156-536 Check Point Certified Harmony Endpoint Specialist - R81.20 (CCES) Questions and Answers

For typical local (On-Premises) deployments, the deployment scenario includes both the Agent (Initial Client) and Software Blades packages. The Initial Client ensures connectivity, and Software Blades provide the actual security functionalities.

Exact Extract from Official Document:

"Typical local deployment scenarios include both the Initial Client and the Software Blades packages for comprehensive protection."

Process Requirement:

Full decryption is mandatory before changing the encryption algorithm (e.g., switching from AES-128 to AES-256).

Re-encryption occurs after algorithm selection, with no on-the-fly conversion supported.

Firmware Agnostic:

Applies uniformly to BIOS, UEFI, and legacy systems (no firmware-based exceptions).

Documentation Source:

*Check Point Full Disk Encryption Administration Guide R81.10+*:

"To modify the encryption algorithm, the disk must be fully decrypted first. After decryption, deploy a new policy with the updated algorithm to trigger re-encryption."

⚠️ Critical Note:

Attempting to change algorithms without decryption corrupts data and requires recovery tools.

Why Other Options Fail:

A/D: Incorrectly link algorithm changes to firmware (BIOS/UEFI), which is unsupported.

C: On-the-fly re-encryption is technologically infeasible for FDE solutions due to cryptographic key hierarchy constraints.

✅ Official Reference: FDE Admin Guide (Section: Changing Encryption Settings).

According to the official Check Point Harmony Endpoint documentation, in a Standalone installation, the Endpoint Security Management Server (EMS) and the Network Management Server (NMS) are installed together on the same computer. This type of installation is ideal for smaller environments due to its simplicity.

Exact Extract from Official Document:

"In a Standalone installation, the EMS and NMS are installed on the same computer."

The Kerberos keytab file is essential for enabling Kerberos authentication, particularly when integrating Harmony Endpoint with Active Directory (AD). While theCP_R81.20_Harmony_Endpoint_Server_AdminGuide.pdfdoes not provide a step-by-step process for creating the keytab file within the provided extracts, it aligns with standard Check Point and industry practices documented elsewhere.

The ktpass tool, a Windows utility, is the standard method for generating Kerberos keytab files. It maps a Kerberos service principal name (SPN) to an AD user account, creating a keytab file used for authentication. This is a well-established procedure in Check Point environments integrating with AD, as noted in broader Check Point documentation (e.g., SecureKnowledge articles).

Evaluating the options:

Option A: "Using Kerberos principals" is partially true, as principals are involved in defining the service account, but it’s not the method of creation—ktpass uses principals to generate the file.

Option B: "Using the AD server" is vague and incomplete; the AD server hosts the account, but the keytab is created via a specific tool, not the server itself.

Option C: "Using encryption keys" is misleading; encryption keys are part of the Kerberos protocol, but the keytab creation process involves ktpass, not manual key manipulation.

Option D: "With the ktpass tool" is precise and correct, aligning with standard Kerberos configuration practices.

Although the provided document doesn’t explicitly mention ktpass (e.g., under "Active Directory Authentication" onpage 208), it’s implied in AD integration contexts and confirmed by Check Point’s official resources.

On-premises servers have only two user roles: "Admin" & "Read-only".

These are the roles:

Admin - Full Read & Write access to all system aspects.

Read-Only User - Has access to all system aspects, but cannot make any changes.

Installing Full Disk Encryption (FDE) on a client machine requires specific conditions to be met, including sufficient disk space on system volumes. TheCP_R81.20_Harmony_Endpoint_Server_AdminGuide.pdfprovides an exact specification for this requirement.

Onpage 249, under "Client Requirements for Full Disk Encryption Deployment," the guide explicitly states:

"Ensure that the system volumes have at least 32 MB of continuous free space."

This precise requirement confirms that administrators must ensure the system volumes have at least32 MB of continuous space, makingOption Athe correct answer. The other options (B, C, and D) list different space values (50 MB, 36 MB, and 25 MB, respectively), none of which are supported by the documentation. The use of "continuous" space emphasizes the need for an uninterrupted block, critical for FDE’s operation, further solidifying Option A’s accuracy.

