For WPA3-Enterprise with EAP-TLS, it's crucial that clients have a trusted certificate installed for the authentication process. EAP-TLS relies on a mutual exchange of certificates for authentication. Deploying client certificates signed by a CA that CPPM trusts ensures that the ClearPass Policy Manager can verify the authenticity of the client certificates during the TLS handshake process. Trust in the root CA is typically required for the server side of the authentication process, not the client side, which is covered by the client’s own certificate.

Without the integration of Aruba ClearPass or other advanced network access control solutions, ArubaOS devices (controllers and Instant APs) are able to use DHCP fingerprinting to assign roles to clients. This method allows the devices to identify the type of client devices connecting to the network based on the DHCP requests they send. While this is a more basic form of endpoint classification compared to the capabilities provided by ClearPass, it still enables some level of access control based on device type. This functionality and its limitations are described in Aruba's product documentation for ArubaOS devices, highlighting the benefits of integrating a full-featured solution like ClearPass for more granular and powerful endpoint classification capabilities.

In the context of the ArubaOS Security Dashboard, if the goal is to find company clients that have connected to devices potentially operated by hackers, you would look for a client that is classified as 'Interfering' (indicating a security threat) while being connected to an 'AP Classification: Rogue'. A rogue AP is one that is not under the control of network administrators and is considered malicious or a security threat. Therefore, the client fitting this description is:

• MAC address: d8:50:e6:f3:70:ab; Client Classification: Interfering; AP Classification: Rogue

Given the error message from the ClearPass Policy Manager (CPPM) Event Viewer, indicating a RADIUS authentication attempt from an unknown Network Access Device (NAD), you should check that the IP address the Mobility Controller (MC) is using to communicate with CPPM matches the IP address defined for the MC in the CPPM's device inventory. If there is a mismatch in IP addresses, CPPM will not recognize the MC as a known device and will not process the authentication request, leading to the error observed.References:
