CISA Certified Information Systems Auditor Questions and Answers

 Periodic review of access profiles by management is an additional control that is required when using swipe cards to limit employee access to restricted areas. Swipe cards are a type of physical access control that use magnetic stripes or radio frequency identification (RFID) to store and transmit information about the cardholder’s identity and access rights. Swipe cards can help to prevent unauthorized entry, protect sensitive assets and data, and monitor access activity. However, swipe cards alone are not enough to ensure effective access control. They need to be complemented by other controls, such as:

Periodic review of access profiles by management: This is a type of logical access control that involves verifying that the access rights assigned to each cardholder are appropriate, necessary, and consistent with the organization’s policies and procedures. Periodic review of access profiles can help to detect and correct any errors, inconsistencies, or violations in the access control system, such as outdated, excessive, or redundant access rights, segregation of duties conflicts, or unauthorized changes. Periodic review of access profiles can also help to ensure compliance with internal and external audit requirements and regulations.

Implementation of additional PIN pads: This is a type of multi-factor authentication (MFA) that requires the cardholder to enter a personal identification number (PIN) in addition to swiping their card. MFA can enhance the security of the access control system by adding another layer of verificationand reducing the risk of lost, stolen, or cloned cards being used by unauthorized persons.

Installation of closed-circuit television (CCTV): This is a type of surveillance system that uses cameras and monitors to record and display the images of the people and activities in the restricted areas. CCTV can deter potential intruders, provide evidence of any security incidents or breaches, and enable real-time monitoring and response by security personnel.

The other options are not as effective or relevant as periodic review of access profiles by management for an additional control when using swipe cards. Physical sign-in of all employees for access to restricted areas is a redundant and inefficient control that can be easily bypassed or manipulated. It also does not provide any assurance or verification of the identity or access rights of the cardholders. 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.

Change management is the process of planning, implementing, monitoring, and evaluating changes to an organization’s information systems and related components. Change management aims to ensure that changes are aligned with the business objectives, minimize risks and disruptions, and maximize benefits and value.

One of the key aspects of change management is measuring its effectiveness, which means assessing whether the changes have achieved the desired outcomes and met the expectations of the stakeholders. There are various indicators that can be used to measure change management effectiveness, such as time, cost, quality, scope, satisfaction, and performance.

Among the four options given, the most appropriate indicator of change management effectiveness is the number of incidents resulting from changes. An incident is an unplanned event or interruption that affects the normal operation or service delivery of an information system. Incidents can be caused by various factors, such as errors, defects, failures, malfunctions, or malicious attacks. Incidents can have negative impacts on the organization, such as loss of data, productivity, reputation, or revenue.

The number of incidents resulting from changes is a direct measure of how well the changes have been planned, implemented, monitored, and evaluated. A high number of incidents indicates that the changes have not been properly tested, verified, communicated, or controlled. A low number of incidents indicates that the changes have been executed smoothly and successfully. Therefore, the number of incidents resulting from changes reflects the quality and effectiveness of the change management process.

The other three options are not as appropriate indicators of change management effectiveness as the number of incidents resulting from changes. The time lag between changes to the configuration and the update of records is a measure of how timely and accurate the configuration management process is. Configuration management is a subset of change management that focuses on identifying, documenting, and controlling the configuration items (CIs) that make up an information system. The time lag between changes and updates of documentation materials is a measure of how well the documentation process is aligned with the change management process. Documentation is an important aspect of change management that provides information and guidance to the stakeholders involved in or affected by the changes. The number of system software changes is a measure of how frequently and extensively the system software is modified or updated. System software changes are a type of change that affects the operating system, middleware, or utilities that support an information system.

While these three indicators are relevant and useful for measuring certain aspects of change management, they do not directly measure the outcomes or impacts of the changes on the organization. They are more related to the inputs or activities of change management than to its outputs or results. Therefore, they are not as appropriate indicators of change management effectiveness as the number of incidents resulting from changes.

 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 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.

 A business impact analysis (BIA) is a process that identifies and evaluates the potential effects or consequences of disruptions or disasters on an organization’s critical business functions or processes. A BIA can help prioritize the recovery of critical functions by assessing their importance and urgency for the organization’s operations, objectives, and stakeholders, and determining their recovery time objectives (RTOs), which are the maximum acceptable time for restoring a functionafter a disruption. A business continuity plan (BCP) testing is a process that verifies and validates the effectiveness and readiness of a BCP, which is a document that outlines the strategies and procedures for ensuring the continuity of critical business functions in the event of a disruption or disaster. A BCP testing does not prioritize the recovery of critical functions, but rather evaluates how well they are recovered according to the BCP. A disaster recovery plan (DRP) testing is a process that verifies and validates the effectiveness and readiness of a DRP, which is a document that outlines the technical and operational steps for restoring the IT systems and infrastructure that support critical business functions in the event of a disruption or disaster. A DRP testing does not prioritize the recovery of critical functions, but rather evaluates how well they are supported by the IT systems and infrastructure according to the DRP. A risk assessment is a process that identifies and analyzes the potential threats and vulnerabilities that could affect an organization’s critical business functions or processes. A risk assessment does not prioritize the recovery of critical functions, but rather estimates their likelihood and impact of being disrupted by various risk scenarios. 

 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. 

The best answer is B.

A quality assurance and improvement program is meant to evaluate whether the audit function is performing effectively and independently. ISACA’s candidate guide explicitly includes evaluating audit processes as part of QA and improvement programs, and ISACA peer-review guidance states that a peer review process assessing internal audit is essential to ensure it is appropriately carrying out its role. The absence of independent periodic external review is therefore the most serious concern because it weakens objective assessment of audit quality itself.

Option A is a weakness, but tracking improvement opportunities centrally is secondary to having independent validation that the function meets expected quality standards. Option C is not the best answer because substantive testing during an assessment phase may vary by engagement design. Option D matters for governance communication, but it is still less central to QA than the lack of external independent review.

 Access to the data center is controlled by a mantrap provides the greatest assurance that only authorized individuals can access a data center. A mantrap is a physical security device that consists of a small space with two sets of interlocking doors, such that the first set of doors must close before the second set opens1. A mantrap prevents unauthorized entry by requiring authentication at both doors, such as biometric scanners, card readers, or PIN codes. A mantrap also prevents tailgating, which is the act of following an authorized person into a restricted area without proper authorization2. A mantrap can also detect and trap intruders who attempt to force their way through the doors.

The other options are less effective physical controls for data center access. The data center is patrolled by a security guard is a deterrent measure, but it does not prevent unauthorized access by itself. A security guard may not be able to monitor all entry points, or may be distracted, bribed, or overpowered by intruders. Access to the data center is monitored by video cameras is a detective measure, but it does not prevent unauthorized access either. Video cameras can record the activities of intruders, but they cannot stop them from entering or alert the security personnel in real time. ID badges must be displayed before access is granted is a preventive measure, but it relies on human verification, which can be prone to errors or manipulation. ID badges can also be lost, stolen, or forged by intruders.

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. 

Disabling USB access for storage devices is a preventive control because it is intended to stop malware introduction before it occurs. ISACA explicitly describes disabling USB access for storage devices as a preventive control that makes it harder for users to introduce threats such as viruses into the environment.

Option C is correct because the control works in advance of the event. It prevents users from connecting removable storage that could carry malicious software or facilitate unauthorized data transfer.

Option A is incorrect because corrective controls act after an incident to restore or remediate conditions. USB blocking does not restore anything after infection.

Option B is not the best answer because although administrative policy may require the control, the specific control being described functionally prevents an unwanted event. In CISA questions, the functional type is the better classification here.

Option D is incorrect because the control is not physical; it is a logical/technical measure enforced through system configuration.

Therefore, C is the best answer because disabling USB storage access is designed to prevent malware from being introduced through physical media.

The effectiveness of a security awareness training program is best indicated by a reduction in unintentional violations. When employees are well-trained and aware of security practices, they are less likely to inadvertently violate security policies or make mistakes that could lead to breaches. While other factors (such as third-party social engineering tests, employee satisfaction, and completion rates) provide valuable insights, the ultimate goal of security awareness training is to minimize unintentional errors and improve overall security posture12. References: 1(https://www.isaca.org/resources/isaca-journal/issues/2023/volume-2/considerations-for-developing-cybersecurity-awareness-training) 2(https://www.isaca.org/resources/news-and-trends/isaca-now-blog/2023/security-awareness-training-a-critical-success-factor-for-organizations)

The best assurance that a new DBMS meets local privacy regulations is provided by a compliance audit. ISACA defines privacy compliance as adherence to relevant data protection laws, regulations, standards, and policies. A compliance-focused review is therefore the most direct way to determine whether the DBMS design, configuration, and operation satisfy applicable privacy requirements.

Option A is correct because the question is specifically about meeting local privacy regulations. A compliance audit is designed to assess conformance with external legal and regulatory obligations as well as applicable internal requirements. ISACA’s privacy risk guidance also notes that privacy assessments determine whether an enterprise is in compliance with applicable laws and regulations.

Option B is incorrect because an administrative audit is broader and does not specifically target legal and regulatory privacy compliance.

Option C is incorrect because a general IT controls review may assess access, change management, backup, and operations controls, but it does not directly assure compliance with privacy laws.

Option D is incorrect because a forensic audit is typically used to investigate incidents or evidence after suspected wrongdoing, not to assess upfront regulatory compliance. ISACA’s digital forensics guidance is centered on identifying, preserving, analyzing, and presenting evidence.

Therefore, A is the best answer because a compliance audit most directly evaluates whether the DBMS meets local privacy regulatory requirements.

 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

For online payment security, bothconfidentiality(protection of data) andnonrepudiation(ensuring the sender cannot deny a transaction) are essential.

Option A (Incorrect):DES is outdatedandinsecurefor modern encryption needs. It has been replaced by stronger algorithms.

Option B (Incorrect):AES provides strong encryption(confidentiality) but does not handlenonrepudiationon its own.

Option C (Correct):PKI (Public Key Infrastructure)is the best solution because it providesencryption for confidentialityanddigital signatures for nonrepudiation, ensuring bothsecuretransactions andauthenticationof parties involved.

Option D (Incorrect):AVPN secures network traffic, but it does not address nonrepudiation, which is critical in online payments.

 Secure coding practices are the best way to prevent cross-site scripting (XSS) attacks, because they can ensure that the web application validates and sanitizes user input and output data to prevent malicious scripts from being executed on the web browser. XSS attacks are a type of web application vulnerability that exploit the lack of input validation or output encoding in webpages that accept user input or display dynamic content. Application firewall policy settings, a three-tier web architecture, and use of common industry frameworks are not effective controlsto prevent XSS attacks, because they do not address the root cause of the vulnerability in the web application code. References: CISA Review Manual (Digital Version), Chapter 5, Section 5.4.2

 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 best reason to implement a data retention policy is to limit the liability associated with storing and protecting information. A data retention policy is a business’ established protocol for maintaining information, typically defining what data needs to be retained, the format in which it should be kept, how long it should be stored for, whether it should eventually be archived or deleted, who has the authority to dispose of it, and what procedure to follow in the event of a policy violation1. A data retention policy can help an organization to:

Comply with legal and regulatory requirements that mandate the retention and disposal of certain types of data, such as financial records, health records, or personal data

Reduce the risk of data breaches, theft, loss, or corruption by minimizing the amount of data stored and ensuring proper security measures are in place

Save costs and resources by optimizing the use of storage space and reducing the need for backup and recovery operations

Enhance operational efficiency and performance by eliminating unnecessary or outdated data and improving data quality and accessibility

Support business continuity and disaster recovery plans by ensuring critical data is available and recoverable in case of an emergency

Facilitate audit trails and investigations by providing evidence of data authenticity, integrity, and provenance

Therefore, by implementing a data retention policy, an organization can limit its liability associated with storing and protecting information, as well as improve its data governance and management practices.

Allowing only corporate IM solutions is the best control to mitigate the malware risk associated with an IM system, because it can prevent unauthorized or malicious IM applications from accessing the network and infecting the system with malware. Corporate IM solutions can also enforce security policies and standards, such as encryption, authentication, and logging, to protect the IM system from malware attacks. Blocking attachments in IM, blocking external IMtraffic, and encrypting IM traffic are also possible controls to mitigate the malware risk, but they are not as effective as allowing only corporate IM solutions. References: CISA Review Manual (Digital Version), Chapter 5, Section 5.4.4

When an employee exploits avulnerability, the most appropriate audit is aforensic audit, as it focuses oninvestigating and documenting security incidentsfor legal or disciplinary action.

Option A (Incorrect):Acompliance auditensures adherence to policies but does not investigate incidents in detail.

Option B (Incorrect):Application security testinghelps identify vulnerabilities but does not addressemployee misuse.

Option C (Correct):Aforensic auditgathersdigital evidence, determines how the exploit occurred, and ensures legal compliance in the investigation.

Option D (Incorrect):Penetration testingidentifies weaknesses but does notanalyze past incidents.

The best answer is A. Using automated tools to collect logs and raise alerts based on use cases.

ISACA’s log management guidance emphasizes building log management programs that use automated collection, correlation, and alerting driven by defined use cases. It specifically discusses configuring use cases and alerts so that relevant events generate actionable alerts. This creates value by improving detection, response speed, and operational visibility at scale.

Option B. Reporting results to senior management can be useful, but that is more about governance reporting than day-to-day monitoring and management.

Option C. Selecting logs only from critical systems may reduce volume, but by itself it does not provide the active monitoring and alerting needed to create operational value.

Option D. Encrypting logs before archiving protects confidentiality and integrity, but it does not best help monitor and manage logs in an operational sense.

Therefore, A is the correct answer because automated log collection and alerting based on defined use cases is the most effective way to turn operational logs into actionable organizational value.

 The finding that presents the most significant risk when reviewing the deployment of a new automated system is that data from the legacy system is not migrated correctly to the new system. Data migration is a critical process that involves transferring data from one system to another, ensuring its accuracy, completeness, integrity, and usability. If data migration is not performed correctly, it can result in data loss, corruption, inconsistency, or duplication, which can affect the functionality, performance, reliability, and security of the new system. Data migration errors can also have serious business implications, such as affecting decision making, reporting, compliance, customer service, and revenue. The other findings (A, B and D) are less significant risks, as they can be mitigated by rehiring or retraining personnel, providing user training, or adapting the system to different platforms.

 Discovery sampling is an appropriate sampling method for an IS auditor who intends to launch an intensive investigation if one exception is found. Discovery sampling is a type of attribute sampling that determines the sample size based on an acceptable risk of not finding at least one occurrence of an attribute when a given rate of occurrence exists in a population. Discovery sampling can be used by an IS auditor who wants to detect fraud or errors that have a low probability but high impacton an audit objective. The other options are not appropriate sampling methods for this purpose, as they may involve judgmental sampling, variable sampling, or stratified sampling. References:

The most effective method for detecting the presence of an unauthorized wireless access point on an internal network is A. Continuous network monitoring. This is because continuous network monitoring can capture and analyze all the wireless traffic in the network and identify any rogue or spoofed devices that may be connected to the network without authorization. Continuous network monitoring can also alert the system administrator of any suspicious or anomalous activities on the network and help to locate and remove the unauthorized wireless access point quickly.

Periodic network vulnerability assessments (B) can also help to detect unauthorized wireless access points, but they are not as effective as continuous network monitoring, because they are performed at fixed intervals and may miss some devices that are added or removed between the assessments. Review of electronic access logs © can provide some information about the devices that access the network, but they may not be able to detect devices that use fake or stolen credentials or devices that do not generate any logs. Physical security reviews (D) can help to prevent unauthorized physical access to the network ports or devices, but they may not be able to detect wireless access points that are hidden or disguised as legitimate devices.

The best solution for ensuring secure remote access to corporate resources is to use a virtual private network (VPN), as this creates an encrypted tunnel between the user’s device and the corporate network, preventing unauthorized interception or modification of data in transit. Additional firewall rules may help to restrict access to certain ports or protocols, but they do not provide encryption or authentication. Multi-factor authentication may help to verify the identity of the user, but it does not protect the data in transit. Virtual desktop may help to provide a consistent user interface and access to applications, but it does not ensure the security of thecommunication channel. References: CISA Review Manual (Digital Version), Chapter 5:Protection of Information Assets, Section 5.2: Network Security Devices and Technologies

This is the most helpful method for measuring benefits realization for a new system, because it involves evaluating the actual outcomes and impacts of the system after it has been implemented and used for a certain period of time. A post-implementation review can compare the actual benefits with the expected benefits that were defined in the business case or the benefits realization plan, and identify any gaps, issues, or opportunities for improvement. A post-implementation review can also assess the effectiveness, efficiency, and satisfaction of the system’s users, stakeholders, and customers, and provide feedback and recommendations for future enhancements or changes.

The other options are not as helpful as post-implementation review for measuring benefits realization for a new system:

Function point analysis. This is a technique that measures the size and complexity of a software system based on the number and types of functions it provides. Function point analysiscan help estimate the cost, effort, and time required to develop, maintain, or enhance a software system, but it does not measure the actual benefits or value that the system delivers to the organization or its users.