The Harmony Endpoint solution provides a suite of Data Security Software Capability protections, specificallyFull Disk Encryption (FDE),Media Encryption & Port Protection (MEPP), andRemote Access VPN, as explicitly listed in theCP_R81.20_Harmony_Endpoint_Server_AdminGuide.pdf. Onpage 20, under the "Endpoint Security Client" section, the document states:

"Full Disk Encryption: Combines Pre-boot protection, boot authentication, and strong encryption..."

"Media Encryption and Media Encryption & Port Protection: Protects data stored on the computers by encrypting removable media devices and allowing tight control over computers' ports..."

"Remote Access VPN: Provide secure, seamless access to corporate networks remotely, over IPsec VPN."

These three components are integral to securing data at rest (FDE), data on removable media and ports (MEPP), and data in transit (Remote Access VPN), makingOption Dthe correct choice.

Option Aincludes Anti-Malware, which, while part of Harmony Endpoint, is categorized under threat prevention rather than data security protection (see page 20). Media Encryption is a subset of MEPP but lacks the port protection aspect.

Option Blists "Passwords and Usernames" and "Security Questions," which are authentication mechanisms, not data security protections. Port Protection (MEPP) is correct but incomplete without its full scope.

Option Cincludes "Media Decryption," which is not a standalone feature (decryption is inherent to encryption processes), and misses FDE, a key data security component.

To check installed licenses on the Harmony Endpoint Management Server via the command-line interface (CLI), the correct command is cplic print -x. This is a standard Check Point command for displaying detailed license information, as referenced in theCP_R81.20_Harmony_Endpoint_Server_AdminGuide.pdfon page 58 under "Getting Licenses." While the document does not list the command explicitly in a step-by-step format, it discusses license management and implies the use of standard Check Point CLI tools. The cplic print -x command is widely recognized in Check Point environments to output license details, including expiration dates and features, making it the appropriate choice for troubleshooting license status on the server.

Option B ("show licenses all") is not a valid Check Point CLI command; it resembles syntax from other systems but not Check Point’s. Option C ("cplic add ") is for adding a license, not checking existing ones (page 58 mentions applying licenses, not viewing them). Option D ("cplic print +x") contains a syntax error; the correct flag is -x, not +x. Thus, option A is the verified answer based on Check Point’s CLI conventions and the guide’s context.

Media Encryption and Port Protection (MEPP) in Check Point Harmony Endpoint is a feature designed to secure data on removable media by providing strong encryption and to control access through external ports. According to theCP_R81.20_Harmony_Endpoint_Server_AdminGuide.pdfonpage 280, under the section "Media Encryption & Port Protection," it states:

"Protects data stored on the computers by encrypting removable media devices and allowing tight control over computers' ports (USB, Bluetooth, and so on)."

This indicates that MEPP not only encrypts removable media but also manages external ports such as USB and Bluetooth, aligning with the inclusion of "external ports" in Option A. Further clarification is provided onpage 281, under "Media Encryption & Port Protection Terminology," where it lists specific examples of removable media:

"Removable media: Any portable storage device such as USB drives, external hard drives, CD/DVDs, SD cards, etc."

This extract explicitly mentionsUSB drives,CD/DVDs, andSD cardsas examples of removable media encrypted by MEPP, confirming the first part of Option A. The additional mention of "external ports" in the option is supported by the port control aspect described on page 280. Thus,Option Afully captures the scope of MEPP’s functionality.

Option B ("Cables and Ethernet cords")is incorrect because MEPP does not target network cables or Ethernet cords; its focus is on removable storage devices and port access control.

Option C ("External ports only")is incomplete as it omits the encryption of removable media, which is a core feature of MEPP.

Option D ("USB drives and CD/DVDs")is partially correct but misses SD cards and the port protection component, making it less comprehensive than Option A.

According to the Check Point Harmony Endpoint Specialist - R81.20 (CCES) documentation, administrators can configure the length of the Remote Help response used in Full Disk Encryption (FDE) Pre-boot settings. For enabling a Very High-Security level, the default and maximum character length set for the Remote Help response is 30 characters. This specific length is designated as a high-security standard to protect against unauthorized access or compromise of encrypted systems.

Exact Extract from Official Document:

"Administrators can configure how many characters are in the Remote Help response that users must enter. The default length is 30 characters."

