionality for process changes.

Initial User Access Provisioning (Option D):This is part of security and access controls but not the primary focus of business process validation.

The greatest concern for an IS auditor reviewing an online security awareness program is that metrics have not been established to assess training results. Without metrics, it is difficult to measure the effectiveness of the program and identify areas for improvement. The other findings are alsoissues that need to be addressed, but they are not as significant as the lack of metrics. References: CISA Review Manual (Digital Version), Chapter 5, Section 5.3.11

Comprehensive and Detailed Explanation:

In Zero Trust architecture (ZTA), the principle is “never trust, always verify.” The most important aspect for an IS auditor to evaluate is whether access control policies are properly designed, aligned with industry standards, and consistently enforced. These policies define how identities, devices, and contexts are authenticated and authorized before gaining access.

Option A: Perimeter firewalls are less relevant in Zero Trust, which minimizes reliance on network boundaries.

Option C: Access reviews are important but are periodic, not continuous enforcement.

Option D: Secure remote protocols are necessary but part of broader access policy enforcement.

Option B: Correct — policies are the foundation of Zero Trust security.

A benefits realization process is a systematic way of identifying, defining, planning, tracking and realizing the benefits from a project or program. Benefits are the measurable improvements that result from the delivery of project outputs and outcomes. Benefits realization management (BRM) is the practice of ensuring that benefits are derived from outputs and outcomes.

One of the best practices for BRM is to select metrics for the project before it begins. Metrics are the indicators that measure the performance and value of the project and its benefits. By selecting metrics in advance, the project team can align the project objectives with the expected benefits, establish a baseline for comparison, and monitor and evaluate the progress and results of the project. Metrics also help to communicate the value of the project to stakeholders and justify the investment.

The other options are not as effective as selecting metrics before the project begins. Project budget is an important factor for BRM, but it does not enable the benefits realization process by itself. It only reflects the costs of executing the project and delivering the solution, not the benefits or value that are expected from them. Estimates of business benefits are useful for planning and forecasting, but they are not sufficient for BRM. They need to be validated by actual data and evidence from similar projects or other sources. Metrics are evaluated after the project has been implemented, but this is only one part of the benefits realization process. BRM requires continuous monitoring and evaluation throughout the project life cycle and beyond, to ensure that benefits are sustained and optimized.

A biometric access device installed at the entrance to a facility is a type of preventive control. Preventive controls are designed to deter or prevent undesirable events from occurring12. They are proactive measures that aim to inhibit incidents before they happen12. In this case, the biometric access device prevents unauthorized individuals from gaining access to the facility by requiring unique biological characteristics for authentication12.

The best answer is D.

ISACA guidance on shadow AI and emerging technology risk highlights data breaches, privacy risk, and data leakage as major concerns when employees use unapproved public AI tools. Public cloud AI use can expose sensitive data through prompts, uploads, or output handling, making data leakage the greatest immediate concern from an audit and control perspective.

Option A is a concern because AI outputs can be inaccurate, but poor reliability usually does not create the same immediate confidentiality exposure as leaking internal data. Option B is less severe. Option C can matter in some use cases, but the most significant enterprise risk identified in ISACA’s public guidance is unauthorized disclosure of data.

The greatest concern for an IS auditor when reviewing IT policies and procedures that are not regularly reviewed and updated is that policies and procedures might not reflect current practices. Policies are documents that define the goals, objectives, and guidelines for an organization’s information systems and resources. Procedures are documents that describe the steps, tasks, or activities for implementing or executing policies. Policies and procedures should be regularly reviewed and updated to ensure that they are relevant, accurate, consistent, and effective for the organization’s information systems and resources. Policies and procedures that are not regularly reviewed and updated might not reflect current practices, as they might be outdated, obsolete, or incompatible with the current state or needs of the organization’s information systems and resources. This can cause confusion, inconsistency, inefficiency, or noncompliance among users or stakeholders who rely on policies and procedures for guidance or direction. Policies and procedures might not include new systems and corresponding process changes is a possible concern for an IS auditor when reviewing IT policies and procedures that are not regularly reviewed and updated, but it is not the greatest one. Policies and procedures might not include new systems and corresponding process changes, as they might be unaware of or unresponsive to the introduction or modification of information systems or resources within the organization. This can cause gaps, overlaps, or conflicts among policies and procedures that affect different information systems or resources. 

