Protecting an Aruba Mobility Controller from unauthorized access involves several layers of security. One recommendation is to change the password recovery password, which is a special type of password used to recover access to the device in the event the admin password is lost. Changing this to something complex and unique adds an additional layer of security in the event the physical security of the device is compromised.

The recommended approach for preventing users in the 'user_group1' role from using gaming and peer-to-peer applications in an ArubaOS environment is to enable Deep Packet Inspection (DPI) and add application rules that specifically deny access to these types of applications for the role. DPI allows the network system to analyze the content of network traffic in real time and apply policies based on what it detects, including blocking specific applications like gaming and peer-to-peer sharing. This capability is essential for effectively managing application usage on the network and ensuring compliance with organizational policies. Application-specific rules provide precise control over the network traffic by identifying the application regardless of the network port used, making it a more effective method than blocking based on ports or IP addresses.

When an authentication attempt for a user's Windows domain computer is failing on a WPA3-Enterprise WLAN and the Mobility Controller is receiving Access-Rejects, one place to look for deeper insight is the RADIUS events within the CPPM Event Viewer. ClearPass Policy Manager (CPPM) logs all RADIUS authentication events, and the Event Viewer would show detailed information about why a particular authentication attempt was rejected. This could include reasons such as incorrect credentials, expired certificates, or policy mismatches. The CPPM Event Viewer is an essential troubleshooting tool within ClearPass to diagnose authentication issues, as indicated in the ClearPass Policy Manager documentation.

When responding to the detection of a Rogue AP, it's important to consider legal implications and to gather forensic evidence:

You should receive permission before containing an AP (Option C), as containing it could disrupt service and may have legal implications, especially if the AP is on a network that the organization does not own.

For forensic purposes, it is essential to document the event by copying out logs with relevant information, such as the time the AP was detected and the AP's MAC address (Option D). This information could be crucial if legal action is taken or if a detailed analysis of the security breach is required.

Automatically containing an AP without consideration for the context (Options A and E) can be problematic, as it might inadvertently interfere with neighboring networks and cause legal issues. Immediate containment without consideration of company policy (Option B) could also violate established incident response procedures.

WPA3-Enterprise enhances network security over WPA2-Enterprise through several improvements, one of which is the ability to operate in CNSA (Commercial National Security Algorithm) mode. This mode mandates the use of secure cryptographic algorithms during the 802.11 association process, ensuring that all communications are highly secure. The CNSA suite provides stronger encryption standards designed to protect sensitive government, military, and industrial communications. Unlike WPA2, WPA3's CNSA mode uses stronger cryptographic primitives, such as AES-256 in Galois/Counter Mode (GCM) for encryption and SHA-384 for hashing, which are not standard in WPA2-Enterprise.