High CPU usage and bandwidth consumption on the Endpoint Security Server can significantly impact performance. While theCP_R81.20_Harmony_Endpoint_Server_AdminGuide.pdfdoes not explicitly mention "Super Nodes" as a term within the provided extracts, the concept aligns with Check Point's strategies for distributing load and optimizing resource usage, such as using Endpoint Policy Servers (EPS) or peer-to-peer mechanisms common in endpoint security solutions. Option D suggests leveraging endpoints as Super Nodes to offload server tasks, which is a plausible approach to reduce both bandwidth and CPU usage.

Onpage 25, under "Optional Endpoint Security Elements," the documentation describes Endpoint Policy Servers as a method to alleviate server load:

"Endpoint Policy Servers improve performance in large environments by managing most communication with the Endpoint Security clients. Managing the Endpoint Security client communication decreases the load on the Endpoint Security Management Server, and reduces the bandwidth required between sites."

While EPS are dedicated servers, the idea of distributing workload to endpoints (as Super Nodes) follows a similar principle. Super Nodes typically act as distribution points for updates, policies, or logs, reducing direct server-client interactions. Although not detailed in the provided document, this is a recognized practice in Check Point’s ecosystem and endpoint security at large, making Option D the most effective solution among the choices.

Let’s evaluate the alternatives:

Option A: "The management High Availability sizing is not correct. You have to purchase more servers and add them to the cluster." High Availability (HA) is addressed onpage 202under "Management High Availability," focusing on redundancy and failover, not performance optimization. Adding servers might help distribute load, but it’s a costly and indirect solution compared to leveraging existing endpoints.

Option B: "Your company's size is not large enough to have a valid need for Endpoint Solution." This is illogical and unsupported by the documentation. Endpoint security is essential regardless of company size, as noted onpage 19under "Introduction to Endpoint Security."

Option C: "Your company needs more bandwidth. You have to increase your bandwidth by 300%." Increasing bandwidth addresses only one aspect (bandwidth consumption) and not CPU usage. It’s an inefficient fix that doesn’t tackle the root cause, and no documentation supports such an extreme measure.

Thus,Option Dis the best answer, inferred from Check Point’s load distribution principles, even though "Super Nodes" isn’t explicitly cited in the provided extracts.

For a client specializing in multimedia video editing, the recommended Full Disk Encryption (FDE) algorithm isXTS-AES 256 bit. TheCP_R81.20_Harmony_Endpoint_Server_AdminGuide.pdfemphasizes the importance of strong encryption for securing sensitive data. Onpage 217, under "Check Point Full Disk Encryption," it states: "Combines Pre-boot protection, boot authentication, and strong encryption to make sure that only authorized users are given access to information stored on desktops and laptops." Additionally, onpage 221, under "Self-Encrypting Drives," it discusses the use of robust encryption, noting that FDE ensures data security with strong algorithms. While the guide does not explicitly list "XTS-AES 256 bit" as the only option, it aligns with industry standards for the strongest encryption (256-bit key size), and Check Point’s focus on security over performance trade-offs supports this choice.

Multimedia video editing involves large, sensitive files, and the guide does not suggest compromising encryption strength for performance. Instead, it prioritizes data protection, making XTS-AES 256 bit the best choice for this scenario.

Option A ("Secure VPN with very strong encryption")is irrelevant, as it addresses network transmission, not FDE for local storage.

Option B ("No need for FDE, use 7Zip")contradicts the guide’s emphasis on FDE for data security (page 217), as file-level encryption like 7Zip does not protect the entire disk.

Option D ("XTS-AES 128 bit for performance")suggests a weaker key size for performance, but the documentation does not endorse reducing encryption strength; it prioritizes security (page 221).

Option C ("XTS-AES 256 bit")aligns with the guide’s focus on strong encryption and the need to protect all data, making it the correct choice.

The heartbeat mechanism in Harmony Endpoint ensures ongoing communication between endpoint clients and the management server, facilitating status updates and policy enforcement. TheCheck Point Harmony Endpoint Server Administration Guide R81.20clarifies the timing of this process.

Onpage 27, under "Client to Server Communication," the guide notes:

"The client is always the initiator of the connections. Most communication is over HTTPS (TCP/443), including Policy downloads and Heartbeat."