 A weakness in change management is the most likely cause of an incorrect version of source code being amended by a development team. Change management is the process of controlling and documenting changes to IT systems and software. It ensures that changes are authorized, tested, and implemented in a controlled manner. If change management is weak, there is a risk of using outdated or incorrect versions of source code, which can lead to errors, defects, or security vulnerabilities in the software.

A firewall log is a record of the traffic and events that occur at the firewall, which is a device or software that controls and filters the incoming and outgoing network traffic based on predefined rules and policies. The integrity of a firewall log means that the log is accurate, complete, consistent, and valid, and that it has not been altered, deleted, or corrupted by unauthorized or malicious parties. The IS auditor should verify that the firewall log has adequate controls to prevent or detect any modification of the log, such as encryption, hashing, digital signatures, write-once media, or tamper-evident seals. The other options are not as effective as ensuring that the log cannot be modified, because they either do not address the integrity of the log data, or they are monitoring or retention measures rather than preventive or detective controls. References: CISA Review Manual (Digital Version)1, Chapter 5, Section 5.2.4

The business owner is best positioned to catalog and inventory robotic process automation (RPA) processes because they understand the processes, objectives, and associated risks. They ensure that RPA aligns with business goals and compliance requirements.

IT Personnel (Option A):Typically support implementation and maintenance but may lack insight into business processes.

Information Security Personnel (Option C):Focus on securing processes but are not responsible for inventorying them.

Data Steward (Option D):Primarily responsible for data governance, not RPA process inventory.

The answer D is correct because the best way for the auditor to confirm the change log is complete is to take the last change from the system and trace it back to the log. A change log is a record of all the changes that have been made to a system, such as software updates, bug fixes, configuration modifications, etc. A change log should contain information such as the date and time of the change, the description and purpose of the change, the person or service who made the change, and the approval status of the change. A complete change log helps to ensure that the system is secure, reliable, and compliant with the relevant standards and regulations.

An IS auditor evaluating the change management process must select a sample from the change log to verify that the changes are properly authorized, documented, tested, and implemented. However, before selecting a sample, the auditor must ensure that the change log is complete and accurate, meaning that it contains all the changes that have been made to the system and that there are no missing, duplicated, or falsified entries. To do this, the auditor can use a technique called backward tracing, which involves taking the last change from the system and tracing it back to the log. This way, the auditor can check if the change is recorded in the log with all the relevant details and if there are any gaps or inconsistencies in the log. If the last change from the system is not found in the log or does not match with the log entry, it indicates that the change log is incomplete or inaccurate.

The other options are not as good as option D. Interviewing change management personnel about completeness (option A) is not a reliable way to confirm the change log is complete because it relies on subjective opinions and self-reported information, which may not be truthful or accurate. Taking an item from the log and tracing it back to the system (option B) is a technique called forward tracing, which can be used to verify that a specific change in the log has been implemented in the system. However, this technique does not confirm that all changes in the system are recorded in the log. Obtaining management attestation of completeness (option C) is not a sufficient way to confirm the change log is complete because it does not provide any evidence or verification of completeness. Management attestation may also be biased or influenced by conflicts of interest.

The most important action before the audit work begins is to establish control objectives. Control objectives are the specific goals or outcomes that the audit intends to achieve or verify in relation to the information protection in the application1. Control objectives provide the basis for designing and performing the audit procedures, evaluating the audit evidence, and reporting the audit findings and recommendations2. Control objectives also help to align the audit scope and criteria with the business needs and expectations, and to ensure that the audit is relevant, reliable, and efficient3.

Some examples of control objectives for an information protection audit are:

To ensure that the information stored in the application is classified according to its sensitivity, value, and regulatory requirements

To ensure that the information stored in the application is encrypted, masked, or anonymized as appropriate

To ensure that the information stored in the application is accessible only by authorized users and processes

To ensure that the information stored in the application is backed up, restored, and retained according to the business continuity and retention policies

To ensure that the information stored in the application is monitored, logged, and audited for any unauthorized or anomalous activities

Therefore, option B is the correct answer.