Balanced scorecard review. This is a strategic management tool that measures the performance of an organization or a business unit based on four perspectives: financial, customer, internal process, and learning and growth. A balanced scorecard review can help align the organization’s vision, mission, and goals with its activities and outcomes, but it does not measure the specific benefits or impacts of a new system.

Business impact analysis (BIA). This is a process that identifies and evaluates the potential effects of a disruption or disaster on the organization’s critical business functions and processes. A BIA can help determine the recovery priorities, objectives, and strategies for the organization in case of an emergency, but it does not measure the benefits or value of a new system.

The correct answer is C. remediation and retesting.

After a penetration test identifies findings, the next step is for management or the responsible technical teams to remediate the identified vulnerabilities and then retest to confirm the vulnerabilities were properly addressed. The value of penetration testing comes not only from identifying weaknesses but from ensuring corrective action is completed and validated.

Option A is not the best answer because analyzing system changes may be part of change management, but it is not the direct next step after penetration test findings. Option B is not the best answer because vulnerability scanning may support validation, but the more complete answer is remediation and retesting. Option D is important because penetration test reports are sensitive, but confidentiality of the report is an ongoing requirement, not the next corrective step for findings.

ISACA defines penetration testing as a live test of security defenses by mimicking real-life attackers, and Domain 5 of the CISA Exam Content Outline includes security testing tools and techniques, vulnerability management, and security monitoring.

The correct answer is B. Discuss the matter with IS audit management and executive management.

Residual risk is the risk remaining after management has implemented a risk response. Risk acceptance must be made within the organization’s risk appetite and risk tolerance. ISACA defines risk acceptance as a decision to accept risk according to the risk appetite and tolerance set by senior management, where the enterprise can assume the risk and absorb any losses.

If the IS auditor believes management accepted a risk level that is not appropriate, the auditor should not ignore the issue or simply document it without further discussion. The appropriate first step is to discuss the matter with IS audit management and executive management. This gives the organization an opportunity to reassess the decision, confirm whether the risk is within appetite, and determine whether additional treatment is required.

Option A may become appropriate later if executive management continues to accept a risk that exceeds risk appetite. ISACA guidance on follow-up activities states that when accepted risk is greater than the enterprise’s risk appetite, it should be discussed with senior management and brought to the attention of the audit committee or board if necessary.

Option C is incorrect because taking no further action would be inappropriate when the auditor believes the accepted residual risk is excessive. Option D is also incorrect because the audit report should fairly represent management’s response, including risk acceptance, rather than omitting it.

This question maps to Information Systems Auditing Process because it concerns audit judgment, communication of audit findings, escalation, and reporting.

Minimizing business downtime is critical when implementing a new system that supports an essential process like month-end closing.

Option A (Incorrect):Thebig bang approachinvolves replacing the old system with the new system all at once. This method carries ahigh riskbecause if issues arise, they may causesignificant downtimeand disruption.

Option B (Correct):Aphased approachgradually implements the system in stages, allowing users toadaptand minimizing the risk of complete failure. This strategy is ideal for critical systems that cannot afford extended downtime.

Option C (Incorrect):Thecutover approachis a variation of big bang, where the old system is shut down, and the new system is activated. This method isriskyfor month-end processes because errors can causebusiness delays.

Option D (Incorrect):Theparallel approachruns both old and new systems simultaneously to verify accuracy, but it isresource-intensiveand may not be practical for a high-volume month-end process.

 Regular scanning of hard drives is the most effective way to detect installation of unauthorized software packages by employees because it can identify any software that is not approved by the organization and may pose a security risk or violate the software policy. Communicating the policy to employees is important, but it may not prevent or detect unauthorized software installation. Logging of activity on the network can monitor network traffic, but it may not capture all software installation events. Maintaining current antivirus software can protect the system from malicious software, but it may not detect all unauthorized software packages. References:

 An external assessment of network vulnerability is a process of identifying and evaluating the weaknesses and risks that affect the security and availability of a network froman outsider’s perspective. The most important factor to verify during this process is the completeness of network asset inventory, which is a list of all the devices, systems, and software that are connected to or part of the network. A complete and accurate network asset inventory can help identify the scope and boundaries of the network, the potential attack vectors and entry points, the critical assets and dependencies, and the existing security controls and gaps. Without a complete network asset inventory, an external assessment of network vulnerability may miss some important assets or vulnerabilities, leading to inaccurate or incomplete results and recommendations.

 The best action that audit management should consider first is to reassign the audit to an internal audit subject matter expert. This is because cloud service audits require specialized knowledge and skills to assess the risks and controls associated with the cloud service provider and the cloud service customer. An IS auditor who is unfamiliar with the technologies in use and their associated risks to the business may not be able to perform an effective and efficient audit, and may miss important issues or provide inaccurate recommendations. Therefore, it is important to ensure that the IS auditor assigned to the cloud service audit has the appropriate competence and experience.

The other options are not as good as reassigning the audit to an internal audit subject matter expert. Conducting a follow-up audit after a suitable period has elapsed may not address the quality issues of the initial audit, and may also delay the identification and remediation of any problems. Rescheduling the audit assignment for the next financial year may expose the organization to unnecessary risks and may not meet the audit objectives or expectations. Extending the duration of the audit to give the auditor more time may not be feasible or cost-effective, and may not guarantee that the auditor will acquire the necessary knowledge and skills in time.

 The decision to accept an IT control risk related to data quality should be the responsibility of the business owner. The business owner is the person who has the authority and accountability for the business process that relies on the data quality. The business owner should understand the impact of data quality issues on the business objectives, performance, and compliance. The business owner should also be involved in defining the data quality requirements, assessing the data quality risks, and implementing the data quality controls or mitigation strategies.

Astress testevaluates system performance under extreme conditions, such as high user loads, to determine how the system behaves under peak traffic or resource exhaustion.

Stress Testing (Correct Answer – A)

Identifies performance bottlenecks in software applications.

Helps ensure the ERP system can handle expected workloads.

Example:Simulating thousands of concurrent users accessing the ERP system to test response times and server load capacity.

Parallel Testing (Incorrect – B)

Compares a new system with an old one but does not test system performance under load.

Regression Testing (Incorrect – C)

Tests whether recent code changes have affected existing functionality but does not focus on performance.

Interface Testing (Incorrect – D)

Checks interactions between system components but does not measure performance.

 Risk assessment is a mandatory part of the annual audit planning process, as it helps to identify and prioritize the areas that pose the highest risk to the organization’s objectives and operations. Risk assessment involves analyzing the internal and external factors that affect the organization’s risk profile, evaluating the likelihood and impact of potential events or scenarios, assessing the existing controls and mitigation strategies, and determining the residual risk level. Based on the risk assessment results, the IS auditor can allocate resources and schedule audits accordingly. A business impact analysis (BIA) is a process that identifies and evaluates the critical business functions and processes that could be disrupted by a disaster or incident, and estimates the potential impact on the organization’s operations, reputation and finances. A BIA is not a mandatory part of the annual audit planning process, but it can be used as an input for risk assessment or as a subject for audit. Fieldwork is the phase of an audit where the IS auditor collects evidence to support the audit objectives and conclusions. Fieldwork is not part of the annual audit planning process, but it is part of each individual audit engagement. A risk control matrix is a tool that maps the risks identified in a risk assessment to the controls that mitigate them. A risk control matrix is not a mandatory part of the annual audit planning process, but it can be used as an output of risk assessment or as a tool for audit testing. References: CISA Review Manual (Digital Version) 1, Chapter 1: Information Systems Auditing Process, Section 1.2: Audit Planning.

A virtual tape library (VTL) is a disk-based backup system that emulates a tape library. It provides faster backup and recovery than traditional tape systems, and it can be integrated with data deduplication and replication technologies to enhance disaster recovery. A VTL can also be replicated to an offsite location for additional protection. A VTL is the best disaster recovery solution for an environment where data virtualization is used, because it can handle large volumes of data, support multiple backup applications, and provide consistent performance.

Onsite disk-based backup systems (A) are not the best disaster recovery solution, because they are vulnerable to the same risks as the primary data center, such as fire, flood, power outage, or sabotage. Tape-based backup systems (B) are not the best disaster recovery solution, because they are slow, prone to errors, and require manual intervention. Redundant array of independent disks (RAID) (D) is not a backup system, but a storage technology that improves performance and fault tolerance by distributing data across multiple disks. RAID does not protect against data corruption, human error, or malicious attacks.

The correct answer is A. infrastructure and processes can meet current and future business needs.

Capacity management is concerned with ensuring that IT resources are sufficient to support business operations, service levels, growth, and future demand. A capacity management review should determine whether infrastructure, applications, networks, storage, processing power, and related operational processes can support both current and expected business requirements.

Option B is not the best answer because security and compliance are important, but they are not the primary purpose of a capacity management review. Option C is too narrow because capacity management is not only about acquisitions; it also includes monitoring, forecasting, utilization analysis, performance trends, and planning. Option D is also too narrow because defining capacity requirements is only one part of the broader objective. The main objective is ensuring the organization can meet current and future business needs.

ISACA’s CISA Exam Content Outline places Systems Availability and Capacity Management under Domain 4, Information Systems Operations and Business Resilience. It also includes evaluating whether IT operations and maintenance practices support organizational objectives.

A simple CISA way to remember this is: capacity management is not just about “more hardware.” It is about ensuring IT capacity is aligned with business demand, service expectations, and future growth.

A data loss prevention (DLP) tool is a software application that detects and prevents data breaches by monitoring and protecting sensitive data from unauthorized access, transfer, or use1. A DLP tool can help your organization comply with regulations, prevent insider threats, and protect your intellectual property.

Before implementing a DLP tool, the most important prerequisite is to identify where existing data resides and establish a data classification matrix. This is because you need to know what data you have, where it is stored, how sensitive it is, and who can access it. A data classification matrix is a framework that defines the categories and levels of data sensitivity, such as public, internal, confidential, or restricted2. By identifying and classifying your data, you can determine the appropriate DLP policies and controls to apply to each type of data and prevent data loss or leakage.

The senior auditor’s most appropriate course of action is to have the finding reinstated, because the auditee’s claim of correcting the problem is not sufficient evidence to support the removal of the finding. The auditor should verify that the corrective action has been implemented effectively and that it has resolved the underlying issue or risk. The auditor should also document the evidence andresults of the verification in the work papers. The other options are not appropriate, because they either accept the auditee’s claim without verification, delegate the responsibility to the auditee or escalate the issue unnecessarily. References:

 A black box penetration test is a type of security assessment that simulates an attack on a system or network without any prior knowledge of its configuration or architecture. The main objective of this test is to identify vulnerabilities and weaknesses that can be exploited by external or internal threat actors. To plan a black box penetration test, it is most important to ensure that the environment and penetration test scope have been determined. This means that the tester and the client organization have agreed on the boundaries, objectives, methods, and deliverables of the test, as well as the legal and ethical aspects of the engagement. Without a clear definition of the environment and scope, the test may not be effective, efficient, or compliant with relevant standards and regulations. Additionally, the tester may cause unintended damage or disruption to the client’s systems or networks, or violate their privacy or security policies.

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.

 A distributed security administration system is a system that allows different administrators to manage the security of different parts of the network or organization. This can provide more flexibility, scalability, and efficiency than a centralized system, where one administrator is responsible for the entire security. However, a distributed security administration system also presents some potential challenges and risks, such as:

Inconsistency and conflict among different security policies and standards

Lack of coordination and communication among different administrators

Difficulty in monitoring and auditing the overall security status and performance

Increased complexity and cost of security management and maintenance

Therefore, the greatest potential concern for implementing a distributed security administration system is that the security procedures may be inadequate to support the change. Security procedures are the rules and guidelines that define how security is implemented and enforced in an organization. They include policies, standards, processes, roles, responsibilities, controls, and metrics. Security procedures should be aligned with the business objectives, risks, and requirements of the organization, as well as the best practices and regulations in the industry. Security procedures should also be reviewed and updated regularly to reflect the changes in the environment, technology, and threats.

If the security procedures are not adequate to support the change from a centralized to a distributed security administration system, the organization may face increased security risks, such as unauthorized access, data breaches, compliance violations, reputation damage, and financial losses. Therefore, it is essential to ensure that the security procedures are revised and adapted to suit the new system, and that they are communicated and enforced effectively across the organization.

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.

Recovery facilities providing a redundant combination of Internet connections to the local communications loop is an example of last-mile circuit protection. Last-mile circuit protection is a type of telecommunications continuity that ensures the availability and redundancy of the final segment of the network that connects the end-user to the service provider. The local communications loop, also known as the local loop or subscriber line, is the physical link between the customer premises and the nearest central office or point of presence of the service provider. Byhavingmultiple Internet connections from different providers or technologies, such as cable, DSL, fiber, wireless, or satellite, the recoveryfacilities can avoid losing connectivity in case one of the connections fails or is disrupted by a disaster5.

The most effective way to minimize downtime during system conversions is to use a parallel run. A parallel run is a method of system conversion where both the old and new systems operate simultaneously for a period of time until the new system is verified to be functioning correctly. Thisreduces the risk of errors, data loss, or system failure during conversion and allows for a smooth transition from one system to another. References: CISA Review Manual, 27th Edition, page 467

The primary role of an audit reviewer with regard to evidence is to ensure that evidence is sufficient to support audit conclusions. Evidence is the information obtained by the auditor to provide a reasonable basis for the audit opinion or findings. Evidence should be sufficient, reliable, relevant, and useful to support the audit objectives and criteria. The audit reviewer should evaluate the quality and quantity of evidence collected by the auditor and determine if it is adequate to draw valid conclusions and recommendations. Ensuring unauthorized individuals do not tamper with evidence after it has been captured is a role of the auditor, not the audit reviewer. The auditor is responsible for safeguarding the evidence from loss, damage, or alteration during the audit process. The auditor should also document the source, date, and method of obtaining the evidence, as well as any limitations or restrictions on its use or disclosure. Ensuring appropriate statistical sampling methods were used is a role of the auditor, not the audit reviewer. The auditor is responsible for selecting an appropriate sampling method and technique that can provide sufficient evidence to achieve the audit objectives and criteria. The auditor should also document the sampling plan, population, sample size, selection method, evaluation method, and results. Ensuring evidence is labeled to show it was obtained from an approved source is a role of the auditor, not the audit reviewer. The auditor is responsible for labeling the evidence to indicate its origin, nature, and ownership. The auditor should also ensure that the evidence is obtained from reliable and credible sources that can be verified and corroborated. References: ISACA CISA Review Manual 27th Edition, page 295

 The best option to support the organization’s objectives of protecting data confidentiality while transporting data is encryption. Encryption is a process of transforming data into an unreadable form using a secret key or algorithm, so that only authorized parties can access the original data. Encryption protects the confidentiality of data in transit by preventing unauthorized interception,modification, or disclosure of the data. Encryption can also help comply with data privacy and security regulations, such as the GDPR and HIPAA.

The other options are not as effective as encryption in protecting data confidentiality while transporting data. Cryptographic hashes are mathematical functions that generate a fixed-length output from an input, but they do not encrypt the data. Hashes are used to verify the integrity and authenticity of data, but they do not prevent unauthorized access to the data. Virtual local area network (VLAN) is a logical grouping of network devices that share the same broadcast domain, but they do not encrypt the data. VLANs can improve network performance and security by isolating traffic, but they do not protect the data from being intercepted or modified by external attackers. Dedicated lines are physical connections that provide exclusive access to a network or service, but they do not encrypt the data. Dedicated lines can offer higher bandwidth and reliability, but they do not guarantee the confidentiality of the data from being compromised by physical tampering or eavesdropping.

The best way to obtain assurance that certain automated calculations comply with the regulatory requirements is to re-perform the calculation with audit software. This will allow the auditor to independently verify the accuracy and validity of the calculation and compare it with the expected results. Reviewing sign-off documentation, source code, or user acceptance test results may not provide sufficient evidence or assurance that the calculation is correct and compliant. References:

Enterprise architecture (EA) governance ensures that IT and business alignment is maintained and that new processes and technologies integrate well with existing structures.

Option A (Correct):The primary purpose of EA governance is to ensure that new technologies, processes, and systems align and harmonize with existing architecture to maintain operational efficiency and consistency.

Option B (Incorrect):While adaptability to emerging technology trends is important, EA governance focuses more on structure, consistency, and compliance rather than just adaptability.

Option C (Incorrect):Compliance with regulations is crucial, but it is just one component of governance. EA governance has a broader scope, including strategic alignment and process integration.

Option D (Incorrect):Ensuring ROI is an important financial consideration, but it is not themainobjective of EA governance.

Comprehensive and Detailed in-Depth Explanation:

The primary focus when reviewing operational database management in a cloud environment should be the security settings configuration. Cloud environments often have complex and customizable security configurations, and any misconfiguration can lead to data breaches or unauthorized access. Ensuring proper security settings helps maintain data confidentiality, integrity, and availability.

Cloud vendor security certifications (Option A) are important but do not directly address how security is configured. Auto-scaling of provisioning costs (Option B) relates to resource management rather than security. Large-scale data transfers (Option D) may be relevant, but security settings directly impact data protection.