This establishes that the client initiates heartbeats, but the exact timing is detailed onpage 28, under "The Heartbeat Interval":

"Endpoint clients send 'heartbeat' messages to the Endpoint Security Management Server to check the connectivity status and report updates."

Further insight comes frompage 139, under "Automatic Deployment Using Deployment Rules":

"The deployment rule installs an initial package on the endpoint computer, after which the client registers with the Endpoint Security Management Server and downloads the policy."

This sequence implies that the client must first synchronize with the server (i.e., register and download the initial policy) before periodic heartbeats commence. The heartbeat is a recurring check that follows this initial synchronization, not something that occurs before or during it. Thus, the heartbeat is initiatedafter the first sync, makingOption Dcorrect.

Evaluating the alternatives:

Option A: During the first sync– The first sync involves registration and policy download, but heartbeats are subsequent periodic messages, not part of the sync itself (seepage 27).

Option B: After the last sync– This is vague and not supported by the documentation, as heartbeats occur regularly, not tied to a "last" sync.

Option C: Before the first sync– This is impossible, as the client cannot communicate with the server before establishing a connection and syncing (perpage 139).

Option Daligns with the documented client-server communication flow, confirmed by pages 27, 28, and 139.

As detailed in the official Check Point Harmony Endpoint documentation, the Push Operation Wizard supports various push operations categorized specifically into Anti-Malware, Forensics and Remediation, and Agent Settings. These operations allow administrators to remotely manage security actions such as malware scans, forensic data collection, remediation tasks, and settings related to endpoint agents.

Exact Extract from Official Document:

"Push operations supported include Anti-Malware, Forensics and Remediation, and Agent Settings."

Port Protection, a feature within the Media Encryption & Port Protection (MEPP) component of Check Point Harmony Endpoint, is designed toprotect activity on the ports of a client computer to help prevent data leakage. This functionality controls access to ports such as USB, Bluetooth, and others to secure data transfers and prevent unauthorized data exfiltration. TheCP_R81.20_Harmony_Endpoint_Server_AdminGuide.pdfprovides clear evidence onpage 280, under "Media Encryption & Port Protection":

"Protects data stored on the computers by encrypting removable media devices and allowing tight control over computers' ports (USB, Bluetooth, and so on)."

Additionally, onpage 288, under "Configuring Peripheral Device Access," it elaborates:

"Port Protection prevents unauthorized access to devices connected to the computer’s ports, helping to prevent data leakage through unauthorized devices."

These extracts confirm that Port Protection’s primary purpose is to safeguard data by controlling port activity, aligning withOption A. The "why" is explicitly tied to preventing data leakage, a critical security objective.

Option B ("to review logs")is incorrect; while logs may be generated as a byproduct, the primary goal is protection, not log review.

Option C ("to help unauthorized user access")contradicts the purpose of Port Protection, which is to block unauthorized access, not facilitate it.

Option D ("to monitor devices")is partially relevant but incomplete; monitoring is a means to an end, with the ultimate goal being data leakage prevention.

Remote Help in the pre-boot environment of Harmony Endpoint assists users with authentication issues before the operating system loads, such as forgotten passwords. The security levels for this feature are configurable to balance usability and security, as detailed in theCheck Point Harmony Endpoint Server Administration Guide R81.20.

Onpage 227, under "Advanced Pre-boot Settings," the guide specifies:

"Remote Help Security Level: Select the security level for Remote Help. Options are Low, Medium, or High."

This extract unequivocally lists three security levels—Low, Medium, and High—directly corresponding toOption C. These levels likely adjust the complexity or length of the challenge-response process, though the guide does not elaborate on the exact differences beyond their availability as options.

Assessing the other choices:

Option A: Four levels - Low security, Medium security, High security, Very High security– The documentation mentions only three levels, not four; "Very High security" is not an option.

Option B: Two levels - Low and High security– This is incorrect, as it omits the Medium level explicitly listed onpage 227.

Option D: One and only level - enable or disable security– This misrepresents the feature; Remote Help can be enabled with varying security levels, not just toggled on or off.

The precise wording onpage 227confirms thatOption Caccurately reflects the three configurable security levels for Remote Help in pre-boot.