Option A is not correct because reviewing remediation reports is not the most important action before the audit work begins. Remediation reports are documents that describe how previous audit findings or issues have been resolved or addressed by the auditee4. While reviewing remediation reports may be useful for understanding the current state of information protection in the application, it is not a prerequisite for defining the control objectives of the audit.

Option C is not correct because assessing the threat landscape is not the most important action before the audit work begins. The threat landscape is the set of potential sources, methods, and impacts of cyberattacks or data breaches that may affect the information stored in the application5. While assessing the threat landscape may be helpful for identifying and prioritizing the risks and vulnerabilities of information protection in the application, it is not a prerequisite for defining the control objectives of the audit.

Option D is not correct because performing penetration testing is not the most important action before the audit work begins. Penetration testing is a technique that simulates real-world cyberattacks or data breaches to test the security and resilience of information systems or applications. 

 The best recommendation to address the situation of inconsistencies in privacy requirements across third-party service provider contracts is to prioritize contract amendments for third-party providers. This is because:

Privacy requirements are essential to ensure the protection of personal information and compliance with relevant laws and regulations, such as the GDPR and the CCPA123.

Inconsistencies in privacy requirements can create risks of data breaches, legal liabilities, reputational damage, and consumer distrust for the organization that outsources its data processing to third-party providers123.

Suspending contracts with third-party providers that handle sensitive data (option A) is not a feasible or effective solution, as it may disrupt the business operations and cause contractual penalties or disputes4.

Reviewing privacy requirements when contracts come up for renewal (option C) is not a proactive or timely approach, as it may leave the organization exposed to privacy risks for a long period of time until the contracts expire4.

Requiring third-party providers to sign nondisclosure agreements (NDAs) (option D) is not a sufficient measure, as NDAs only cover the confidentiality of information, but not other aspects of privacy, such as data minimization, retention, access, deletion, and security4.

Therefore, the best recommendation is to prioritize contract amendments for third-party providers (option B), as this would allow the organization to align the privacy requirements with its own policies and standards, as well as with the applicable laws and regulations. This would also enable the organization to monitor and audit the compliance of third-party providers with the privacy requirements and enforce appropriate remedies or sanctions in case of noncompliance45.

The most important responsibility of data owners when implementing a data classification process is determining appropriate user access levels (option C). This is because:

Data owners are the persons or entities that have the authority and responsibility for the business processes and functions that collect, use, store, and dispose of data1.

Data owners are accountable for ensuring that the data is handled in compliance with the applicable laws, regulations, policies, and standards, such as the GDPR and the PIPEDA1234.

Data owners are in the best position to determine the purpose and necessity of collecting and retaining data, as well as the risks and benefits associated with it1.

Data owners should consult with other stakeholders, such as the risk manager, the database administrator (DBA), and the privacy manager, to establish and implement appropriate data classification policies and procedures2.

Data classification is the process of organizing data in groups based on their attributes and characteristics, and then assigning class labels that describe a set of attributes that hold true for the corresponding data sets345.

Data classification helps organizations to identify, manage, protect, and understand their data, as well as to comply with modern data privacy regulations345.

Data classification also helps to determine appropriate user access levels, which means defining who can access, modify, share, or delete data based on their roles, responsibilities, and needs345.

Determining appropriate user access levels is the most important responsibility of data owners when implementing a data classification process, as it ensures that only authorized and legitimate users can access sensitive or important data. This provides confidentiality, integrity, availability, and accountability of data345.

Reviewing emergency changes to data (option A), authorizing application code changes (option B), and implementing access rules over database tables (option D) are not the most important responsibilities of data owners when implementing a data classification process. These are more related to the operational aspects of data management, which are usually delegated to other roles, such as the DBA or the IT staff. The data owner should oversee and approve these activities, but not perform them directly1.

The most important aspect of an incident response management program is the ability to detect incidents in a timely and accurate manner. Without effective detection, the organization cannot respond to incidents, mitigate their impact, or prevent their recurrence. The alerting tools and incident responseteam are responsible for monitoring the IT environment, identifying anomalies or threats, and notifying the appropriate stakeholders.

Outsourcing the audit to independent and qualified resources is the best course of action for the IS audit manager who was temporarily tasked with supervising a project manager assigned to the organization’s payroll application upgrade. This is because the IS audit manager has a potential conflict of interest and a threat to objectivity and independence, which are essential principles and standards for IS auditors.

According to the ISACA Code of Professional Ethics, IS auditors should maintain objectivity and independence in their professional judgment and avoid any situations that may impair or be presumed to impair their objectivity or independence1. Objectivity is the mental attitude of an IS auditor that allows them to perform their work honestly, impartially, and with integrity, while independence is the freedom from conditions that threaten the ability of an IS auditor to carry out their work in an unbiased manner2.

The IS audit manager who was involved in supervising the payroll application upgrade project may have a self-review threat, which is the risk that an IS auditor will not appropriately evaluate the results of a previous judgment made or service performed by them or their subordinates3. The IS audit manager may also have a familiarity threat, which is the risk that an IS auditor will be influenced by a close relationship with someone involved in the project or by their own personal interests4. These threats may compromise the IS audit manager’s objectivity and independence and affect the quality and credibility of the audit.

Therefore, the IS audit manager should disclose their involvement in the project to their senior management and the audit committee and decline to perform or manage the audit. The IS audit manager should also recommend outsourcing the audit to independent and qualified resources who have no connection or interest in the project and who have the necessary skills and experience to conduct a reliable and effective audit.

The other options are not the best course of action for the IS audit manager.

Transferring the assignment to a different audit manager despite lack of IT project management experience is not the best course of action because it may result in a low-quality audit that does not meet the expectations and standards of the stakeholders. IT project management experience is essential for auditing an IT project, as it requires knowledge of project management methodologies, tools, techniques, risks, and best practices. An audit manager who lacks IT project management experience may not be able to plan, execute, report, and follow up on the audit effectively and efficiently.

Managing the audit since there is no one else with the appropriate experience is not the best course of action because it violates the ethical principles and standards of objectivity and independence for IS auditors. Managing the audit would create a conflict of interest and a threat to objectivity and independence for the IS audit manager, as they would be reviewing their own work or that of their subordinate. Managing the audit would also undermine the credibility and reliability of the audit results and recommendations, as they may be biased or influenced by personal or professional relationships or interests.

Having a senior IS auditor manage the project with the IS audit manager performing final review is not the best course of action because it still involves the IS audit manager in the audit process, which poses a conflict of interest and a threat to objectivity and independence. Performing final review would require the IS audit manager to evaluate and approve the work done by the senior IS auditor, which may be affected by their previous involvement in or knowledge of the project. Performing final review would also expose theIS audit manager to undue pressure or influence from management or other stakeholders who may have expectations or preferences regarding the audit outcome.

 Social engineering is the manipulation of people to perform actions or divulge confidential information. It is a common technique used by attackers to gain unauthorized access to systems or data. Employees who use public social networking sites may be vulnerable to social engineering attacks, such as phishing, baiting, or pretexting, which pose the greatest risk to the organization’s security. The other options are not as serious as social engineering, as they relate to web application vulnerabilities, intellectual property rights, and reputation management, which are less likely to compromise the organization’s assets or operations. References: CISA Review Manual (Digital Version), Domain 5: Protection of Information Assets, Section 5.3 Security Awareness Training1

 The auditor should be most concerned with the impact AI will have on enterprise architecture (EA) when reviewing a project to replace multiple manual data entry systems with an AI system. EA is a comprehensive framework that defines the structure, components, relationships, and principles of an organization’s IT environment. EA can help to align the IT strategy with the business strategy and ensure the coherence, consistency, and integration of the IT systems and services. Replacing manual data entry systems with an AI system may have significant implications for the EA, such aschanging the business processes, data flows, security requirements, performance standards, or governance models. The auditor should assess whether the project has considered the impact of AI on EA and whether the EA has been updated accordingly. References:

The best answer is B. Residual risk.

ISACA defines residual risk as the amount of risk remaining after controls and mitigation efforts are put in place. Because risk management strategies are implemented to mitigate risk, the type of risk most directly reduced is residual risk. Inherent risk exists before controls are applied, so it is not the risk category most directly reduced by control implementation. Sampling risk and detection risk are audit risks, not the primary target of enterprise risk treatment strategies.

Option C is incorrect because inherent risk is the baseline level of risk absent controls. Option A and D relate to audit methodology and audit assurance rather than enterprise risk treatment outcomes. ISACA’s risk guidance consistently describes controls and mitigation efforts as mechanisms to reduce remaining exposure to an acceptable level, which is residual risk.

The best course of action for a security administrator who is called in the middle of the night by the on-call programmer who needs access to the live system is to give the programmer an emergency ID for temporary access and review the activity. This is because:

Requiring that a change request be completed and approved may delay the resolution of the problem and cause further damage or disruption to the system or business operations. A change request is a formal document that describes the proposed change, its rationale, impact, benefits, risks, costs, and approval process. A change request is usually required for planned or scheduled changes, not for emergency or urgent changes.

Giving the programmer read-only access to investigate the problem may not be sufficient or effective, as the programmer may need to perform actions or tests that require write or execute permissions. Read-only access means that the user can only view or copy data or files, but cannot modify or delete them.

Reviewing activity logs the following day and investigating any suspicious activity may not prevent or detect any unauthorized or malicious actions by the programmer in real time. Activity logs are records of events and actions that occur within a system or network. Activity logs can provide evidence and accountability for system activities, but they are not proactive or preventive controls.

Therefore, giving the programmer an emergency ID for temporary access and reviewing the activity is the best course of action, as it allows the programmer to access the live system and resolve the problem quickly, while also ensuring that the security administrator can monitor and verify the programmer’s activity and revoke the access when it is no longer needed. An emergency ID is a temporary account that grants a user elevated privileges or access to a system or resource for a specific purpose and duration. An emergency ID should be:

Created and authorized by a security administrator or manager

Assigned to a specific user and purpose

Limited in scope and time

Logged and audited

Revoked and deleted after use

Some of the best practices for emergency access to live systems are12:

Establish clear policies and procedures for requesting, approving, granting, monitoring, reviewing, and revoking emergency access

Define criteria and scenarios for emergency access, such as severity, impact, urgency, and risk

Implement controls to prevent unauthorized or unnecessary use of emergency access, such as multifactor authentication, approval workflows, alerts, notifications, and time restrictions

Implement controls to track and audit emergency access activities, such as logging, reporting, analysis, and investigation

Implement controls to ensure accountability and responsibility for emergency access users, such as attestation, justification, documentation, and feedback

 Limiting the use of logs to only those purposes for which they were collected is the best way to address potential data privacy concerns associated with inadvertent disclosure of machine identifier information contained within security logs, because it minimizes the risk of unauthorized access, misuse, or leakage of personal data that may be embedded in the logs. Logs should be collected and processed in accordance with the data protection principles and regulations, such as theGeneral Data Protection Regulation (GDPR)12. Restricting the transfer of log files from host machine to online storage, only collecting logs from servers classified as business critical, and limiting log collection toonly periods of increased security activity are not effective ways to address data privacy concerns, because they do not prevent or mitigate the potential disclosure of personal datain the logs. References: 1: CISA Review Manual (DigitalVersion), Chapter 5, Section 5.4.4 2: CISA Online Review Course, Module 5, Lesson 4

 Data leakage prevention (DLP) is the process of preventing unauthorized access, disclosure, or transfer of sensitive data. In a multi-tenant cloud environment, where multiple customers share the same infrastructure and resources, DLP is a critical challenge. One of the best methods to enforce DLP in such an environment is to require tenants to implement data classification policies. Data classification policies define the types and levels of sensitivity of data, and the corresponding security controls and measures to protect them. By implementing data classification policies, tenants can ensure that their data is properly labeled, encrypted, segregated, and monitored according to their specific requirements and compliance standards. This can help prevent data leakage from accidental or malicious actions by other tenants, cloud service providers, or external parties.

The IS auditor’s most important course of action after finding that several similar incidents were logged during the audit period is to determine if a root cause analysis was conducted. A root cause analysis is a systematic process that identifies the underlying causes of system failures or incidents. A root cause analysis can help to prevent recurrence of similar incidents, improve system performance and reliability, and enhance incident management processes. The IS auditor should evaluate whether a root cause analysis was performed for each incident, whether it was timely and thorough, and whether it resulted in effective corrective actions.

The most effective way for controlling visitor access to a data center is to ensure that visitors are escorted by an authorized employee, as this prevents unauthorized or malicious actions by the visitors and provides accountability and supervision. Pre-approval of entry requests, visitors signingin at the front desk upon arrival, and closed-circuit television (CCTV) are also useful measures, but they are not as effective as escorting visitors, as theydo not prevent or detect unauthorized or malicious actions by the visitors in real time. References: CISA Review Manual (Digital Version), Chapter 5: Protection of Information Assets, Section 5.1: Physical Access Controls1

Due professional care is the obligation of an IS auditor to exercise the appropriate level of skill, competence, and diligence in performing an audit. It also requires the IS auditor to comply with the relevant standards, guidelines, and ethical principles of the profession. Completing an engagement by email only may compromise due professional care, as it may limit the IS auditor’s ability to obtain sufficient and appropriate evidence, to communicate effectively with the auditee and other stakeholders, and to perform adequate quality assurance and review procedures. The other options are not as relevant as due professional care, as they relate to specific aspects of an audit, such as proficiency (the knowledge and skills of the IS auditor), sufficient evidence (the quantity and quality of the audit evidence), and reporting (the presentation and communication of the audit results). References: CISA Review Manual (Digital Version), Domain 1: The Process of Auditing Information Systems, Section 1.2 ISACA IT Audit and Assurance Standards

 The type of firewall that provides the greatest degree of control against hacker intrusion is an application level gateway. A firewall is a device or software that filters or blocks network traffic based on predefined rules or policies. A firewall can help protect an information system or networkfrom unauthorized access or attack by hackers or other malicious entities. An application level gateway is a type of firewall that operates at the application layer of the network model (layer 7), which is where user applications communicate with each other over the network. An application level gateway provides the greatest degree of control against hacker intrusion, by inspecting and analyzing the content and context of each network packet at the application level, such as protocols, commands, requests, responses, etc., and allowing or denying access based on specific criteria or conditions. An application level gateway can also perform additional functions such as authentication, encryption, caching, logging, etc., to enhance the security and performance of network traffic. A circuit gateway is a type of firewall that operates at the transport layer of the network model (layer 4), which is where data are transferred between end points over the network. A circuit gateway provides a moderate degree of control against hacker intrusion by establishing a secure connection between two end points (such as client and server) and relaying network packets between them without inspecting or analyzing their content. A circuit gateway can also perform functions such as encryption, authentication, or address translation to improve the security and privacy of network traffic. A packet filtering router is a type of firewall that operates at the network layer of the network model (layer 3), which is where data are routed between different networks or subnets. A packet filtering router provides a low degree of control against hacker intrusion by examining the header of each network packet and allowing or denying access based on basic criteria such as source address, destination address, port number, protocol, etc. A packet filtering router can also perform functions such as routing, forwarding, or address translation to optimize the delivery and efficiency of network traffic. A screening router is a type of firewall that operates at the network layer of the network model (layer 3), which is where data are routed between different networks or subnets. A screening router provides a low degree of control against hacker intrusion by examining the header of each network packet and allowing or denying access based on basic criteria such as source address, destination address, port number, protocol, etc. A screening router can also perform functions such as routing, forwarding, or address translation to optimize the delivery and efficiency of network traffic. 

 An IT balanced scorecard is a strategic management tool that aligns IT objectives with business goals and measures the performance of IT processes using key performance indicators (KPIs). It is the most effective means of monitoring governance of enterprise IT, which is the process of ensuring that IT supports the organization’s strategy and objectives. Governance of enterprise IT covers aspects such as IT value delivery, IT risk management, IT resource management, and IT performance measurement. An IT balanced scorecard can help monitor these aspects and provide feedback to improve IT governance. References: ISACA Frameworks: Blueprints for Success, CISA Review Manual (Digital Version)

 The best recommendation to reduce the risk of data leakage from employee use of social networking sites for business purposes is to provide education and guidelines to employees on use of social networking sites. Education and guidelines can help employees understand the benefits and risks of using social media for business purposes, such as enhancing brand awareness, engaging with customers, or sharing industry insights. They can also inform employees about the dos and don’ts of social media etiquette, such as respecting privacy, protecting intellectual property, avoiding conflicts of interest, or complying with legal obligations. Education and guidelines can also raise awareness of potential data leakage scenarios, such as phishing attacks, malicious links, fake profiles, or oversharing sensitive information, and provide tips on how to prevent or respond to them.

For a microservices architecture, the most effective way to understand data movement between components is through data flow diagrams (DFDs). DFDs clearly show inputs, outputs, processes, and data stores, helping auditors trace data movement across distributed services.

Option A: Correct — DFDs highlight application inputs/outputs.

Option B: Network diagrams show infrastructure but not logical data flows.

Option C: Business requirements document functional needs, not technical flows.

Option D: ER diagrams describe database structures, not process flows.

The business case for an information system investment is a document that provides the rationale and justification for the investment, based on the expected costs, benefits, risks, and impacts of the project12. The business case should be available for review until the benefits have been fully realized, because it serves as a baseline for measuring the actual performance and outcomes of the project against the planned ones34. This helps to evaluate the success and value of the investment, and to identify any gaps or issues that need to be addressed5.

 An acceptable use policy (AUP) is a document that defines the rules and guidelines for using an organization’s IT resources, such as networks, devices, and software. It aims to protect the organization’s assets, security, and productivity. An AUP should be formally acknowledged by users to ensure that they are aware of their responsibilities and obligations when using the IT resources. Without formal acknowledgment, users may not be held accountable for violating the AUP or may claim ignorance of the policy. This can expose the organization to legal, regulatory, reputational, or operational risks. Lack of data for measuring compliance, violation of industry standards, and noncompliance with documentation requirements are also possible risks from not having users acknowledge the AUP, but they are less significant than lack of user accountability. References: Workable: Acceptable use policy template, Wikipedia: Acceptable use policy

Comprehensive and Detailed Explanation:

When verifying the integrity of a bit-for-bit copy of digital evidence, hashing algorithms are used. The primary factors in selecting a hashing algorithm are speed and collision resistance.

MD5 (Message Digest 5): While not cryptographically secure for all modern applications due to collision vulnerabilities, it is very fast and still acceptable in forensic integrity verification where speed is critical and the probability of collision is negligible for one-time checks.

SHA-1 / SHA-2: Provide stronger cryptographic assurance but are slower than MD5. They are preferred for long-term integrity assurance but not when processing speed is the top priority.

AES (Advanced Encryption Standard): AES is an encryption algorithm, not a hashing algorithm, and therefore is not appropriate for integrity verification.

The primary purpose of a post-implementation audit or post-implementation review is to determine whether the system implementation achieved what it was supposed to achieve. In CISA terms, this means confirming whether the project deliverables, controls, and requirements were met. ISACA’s CISA exam content explicitly states that a post-implementation review is conducted to determine whether project deliverables, controls, and requirements are met, which directly aligns with option B.

Option A (“Address lessons learned from the project”) is important, but it is secondary, not the most important objective. ISACA material recognizes that lessons learned may be documented as part of a post-implementation review, but this is presented as a useful activity, not the core audit objective. The central audit question remains whether the implementation delivered what was required.

Option C (“Develop a process for continuous improvement”) is also valuable, but that is a broader management and quality-improvement outcome. It is not the main objective of a post-implementation audit. An auditor’s primary focus is assessment and verification, not designing the organization’s continuous improvement process. ISACA’s audit guidance emphasizes that audit objectives are commonly phrased as determining whether something is adequate or achieved, which supports the selection of option B over improvement-oriented options.