ISACA CISA Reference: Domain 5 - Protection of Information Assets

IT application owners having sole responsibility for architecture approval (B) is a major concern because it indicates a lack of oversight and segregation of duties. EA decisions should be reviewed by a cross-functional governance body to ensure alignment with security, compliance, and business objectives.

Other options:

The CIO chairing the review board (A) may indicate centralized leadership but is not inherently a risk.

EA governing non-IT projects (C) may indicate scope expansion but is not a security risk.

Security requirements being reviewed (D) is a best practice and not a concern.

Business processes should be the primary focus of an IS auditor when developing a risk-based IS audit program, because they represent the core activities and functions of the organization that support its objectives and goals. Business processes also involve the use of IT resources and systems that may pose risks to the organization’s performance and compliance. A risk-based IS audit program should identify and assess the risks associated with the business processes and determine the appropriate audit scope and procedures to provide assurance on their effectiveness and efficiency. Portfolio management, business plans, and IT strategic plans are also relevant factors for developing a risk-based IS audit program, but they are not as important as business processes. References: CISA Review Manual (Digital Version), Chapter 2, Section 2.2.1

An IT steering committee is a group of senior executives and stakeholders who provide strategic direction, guidance, and oversight for the IT function of an organization. An IT steering committee can help to improve the maturity of the IT team by ensuring that the IT initiatives are aligned with the business goals and objectives, that the IT resources are allocated and utilized effectively and efficiently, and that the IT performance and value are measuredand communicated. An IT steering committee can also help to resolve conflicts, prioritize demands, and foster collaboration among the IT project managers and other business units.

The Impact of Poor IT Audit Planning and Mitigating Audit Risk

IS Audit Basics: The Components of the IT Audit Report

The best indicator of the effectiveness of an organization’s incident response program is the financial impact per security event. This metric measures the direct and indirect costs associated with security incidents, such as loss of revenue, reputation damage, legal fees, recovery expenses, and fines. By reducing the financial impact per security event, the organization can demonstrate that its incident response program is effective in mitigating the consequences of security breaches and restoring normal operations as quickly as possible. Number of successful penetration tests, percentage of protected business applications, and number of security vulnerability patches are indicators of the security posture of the organization, but they do not reflect the effectiveness of the incident response program. References: ISACA Journal Article: Measuring Incident Response Effectiveness

The correct answer is D. The management of the client organization has approved the scope of testing.

Before any penetration test begins, especially a black-box test, the most important requirement is formal management approval of the scope. Penetration testing can be disruptive and may involve activities that resemble real attacks. Therefore, the tester must have clear authorization, approved scope, rules of engagement, timing, target systems, restrictions, and escalation procedures before testing starts.

ISACA guidance on penetration testing emphasizes the importance of clear documentation of project scope, rules of engagement, and client authorization to demonstrate that testing is being conducted legally and ethically. ISACA also explains that planning security testing requires defining scope and out-of-scope items, including what will be tested, where testing will occur from, when testing should not be performed, which hosts are restricted, and who will perform the testing.

Option A is useful because tactics, techniques, and procedures help define how the test will be performed, but they should not override approved scope and authorization. Option B is not required for a black-box penetration test because black-box testing intentionally gives the tester little or no internal knowledge of the environment. Option C is important because results must be documented and communicated, but reporting happens after testing; formal authorization and scope approval must come first.

This question maps mainly to Protection of Information Assets, because penetration testing is a security testing technique used to evaluate vulnerabilities and the effectiveness of security controls. ISACA’s CISA Exam Content Outline includes security testing tools and techniques, threat and vulnerability management, and security monitoring under Domain 5.

 The main purpose of an information security management system (ISMS) is to reduce the frequency and impact of information security incidents. An ISMS is a systematic approach to managing information security risks, policies, procedures, and controls within an organization. An ISMS aims to ensure the confidentiality, integrity, and availability of information assets, as well as to comply with relevant laws and regulations. The other options are not the main purpose of an ISMS, but rather some of its possible benefits or components. References:

 The best recommendation for an organization that does not have a process to identify and correct records that do not get transferred to the receiving system is to implement software to perform automatic reconciliations of data between systems. This will ensure that the data integrity and completeness are maintained and that any errors or discrepancies are detected and resolved in a timely manner. Enabling encryption, decryption, and electronic signing of data files may enhance the data security and authenticity, but not the data accuracy or consistency. Having coders perform manual reconciliation of data between systems may be prone to human errors and inefficiencies. Automating the transfer of data between systems as much as feasible may reduce the chances of data loss or corruption, but not eliminate them completely. References: ISAudit and Assurance Standards, section “Standard 1202: Risk Assessment in Planning”

 An IT risk assessment is the process of identifying and assessing the threats facing an organization’s information systems, networks, and data. An IT risk assessment helps an organization to understand its current risk profile, prioritize its risks, and implement appropriate controls to mitigate them. An IT risk assessment also helps an organization to comply with relevant laws and standards, such as ISO 27001 or CMMC.

One of the key steps in an IT risk assessment is the identification of vulnerabilities. Vulnerabilities are the weaknesses or gaps in an organization’s information security that could be exploited by internal or external threats. Vulnerabilities can exist in various aspects of an organization’s information security, such as:

Hardware: The physical devices and components that store or process information

Software: The applications and programs that run on hardware devices

Network: The communication channels and protocols that connect hardware devices

Data: The information that is stored or transmitted by hardware devices or software applications

People: The users or personnel who access or manage information systems or data

Processes: The procedures or workflows that govern how information systems or data are used or maintained

By identifying vulnerabilities in each of these aspects, an organization can assess its exposure to potential threats, such as hackers, malware, natural disasters, human errors, or sabotage. By identifying vulnerabilities, an organization can also determine its risk level for each threat scenario, based on the likelihood and impact of a successful attack. By identifying vulnerabilities, an organization can also identify the existing or required controls to prevent or reduce the impact of an attack.

Therefore, an IT risk assessment should include the identification of vulnerabilities as a crucial component.

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.

 Backup procedures for an organization’s critical data are considered to be corrective controls, as they are designed to restore normal operations after a disruption or failure. Corrective controls aim to minimize the impact of an incident and prevent recurrence. Directive, detective and compensating controls are not related to backup procedures. Directive controls are intended to guide or instruct users to follow policies and procedures. Detective controls are intended to identify and report incidents or violations. Compensating controls are intended to mitigate the risk of a missing or ineffective primary control. References: CISA Review Manual (Digital Version), Chapter 2, Section 2.11

A mesh configuration provides the greatest fault tolerance. ISACA’s glossary explicitly defines mesh topology as “a fault-tolerant topology in which network nodes and endpoints are mostly, if not fully, interconnected.” That directly answers the question.

Option D is correct because a mesh topology provides multiple alternate communication paths. If one link or node fails, traffic can often be rerouted through other paths, making the network more resilient than star, ring, or bus topologies.

Option A is less fault tolerant because the central hub or switch can become a single point of failure.

Option B is less fault tolerant because failure in the ring can disrupt communication unless specialized redundancy exists.

Option C is the least fault tolerant among these common topologies because the shared backbone can become a major single point of failure.

Therefore, D is the best answer, and ISACA’s glossary directly supports it.

 The most important thing for the organization to ensure when reducing the actual retention period for media containing completed low-value transactions is that the retention period complies with data owner responsibilities. Data owners are accountable for the quality, security, and availability of the data under their control. They are also responsible for defining and enforcing data retention policies that comply with legal, regulatory, contractual, and business requirements. Data owners should be consulted and involved in any decision that affects the retention period of their data, as they are ultimately liable for any consequences of data loss or breach.

The policy includes a strong risk-based approach, the retention period allows for review during the year-end audit, and the total transaction amount has no impact on financial reporting are not the most important things for the organization to ensure when reducing the actual retention period for media containing completed low-value transactions. These are possible factors or benefits that may influence or justify the decision, but they do not override or replace the data owner responsibilities.

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.

Unauthorized code deployment presents acritical security and operational risk.

Option A (Incorrect):Whiledocumentation issuescan cause confusion, they do not directlyjeopardizesecurity or system stability.

Option B (Correct):Deploying code without authorizationbypasseschange management controls, potentially leading to security vulnerabilities, system failures, or compliance violations. This is thegreatest risk.

Option C (Incorrect):Overwriting files can cause issues but isless severethan unauthorized deployment, which may introducemalware or untested features.

Option D (Incorrect):An unresolved bug may causeperformance issues, butunauthorized deploymentposes a higher security and compliance risk.

he design of an incident management process should include prioritization criteria to ensure that incidents are handled according to their impact and urgency. Without prioritization criteria, the organization may not be able to allocate resources effectively and respond to incidents in a timely manner. Expected time to resolve incidents, service management standards, and metrics reporting are important aspects of incident management, but they are not as critical as prioritization criteria for the design of the process. References: ISACA Journal Article: Incident Management: A Practical Approach

Ransomwareis a type of malicious software that encrypts the victim’s data and demands a ransom for its decryption1. Ransomware attacks can cause significant damage to an organization’s operations, reputation, andfinances1. Therefore, it is important to mitigate the impact of ransomware attacks by implementing effective prevention and recovery strategies.

One of the best ways to mitigate the impact of ransomware attacks is to back up data frequently12345. Data backups are copies of the organization’s data that are stored in a separate location or medium, such as an external harddrive, cloud storage, or tape2. Data backupscan help the organization restore its data in case of a ransomware attack, without paying the ransom or losing valuable information2. Data backups shouldbe performed regularly, preferably daily or weekly, depending on the criticality and volume of the data2. Data backups should also be tested periodically to ensure their integrity and usability2.

The other options are not as effective as backing up data frequently in mitigating the impact of ransomware attacks. Invoking the disaster recovery plan (DRP) is a reactive measure that can help the organization resume its operations after a ransomware attack, but it does not prevent or reduce the damage caused by the attack3. Paying the ransom is not a recommended option, as it does not guarantee the decryption of the data or the deletion of the stolen data by the attackers. Paying the ransom also encourages further attacks and funds criminal activities14. Requiring password changes for administrative accounts is a good security practice, but it is not sufficient to prevent or recover from ransomware attacks. Ransomware attacks can exploit other vulnerabilities, such as phishing emails, outdated software, or weak network security15.

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 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

The most effective method to verify that a service vendor keeps control levels as required by the client is to conduct periodic on-site assessments using agreed-upon criteria. On-site assessments can provide direct evidence of whether the vendor’s controls are operating effectively and consistently in accordance with the client’s expectations and requirements. Agreed-upon criteria can ensure that the assessments are objective, relevant, and reliable. The other options are not as effective as on-site assessments in verifying the vendor’s control levels. Periodically reviewing the SLA with the vendor can help monitor whether the vendor meets its contractual obligations and service standards, but it does not provide assurance of whether the vendor’s controls are adequate or sufficient. Conducting an unannounced vulnerability assessment of vendor’s IT systems can help identify any weaknesses or gaps in the vendor’s security controls, but it may violate the terms and conditions of the vendor-client relationship or cause operational disruptions. Obtaining evidence of the vendor’s CSA can provide some indication of whether the vendor’s controls are self-monitored and reported, but it does not verify whether the vendor’s controls are independent or accurate. References: CISA Review Manual (Digital Version), Chapter 5, Section 5.4

 The best recommendation to mitigate the risk of eavesdropping associated with an API integration implementation is to implement Transport Layer Security (TLS). TLS is a cryptographic protocol that provides secure communication over a network by encrypting the data in transit and authenticating the parties involved. TLS can prevent unauthorized parties from intercepting, modifying or tampering with the data exchanged between the API endpoints. Encrypting the XML file, implementing SOAP, and masking the API endpoints are not sufficient to mitigate the risk of eavesdropping, as they do not provide end-to-end encryption or authentication for the API communication. References: IS Auditand Assurance Tools and Techniques, CISA Certification | Certified Information Systems Auditor | ISACA

Option A (Correct):Monitoring data movementallows organizations todetect and preventunauthorized access, data exfiltration, and cloud-based threats.

Option B (Incorrect):Along-term contractdoes not inherentlyimprove security monitoring.

Option C (Incorrect):Reviewing policies helps withgovernance, but it does notactively detect threats.

Option D (Incorrect):Firewallsprotectnetwork perimeters, while CASBs focus oncloud security, making this anineffective measurefor CASB threat detection.

Linking incidents to problem management activities would most effectively help to reduce the number of repeated incidents in an organization, because problem management aims to identify and eliminate the root causes of incidents and prevent their recurrence. Testing incident response plans, prioritizing incidents, and training incident management teams are all good practices, but they do not directly address the issue of repeated incidents. References: ISACA ITAF 3rd Edition Section 3600

Data loss can occur due to various reasons, such as accidental deletion, hardware failure, malware infection, theft, or unauthorized access. Data classification procedures can help to identify and protect sensitive data, but they are not sufficient to prevent data loss. The most effective way to protect against data loss is to conduct periodic security awareness training for employees, which can educate them on the importance of data security, the best practices for data handling and storage, and the common threats and risks to data. 

Assessing and tracking all compliance audit findings is the best way to support the effectiveness of a compliance program. This allows an organization to identify areas of non-compliance, take corrective action, and monitor improvements over time12. While implementing an awareness plan, using a governance, risk, and compliance (GRC) tool, and monitoring applicable regulations can contribute to a compliance program, they do not provide the same level of continuous improvement and effectiveness as assessing and tracking audit findings.

 Internet Protocol (IP) address restrictions are used in a firewall to protect the entity’s internal resources by allowing or denying access to specific IP addresses or ranges of IP addresses based on predefined rules. Remote access servers, Secure Sockets Layers (SSLs), and failover services are not directly related to firewall protection, but rather to other aspects of network security, such as authentication, encryption, and availability. References: CISA Review Manual (Digital Version), Chapter 5: Protection of Information Assets, Section 5.2: Network Security Devices and Technologies

Validation checks are a type of data quality control that helps to ensure the integrity of data for a system interface. Validation checks verify that the data entered or transferred between systems is correct, consistent, and conforms to predefined rules or standards. Validation checks can prevent or detect errors, anomalies, or inconsistencies in the data that may affect the system’s functionality, performance, or security.

Option C is correct because validation checks are a common and effective method of ensuring data integrity for a system interface. Validation checks can be performed at various stages of the data lifecycle, such as input, processing, output, or storage. Validation checks can also be applied to different types of data, such as data types, codes, ranges, formats, consistency, and uniqueness.

Option A is incorrect because system interface testing is a type of software testing that verifies the interaction between two separate systems or components of a system. System interface testing does not directly ensure the integrity of data for a system interface, but rather the functionality and reliability of the interface itself. System interface testing may use validation checks as part of its test cases, but it is not the same as validation checks.

Option B is incorrect because user acceptance testing (UAT) is a type of software testing that evaluates whether the system meets the user’s expectations and requirements. UAT does not directly ensure the integrity of data for a system interface, but rather the usability and acceptability of the system from the user’s perspective. UAT may use validation checks as part of its test scenarios, but it is not the same as validation checks.

Option D is incorrect because audit logs are records of events and activities that occur within a system or network. Audit logs do not directly ensure the integrity of data for a system interface, but rather provide evidence and accountability for the system’s operations and security. Audit logs may use validation checks as part of their analysis or reporting, but they are not the same as validation checks.

The IS auditor’s best recommendation is to ensure that programmers cannot access code after the completion of program edits. This is because programmers who have access to code after editing may introduce unauthorized or malicious changes that could compromise the security, functionality, or performance of the application. By restricting access to code after editing, the organization can ensure that only authorized and tested code is released into production, and prevent any tampering or reoccurrence of the same issue.

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.

Forensic evidence must be legally admissible, unaltered, and properly collected to support prosecution.

Option A (Incorrect):While an IDS helpsdetectcybercrime, it does not ensure evidence collection or legal admissibility.

Option B (Correct):Theprofessional collection of unaltered evidencefollows forensic standards, includingchain of custody, ensuring that the evidence is admissible in court. This is the most critical factor in prosecuting cybercriminals.

Option C (Incorrect):Internal legal reporting is necessary but does not directly impactevidence preservation, which is key for legal action.

Option D (Incorrect):Law enforcement involvement is important, but withoutproperly collected evidence, prosecution is unlikely to succeed.

Referential integrity is a property of data that ensures that all references between tables are valid and consistent. Disabling referential integrity controls can result in orphaned records, data anomalies, and inaccurate queries. The most effective way to compensate for the lack of referential integrity is to perform periodic table link checks, which verify that all foreign keys match existing primary keys in the related tables. More frequent data backups, concurrent access controls, and performance monitoring tools do not address the issue of data consistency and accuracy. References: ISACACISA Review Manual 27th Edition, page 291

The greatest concern is the lack of documentation for the basic assumptions and formulas used to develop the decision logic. In AI and algorithmic systems, undocumented assumptions, logic, and model foundations undermine transparency, explainability, validation, governance, auditability, and the ability to assess whether outputs are reliable and appropriate. ISACA’s AI audit guidance specifically emphasizes questioning assumptions and identifying conditions that are taken for granted within AI systems.

Option D is correct because without documented assumptions and formulas, neither management nor the auditor can effectively understand how the AI system reaches conclusions, validate whether it is working as intended, assess bias or error, or confirm whether controls are adequate. ISACA’s AI-related guidance highlights that assumptions embedded in AI systems must be examined because changing environments, unreliable data, or hidden logic can create serious control weaknesses.

Option A is not the greatest concern by itself. Outsourcing development to vendors may introduce third-party risk, but vendor use is common and can be controlled through contracts, review, validation, and oversight. The mere fact of outsourcing does not create as severe a control weakness as undocumented decision logic.

Option B is a potential concern because annual review might be too infrequent depending on the system’s risk and rate of change. However, even with infrequent review, the organization would still have documented policy and decision logic to examine. A complete lack of documentation of assumptions and formulas is more serious because it prevents meaningful review altogether.

Option C is also a concern, but vendor maintenance access can be managed through access controls, logging, approvals, segregation, and monitoring. Access by contracted developers is not inherently unacceptable. The more fundamental weakness is the absence of documented logic foundations, which affects governance and auditability at the core.

Therefore, the greatest concern is D because undocumented assumptions and formulas make the AI system insufficiently transparent and far harder to audit, validate, and control.

 Validating that assets are protected according to assigned classification is the primary role of the IS auditor in an organization’s information classification process. An IS auditor should evaluate whether the information security controls are adequate and effective in safeguarding the information assets based on their classification levels. The other options are not the primary role of the IS auditor, but rather the responsibilities of the information owners, custodians, or security managers. References:

The type of review that is most important to conduct when an IS auditor is informed that a recent internal exploitation of a bug has been discovered in a business application is C. Forensic audit. A forensic audit is a type ofaudit that involves collecting, analyzing, and preserving evidence of fraud, corruption, or other illegal or unethical activities1. A forensic audit can help the IS auditor to identify and document the source, scope, and impact of the exploitation, as well as the perpetrators, motives, and methods involved. A forensic audit can also help the IS auditor to provide recommendations for preventing or mitigating future exploitations, and to support any legal actions or investigations that may arise from the incident2.

A recovery point objective (RPO) is the maximum acceptable amount of data loss after an unplanned data-loss incident, expressed as an amount of time. This is generally thought of as the point in time before the event at which data can be successfully recovered– that is, the time elapsed since the most recent reliable backup1. RPOs are important to consider when reviewing an organization’s defined data backup and restoration procedures, because they determine how frequently the organization needs to perform backups, and how much data it can afford to lose in case of a disaster. RPOs are usually defined based on the business impact and criticality of the data, as well as the compliance and regulatory requirements. For example, a financial institution may have a very low RPO (such as a few minutes or seconds) for its transactional data, while a research institute may have a higher RPO (such as a few hours or days) for its experimental data.

The other possible options are:

A. Business continuity plan (BCP): A BCP is a document that outlines how an organization will continue to operate or resume its critical functions and processes in the event of a disruption or disaster. A BCP includes various elements, such as risk assessment, business impact analysis, recovery strategies, roles and responsibilities, communication plan, and testing and maintenance. A BCP is related to an organization’s defined data backup and restoration procedures, but it is not the most important factor to consider when reviewing them. A BCP defines the recovery objectives and strategies for the entire organization, while the data backup and restoration procedures are more specific and technical in nature.

C. Mean time to restore (MTTR): MTTR is a metric that measures the average time it takes to restore a system or service after a failure or outage. MTTR is an indicator of the efficiency and effectiveness of an organization’s recovery process, as well as the availability and reliability of its systems or services. MTTR is related to an organization’s defined data backup and restoration procedures, but it is not the most important factor to consider when reviewing them. MTTR reflects the actual performance of the recovery process, while the data backup and restoration procedures define the expected steps and actions for the recovery process.

D. Mean time between failures (MTBF): MTBF is a metric that measures the average time between failures or outages of a system or service. MTBF is an indicator of the quality and durability of an organization’s systems or services, as well as their susceptibility to failures or outages. MTBF is related to an organization’s defined data backup and restoration procedures, but it is not the most important factor to consider when reviewing them. MTBF reflects the potential frequency of failures or outages, while the data backup and restoration procedures define the contingency plans for failures or outages.

 During an audit of a reciprocal disaster recovery agreement between two companies, the IS auditor would be most concerned with the allocation of resources during an emergency. A reciprocal disaster recovery agreement is an arrangement by which one organization agrees to use another’s resources in the event of a business continuity event or incident. The IS auditor would need to ensure that both parties have clearly defined their roles and responsibilities, their resource requirements, their priority levels, their communication channels, and their escalation procedures in case of a disaster. The IS auditor would also need to verify that both parties have tested their agreement and have updated it regularly to reflect any changes in their business environments. The frequency of system testing is not as critical as the allocation of resources during an emergency, because system testing can be performed periodically or on demand, while resource allocation is a dynamic and complex process that requires careful planning and coordination. The differences in IS policies and procedures are not as critical as the allocation of resources during an emergency, because both parties can agree on common standards and protocols for their disaster recovery operations, or they can adapt their policies and procedures to suit each other’s needs. The maintenance of hardware and software compatibility is not as critical as the allocation of resources during an emergency, because both parties can use compatible or interoperable systems, or they can use virtualization or cloud computing technologies to overcome any compatibility issues. References: ISACACISA Review Manual 27th Edition, page 281

 The most important thing to determine when conducting a post-implementation review is whether success criteria have been achieved. A post-implementation review is a process of evaluating the results and outcomes of a project or initiative after it has been completed and implemented. The success criteria are the measurable indicators that define what constitutes a successful project or initiative in terms of its objectives, benefits, quality, performance, and stakeholder satisfaction. The IS auditor should verify whether the success criteria have been achieved by comparing the actual results and outcomes with the expected or planned ones, and by assessing whether they meet or exceed the expectations and requirements of the stakeholders. The IS auditor should also identify any gaps, issues, or risks that may affect the sustainability or scalability of the project or initiative, and provide recommendations for improvement or remediation. The other options are not as important as determining whether success criteria have been achieved when conducting a post-implementation review, because they either focus on specific aspects or components of the project or initiative rather than theoverall value proposition, or they are part of the pre-implementation or implementation phases rather than the post-implementation phase. References: CISA Review Manual (Digital Version)1, Chapter 4, Section 4.2.3

The first action that an IS auditor should take when finding a high-risk vulnerability in a public-facing web server used to process online customer payments is to identify compensating controls. Compensating controls are alternative or additional controls that provide reasonable assurance of mitigating the risk of exploiting the vulnerability. The IS auditor should assess the effectiveness of the compensating controls and determine whether they reduce the risk to an acceptable level. If not, the IS auditor should recommend remediation actions to address the vulnerability. Documenting the exception in an audit report is an important action, but it should not be the first action, as it does not address the urgency of the situation. Reviewing security incident reports is a useful action, but it should not be the first action, as it does not provide assurance of preventing future incidents. Notifying the audit committee is a necessary action, but it should not be the first action, as it does not involve taking any corrective measures. References:

Visualization technology is the use of software and hardware to create graphical representations of data, such as charts, graphs, maps, images, etc. Visualization technology can help users to understand, analyze, and communicate complex and large amounts of data in an intuitive and engaging way1.

One of the primary advantages of using visualization technology for corporate applications is that it can improve the utilization of resources, such as time, money, human capital, and physical assets. Some of the ways that visualization technology can achieve this are:

Visualization technology can help users to quickly and easily explore, filter, and interact with data, reducing the need for manual data processing and analysis1. This can save time and effort for both data producers and consumers, and allow them to focus on more value-added tasks.

Visualization technology can help users to discover patterns, trends, outliers, correlations, and causations in data that may otherwise be hidden or overlooked in traditional reports or tables1. This can enable users to make better and faster decisions based on data-driven insights, and optimize their strategies and actions accordingly.

Visualization technology can help users to communicate and share data more effectively and persuasively with different audiences, such as customers, partners,investors, regulators, etc1. This can enhance the reputation and credibility of the organization, and foster collaboration and innovation among stakeholders.

Visualization technology can help users to monitor and measure the performance and impact of their activities, products, services, or processes1. This can help users to identify problems or opportunities for improvement, and adjust their plans or actions accordingly.

Visualization technology can help users to create engaging and interactive experiences for their customers or end-users1. This can increase customer satisfaction and loyalty, and generate more revenue or value for the organization.

Therefore, using visualization technology for corporate applications can help organizations to better utilize their resources and achieve their goals.

The best reason for an IS auditor to emphasize to management the importance of using an IT governance framework is that frameworks can be tailored and optimized for different organizations. An IT governance framework is a set of principles, guidelines, and processes that help an organization align its IT strategy with its business goals, manage IT risks and performance, and deliver value from IT investments. An IT governance framework can be adapted and customized to suit the specific needs, context, and culture of each organization, taking into account factors such as size, industry, maturity, objectives, and stakeholders. An IT governance framework can also help an organization adopt best practices and standards from various sources, such as COBIT2, ITIL3, ISO/IEC 200004, and others.

The other options are not as good as option B, as they may not capture the full scope or benefits of using an IT governance framework. Frameworks enable IT benchmarks against competitors, but this is not the main purpose or advantage of using an IT governance framework. Frameworks help facilitate control self-assessments (CSAs), but this is only one aspect or tool of an IT governance framework. Frameworks help organizations understand and manage IT risk, but this is also only one outcome or objective of an IT governance framework.

The best approach for management in developing a test plan is to use processing parameters that are simulated by production entities and customers. This is because using realistic data and scenarios can help to evaluate the functionality, performance, reliability, and security of the new system under actual operating conditions and expectations. Using processing parameters that are randomly selected by a test generator, provided by the vendor of the application, or randomly selected by the user may not be sufficient or representative of the production environment and may not reveal all the potential issues or defects of the new system. References: [ISACA CISA Review Manual 27th Edition], page 266.

The management decision that presents the greatest risk associated with data leakage is not providing security awareness training to staff. This is because staff are often the weakest link in the information security chain, and they may unintentionally or maliciously leak sensitive data through various channels, such as email, social media, cloud storage, or removable media. Security awareness training is essential to educate staff on the importance of protecting data, the policies and procedures for handling data, and the best practices for preventing and reporting data leakage incidents. Not requiring desktops to be encrypted, allowing staff to work remotely, and not updating security policies in the past year are also management decisions that may increase the risk of data leakage, but they are not as significant as not providing security awareness training to staff. Encryption, remote work, and security policies are technical or administrative controls that can be implemented or enforced by management, but they cannot fully prevent or mitigate human errors or malicious actions by staff. References: CISA Review Manual (Digital Version), [ISACA Privacy Principles and Program Management Guide]

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, Now Is the Time for IT Auditors to Perform Advisory Pre-Implementation Reviews — emphasizes engaging leadership and planning around risk and control deficiencies.

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

Unauthorized modifications to scripts (D) pose the greatest risk because they can lead to unintended processing errors, security vulnerabilities, or fraudulent activities. Change management controls should be in place to prevent unauthorized script changes.

Other options:

Minor overrides not authorized (A) is a concern but does not pose as much risk as unauthorized script changes.

Bots incapable of learning (B) is a limitation but not a security risk.

Recording user interactions (C) raises privacy concerns but is not as critical as unauthorized script modifications.

 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

 Data classification is the process of organizing and labeling data into categories based on file type, contents, and other metadata. Data classification helps organizations answer important questions about their data that inform how they mitigate risk and manage data governance policies. Data classification also enables appropriate protection measures, and efficient search, retrieval and use of each data category12.

While evaluating the data classification process of an organization, an IS auditor’s primary focus should be on whether data is correctly classified. This means that the data is assigned to the appropriate classification level based on its sensitivity, importance, integrity, availability, compliance requirements, and business value. Correct data classification ensures that the data is protected according to its risk level, and that the organization can comply with relevant laws and regulations that apply to different types of data3.

The other three options are not the primary focus of an IS auditor while evaluating the data classification process, although they may be relevant or useful for certain aspects of data management. Data classifications are automated means that the organization uses software tools or algorithms to analyze and label data based on predefined rules or criteria. This can improve the efficiency and consistency of data classification, but it does not guarantee that the data is correctly classified. The IS auditor still needs to verify the accuracy and validity of the automated classifications, and check for any errors or anomalies.

A data dictionary is maintained means that the organization keeps a record of the definitions, formats, sources, and relationships of the data elements in its systems or databases. This can enhance the understanding and usability of the data, but it does not ensure that the data is correctly classified. The IS auditor still needs to examine the content and context of the data, and compare it with the classification criteria and policies.

Data retention requirements are clearly defined means that the organization specifies how long it will keep different types of data, and when it will delete or archive them. This can help reduce storage costs, improve performance, and comply with legal obligations, but it does not ensure that the data is correctly classified. The IS auditor still needs to assess whether the data is stored and protected according to its classification level, and whether the retention periods are appropriate for each type of data.

Therefore, data is correctly classified is the best answer.

 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

Theprimary concernwhen auditing an AI-powered chatbot is ensuring thesafeguarding of personal datato comply with privacy regulations such asGDPR, CCPA, and ISO 27701. AI chatbots process customer inquiries, often handling sensitive personal data.

Safeguarding of Personal Data (Correct Answer – A)

Ensures compliance with data protection laws.

Reduces the risk of unauthorized access or data leakage.

Example:An AI chatbot collecting customer financial information must follow encryption and access control policies.

Compliance with Industry Standards (Incorrect – B)

Important, but protecting customer data takes priority over general compliance.

Speed and Accuracy of Chatbot Responses (Incorrect – C)

A performance metric, but not a primary audit focus.

AI’s Ability to Handle Multiple Queries (Incorrect – D)

Efficiency metric, but does not address security risks.

The sampling method in which the entire sample is considered to be irregular if a single error is found is discovery sampling. Discovery sampling is a type of statistical sampling that is used to test for the existence of at least one occurrence of a specific characteristic or condition in a population. Discovery sampling is often used when the auditor expects the characteristic or condition to be very rare or nonexistent, and when any occurrence would have a significant impact on the audit objective. For example, discovery sampling can be used to test for fraud, noncompliance, or material misstatement.

Discovery sampling works by setting a very low tolerable error rate (the maximum rate of occurrence of the characteristic or condition that the auditor is willing to accept) and a high confidence level (the degree of assurance that the auditor wants to obtain). The auditor then selects a sample from the population using a random or systematic method, and examines each item in the sample for the presence or absence of the characteristic or condition. If no error is found in the sample, the auditor can conclude with a high level of confidence that the characteristic or condition does not exist or is very rare in the population. However, if one or more errors are found in the sample, the auditor cannot draw any conclusion about the population and must either expand the sample size or perform alternative procedures.

Discovery sampling differs from other sampling methods in that it does not allow for any errors in the sample. Other sampling methods, such as variable sampling, stop-or-go sampling, or judgmental sampling, can tolerate some errors in the sample and use them to estimate the error rate or amount in the population. However, discovery sampling is designed to test for zero-tolerance situations, where any error would be unacceptable or material. Therefore, discovery sampling considers the entire sample to be irregular if a single error is found.

 The best compensating control when segregation of duties is lacking in a small IS department is transaction log review. Transaction log review can help detect any unauthorized or fraudulent activities performed by IS staff who have access to multiple functions or systems. Transaction log review can also provide an audit trail for accountability and investigation purposes. The other options are not as effective as transaction log review in compensating for the lack of segregation of duties. Background checks are preventive controls that can help screen potential employees for any criminal records or dishonest behavior, but they do not prevent existing employees from abusing their access privileges. User awareness training is a detective control that can help educate users on how to report any suspicious or abnormal activities in the IS environment, but it does not monitor or verify the actions of IS staff. Mandatory holidays are deterrent controls that can discourage IS staff from engaging in fraudulent activities by requiring them to take periodic leave, but they do not prevent or detect such activities when they occur. References: CISA Review Manual (Digital Version), Chapter 3, Section 3.2

The best answer is C. Reviewing key compromise detection activities.

In a PKI, the greatest practical risk in key management is failure to detect and respond when keys are compromised. If compromise is not detected promptly, confidentiality, integrity, authentication, and nonrepudiation can all be undermined. ISACA materials discussing PKI and cryptographic transition stress the importance of certificate revocation, rollout strategies, and careful key management because compromise of keys directly affects trust in the system.

Option D is important, but documentation alone does not prove that compromise can be detected in practice. Option B may help monitoring, but it is narrower than the broader control objective of detecting compromised keys. Option A is not a core audit concern in comparison. From a CISA perspective, the most important focus is whether the organization can detect, contain, and revoke trust when keys are exposed or misused.

References (Official ISACA):

ISACA Journal, Building Resilient Security in the Age of Quantum Computing — discusses PKI key management complexity and certificate revocation as critical control considerations.

A demilitarized zone (DMZ) is a network segment that is separated from the internal network and the external network, such as the internet, by firewalls or other security devices. A DMZ provides an extra layer of security for the organization’s internal network by isolating the servers and services that need to be accessible to external users, such as a file server, from the rest of the network. A DMZ also prevents external users from accessing the internal network directly, as they have to go through two firewalls to reach it. Therefore, setting up a DMZ is an IS auditor’s best recommendation to protect anorganization from attacks when its file server needs to be accessible to external users12.

The other possible options are:

Enforce a secure tunnel connection: This means that the organization requires external users to establish a secure and encrypted connection, such as a virtual private network (VPN), to access its file server. This can provide some level of security and privacy for the data transmission, but it does not protect the file server or the internal network from attacks if the connection is compromised or if the external users are malicious. Therefore, enforcing asecuretunnel connection is not an IS auditor’s best recommendation to protect an organization from attacks when its file server needs to be accessible to external users3.

Enhance internal firewalls: This means that the organization improves the security and performance of its internal firewalls, which are devices that filter and control the network traffic between different segments of the network. This can provide some level of protection for the internal network from unauthorized or malicious access, but it does not protect the file server or the external network from attacks if the file server is exposed to the internet or if the external network is compromised. Therefore, enhancing internal firewalls is not an IS auditor’s best recommendation to protect an organization from attacks when its file server needs to be accessible to external users4.

Implement a secure protocol: This means that the organization uses a secure and standardized protocol, such as Secure File Transfer Protocol (SFTP) or Secure Shell (SSH), to transfer files between its file server and external users. This can provide some level of security and integrity for the data transmission, but it does not protect the file server or the internal network from attacks if the protocol is exploited or if the external users are malicious. Therefore, implementing a secure protocol is not an IS auditor’s best recommendation to protect an organization from attacks when its file server needs to be accessible to external users5. References: 1: What Is a DMZ Network and Why Would You Use It? | Fortinet 2: Demilitarised zone (DMZ) | Cyber.gov.au 3: What Is VPN Tunneling? | Fortinet 4: Firewall - Wikipedia 5: Secure Shell - Wikipedia

Deferring remediation testing until the next audit is justified only when there are significant changes in the audit environment that affect the relevance or validity of the audit observations and recommendations. For example, if there are changes in the business processes, systems, regulations, or risks that require a new audit scope or approach. The other options are not valid justifications for deferring remediation testing, as they do not address the timeliness or quality of the audit follow-up process. The auditor who conducted the audit and agreed with the timeline has left the organization does not affect the responsibility of the audit function to ensure that remediation testing is performed as planned. Management’s planned actions are sufficient given the relative importance of the observations does not guarantee that management will actually implement those actions or that they will be effective in addressing the audit issues. Auditee management has accepted all observations reported by the auditor does not eliminate the need for verification of remediation actions by an independent party. References: CISA Review Manual (Digital Version), Chapter 2, Section 2.4

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

Generalized audit software is a type of computer-assisted audit technique (CAAT) that allows the IS auditor to perform various audit tasks on the data stored in different file formats and databases1. Generalized audit software can help the IS auditor to select a sample for testing that includes the 80 largest client balances and a random sample of the rest, by using functions such as sorting, filtering, stratifying, and randomizing the data23. Generalized audit software can also help the IS auditor to perform other audit procedures on the sample, such as verifying the accuracy, completeness, and validity of the data4.

 The best option for ensuring confidentiality through the use of asymmetric encryption is to encrypt a message with the recipient’s public key (option A). This is because:

Asymmetric encryption, also known as public-key cryptography, is a type of encryption that uses a pair of keys to encrypt and decrypt data. The pair of keys includes a public key, which can be shared with anyone, and a private key, which is kept secret by the owner12.

In asymmetric encryption, the sender uses the recipient’s public key to encrypt the data. The recipient then uses their private key to decrypt the data. This approach allows for secure communication between two parties without the need for both parties to have the same secret key12.

Encrypting a message with the recipient’s public key ensures that only the recipient can decrypt it with their private key. This provides confidentiality, which means that the message is protected from unauthorized access or disclosure12.

Encrypting a message with the sender’s private key (option B) does not ensure confidentiality, but rather authentication, which means that the message can be verified as coming from the sender. This is because anyone can decrypt the message with the sender’s public key, but only the sender can encrypt it with their private key12.

Encrypting a message with the sender’s public key (option C) or the recipient’s private key (option D) does not make sense, as it would render the message unreadable by both parties. This is because neither party has the corresponding key to decrypt it12.

Therefore, the best option for ensuring confidentiality through the use of asymmetric encryption is to encrypt a message with the recipient’s public key (option A), as this ensures that only the recipient can decrypt it with their private key.

Reviewing the last compile date of production programs is the most efficient way to detect unauthorized changes to production programs, as it can quickly identify any discrepancies between the expected and actual dates of program modification. The last compile date is a timestamp that indicates when a program was last compiled or translated from source code to executable code. Any changes to the source code would require a recompilation, which would update the last compile date. The IS auditor can compare the last compile date of production programs with the authorizedchange requests and reports to verify that only approved changes were implemented. The other options are not as efficient as option A, as they are more time-consuming, labor-intensive or error-prone. Manually comparing code in production programs to controlled copies is a method of verifying that the code in production matches the code in a secure repository or library, but it requires access to both versions of code and a tool or technique to compare them line by line. Periodically running and reviewing test data against production programs is a method of verifying that the programs produce the expected outputs and results, but it requires designing, executing and evaluating test cases for each program. Verifying user management approval of modifications is a method of verifying that the changes to production programs were authorized and documented, but it does not ensure that the changes were implemented correctly or accurately. References: CISA Review Manual (Digital Version) , Chapter 4: Information Systems Operations and Business Resilience, Section 4.3: Change Management Practices.

 The primary basis for selecting which IS audits to perform in the coming year is the organizational risk assessment. An organizational risk assessment is a formal process for identifying, evaluating, and controlling risks that may affect the achievement of the organization’sgoals and objectives3. An organizational risk assessment can help IS auditors prioritize and plan their audit activities based on the level of risk exposure and impact of each area or process within the organization. An organizational risk assessment can also help IS auditors align their audit objectives and criteria with the organization’s strategy and performance indicators. Senior management’s request, prior year’s audit findings, and previous audit coverage and scope are also possible bases for selecting which IS audits to perform in the coming year, but not as primary as the organizational risk assessment. These factors are more secondary or supplementary sources of information that can help IS auditors refine or adjust their audit plan based on specific needs or issues identified by management or previous audits. However, thesefactors may not reflect the current or emerging risks that may affect the organization’s operations or performance. References: ISACA CISA Review Manual 27th Edition, page 295

The correct answer is B. To identify material information security vulnerabilities.

The primary purpose of a formal information security audit is to independently evaluate whether security controls are adequate and effective, and to identify material vulnerabilities, weaknesses, or risks that could affect the confidentiality, integrity, and availability of information assets. ISACA states that audit objectives often center on substantiating the existence of internal controls to minimize business risk, and ISACA’s cybersecurity audit guidance describes reviewing gathered data to identify potential security vulnerabilities or risk and documenting findings and recommendations.

Option A is important, but it is more directly related to information security governance and strategy than the primary purpose of a formal audit. Option C is not correct because reducing software licensing cost is a cost-management activity, not the main objective of an information security audit. Option D is also incorrect because monitoring security team productivity is a management function, not the primary purpose of an independent audit.

This question maps mainly to Information Systems Auditing Process because it concerns why an audit is conducted: to provide independent assurance, identify material issues, and support risk-based recommendations.

Evidence of a control’s performance must be verifiable. A missing signature or date means there is no confirmation that the review was actually performed. This undermines the completeness and reliability of the control. Accuracy (A) and content (B) relate to quality but do not address the missing attestation. Industry standards (C) may be relevant, but the auditor’s main concern is that the absence of sign-off creates doubt about whether the control occurred at all. ISACA audit guidance highlights that sufficient and appropriate evidence is required to support the conclusion that a control is operating as designed.

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)

Requiresimplementing controls, whichincur costs.

Risk Transference (Incorrect – C)

Involvesoutsourcing risk(e.g., buying insurance), which hasfinancial costs.

Risk Reduction (Incorrect – D)

Involvesapplying security controls, leading to additional costs.

 A post-implementation review is a process of evaluating the outcome and benefits of a project or a system after it has been implemented. The main purpose of a post-implementation review is to determine to what extent the business requirements are being met by the new system. Therefore, the most likely aspect to be assessed is the results of line processing, which refers to the actual performance and functionality of the system in the operational environment.

According to the ISACA’s Information Security Governance Guidance for Boards of Directors and Executive Management, the highest level of maturity of an information security program is Level 5: Optimized, which means that the program is aligned with the business objectives and strategy, and continuously monitors and improves its performance and effectiveness. A framework is in place to measure risks and track effectiveness, and the program is proactive, adaptive, and innovative.

The other options represent lower levels of maturity:

A training program is in place to promote information security awareness. This is Level 2: Repeatable, which means that the program has some basic policies and procedures, and provides awareness training to employees.

Information security policies and procedures are established. This is Level 3: Defined, which means that the program has formalized policies and procedures, and assigns roles and responsibilities for information security.

The program meets regulatory and compliance requirements. This is Level 4: Managed, which means that the program has established metrics and reporting mechanisms, and complies with relevant laws and regulations.

 Requiring written authorization for all payment transactions is the IS auditor’s best recommendation for a compensating control in an environment where segregation of duties (SoD) cannot be enforced in an accounts payable system. SoD is a principle that requires different individuals or functions to perform different tasks or roles in a business process, such as initiating, approving, recording and reconciling transactions. SoD reduces the risk of errors, fraud and misuse of resources by preventing any single person or function from having excessive or conflicting authority or responsibility. A compensating control is a control that mitigates or reduces the risk associated with the absence or weakness of another control. Requiring written authorization for all payment transactions is a compensating control that provides an independent verification and approval of each transaction before it is processed by the accounts payable system. This control can help to detect and prevent unauthorized, duplicate or erroneous payments, and to ensure compliance with policies and procedures. The other options are not as effective as option A, as they do not provide an independent verification or approval of payment transactions. Restricting payment authorization to senior staff members is a control that limits the number of people who can authorize payments, but it does not prevent them from initiating or processing payments themselves, which could violate SoD. Reconciling payment transactions with invoices is a control that verifies that the payments match the invoices, but it does not prevent unauthorized, duplicate or erroneous payments from being processed by the accounts payable system. Reviewing payment transaction history is a control that monitors and analyzes thepayment transactions after they have been processed by the accounts payable system, but it does not prevent unauthorized, duplicate or erroneous payments from occurring in the first place. References: CISA Review Manual (Digital Version) , Chapter 5: Protection of Information Assets, Section 5.2: Logical Access.

Managing projects as a portfolio allows an organization to oversee and coordinate multiple projects collectively. This approach provides a holistic view, enabling the identification of interdependencies among projects. Recognizing these dependencies is crucial for resource allocation, scheduling, and achieving strategic objectives. While informing users, managing quality, and addressing individual project risks are important, they are typically handled within the scope of each project. The unique advantage of portfolio management lies in its ability to identify and manage relationships and dependencies across multiple projects, ensuring that the portfolio aligns with the organization ' s strategic goals.

The absence of a right-to-audit clause in the outsourcing contract for a cloud service provider would be of greatest concern to an IS auditor1. This clause gives the client the right to audit the service provider’s activities that are relevant to the services being provided1. It is crucial for ensuringthat the service provider is complying with the terms of the contract and meeting the client’s standards for performance, security, and other aspects1. Without this clause, the client may not be able to effectively monitor and manage risks associated with the outsourcing arrangement1.

Materiality is the primary consideration when determining which issues to include in an audit report, as it reflects the significance or importance of the issues to the users of the report. Materiality is a relative concept that depends on the nature, context, and amount of the issues, as well as the expectations and needs of the users. Materiality helps the auditor to prioritize the issues and communicate them clearly and concisely.

The most effective control to maintain segregation of duties in a DevOps environment is A. Enforce approval prior to deployment by a member of the team who has not taken part in the development. Segregation of duties (SoD) is a principle that requires multiple actors to complete a task to reduce the risk of fraud, error, or abuse1. In a DevOps environment, where developers and operators work together to deliver software faster and more reliably, SoD may seem to be incompatible or impractical. However, SoD can still be achieved by implementing controls that ensure that no single person can develop, test, and deploy code without oversight or review2.

Enforcing approval prior to deployment by a member of the team who has not taken part in the development is an effective control that ensures that code changes are verified and validated by a peer before they are released to production. This control can help prevent or detect any unauthorized or malicious modifications, errors, or vulnerabilities in the code, and ensure that the code meets the quality and security standards3. This control can also promote collaboration and feedback among the team members, and improve the transparency and accountability of the software delivery process3.

Comprehensive and Detailed Explanation:

When an auditor finds that the process owner is accepting residual risk beyond the organization’s defined risk appetite, it is not appropriate to accept the action plan or wait until the next committee report.

Escalating to audit management (D) is the correct step. Audit management can then determine whether to escalate further to executive management or the audit committee.

Including in the next report (A) delays timely risk response.

Informing executive management directly (B) bypasses the audit reporting hierarchy.

Accepting the plan (C) would be inappropriate as it ignores risk governance.

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

The best way to mitigate risk to an organization’s network associated with devices permitted under a BYOD policy is to implement a network access control system, as this will allow the organization to monitor, authenticate, and authorize the devices that connect to the network, and to enforce security policies and compliance requirements12. A network access control system can help to prevent unauthorized or compromised devices from accessing sensitive data or resources, and to detect and isolate any potential threats or vulnerabilities34.

 The best environment for copying data and transforming it into a compatible data warehouse format is the staging environment. The staging environment is a temporary area where data from various sources are extracted, transformed, and loaded (ETL) before being moved to the data warehouse. The staging environment allows for data cleansing, validation, integration, and standardization without affecting the source or target systems. The testing environment is not suitable for copying data and transforming it into a compatible data warehouse format, as it is used for verifying and validating the functionality and performance of applications or systems. The replication environment is not suitable for copying data and transforming it into a compatible data warehouse format, as it is used for creating identical copies of data or systems for backup or recovery purposes. The development environment is not suitable for copying data and transforming it into a compatible data warehouse format, as it is used for creating or modifying applications or systems. References:

A continuous integration/continuous development (CI/CD) process helps to reduce software failure risk by enabling smaller incremental changes to the software code, rather than large and infrequent updates12. Smaller incremental changes allow developers to detect and fix errors, bugs, or vulnerabilities more quickly and easily, and to ensure that the software is always in a working state34. Smaller incremental changes also reduce the complexity and uncertainty of the software development process, and improve the quality and reliability of the software product5.

 The greatest concern for an IS auditor when evaluating an organization’s IT strategy and plans is that IT is not engaged in business strategic planning, as this indicates a lack of alignment between IT and business objectives, which could result in inefficient and ineffective use of IT resources and capabilities. The absence of a defined IT security policy, the nondistribution of business strategy meeting minutes, and the inadequate documentation of IT strategic planning are also issues that should be addressed by an IS auditor, but they are not as significant as IT’s noninvolvement in business strategic planning. References: CISA Review Manual (Digital Version), Chapter 3, Section 3.1

The first step when conducting an IT risk assessment is to identify assets to be protected, which include hardware, software, data, processes, people, and facilities that support the business objectives and operations of an organization. Identifying assets to be protected helps to establish the scope and boundaries of the risk assessment, as well as the value and criticality of each asset. Identifying potential threats, assessing vulnerabilities, and evaluating controls in place are subsequent steps in the risk assessment process that depend on the identification of assets to be protected. References: CISA Review Manual (Digital Version), Chapter 2: Governance and Management of IT, Section 2.3: IT Risk Management

Comprehensive and Detailed Explanation:

An IT metrics dashboard provides real-time monitoring and reporting on key IT performance indicators (KPIs), allowing auditors and management to evaluate the effectiveness of IT strategy implementation and execution.

Option A (Benchmarking): Useful for comparisons with peers but not for ongoing execution.

Option B (Maturity models): Assess long-term process maturity, not direct strategy execution.

Option C (Six Sigma): Focuses on process improvement, not IT strategy monitoring.

Option D: Correct — dashboards link strategy to measurable outcomes.

 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

 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.

This means that the IT investments are aligned with the strategic goals and priorities of the organization, and that they deliver value and benefits to the business. Mapping IT investments to specific business objectives can help ensure that the IT investments are relevant, justified, and measurable, and that they support the organization’s mission and vision.

IT investments are implemented and monitored following a system development life cycle (SDLC) is an indication of effective IT project management, but not necessarily of effective IT investment management. The SDLC is a framework that guides the development and implementation of IT systemsand applications, but it does not address the alignment, justification, or measurement of the IT investments.

Key performance indicators (KPIs) are defined for each business requiring IT investment is an indication of effective IT performance management, but not necessarily of effective IT investment management. KPIs are metrics that measure the outcomes and results of IT activities and processes, but they do not address the alignment, justification, or value of the IT investments.

The IT investment budget is significantly below industry benchmarks is not an indication of effective IT investment management, but rather of low IT spending. The IT investment budget should be based on the organization’s needs and capabilities, and not on external comparisons. A low IT investment budget may indicate that the organization is underinvesting in IT, which could limit its potential for growth and innovation.

Periodic recertification of users ensures that only authorized individuals retain access to cloud services and helps identify and revoke access for users who no longer require it. This is a critical control for maintaining security and compliance in a cloud environment.

Classifying Cloud Services (Option A):This is foundational but does not verify ongoing user access.

