What is a use case for the HPE Aruba Networking ClearPass OnGuard dissolvable agent?

  1. Continuously monitoring Windows domain clients for compliance
  2. Implementing a one-time compliance scan
  3. Auto-remediating posture issues on clients
  4. Periodically scanning Linux clients for security issues

Answer(s): B

Explanation:

The use case for the HPE Aruba Networking ClearPass OnGuard dissolvable agent is implementing a one-time compliance scan. The dissolvable agent is designed to perform a compliance check without requiring a permanent installation on the client device. This is ideal for environments where a quick, temporary assessment of the device's security posture is needed without the overhead of a persistent agent.

1. Dissolvable Agent: The dissolvable agent is downloaded and executed on the client device for a single session, performing the necessary compliance checks before being removed automatically.

2. One-time Compliance Scan: This method is particularly useful for guest or unmanaged devices where a temporary compliance scan is sufficient to ensure security standards are met.
3. Minimal Impact: Since the agent does not persist on the client device, it minimizes the impact on the user's system and does not require ongoing maintenance or updates.


Reference:

ClearPass OnGuard documentation details the capabilities and use cases for the dissolvable agent, emphasizing its role in one-time compliance assessments.



Which use case is fulfilled by applying a time range to a firewall rule on an AOS device?

  1. Enforcing the rule only during the specified time range
  2. Tuning the session timeout for sessions established with this rule
  3. Locking clients that violate the rule for the specified time range
  4. Setting the time range over which hit counts for the rule are aggregated

Answer(s): A

Explanation:

Applying a time range to a firewall rule on an AOS device fulfills the use case of enforcing the rule only during the specified time range. This allows administrators to control when specific firewall rules are active, which can be useful for implementing policies that only need to be in effect during certain hours, such as blocking or allowing access to specific resources outside of business hours.

1. Time-Based Enforcement: The firewall rule will be active only during the specified time range, ensuring that the rule's policies are enforced only when needed.
2. Use Case: This feature is useful for scenarios like limiting access to certain applications or websites during working hours, or enabling enhanced security measures during off-hours.
3. Flexibility: Provides flexibility in security policy management by allowing dynamic adjustment of rules based on time schedules.


Reference:

Aruba's AOS device documentation and firewall rule configuration guides detail how to apply time ranges to firewall rules for time-based policy enforcement.



A company wants HPE Aruba Networking ClearPass Policy Manager (CPPM) to respond to Syslog messages from its Palo Alto Next Generation Firewall (NGFW) by quarantining clients involved in security incidents.

Which step must you complete to enable CPPM to process the Syslogs properly?

  1. Configure the Palo Alto as a context server on CPPM.
  2. Install a Palo Alto Extension through ClearPass Guest.
  3. Enable Insight and ingress event processing on the CPPM server.
  4. Configure CPPM to trust the root CA certificate for the NGFW.

Answer(s): A

Explanation:

To enable HPE Aruba Networking ClearPass Policy Manager (CPPM) to process Syslog messages from a Palo Alto Next Generation Firewall (NGFW) and quarantine clients involved in security incidents, you need to configure the Palo Alto as a context server on CPPM. This setup allows CPPM to receive and understand the context of the Syslog messages sent by the Palo Alto NGFW, enabling it to take appropriate actions such as quarantining clients.

1. Context Server Configuration: Configuring the Palo Alto NGFW as a context server in CPPM ensures that CPPM can process and respond to Syslog messages effectively.
2. Security Incident Response: By understanding the context of the Syslog messages, CPPM can automatically trigger actions like client quarantine based on security incidents detected by the NGFW.
3. Integration: This integration enhances the overall security posture by enabling coordinated responses between the firewall and CPPM.


Reference:

ClearPass integration guides and context server configuration documentation provide detailed steps on setting up and utilizing context servers for security incident management.



A company is implementing a client-to-site VPN based on tunnel-mode IPsec.

Which devices are responsible for the IPsec encapsulation?

  1. Gateways at the remote clients' locations and devices accessed by the clients at the main site
  2. The remote clients and devices accessed by the clients at the main site
  3. The remote clients and a gateway at the main site
  4. Gateways at the remote clients' locations and a gateway at the main site

Answer(s): C

Explanation:

In a client-to-site VPN based on tunnel-mode IPsec, the remote clients and a gateway at the main site are responsible for the IPsec encapsulation. The remote clients initiate the VPN connection and encapsulate their traffic in IPsec, which is then decapsulated by the gateway at the main site.

1. IPsec Encapsulation: The remote clients encapsulate their traffic using IPsec protocols before sending it over the internet to the main site.
2. Gateway Role: The gateway at the main site receives the encapsulated traffic, decapsulates it, and forwards it to the internal network. Similarly, traffic from the main site to the remote clients is encapsulated by the gateway and decapsulated by the clients.
3. Security: This setup ensures that data is securely transmitted between the remote clients and the main site, protecting it from eavesdropping and tampering.


Reference:

Aruba and general IPsec VPN configuration guides provide detailed information on setting up client-to-site VPNs, highlighting the roles of remote clients and gateways in IPsec encapsulation.
