QUESTION: 21

Admins have recently turned on Wireless IDS/IPS infrastructure detection at the high level on HPE Aruba Networking APs.
When you check WIDS events, you see several RTS rate and CTS rate anomalies, which were triggered by neighboring APs.

What can you interpret from this event?

These neighboring APs are likely to be wireless clients that are inappropriately bridging their wired and wireless NICs; you should track down and remove them.
These neighboring APs might be hackers trying to launch a DoS, but are more likely operating normally; you should start by tuning the event thresholds.
These neighboring APs are actually rogue APs, and you should enable wireless tarpit containment on them.
These neighboring APs are actually rogue APs, and you should enable wireless de-authentication containment on them.

Answer(s): B

Explanation:

When Wireless IDS/IPS infrastructure detection reports RTS (Request to Send) and CTS (Clear to Send) rate anomalies triggered by neighboring APs, it is often an indication of unusual, but not necessarily malicious, behavior. These anomalies can be caused by neighboring APs operating normally but under specific conditions that trigger the alerts. Before assuming a security threat, it is recommended to tune the event thresholds to better match the environment and reduce false positives. This approach helps to distinguish between normal operations and potential DoS attacks.

Aruba's Wireless IDS/IPS configuration guides provide information on interpreting events,

adjusting thresholds, and distinguishing between legitimate and malicious activities in a wireless network environment.

QUESTION: 22

HPE Aruba Networking Central displays an alert about an Infrastructure Attack that was detected. You go to the Security > RAPIDS events and see that the attack was "Detect adhoc using Valid SSID."

What is one possible next step?

Use HPE Aruba Networking Central floorplans or the detecting AP identities to locate the general area for the threat.
Look for the IP address associated with the offender and then check for that IP address among HPE Aruba Networking Central clients.
Make sure that you have tuned the threshold for that check, as false positives are common for it.
Make sure that clients have updated drivers, as faulty drivers are a common explanation for this attack type.

Answer(s): A

Explanation:

When HPE Aruba Networking Central detects an Infrastructure Attack, such as "Detect adhoc using Valid SSID," the next step is to locate the general area of the threat. You can use HPE Aruba Networking Central floorplans or the identities of the detecting APs to pinpoint the approximate location of the adhoc network. This allows you to physically investigate and address the source of the threat, ensuring that unauthorized or rogue networks are quickly identified and mitigated.

Reference:

Aruba Central documentation and RAPIDS events management guides offer strategies for locating and responding to detected security threats, emphasizing the use of network tools and floorplans to effectively address potential vulnerabilities.

QUESTION: 23

A company has a variety of HPE Aruba Networking solutions, including an HPE Aruba Networking infrastructure and HPE Aruba Networking ClearPass Policy Manager (CPPM). The company passes traffic from the corporate LAN destined to the data center through a third-party SRX firewall. The company would like to further protect itself from internal threats.

What is one solution that you can recommend?

Have the third-party firewall send Syslogs to CPPM, which can work with network devices to lock internal attackers out of the network.
Use tunnel mode SSIDs and user-based tunneling (UBT) on AOS-CX switches to pass all internal traffic directly through the third-party firewall.
Add ClearPass Device Insight (CPDI) to the solution; integrate it with the third-party firewall to develop more complete device profiles.
Configure CPPM to poll the third-party firewall for a broad array of information about internal clients, such as profile and posture.

Answer(s): A

Explanation:

To further protect the company from internal threats, you can recommend having the third-party SRX firewall send Syslogs to HPE Aruba Networking ClearPass Policy Manager (CPPM). ClearPass can analyze these logs to detect potential security incidents and coordinate with network devices to respond to threats. By integrating Syslog data from the firewall, CPPM can identify malicious activities and take actions such as locking internal attackers out of the network or triggering specific security policies. This approach enhances the company's internal threat detection and response capabilities.

Reference:

Aruba's ClearPass documentation on integrating with third-party security solutions and utilizing Syslog data for enhanced network security provides detailed guidance on setting up and using these features.

QUESTION: 24

A company wants to apply a standard configuration to all AOS-CX switch ports and have the ports dynamically adjust their configuration based on the identity of the user or device that connects. They want to centralize configuration of the identity-based settings as much as possible.

What should you recommend?

Having HPE Aruba Networking ClearPass Policy Manager (CPPM) send standard RADIUS AVPs to customize port settings
Having switches pull port configurations dynamically from HPE Aruba Networking Activate
Having switches download user-roles from HPE Aruba Networking gateways
Having switches download user-roles from HPE Aruba Networking ClearPass Policy Manager (CPPM)

Answer(s): D

Explanation:

For a company that wants to apply a standard configuration to all AOS-CX switch ports and dynamically adjust their configuration based on the identity of the user or device that connects, the best approach is to have the switches download user-roles from HPE Aruba Networking ClearPass Policy Manager (CPPM). This method centralizes the configuration of identity-based settings in CPPM, allowing it to dynamically assign roles and policies to switch ports based on authentication and authorization results. This ensures consistent and secure network access control tailored to each user or device.

Reference:

Aruba ClearPass and AOS-CX documentation provide comprehensive details on configuring user-roles, dynamic port configuration, and integrating ClearPass for centralized identity- based network management.