Centrally Managing Users (Option B):While useful for consistency, it does not assess whether access rights are still valid.

Ensuring Cloud Process Resilience (Option C):This focuses on operational continuity rather than access control.

Periodic recertification aligns with governance practices to ensure access rights remain appropriate over time.

The IS auditor should first determine whether the business impact analysis (BIA) is current with the organization’s structure and context. The BIA is a critical component of the BCP and should reflect the current state of the organization. If the BIA is not up-to-date, it may not accurately reflect the impact of a disruption to the organization’s operations, including the closure of a production plant12.

The correct answer is B. Review the terms and provisions in the contract.

When auditing an outsourced application, the auditor should first understand the contractual responsibilities, service scope, control expectations, reporting requirements, audit rights, compliance obligations, and security commitments. ISACA guidance on outsourcing and third-party assurance emphasizes that contracts are foundational because they define what the service provider is obligated to do and what the customer is entitled to review.

Option A is not first because billing validation is secondary to understanding the service arrangement and obligations.

Option C is incorrect because implementing access rights is a management responsibility, not an audit procedure.

Option D is important, but the auditor must first know whether such reporting is required, how it is defined, and under what timelines, all of which are typically governed by the contract or related agreement.

Therefore, the correct answer is B, because contract review establishes the basis for all further audit work over the outsourced HR application.

References (Official ISACA):

ISACA Journal, Third Party Assurance — highlights the importance of understanding outsourced service arrangements and related assurance expectations.

ISACA Now Blog, The Challenging Task of Auditing Social Media — states that when a function is outsourced, the contract should be reviewed to ensure it specifies required activities and expectations.

The auditor should verify whether a right-to-audit clause exists (B) next, because it is a contractual provision that grants the auditor the right to access and examine the records, systems, and processes of the SaaS provider. A right-to-audit clause is important for ensuring transparency, accountability, and compliance of the SaaS provider with the customer’s requirements and expectations. A right-to-audit clause can also help the auditor to identify and mitigate any risks or issues related to the SaaS agreement12.

Verifying whether IT management monitors the effectiveness of the environment (A) is not the next step, because it is a part of the ongoing monitoring andevaluation process, not the initial walk-through procedures. The auditor should first establish the scope, objectives, and criteria of the audit before assessing the performance and controls of the SaaS provider.

Verifying whether a third-party security attestation exists © is not the next step, because it is not a mandatory requirement for a SaaS agreement. A third-party security attestation is a report or certificate issued by an independent auditor that evaluates and validates the security controls and practices of the SaaS provider. A third-party security attestation can provide assurance and confidence to the customer, but it does not replace or eliminate the need for a right-to-audit clause3.

Verifying whether service level agreements (SLAs) are defined and monitored (D) is not the next step, because it is not directly related to the audit process. SLAs are contractual agreements that specify the quality, availability, and performance standards of the SaaS provider. SLAs are important for measuring and managing the service delivery and customer satisfaction, but they do not grant or guarantee the right to audit4.

 The metric that best indicates the effectiveness of awareness training is the number of users reporting receipt of the email to the information security team. This shows that the users are able to recognize and report a phishing email, which is a common social engineering technique used by attackers to trick users into revealing sensitive information or installing malicious software. The other metrics do not demonstrate a high level of security awareness, as they either ignore, follow, or forward the phishing email, which could expose the organization to potential risks. References: CISA Review Manual, 27th Edition, page 326

Given the large volume of data transactions, continuous monitoring is the best testing strategy for auditing the inventory control process. Continuous monitoring involves the automated review of operational and financial data to identify anomalies or areas of concern12. This approach allows for real-time identification and resolution of issues, making it particularly effective for large organizations with high transaction volumes12.

A maturity model for a technology organization is a tool that measures the progress and capability of the IT function in relation to its goals, processes, and practices. A maturity model can help identify gaps and areas for improvement, as well as benchmark the IT function against industry standards or best practices. One of the key aspects of a maturity model is the definition and clarity of roles and responsibilities for the IT function and its stakeholders. A roles and responsibility matrix, such as a RACI matrix, is a document that clarifies who is responsible, accountable, consulted, and informed for each task or deliverable in a project or process. A roles and responsibility matrix can help avoid confusion, duplication, or omission of work, as well as ensure accountability and communication among the IT function and its customers, partners, and suppliers. Therefore, an IS auditor should focus on reviewing the roles and responsibility matrix when evaluating the maturity model for a technology organization.

A standard operating procedure (SOP) is a document that describes the steps and instructions for performing a routine or repetitive task or process. SOPs are important for ensuring consistency, quality, and compliance in the IT function, but they are not directly related to the maturity model. A service level agreement (SLA) is a contract that defines the expectations and obligations between an IT service provider and its customers. SLAs are important for ensuring customer satisfaction, performance measurement, and dispute resolution in the IT function, but they are not directly related to the maturity model. A business resiliency plan is a document that outlines how an IT function will continue to operate or recover from a disruption or disaster. Business resiliency is important for ensuring availability, reliability, and security in the IT function, but it is not directly related to the maturity model. References: 1: Maturity Models for IT and Technology | Splunk 2: Responsibility assignment matrix - Wikipedia 3: Roles and Responsibilities Matrix - SDLCforms

The greatest concern is regulatory noncompliance arising from cross-border data processing and storage. ISACA guidance on cloud data sovereignty states that when data is stored across multiple jurisdictions, organizations must navigate complex legal and regulatory challenges, including conflicting national laws and cross-border transfer restrictions. This is especially important for financial organizations, which often operate under stricter regulatory obligations regarding customer data, outsourcing, and location of processing.

Option A is correct because the key risk in extending cloud servers into several foreign countries is that the outsourced processing arrangement may violate applicable regulations or create conflicts among data protection, financial-sector, and jurisdictional requirements. ISACA notes that data sovereignty means data is governed by the laws of the country where it is stored, and that organizations must ensure compliance when cloud data spans borders.

Option B is not the greatest concern. Distributed server deployment can introduce integrity challenges, but ISACA’s cross-border cloud guidance emphasizes the legal and governance burden far more directly than integrity degradation as the primary risk.

Option C is incorrect because data classification does not become invalid merely because data is stored overseas. Classification remains an internal governance concept, although handling requirements may change depending on jurisdiction. ISACA specifically recommends maintaining strong data classification systems alongside legal and compliance review for cross-border cloud use.

Option D is also not the greatest concern. Data ownership and responsibility should be clarified contractually, but ISACA identifies legal compliance and jurisdictional conflicts as the dominant governance risk in cross-border cloud environments.

Therefore, A is the best answer because regulatory exposure from cross-border outsourced processing is the most significant concern in this scenario.

SFTP (Secure File Transfer Protocol)is the most secure option for transferring data over the internet, as it encrypts both commands and data, ensuring confidentiality and integrity.

SFTP (Correct Answer – C)

Uses SSH (Secure Shell) for encryption.

Provides authentication and encryption for secure data transfers.

Example:A company uses SFTP to securely transmit payroll files to a third-party processor.

UDP (Incorrect – A)

Faster but lacks encryption and data integrity checks.

HTTP (Incorrect – B)

Transfers data in plaintext and is vulnerable to interception.

RDP (Incorrect – D)

Used for remote desktop access, not secure file transfers.

The best answer is B. To establish the organization’s accountability for the use and protection of personal information.

ISACA privacy guidance emphasizes accountability as a core privacy principle and describes privacy notices as documents that explain how personal information is collected, used, shared, retained, and protected. A privacy notice is fundamentally about transparency and accountability to data subjects regarding the organization’s handling of personal information.

Option A is incorrect because a privacy notice is not primarily a liability shield. Option C is incorrect because a privacy notice may disclose sharing practices, but it is not primarily to obtain blanket approval for sale of personal information. Option D is also incorrect because compliance of controls is a broader privacy governance objective; the notice itself is mainly for transparent disclosure and accountability.

 A network vulnerability assessment is a process of identifying and evaluating the weaknesses and exposures in a network that could be exploited by attackers to compromise the confidentiality, integrity, or availability of the network or its resources. A network vulnerability assessment typically involves scanning the network devices, such as routers, switches, firewalls, servers, and workstations, using automated tools that compare the device configurations, software versions, and patch levels against a database of known vulnerabilities. A network vulnerability assessment can also include manual testing and verification of the network architecture, design, policies, and procedures. One of the main objectives of a network vulnerability assessment is to detect and report any misconfiguration and missing updates in the network devices that could pose a security risk1. Misconfiguration refers to any deviation from the recommended or best practice settings for the network devices, such as weak passwords, open ports, unnecessary services, default accounts, or incorrect permissions. Missing updates refer toany outdated or unsupported software or firmware that has not been patched with the latest security fixes or enhancements from the vendors2. Misconfiguration and missing updates are common sources of network vulnerabilities that can be exploited by attackers to gain unauthorized access, executemalicious code, causedenial of service, or escalate privileges on the network devices3. Therefore, an IS auditor should expect to see misconfiguration and missing updates in a network vulnerability assessment. The other options are less relevant or incorrect because:

B. Malicious software and spyware are not usually detected by a network vulnerability assessment, as they are more related to the content and behavior of the network traffic rather than the configuration and patch level of the network devices. Malicious software and spyware are programs that infect or monitor the network devices or their users for malicious purposes, such as stealing data, displaying ads, or performing remote commands. Malicious software and spyware can be detected by other security tools, such as antivirus software, firewalls, or intrusion detection systems4.

C. Zero-day vulnerabilities are not usually detected by a network vulnerability assessment, as they are unknown or undisclosed vulnerabilities that have not been reported or patched by the vendors or the security community. Zero-day vulnerabilities are rare and difficult to discover, as they require advanced techniques and skills to exploit them. Zero-day vulnerabilities can be detected by other security tools, such as intrusion prevention systems, anomaly detection systems, or artificial intelligence systems5.

D. Security design flaws are not usually detected by a network vulnerability assessment, as they are more related to the logic and functionality of the network rather than the configuration and patch level of the network devices. Security design flaws are errors or weaknesses in the network architecture, design, policies, or procedures that could compromise the security objectives of the network. Securitydesign flaws can be detected by other security methods, such as security reviews, audits, or assessments6. References: Network VulnerabilityAssessment - ISACA, Network Vulnerability Scanning - NIST, Network Vulnerabilities - SANS, Malware - ISACA, Zero-Day Attacks - ISACA, Security Design Principles - NIST

The NEXT step for the IS auditor after noting that an employee who has recently changed roles within the organization still has previous access rights should be to B. determine the reason why access rights have not been revoked. Identifying the cause of this situation is crucial for understanding whether it’s due to oversight, process gaps, or other factors. Once the reason is determined, appropriate corrective actions can be recommended to ensure that access rights are aligned with the employee’s current role and responsibilities1.

Support should be given the greatest consideration when implementing the use of an open-source product, as open-source software may not have the same level of technical support, maintenance, and updates as proprietary software1. Open-source software users may have to rely on the community of developers and users, online forums, or third-party vendors for support, which may not be timely, reliable, or consistent2. Therefore, before implementing an open-source product, users should evaluate the availability and quality of support options, such as documentation, forums, mailing lists, bug trackers, chat channels, etc.3

The greatest concern that the IS auditor should have when reviewing an organization’s security information and event management (SIEM) solution is that the SIEM is decentralized. This is because a decentralized SIEM can pose challenges for collecting, correlating, analyzing and reporting on security events and incidents from multiple sources and locations. A decentralized SIEM can also increase the complexity and cost of maintaining and updating the SIEM components, as well as the risk of inconsistent or incomplete security monitoring and response. The IS auditor should recommend that the organization adopts a centralized or hybrid SIEM architecture that can provide a holistic and integrated view of the security posture and activities across the organization. The other findings are not as concerning as a decentralized SIEM, because they can be addressedby implementing best practices and standards for SIEM reporting and configuration. References: CISA Review Manual (Digital Version)1, Chapter 5, Section 5.2.4

 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:

End-to-end encryption ensures that email content is encrypted during transmission and can only be decrypted by the intended recipient. This approach provides robust protection against interception and unauthorized access.

Encryption of Corporate Network Traffic (Option A):This does not address email confidentiality once the email leaves the corporate network.

Complex User Passwords (Option B):Enhances account security but does not ensure email confidentiality in transit.

Digital Signatures (Option D):Ensures authenticity and integrity but does not encrypt the email content.

Access to production source and object programs is the best way to ensure that effective change management is in place in an IS environment, as it prevents unauthorized or accidental changes to the production code that could affect the functionality, performance, or security of the system. Access to production source and object programs should be restricted to authorized personnel only, and any changes should follow a formal change management process that includes documentation, approval, testing, and review.

The auditor’s best course of action after discovering instances where employees shared license keys to critical pieces of business software is to verify whether the licensing agreement allows shared use. A licensing agreement is a contract between the software provider and the user that defines the terms and conditions of using the software, including the number, type, and scope of licenses granted. Some licensing agreements may allow shared use of license keys among multiple users or devices, while others may prohibit or restrict such use. By verifying the licensing agreement, the auditor can determine whether the employees violated the contract or not, and whether there are any legal or financial risks or implications for the organization.

The other options are not as appropriate as option D, as they may not address the root cause of the issue or provide a comprehensive solution. Recommending the utilization of software licensing monitoring tools may help prevent or detect future instances of license key sharing, but it does not resolve the current situation or ensure compliance with the licensing agreement. Recommending the purchase of additional software license keys may be unnecessary or wasteful if the licensing agreement already allows shared use or if there are unused licenses available. Validating user need for shared software licenses may help identify the reasons or motivations behind license key sharing, but it does not justify or excuse such behavior if it violates the licensing agreement.

 The finding that should be of greatest concern to an IS auditor assessing the effectiveness of an organization’s vulnerability scanning program is that results are not reported to individuals with authority to ensure resolution. This indicates a lack of accountability and communication for vulnerability management, which may result in unresolved or delayed remediation of identified vulnerabilities. This may expose the organization to increased risk of cyberattacks or breaches. The other findings are also concerning, but not as much as this one, because they may affect the completeness, accuracy or timeliness of the vulnerability scanning process, but not necessarily its effectiveness. References:

The first step when developing a DLP solution for a large organization is to conduct a data inventory and classification exercise. This step involves identifying and locating all the data assets that the organization owns, generates, or handles, and assigning them to different categories based on their sensitivity, value, and regulatory requirements1. Data inventory and classification is essential for DLP because it helps to determine the scope and objectives of the DLP solution, as well as the appropriate level of protection and monitoring for each data category2. Data inventory and classification also enables the organization to prioritize its DLP efforts based on the risk and impact of data loss or leakage3.

Option B is not correct because identifying approved data workflows across the enterprise is a subsequent step after conducting data inventory and classification. Data workflows are the processes and channels through which data are created, stored, accessed, shared, or transmitted within or outside the organization4. Identifying approved data workflows helps to define the normal and legitimate use of data, as well as to detect and prevent unauthorized or anomalous data activities5. However, before identifying approved data workflows, the organization needs to know what data it has and how it should be classified.

Option C is not correct because conducting a threat analysis against sensitive data usage is another subsequent step after conducting data inventory and classification. Threat analysis is the process of identifying and assessing the potential sources, methods, and impacts of data loss or leakage incidents. Threat analysis helps to design and implement effective DLP controls and countermeasures based on the risk profile of each data category. However, before conducting threat analysis, the organization needs to know what data it has and how it should be classified.

Option D is not correct because creating the DLP policies and templates is the final step after conducting data inventory and classification, identifying approved data workflows, and conducting threat analysis. DLP policies and templates are the rules and configurations that specify how the DLP solution should monitor, detect, report, and respond to data loss or leakage events. DLP policies and templates should be aligned with the organization’s business needs, regulatory obligations, and risk appetite. However, before creating the DLP policies and templates, the organization needs to know what data it has, how it should be classified, how it should be used, and what threats it faces.

Comprehensive and Detailed Explanation:

The primary purpose of IT capacity management is to ensure that IT infrastructure can meet current and future performance requirements in a cost-effective manner.

Option A is correct because it directly relates to capacity management goals.

Option B (rapid deployment) relates more to change management.

Option C (security concerns) is outside the scope of capacity management.

Option D (reducing cost/time) may be a secondary benefit but not the primary objective.

 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.

 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:

 A disaster recovery plan (DRP) is a set of detailed, documented guidelines that outline a business’ critical assets and explain how the organization will respond to unplanned incidents. Unplanned incidents or disasters typically include cyberattacks, system failures, power outages, natural disasters, equipment failures, or infrastructure damage1. A DRP aims to minimize the impact of a disaster on the business continuity, data integrity, and service delivery of the organization. A DRP also helps the organization recover from a disaster as quickly and efficiently as possible.

A DRP should include steps for obtaining replacement supplies, as this is an essential part of restoring the normal operation of the organization after a disaster. Replacement supplies may include hardware, software, data, network components, office equipment, or other resources that are needed to resume the business functions and processes that were disrupted by the disaster. Obtaining replacement supplies may involve contacting vendors, suppliers, or partners; activating backup or alternative systems; or purchasing or renting new equipment. A DRP should identify the sources, locations, and costs of the replacement supplies, as well as the procedures and responsibilities for acquiring and installing them.

The other three options are not steps that a DRP should include, as they are either part of the pre-disaster planning process or not directly related to the disaster recovery objectives. Assessing and quantifying risk is a step that should be done before creating a DRP, as it helps identify the potential threats and vulnerabilities that could affect the organization and determine the likelihood and impact of each scenario2. Negotiating contracts with disaster planning consultants is also a pre-disaster activity that may help the organization design, implement, test, and maintain a DRP with external expertise and guidance3. Identifying application control requirements is not a step in a DRP, but rather a part of the application development and maintenance process that ensures the quality, security, and reliability of the software applications used by the organization.

Therefore, obtaining replacement supplies is the correct answer.

 To ensure that management concerns are addressed, internal audit should recommend that the data quality team review the data reported to the regulatory body first. This is because this data set is the most relevant and critical to the issue that triggered the enhancement of the data quality program. The data reported to the regulatory body should be accurate, complete, consistent, and timely, as any discrepancies could result in fines, penalties, or reputational damage for the organization.Data with customer personal information is important for data quality, but it is not directly related to the regulatory reporting issue. Data supporting financial statements is important for data quality, but it may not be the same as the data reported to the regulatory body. Data impacting business objectives is important for data quality, but it may not be as urgent or sensitive as the data reported to the regulatory body. References:

The primary area of focus when an organization decides to outsource technical support for its external customers is to align service level agreements (SLAs) with current needs. SLAs are contracts that define the scope, quality, and expectations of the services provided by the vendor, as well as the remedies or penalties for non-compliance. SLAs are essential for ensuring that the outsourced technical support meets the customer’s requirements and satisfaction, as well as the organization’s objectives andstandards. By aligning SLAs with current needs, the organization can specify the key performance indicators (KPIs), metrics, and targets that reflect the desired outcomes and value of the technical support. This can also help to monitor and evaluate the vendor’s performance, identify gaps or issues, and implement corrective actions or improvements.

 The most important thing for an IS auditor to verify when evaluating an organization’s data conversion and infrastructure migration plan is that a rollback plan is included. A rollback plan is a contingency plan that describes the steps and actions to be taken in case the data conversion or infrastructure migration fails or causes unacceptable problems or risks. A rollback plan can help to restore the original data and infrastructure, minimize the impact on the business operations and functions, and ensure the continuity and availability of the IT services. The IS auditor should verify that the rollback plan is feasible, tested, documented, and approved, and that it covers all the possible scenarios and outcomes of the data conversion or infrastructure migration. Theother options are not as important as verifying the rollback plan, because they either do not address the potential failure or disruption of the data conversion or infrastructure migration, or they are partof the normal planning and execution process rather than a contingency plan. References: CISA Review Manual (Digital Version)1, Chapter 4, Section 4.2.3

The best recommendation for an organization that is unable to add new servers on demand in a cost-efficient manner is to build a virtual environment. A virtual environment is a technology that allows multiple virtual machines to run on a single physical server, sharing its resources and capabilities. A virtual environment can help the organization add new servers on demand in a cost-efficient manner by reducing the need for hardware acquisition, maintenance, and power consumption. The other options are not as effective as building a virtual environment, as they do not address the root cause of the problem or provide the same benefits. Increasing the capacity of existing systems is a short-term solution that can help improve the performance and availability of the current servers, but it does not enable the organization to add new servers on demand in a cost-efficient manner. Upgrading hardware to newer technology is a costly solution that can help enhance the functionality and reliability of the servers, but it does not enable the organization to add new servers on demand in a cost-efficient manner. Hiring temporary contract workers for the IT function is an irrelevant solution that can help supplement the IT staff’s skills and knowledge, but it does not enable the organization to add new servers on demand in a cost-efficient manner. References: CISA Review Manual (Digital Version), Chapter 3, Section 3.3.1

 A stateful firewall provides the greatest assurance that outgoing Internet traffic is controlled, as it monitors and filters packets based on their source, destination and connection state. A stateful firewall can prevent unauthorized or malicious traffic from leaving the network, as well as block incoming traffic that does not match an established connection. An intrusion detection system (IDS) can detect and alert on suspicious or anomalous traffic, but it does not block or control it. A security information and event management (SIEM) system can collect and analyze logs and events from various sources, but it does not directly control traffic. A load balancer can distribute traffic among multiple servers, but it does not filter or monitor it. References: CISA ReviewManual (Digital Version), Chapter 6, Section 6.2

When a program release needs to be backed out of production, the changes introduced by that release must be removed from the source code to ensure the system returns to its prior state. This approach ensures that the source code reflects the stable version without the problematic changes.

The best way to reduce the immediate risk associated with using an unsupported version of the software is to segregate the outdated software system from the main network. An unsupported software system may have unpatched vulnerabilities that could be exploited by attackers to compromise the system or access sensitive data. By isolating the system from the rest of the network, the organization can limit the exposure and impact of a potential breach. Verifying all patches have been applied to the outdated software system, closing all unused ports on the outdated software system and monitoring network traffic attempting to reach the outdated software system are also good practices, but they do not address the root cause of the risk, which is the lack of vendor support and updates. References:

The best answer is C. Re-performance of controls.

Under ISACA audit principles, evidence obtained directly by the auditor is generally more reliable than evidence provided by management or gathered indirectly. Re-performance allows the auditor to independently execute the control or procedure and verify whether it works as intended, making it stronger than inquiry, observation, or management attestation.

Option A is the least reliable because inquiry depends on what people say. Option B is stronger than simple inquiry but still relies on management representation. Option D can be useful, but observation only shows what happened at a point in time and may not prove consistent operation. Re-performance gives the auditor the highest level of assurance because the evidence is generated through the auditor’s own independent work.

Periodic review of scheduled jobs is crucial to prevent unauthorized or outdated jobs from running, which could lead to security risks, data inconsistencies, or compliance issues. If the inventory of scheduled jobs is not reviewed periodically (A), it could result in jobs running with incorrect parameters, unauthorized transfers, or failure to decommission obsolete processes.

Other options:

Automated support ticket creation (B) is beneficial but is not as critical as ensuring the overall accuracy and security of job execution.

Restricting access to scheduling changes (C) is a security control, but its absence is not the most pressing concern compared to unreviewed jobs.

Notification alerts to a support group (D) is a good practice but does not replace the need for a formal review process.

Segregation of duties (SoD) is a key internal control that aims to prevent fraud and errors by ensuring that no single individual can perform incompatible or conflicting tasks within a business process. SoD reduces the risk of unauthorized or improper transactions, manipulation of data, or misappropriation of assets.

In the accounts payable department, SoD involves separating the following functions: invoice processing, payment authorization, payment execution, and reconciliation. For example, the person who approves an invoice should not be the same person who issues the payment or reconciles the bank statement.

One of the best ways to ensure appropriate SoD within the accounts payable department is to restrict program functionality according to user security profiles. This means that each user of the accounts payable system should have a unique login and password, and should only have access to the functions that are relevant to their role and responsibilities. For instance, an invoice processor should not be able to approve payments or modify vendor records. This way, the system can enforce SoD and prevent unauthorized or fraudulent activities.

The other options are not as effective as restricting program functionality according to user security profiles. Restricting access to update programs to accounts payable staff only is a general access control measure, but it does not address the SoD issue within the accounts payable department. Including the creator’s user ID as a field in every transaction record created is a useful audit trail feature, but it does not prevent users from performing incompatible functions. Ensuring that audit trails exist for transactions is a detective control that can help identify and investigate any irregularities, but it does not prevent them from occurring in the first place.

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.

The correct answer is D. System uptime was 5% below the average target range.

For an e-commerce organization, system availability is directly tied to revenue, customer trust, transaction processing, and business continuity. If system uptime is below the target range, customers may be unable to browse, order, pay, or receive services. This can cause financial loss, reputational damage, customer dissatisfaction, and breach of service expectations.

Option A is a concern, but a 5% maintenance budget overrun is usually less important than reduced system availability in an e-commerce environment. Option B is not the greatest concern because risk manager approval may be useful, but the more direct business issue is degraded availability. Option C may indicate capacity or performance concerns, but uptime below target is a clearer and more immediate business-impact issue.

This maps to Information Systems Operations and Business Resilience because ISACA’s CISA Exam Content Outline includes IT operations, systems availability, capacity management, incident/problem management, and business resilience under Domain 4.

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 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

 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 best way to facilitate the legal process in the event of an incident is to preserve the chain of custody of the evidence. The chain of custody is a record of who handled, accessed, or modified the evidence, when, where, how, and why. The chain of custody helps to ensure the integrity, authenticity, and admissibility of the evidence in a court of law. The chain of custody also helps to prevent tampering, alteration, or loss of evidence that could compromise the investigation or the prosecution. References:

One of the challenges in developing a SLA for network services is finding performance metrics that can be measured properly and reflect the quality of service expected by the customer. Establishing a well-designed framework for network services is not a challenge, but a good practice. Ensuring that network components are not modified by the client or reducing the number of entry points into the network are security issues, not SLA issues. References: ISACA, CISA Review Manual, 27th Edition, 2018, page 333

The use of open-source software components in IoT devices presents the greatest security risk due to potential vulnerabilities that may exist within the software. These vulnerabilities can be exploited if patches are not applied promptly, and the organization might not have direct control over the software ' s maintenance and security updates. This risk is amplified in critical manufacturing environments where compromised IoT devices can lead to operational disruptions.

Physical Security (Option A):While important, theft of IoT devices generally poses less risk compared to a system-wide compromise due to software vulnerabilities.

Firmware Storage Constraints (Option C):While a limitation, this is a secondary concern compared to exploitable software.

Devices Not Using Wireless Connectivity (Option D):Wired devices are generally more secure, reducing this as a significant concern.

The primary concern is lack of problem management. Recurring processing errors indicate that incidents may be getting handled repeatedly without identifying and eliminating the underlying root cause. ISACA guidance ties problem management to root cause analysis and distinguishes it from incident management, which is primarily focused on restoring service quickly.

Option B is correct because repeated errors usually mean the organization is not effectively analyzing and resolving the underlying cause. ISACA explicitly notes that root cause analysis is essential for both incident and problem-related processes, particularly DSS02 Manage service requests and incidents and DSS03 Manage problems. Repeated issues are a classic sign that problem management is weak or absent.

Option A is not the best answer because incident management is about handling and restoring service for individual events. Even efficient incident response can coexist with recurring incidents if root causes are not addressed. That points more directly to weak problem management than to incident handling alone.

Option C could be relevant if the errors stem from poorly controlled changes, but the question does not mention recent changes. The strongest direct inference from recurring errors is failure to resolve the root cause, which is the purpose of problem management.

Option D is the weakest answer because project management is not the most direct operational control area implicated by recurring production processing errors.

Therefore, B is the best answer because recurring processing errors most strongly suggest that underlying root causes are not being identified and eliminated through effective problem management.

Capability maturity models (CMMs) are frameworks that help organizations assess and improve their processes in various domains, such as software development, project management, service delivery, and cybersecurity1. CMMs define different levels of process maturity, from initial to optimized, and describe the characteristics and best practices of each level. By using CMMs, organizations can benchmark their current processes against a common standard, identify gaps and weaknesses, and implement improvement actions to achieve higher levels of process maturity2. CMMs can also help organizations align their processes with their strategic goals, measure their performance, and increase their efficiency, quality, and customer satisfaction3.

Therefore, the use of CMMs would best enhance a process improvement program, as they provide a systematic and structured approach to evaluate and improve processes based on proven principles and practices. Option C is the correct answer.

Option A is not correct because model-based design notations are graphical or textual languages that help designers specify, visualize, and document the structure and behavior of systems4. While they can be useful for designing and communicating complex systems, they do not directly address the process improvement aspect of a program.

Option B is not correct because balanced scorecard is a strategic management tool that helps organizations translate their vision and mission into measurable objectives and indicators. While it can be useful for monitoring and evaluating the performance of a program, it does not provide specific guidance on how to improve processes.

Option D is not correct because project management methodologies are sets of principles and practices that help organizations plan, execute, and control projects. While they can be useful for managing the scope, schedule, cost, quality, and risk of a program, they do not focus on the process improvement aspect of a program.

The best way to reduce the risk of inaccurate or misleading data proliferating through business intelligence systems is to establish rules for converting data from one format to another, because this ensures that the data quality and integrity are maintained throughout the data transformation process. Data conversion rules define the standards, procedures, and methods for transforming data from different sources and formats into a common format andstructure that can be used by the business intelligence systems12. Implementing data entry controlsfor new and existing applications, implementing a consistent database indexing strategy, and developing a metadata repository to store and access metadata are not the best ways to reduce the risk of inaccurate or misleading dataproliferating through business intelligence systems, becausethey do not address the issue of dataconversion, which is a critical step in the data integration process for business intelligence systems. References: 1: CISA Review Manual (Digital Version), Chapter 4, Section 4.3.3 2: CISA Online Review Course, Module 4, Lesson 3

The best metric to measure the alignment of IT and business strategy is the percentage of enterprise risk assessments that include IT-related risk. This metric indicates how well the organization identifies and manages the IT risks that could affect its strategic objectives and performance. A high percentage of enterprise risk assessments that include IT-related risk shows that the organization considers IT as an integral part of its business strategy and aligns its IT resources and capabilities with its business needs and goals . References: : CISA Review Manual (Digital Version), Chapter 2: Governance and Management of IT, Section 2.2: IT Strategy, page 67 : CISA Online Review Course, Module 2: Governance and Management of IT, Lesson 2.2: IT Strategy

Outsourcing the development of an e-banking solution when in-house technical expertise is not available can significantly reduce start-up costs. This is because the organization can avoid the expenses associated with hiring and training a full-time development team, purchasing necessary hardware and software, and maintaining the system1. While outsourcing can also potentially reduce the risk of system downtime, increase the ability to adapt the system, and provide direct oversight of risks, these benefits are not as immediate or guaranteed as the cost savings123.

The primary role of a control self-assessment (CSA) facilitator is to focus the team on internal controls. A CSA facilitator is a person who guides the CSA process and helps the participants to identify, assess, and improve their internal controls. The facilitator does not conduct interviews, report on weaknesses, or provide solutions, as these are the responsibilities of the participants themselves1.

The other options are incorrect because they are not the primary role of a CSA facilitator. Option A, conduct interviews to gain background information, is a preliminary step that may be done by the facilitator or the participants before the CSA session, but it is not the main purpose of the facilitator. Option C, report on the internal control weaknesses, is an outcome of the CSA process that should be done by the participants who own and operate the controls. Option D, provide solutions for control weaknesses, is also an outcome of the CSA process that should be done by the participants who are in charge of implementing the improvements.

In reviewing the IT strategic plan, the IS auditor should consider whether it identifies the major IT initiatives that are aligned with the organization’s vision, mission, and objectives, and that support the business strategy and priorities12. The major IT initiatives should also be realistic, measurable, and achievable, and should have clear timelines, budgets, and responsibilities34.

An IT balanced scorecard is a framework that translates the IT strategy into measurable objectives, indicators, targets, and initiatives across four perspectives: financial, customer, internal process, and learning and growth. An IT balanced scorecard helps to monitor and evaluate how well the IT function is delivering value to the organization, achieving its strategic goals, and improving its capabilities and competencies. The otheroptions are not the primary uses of an IT balanced scorecard, because they either focus on specific aspects of IT rather than the overall performance, or they are not directly related to the IT strategy. References: CISA Review Manual (Digital Version)1, Chapter 1, Section 1.2.3

The most effective way to identify exfiltration of sensitive data by a malicious insider is to establish behavioral analytics monitoring. Behavioral analytics is the process of analyzing the patterns and anomalies in user behavior to detect and prevent insider threats. Behavioral analytics can help identify unusual or suspicious activities, such as accessing sensitive data at odd hours, transferring large amounts of data to external devices or locations, or using unauthorized applications or protocols. Behavioral analytics can also help correlate data from multiple sources, such as network logs, user profiles, and access rights, to provide a holistic view of user activity and risk.

Data loss prevention (DLP) software is a tool that can help prevent exfiltration of sensitive data by a malicious insider, but it is not the most effective way to identify it. DLP software can block or alert on unauthorized data transfers based on predefined rules and policies, but it may not be able to detect sophisticated or stealthy exfiltration techniques, such as encryption, steganography, or data obfuscation.

Reviewing perimeter firewall logs is a way to identify exfiltration of sensitive data by a malicious insider, but it is not the most effective way. Perimeter firewall logs can show the traffic volume and destination of data transfers, but they may not be able to show the content or context of the data. Perimeter firewall logs may also be overwhelmed by the amount of normal traffic and miss the signals of malicious exfiltration.

Providing ongoing information security awareness training is a way to reduce the risk of exfiltration of sensitive data by a malicious insider, but it is not a way to identify it. Information security awareness training can help educate users on the importance of protecting sensitive data and the consequences of violating policies and regulations, but it may not deter or detect those who are intentionally or maliciously exfiltrating data.

The best control to minimize the risk of unauthorized access to lost company-owned mobile devices is device encryption. Device encryption is a process that transforms data on a device into an unreadable format using a cryptographic key. Device encryption protects the data stored on the device from being accessed by unauthorized parties, even if they bypass the password or PIN protection. Device encryption can also prevent data leakage if the device is disposed of or recycled without proper data sanitization. Password or PIN protection is a basic control that prevents unauthorized access to the device by requiring a secret code or pattern to unlock it. However, password or PIN protection can be easily compromised by brute force attacks, shoulder surfing, or social engineering. Device trackingsoftware is a tool that allows the device owner or administrator to locate, lock, or wipe the device remotely in case of loss or theft. However, device tracking software depends on the device’s network connectivity and GPS functionality, which may not be available or reliable in some situations. Periodic backup is a process that copies the data from the device to another storage location for recovery purposes. Periodic backup can help restore the data in case of loss or damage of the device, but it does not prevent unauthorized access to the data on the device itself. References: CISA ReviewManual (Digital Version), Chapter 5: Protection of Information Assets, Section 5.4: Mobile Devices

 Ensuring that the facts presented in the report are correct is the most important thing for an IS auditor to do during an exit meeting with an auditee. An IS auditor should confirm that the audit findings and observations are accurate, complete, and supported by sufficient evidence, as well as that the auditee understands and agrees with them. This will help to avoid any misunderstandings or disputes later on, as well as to enhance the credibility and quality of the audit report. The other options are less important things for an IS auditor to do during an exit meeting, as they may involve communicating the recommendations to senior management, specifying implementation dates for the recommendations, or requesting input in determining corrective action. References:

The most important factor when planning a network audit is to identify the existing nodes on the network. Nodes are devices or systems that are connected to the network and can communicate with each other. Nodes can include servers, workstations, routers, switches, firewalls, printers, scanners, cameras, etc. Identifying the existing nodes on the network will help the auditor to determine the scope, objectives, and methodology of the audit. It will also help the auditor to assess the network topology, architecture, performance, security, and compliance. References:

In a RAO model, which stands for Responsible, Accountable, Consulted, and Informed, the accountable role must be assigned to only one individual. The accountable role is the person who has the ultimate authority and responsibility for the outcome of the project or task, and who approves or rejects the work done by the responsible role. The accountable role cannot be delegated or shared, as it is essential to have a clear and single point of accountability for each project or task.

The other roles can be assigned to more than one individual:

Responsible. This is the person who does the work or performs the task. There can be multiple responsible roles for different aspects or phases of a project or task, as long as they are coordinated and supervised by the accountable role.

Informed. This is the person who needs to be notified or updated about the progress or results of the project or task. There can be multiple informed roles who have an interest or stake in the project or task, but who do not need to be consulted or involved in the decision-making process.

Consulted. This is the person who provides input, feedback, or advice on the project or task. There can be multiple consulted roles who have expertise or experience relevant to the project or task, but who do not have the authority or responsibility to approve or reject the work done by the responsible role.

 The best way to detect that a distributed denial of service (DDoS) attack is occurring is to use automated monitoring of logs. A DDoS attack disrupts the operations of a server, service, or network byflooding it with unwanted Internet traffic2. Automated monitoring of logs can help pinpoint potentialDDoS attacks by analyzing network traffic patterns, monitoring traffic spikes or other unusual activity, and alertingadministrators or security teams of any anomalies or malicious requests, protocols, or IP blocks3. Automated monitoring of logs can also help identify the source, type, and impact of the DDoS attack, and provide evidence for further investigation or mitigation.

The other options are not as effective as automated monitoring of logs for detecting DDoS attacks. Customer service complaints are an indirect and delayed indicator of a DDoS attack, as they rely onusers reporting problems with accessing a website or service. Customer service complaints may also be caused by other factors unrelated to DDoS attacks, such as server errors or network issues. Server crashes are an extreme and undesirable indicator of a DDoS attack, as they indicate that the server has already been overwhelmed by the attack and has stopped functioning. Server crashes may also result in data loss or corruption, service disruption, or reputational damage. Penetration testing is a proactive and preventive measure for assessing the security posture of a system or network, but it does not detect ongoing DDoS attacks. Penetration testing may involve simulating DDoS attacks to test the resilience or vulnerability of a system or network, but it does not monitor real-time traffic or identify actual attackers.

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

The most important thing to consider before including an audit of IT capacity management in the program is whether the system’s performance poses a significant risk to the organization. IT capacity management is a process that ensures that IT resources are sufficient to meet current and future business needs, and that they are optimized for cost and performance. A poor IT capacity management can result in system slowdowns, outages, failures, or breaches, which can affect the availability, reliability, security, and efficiency of IT services and business processes. Therefore, before conducting an audit of IT capacity management, the auditor should assess the potential impact and likelihood of these risks on the organization’s objectives, reputation, compliance, and customer satisfaction.

Whether system delays result in more frequent use of manual processing (option A) is not the most important thing to consider before including an audit of IT capacity management in the program, as it is only one possible consequence of poor IT capacity management. Manual processing can introduce errors, delays, inefficiencies, and inconsistencies in the data and reports, which can affect the quality and accuracy of financial information. However, manual processing is not the only or the worst outcome of poor IT capacity management; there may be other more severe or frequent risks that need to be considered.

Whether stakeholders are committed to assisting with the audit (option C) is also not the most important thing to consider before including an audit of IT capacity management in the program, as it is a factor that affects the feasibility and effectiveness of the audit, not the necessity or priority of it. Stakeholder commitment is important for ensuring that the auditor has access to relevant information, documents, data, and personnel, as well as for facilitating communication, collaboration, and feedback during the audit process. However, stakeholder commitment is not a sufficient reason to conduct an audit of IT capacity management; there must be a clear risk-based rationale for selecting this area for audit.

Whether internal auditors have the required skills to perform the audit (option D) is also not the most important thing to consider before including an audit of IT capacity management in the program, as it is a factor that affects the quality and credibility of the audit, not the urgency or importance of it. Internal auditors should have the appropriate knowledge, skills, and experience to perform an audit of IT capacity management, which may include technical, business, analytical, and communication skills. However, internal auditors can also acquire or supplement these skills through training, coaching, consulting, or outsourcing. Therefore, internal auditors’ skills are not a decisive factor for choosing this area for audit.

Therefore, option B is the correct answer.

The issue seems to stem from a breakdown in the workflow or process for handling assets that are due for destruction12. By examining the workflow, the IS auditor can identify where the process failed, such as why the vendor was not notified about the hard drives12. This could involve reviewing procedures for inventory management, communication with vendors, and tracking of assets due for destruction12. The findings can then be used to improve the workflow and prevent similar issues in the future12.

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.

To reduce false positive alerts, it is essential to carefully configure a limited set of rules tailored to the organization ' s specific data loss prevention needs. This ensures that the DLP tool accurately identifies true positives and reduces the occurrence of false alarms.

 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

The correct answer is A. Make an image of the hard drive for investigation and save the original drive in a secure place.

In a forensic investigation, the original evidence must be preserved. The investigator should create a forensic image of the hard drive and perform the investigation on the copy, not the original. This protects the integrity of the original evidence and supports admissibility, reliability, and repeatability of the investigation.

Option B is incorrect because investigating the original hard drive may alter metadata, file access times, temporary files, or system state. Option C is inappropriate because the user should not be responsible for copying potential evidence. That would weaken evidence reliability and chain of custody. Option D is risky because restarting the computer may change evidence. Depending on the case, volatile evidence may need to be captured before shutdown.

ISACA’s glossary defines chain of custody as the process for maintaining and documenting evidence handling, including who handled the evidence and when. ISACA also defines hashing as a cryptographic process used to support integrity. These concepts support preserving the original evidence and working from a verified forensic image.

The correct answer is B. Determine if project goals were met as expected.

The primary purpose of a post-implementation review is to determine whether the project achieved its intended objectives, delivered the expected business value, met requirements, and produced the expected benefits. For a critical IT project, the most important audit focus is not only whether the project was delivered on time or within budget, but whether it actually achieved what the organization expected from it.

ISACA’s CISA Exam Content Outline specifically includes Post-implementation Review under Domain 3 and states that CISA tasks include conducting post-implementation reviews to determine whether project deliverables, controls, and requirements are met.

Option A is useful but not the primary focus. Business representation on the steering committee supports good governance, but it does not prove that the project achieved its objectives.

Option C is also important, but on-time and on-budget delivery does not necessarily mean project success. A project can be delivered on time and within budget but still fail to meet business requirements.

Option D is evidence of formal project closure, but stakeholder signoff alone does not provide enough assurance that the project goals and expected benefits were achieved.

ISACA also notes that benefit realization is measured after implementation and that a post-implementation review is usually recommended to quantify actual benefits from a program.

The best recommendation is database segmentation. If liability depends on the number of individuals whose PII is exposed, the organization should reduce the amount of data that could be compromised in any single breach event. Segmenting databases or separating sensitive data domains limits blast radius and can reduce the number of records exposed in a single incident. ISACA guidance supports isolating high-value assets and tightening internal controls as a way to reduce exposure and improve resilience.

Option A is correct because segmentation limits concentration risk. Instead of keeping all customer data in one broadly exposed logical store, segmentation helps confine access and reduce how many records a single compromise can reach. This directly supports limiting breach impact and, in this case, potential liability tied to the number of affected individuals. This conclusion is an inference from ISACA’s risk-reduction principles around isolation, exposure control, and documenting exposure.

Option B is incorrect because database normalization improves data structure and reduces redundancy; it is not primarily a breach-liability reduction control.

Option C is incorrect because database harmonization is about consistency or integration across datasets, not limiting exposure in a breach.

Option D is incorrect because database optimization focuses on performance and efficiency, not on minimizing the number of PII records exposed in a security incident.

Therefore, A is the best answer because segmentation is the option that most directly reduces the scope of exposure in a breach and therefore helps limit liability based on affected individuals.

 Write access to production program libraries presents the greatest risk when granted to a new member of the system development staff. Production program libraries contain executable code that runs on live systems and supports critical business functions. Write access allows a user to modify or delete existing programs, or add new programs to the library. If a user were to make unauthorized or erroneous changes to production programs, it could cause serious disruptions, errors, or security breaches in the organization’s operations. Therefore, writeaccess to production program libraries should be restricted to authorized personnel only, and subject to strict change management controls. 

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:

The correct answer is A. It acts as a measuring tool and progress indicator.

The primary benefit of periodic maturity model assessments is that they allow the organization to measure its current level of capability or maturity and compare progress over time. This helps management understand whether processes are improving, staying the same, or declining.

ISACA explains that COBIT performance management evaluates how well governance and management systems work and how they can be improved to achieve target levels of process and practice capability and maturity. ISACA also describes maturity models as methods based on measuring progress through predefined levels of increasing maturity.

Option B is not the best answer because a maturity assessment may identify weaknesses, but it does not automatically fix them. Option C is related, because maturity assessment results may support an improvement plan, but execution of the plan is not the primary benefit of the assessment itself. Option D is too broad; maturity assessments may support consistency and improvement, but their primary value is measurement and progress tracking.

This question maps mainly to Governance and Management of IT, because maturity assessment supports governance, performance monitoring, process improvement, and management oversight.

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:

 The record-locking option of a database management system (DBMS) serves to eliminate the risk of concurrent updates to a record by different users or transactions. Record locking is a technique of preventing simultaneous access to data in a database, to prevent inconsistent results1. For example, if two bank clerks try to update the same bank account for two different transactions, record locking can ensure that only one clerk can modify the record at a time, while the other has to wait until the lock is released. This way, the record will reflect both transactions correctly and avoid data corruption.

Record locking does not serve to allow database administrators (DBAs) to record the activities of users. This is a function of auditing or logging, which can track the actions performed by users on the database2. Record locking does not affect the ability of DBAs to monitor or audit user activities.

Record locking does not serve to restrict users from changing certain values within records. This is a function of access control or authorization, which can enforce rules or policies on what data users can view or modify2. Record locking does not affect the permissions or privileges of users on the database.

Record locking does not serve to allow users to lock others out of their files. This is a function of encryption or password protection, which can secure files from unauthorized access or modification3. Record locking does not affect the security or confidentiality of files on the database.

The correct answer is D. Establish a global IT risk scoring criteria.

When business units use different risk methods, their risk scores are not comparable. One unit’s “high” risk may not mean the same thing as another unit’s “high” risk. The organization first needs a common risk scoring method so IT risks can be measured, compared, aggregated, and reported consistently across the enterprise.

Option A is not the best first approach because a weighted score is only useful after the organization has consistent scoring criteria. Option B is not appropriate because choosing the highest-rated risk may overstate overall risk appetite and may be based on inconsistent rating methods. Option C is also inappropriate because averaging inconsistent risk scores can produce misleading results.

ISACA’s glossary defines risk appetite as the amount of risk an entity is prepared to accept when pursuing its objectives. ISACA also discusses risk appetite in terms of identifying risk the organization is or is not willing to accept in relation to its values, digital strategy, stakeholder impact, and required actions.

This maps to Governance and Management of IT because risk appetite, IT risk management, risk reporting, and governance decision-making are Domain 2 topics in the CISA Exam Content Outline.

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 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 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.

File transfer protocol (FTP) is a service that allows users to transfer files between computers over a network. If enabled within firewall rules, FTP would present the greatest risk, as it can expose sensitive data to unauthorized access, modification, or deletion. FTP does not provide encryption or authentication, which makes it vulnerable to eavesdropping, spoofing, and tampering attacks. Simple mail transfer protocol (SMTP), simple object access protocol (SOAP), and hypertext transfer protocol (HTTP) are also services that can be used to exchange data over a network, but they have more security features than FTP, such as encryption, authentication, or validation. References: CISA Review Manual (Digital Version)

Low-priority jobs typically involve non-critical processes or tasks that do not immediately impact business operations. The best approach to handling such jobs is to schedule them subject to resource availability. This ensures that high-priority tasks can access resources when needed without being affected by the execution of low-priority tasks.

Avoiding Low-Priority Jobs (Option A)is not feasible because even low-priority tasks may be necessary for maintenance or support activities.

Including Major Functions in Low-Priority Jobs (Option B)contradicts the classification of " low-priority " because major functions are usually critical.

Allocating Optimal Resources to Low-Priority Jobs (Option C)is inefficient as resources should primarily be allocated to high-priority tasks.

Scheduling based on resource availability optimizes the use of resources, avoids unnecessary delays in high-priority activities, and ensures that low-priority tasks are executed without disrupting overall operations. This aligns with best practices in IT resource management and scheduling.

The expected costs for recovering the business would be used when performing a business impact analysis (BIA). A BIA is a process of identifying and evaluating the potential effects ofdisruptions to critical business functions or processes. A BIA helps to determine the recovery priorities, strategies, and resources needed to resume normal operations after a disruption. One of the key outputs of a BIA is an estimate of the financial losses or costs associated with different types of disruptions, such as lost revenue, increased expenses, contractual penalties, or regulatory fines.

 Capacity management tools are primarily used to ensure that available resources are used efficiently and effectively to meet the current and future demands of the business. Capacity management tools can help monitor, analyze and optimize the performance and utilization of IT resources such as CPU, memory, disk, network, etc. The other options are not the primary purpose of capacity management tools, although they may be related or derived from them. References:

 The best way to help ensure new IT implementations align with enterprise architecture (EA) principles and requirements is to conduct EA reviews as part of the change advisory board (CAB). A CAB is a committee that evaluates and authorizes changes to IT services, such as new IT implementations. By conducting EA reviews as part of the CAB process, the organization can ensure that the proposed changes are consistent with the EA vision, goals, standards, and guidelines. This can help avoid potential conflicts, risks, or inefficiencies that may arise from misaligned IT implementations. Additionally, EA reviews can help identify opportunities for improvement, optimization, or innovation in the IT services.

The other options are not the best ways to help ensure new IT implementations align with EA principles and requirements. Documenting the security view as part of the EA is important, but it does not guarantee that new IT implementations will follow the security requirements or best practices. Considering stakeholder concerns when defining the EA is also essential, but it does not ensure that new IT implementations will meet the stakeholder expectations or needs. Performing mandatory post-implementation reviews of IT implementations is a good practice, but it does not prevent potential issues or problems that may arise from misaligned IT implementations.

 The auditor’s best course of action after a security breach in which a hacker exploited a well-known vulnerability in the domain controller is to determine if the logs were monitored. Log monitoring is an essential control for detecting and responding to security incidents, especially when known vulnerabilities exist in the system. The auditor should assess if the logs were properly configured, collected, reviewed, analyzed, and acted upon by the responsible parties. Updating patches, monitoring network traffic, and classifying domain controllers for high availability are also important controls, but they are not directly related to the detection and response of the security breach. References:

The first thing that should be done before allowing users to connect personal devices to the corporate network is to implement an acceptable use policy. An acceptable use policy is a document that defines the rules and guidelines for using personal devices on the corporate network, such as security requirements, access rights, responsibilities, and consequences. An acceptable use policy can help to protect the organization from potential risks such as data leakage, malware infection, or legal liability. The other options are not as important as implementing an acceptable use policy, as they do not establish the boundaries and expectations for using personal devices on the corporate network. References: CISA Review Manual, 27th Edition, page 318