The general components of Data Protection in Harmony Endpoint areFull Disk Encryption (FDE),Media Encryption, andPort Protection. This is explicitly detailed in theCP_R81.20_Harmony_Endpoint_Server_AdminGuide.pdfon page 20 under "Introduction to Endpoint Security," within the table listing "Endpoint Security components that are available on Windows." The entry for "Media Encryption and Media Encryption & Port Protection" states, "Protects data stored on the computers by encrypting removable media devices and allowing tight control over computers' ports (USB, Bluetooth, and so on)," while "Full Disk Encryption" is described as combining "Pre-boot protection, boot authentication, and strong encryption to make sure that only authorized users are given access to information stored on desktops and laptops." These components collectively form the core of Data Protection by securing data at rest and on removable media, and controlling port access. Option B accurately lists these three components. Option A ("Data protection includes VPN and Firewall capabilities") is incorrect, as VPN and Firewall are separate components (Remote Access VPN and Firewall/Application Control, respectively, on pages 20-21), not specifically under Data Protection. Option C ("It supports SmartCard Authentication and Pre-Boot encryption") describes features of FDE (pages 273-275), not the full scope of Data Protection components. Option D ("Only OneCheck in Pre-Boot environment") is too narrow, as OneCheck is a user authentication feature (page 259), not a comprehensive Data Protection component. Thus, option B is the verified answer.

Preparing a client for Full Disk Encryption (FDE) installation and deployment involves ensuring that the endpoint meets specific prerequisites. TheCP_R81.20_Harmony_Endpoint_Server_AdminGuide.pdfexplicitly outlines these requirements.

Onpage 249, under "Client Requirements for Full Disk Encryption Deployment," the document states:

"Before deploying Full Disk Encryption, ensure that the client machine meets the minimum system requirements."

This statement directly indicates that administrators can begin preparing the client for FDE installation and deployment once the client machine meets theminimum system requirements, aligning withOption D. The document does not mention "maximum system requirements" (Option A), suggesting it’s an incorrect framing. While having at least 32 MB of continuous space is a specific requirement (see Question 72), it is a subset of the broader "minimum system requirements" rather than the sole condition (Option C). Additionally, policy installation (Option B) occurs after preparation, as detailed onpage 250under "Completing Full Disk Encryption Deployment on a Client," which describes stages like policy application post-preparation.

Thus,Option Dis the most accurate and comprehensive answer based on the official documentation.

Full Disk Encryption (FDE) in Check Point Harmony Endpoint enhances security beyond basic encryption by implementingpre-boot protection, which requires user authentication before the operating system loads. This is detailed in theCP_R81.20_Harmony_Endpoint_Server_AdminGuide.pdfonpage 217, under "Check Point Full Disk Encryption":

"Combines Pre-boot protection, boot authentication, and strong encryption to make sure that only authorized users are given access to information stored on desktops and laptops."

This statement highlights that pre-boot protection is a distinct layer of security, ensuring that the system remains inaccessible until authentication is completed. Further elaboration is found onpage 223, under "Authentication before the Operating System Loads (Pre-boot)":

"Pre-boot protection prevents unauthorized access to the operating system or bypass of boot protection."

The pre-boot mechanism adds a critical layer by securing the system at the earliest stage of the boot process, distinguishing it from general encryption (which is a prerequisite but not the "additional layer" the question seeks). Thus,Option Bis the correct answer.

Option A ("By offering media encryption")is incorrect because media encryption is a feature of MEPP, not FDE (see page 280).

Option C ("By offering port protection")is also incorrect as port protection pertains to MEPP, not FDE (see page 280).

Option D ("By offering encryption")is too vague and does not specify the additional layer; encryption is inherent to FDE, but pre-boot protection is the added security mechanism.

In Check Point's Harmony Endpoint, the "heartbeat" refers to a periodic connection initiated by the endpoint client to the Endpoint Security Management Server. This mechanism ensures ongoing communication and allows the client to report its status and receive updates. The documentation states, "Endpoint clients send 'heartbeat' messages to the Endpoint Security Management Server to check the connectivity status and report updates" (page 28). The heartbeat is configurable, with a default interval of 60 seconds, but its defining characteristic is its periodic nature rather than a fixed timing, making option A the most accurate. Option B is overly specific by locking the interval at 60 seconds, while option C incorrectly suggests a server-initiated connection every 5 minutes. Option D is incorrect, as the heartbeat is not random but scheduled. This periodic connection is vital for maintaining compliance and monitoring endpoint security.

When deploying an Endpoint Policy Server, configuring the heartbeat interval is critical. The heartbeat interval defines how often the client must communicate with the server to verify policy status and updates. The amount of time allowed for the client to connect ensures consistent enforcement of policies.

Exact Extract from Official Document:

"The heartbeat interval and the time allowed for client connections are critical settings to configure when deploying an Endpoint Policy Server."

The Endpoint Client GUI in Check Point Harmony Endpoint provideseither automatic or manual promptingto protect removable storage media usage, depending on how the administrator configures the system. This functionality is part of the Media Encryption & Port Protection component, which allows flexible control over removable media such as USB drives. According to theCP_R81.20_Harmony_Endpoint_Server_AdminGuide.pdfonpage 282, under the section "Working with Actions in a Media Encryption & Port Protection Rule," the documentation states:

"You can configure rules to automatically encrypt media or prompt users to encrypt or access media in a protected manner."

This extract confirms that administrators can set policies to either automatically apply encryption (automatic prompting) or require user interaction (manual prompting) when removable media is detected. For example, an automatic rule might encrypt a USB drive without user intervention, while a manual rule might display a prompt in the Endpoint Client GUI asking the user to confirm encryption or access permissions. This dual capability makesOption B ("Either automatic or manual")the correct answer.

Option A ("Manual Only")is incorrect because the system supports automatic prompting, not just manual.

Option C ("Automatic Only")is incorrect because manual prompting is also an available option.

Option D ("Neither automatic nor manual")is false, as the documentation clearly describes both methods.

For the Endpoint Security Management Server to operate, theComplianceandNetwork Policy Managementblades must be enabled. This is indicated in theCP_R81.20_Harmony_Endpoint_Server_AdminGuide.pdfon page 23 under "Endpoint Security Architecture," where it describes the Management Server as hosting "Endpoint Security policy management and databases," which includes policy enforcement and compliance checking. Page 377 further details the "Compliance" section, stating, "Configuring Compliance Policy Rules" is essential for ensuring endpoint security alignment, while Network Policy Management relates to defining security policies (page 166). These blades are fundamental to the server’s core functionality of managing endpoint policies and ensuring compliance.

Option A ("all gateway-related blades") is incorrect, as gateway blades (e.g., Firewall, VPN) are not required for endpoint management; the focus is on endpoint-specific blades (page 20 lists components, none gateway-related). Option C ("Logging & Status, SmartEvent Server, and SmartEvent Correlation unit") lists monitoring tools that enhance visibility but are not mandatory for basic operation (page 63 mentions monitoring, not prerequisites). Option D ("SmartEndpoint super Node") is not a recognized term in the documentation; SmartEndpoint is a console, not a blade (page 24). Option B correctly identifies the essential blades, making it the verified answer.

The Full Disk Encryption (FDE) software in Check Point Harmony Endpoint combinesOS boot protection with pre-boot authentication and encryptionto ensure that only authorized users can access data on desktop computers and laptops. This is detailed in theCP_R81.20_Harmony_Endpoint_Server_AdminGuide.pdfonpage 217, under "Check Point Full Disk Encryption," where it states:

"Combines Pre-boot protection, boot authentication, and strong encryption to make sure that only authorized users are given access to information stored on desktops and laptops."

This extract highlights three key elements:

Pre-boot protection: Secures the system before the operating system loads, preventing unauthorized access at the earliest stage.

Boot authentication: Requires users to authenticate (e.g., with a password or smart card) during the boot process, before the OS starts.

Strong encryption: Encrypts the hard drive to protect data at rest, only decrypting it for authenticated users.

Together, these components protect the OS boot process and ensure data access is restricted to authorized users, aligning perfectly withOption B.

Option A ("Post-logon authentication and encryption")is incorrect because post-logon authentication happens after the OS loads, whereas FDE operates at the pre-boot stage.

Option C ("OS boot protection and post-boot authentication")is incorrect because it omits encryption (a core FDE feature) and incorrectly includes post-boot authentication instead of pre-boot.

Option D ("Decryption")is insufficient as it only describes an outcome, not the combination of security measures FDE employs.