Option D (“Seek approval for the next implementation phase”) is not an audit objective. Approval for the next phase is a project governance or management decision, while the audit function is concerned with whether implemented controls, requirements, and deliverables were achieved.

So, the best answer is B, because ISACA ties post-implementation review directly to confirming that the implementation met its required objectives, deliverables, controls, and requirements.

 Ongoing monitoring of the audit activities is the most important activity to include as part of the quality assurance (QA) program requirements for an internal audit department. An IS auditor should perform regular reviews and evaluations of the audit processes, methods, standards, and outcomes to ensure that they comply with the QA program objectives and criteria. This will help to maintain and improve the quality and consistency of the audit services and deliverables. The other options are less important activities to include as part of the QA program requirements, as they may involve long-term resource planning, user satisfaction reports, or feedback from internal audit staff. References:

CISA Review Questions, Answers and Explanations Database, Question ID 224

Data analytics is the process of analyzing large and complex data sets to discover patterns, trends, and insights that can support decision making and problem solving. Data analytics can enable an IS auditor to combine and compare access control lists from various applications and devices by using techniques such as data extraction, transformation, loading, cleansing, integration, aggregation, visualization, and reporting. Data analytics can help an IS auditor to identify and assess the risks and controls related to access management, such as unauthorized or excessive access, segregation of duties violations, access policy compliance, access activity monitoring, and access review and remediation.

The other options are not as effective or relevant as data analytics for combining and comparing access control lists from various applications and devices. Integrated test facility (ITF) is a technique for testing the validity and accuracy of application processing by inserting fictitious transactions into the system and verifying the results. ITF does not directly involve the analysis of access control lists. Snapshots are records of selected information at a specific point in time that can be used to monitor system activity or performance. Snapshots can provide some information about access control lists, but they are not sufficient to combine and compare them across different sources. Audit hooks are software routines embedded in an application that can trigger an alert or a report when certain conditions are met. Audit hooks can help to detect anomalies or exceptions in access control lists, but they do not provide a comprehensive or integrated view of them.

Function point analysis (FPA) is the best methodology to use for estimating the complexity of developing a large business application. FPA is a technique that measures the functionality of a software system based on the user requirements and the business processes that the system supports. FPA assigns a numerical value to each function or feature of the system, based on its type, complexity, and relative size. The total number of function points represents the size and complexity of the system, which can be used to estimate the development effort, cost, and time.

FPA has several advantages over other estimation methods, such as:

It is independent of the technology, programming language, or development methodology used for the system. Therefore, it can be applied consistently across different platforms and environments.

It is based on the user perspective and the business value of the system, rather than the technical details or implementation aspects. Therefore, it can be performed early in the project life cycle, before the design or coding phases.

It is objective and standardized, as it follows a set of rules and guidelines defined by the International Function Point Users Group (IFPUG). Therefore, it can reduce ambiguity and improve accuracy and reliability of the estimates.

It is adaptable and scalable, as it can handle changes in the user requirements or the system scope. Therefore, it can support agile and iterative development approaches.

A key performance indicator (KPI) is a quantifiable measure of performance over time for a specific objective1. KPIs help organizations and teams track their progress and achievements towards their strategic goals. To be useful, a KPI must have a target value, which is the desired level of performance or outcome that the organization or team aims to achieve. A target value provides a clear direction and a benchmark for measuring success or failure. Without a target value, a KPI is meaningless, as it does not indicate whether the performance is good or bad, or how far or close the organization or team is from reaching their objective.

The most helpful tool in matching demand for projects and services with available resources in a way that supports business objectives is portfolio management. Portfolio management is the process of selecting, prioritizing, balancing and aligning IT projects and services with the strategic goals and value proposition of the organization3. Portfolio management helps the IT organization to allocate resources efficiently and effectively, to deliver value to the business units, and to align IT initiatives with business strategies. Project management, risk assessment results and IT governance framework are also important tools, but they are not as helpful as portfolio management in matching demand and supply of IT projects and services. References:
