A company is implementing HPE Aruba Networking Wireless IDS/IPS (WIDS/WIPS) on its AOS-10 APs, which are managed in HPE Aruba Networking Central.

What is one requirement for enabling detection of rogue APs?

  1. Each VLAN in the network assigned on at least one AP's or AM's port
  2. A Foundation with Security license for each of the APs
  3. One AM deployed for every one AP deployed
  4. A manual radio profile that enables non-regulatory channels

Answer(s): B

Explanation:

To enable the detection of rogue APs with HPE Aruba Networking Wireless IDS/IPS (WIDS/WIPS) on AOS-10 APs managed in HPE Aruba Networking Central, each AP must have a Foundation with Security license. This license enables advanced security features, including rogue AP detection, which is crucial for maintaining a secure wireless environment and protecting against unauthorized access points.


Reference:

Aruba's licensing documentation and WIDS/WIPS setup guides specify the need for appropriate licenses to activate security features such as rogue AP detection.



A company uses HPE Aruba Networking ClearPass Device Insight (CPDI) (the standalone application option). In the details for a generic device cluster, you see a recommendation for "Windows 8/10" with 70% accuracy.

What does this mean?

  1. CPDI has detected that these devices match about 70% of the system rule for defining "Windows 8/10" devices.
  2. CPDI has matched these devices against several, conflicting system rules. 70% of those rules are for "Windows 8/10" devices.
  3. CPDI has grouped this cluster with similar classified devices. 70% of those classified devices are "Windows 8/10."
  4. CPDI has used MAC OUI to group these devices together. The average device's MAC address matches 70% of the "Windows 8/10" OUI.

Answer(s): A

Explanation:

When HPE Aruba Networking ClearPass Device Insight (CPDI) shows a recommendation for "Windows 8/10" with 70% accuracy for a generic device cluster, it means that CPDI has detected that these devices match about 70% of the system rule criteria for defining "Windows 8/10" devices. This percentage indicates the confidence level based on the observed characteristics and behavior of the devices, helping administrators understand the likelihood that these devices are indeed running Windows 8 or 10.


Reference:

ClearPass Device Insight documentation provides details on how device classification and accuracy percentages are determined, explaining the matching process against system rules.



Refer to the Exhibit.



All of the switches in the exhibit are AOS-CX switches.

What is the preferred configuration on Switch-2 for preventing rogue OSPF routers in this network?

  1. Disable OSPF entirely on VLANs 10-19.
  2. Configure OSPF authentication on VLANs 10-19 in password mode.
  3. Configure OSPF authentication on Lag 1 in MD5 mode.
  4. Configure passive-interface as the OSPF default and disable OSPF passive on Lag 1.

Answer(s): C

Explanation:

To prevent rogue OSPF routers in the network shown in the exhibit, the preferred configuration on Switch-2 is to configure OSPF authentication on Lag 1 in MD5 mode. This setup enhances security by ensuring that only routers with the correct MD5 authentication credentials can participate in the OSPF routing process. This method protects the OSPF sessions against unauthorized devices that might attempt to introduce rogue routing information into the network.

1. OSPF Authentication: Implementing MD5 authentication on Lag 1 ensures that OSPF updates are secured with a cryptographic hash. This prevents unauthorized OSPF routers from establishing peering sessions and injecting potentially malicious routing information.
2. Secure Communication: MD5 authentication provides a higher level of security compared to simple password authentication, as it uses a more robust hashing algorithm.
3. Applicability: Lag 1 is the primary link between Switch-1 and Switch-2, and securing this link helps protect the integrity of the OSPF routing domain.


Reference:

Aruba's AOS-CX switch documentation and OSPF configuration guides detail how to set up MD5 authentication for OSPF to enhance network security against rogue devices.



A company has HPE Aruba Networking gateways that implement gateway IDS/IPS. Admins sometimes check the Security Dashboard, but they want a faster way to discover if a gateway starts detecting threats in traffic.

What should they do?

  1. Use Syslog to integrate the gateways with HPE Aruba Networking ClearPass Policy Manager (CPPM) event processing.
  2. Integrate HPE Aruba Networking ClearPass Device Insight (CPDI) with Central and schedule hourly reports.
  3. Set up email notifications using HPE Aruba Networking Central's global alert settings.
  4. Set up Webhooks that are attached to the HPE Aruba Networking Central Threat Dashboard.

Answer(s): C

Explanation:

For a faster way to discover if a gateway starts detecting threats in traffic, admins should set up email notifications using HPE Aruba Networking Central's global alert settings. This setup ensures that the security team is promptly informed via email whenever the IDS/IPS on the gateways detects any threats, allowing for immediate investigation and response.

1. Email Notifications: By configuring email notifications, admins can receive real-time alerts directly to their inbox, reducing the time to discover and react to security incidents.
2. Global Alert Settings: HPE Aruba Networking Central's global alert settings allow for customization of alerts based on specific security events and thresholds, providing flexibility in monitoring and response.
3. Proactive Monitoring: This proactive approach ensures that the security team is always aware of potential threats without the need to constantly check the Security Dashboard manually.


Reference:

Aruba Central documentation on setting up alerts and notifications provides detailed steps on configuring email notifications for various security events.
