The exhibit shows a screenshot of a Malwarebytes alert that indicates that a website was blocked due to compromise. The alert contains the following information:

• The type of protection: Web Protection
• The website that was blocked: 10.254.1.21
• The port that was used: 80
• The process that initiated the connection: C:\Program Files (x86)\Google\Chrome\Application\chrome.exe
• The IP address of the device that initiated the connection: 10.1.26.151

The IP address of the device that initiated the connection is the one that should be recorded as a possibly compromised client, as it indicates that the device tried to access a malicious website that could infect it with malware or steal its data. In this case, the IP address of the possibly compromised client is 10.1.26.151.

According to the AOS-CX User Guide, one way to configure the VLAN setting for the reception role is to assign a consistent name to VLAN 14, 24, or 34 on each access layer switch and reference that name in the enforcement profile VLAN settings. This way, the switches can download the role settings from CPPM and apply the correct VLAN based on the name, rather than the ID. For example, the enforcement profile VLAN settings could be:

And the VLAN configuration on each switch could be:

A DNS SAN (Subject Alternative Name) is an extension of the X.509 certificate standard that allows specifying additional hostnames or IP addresses that the certificate can be used for. A DNS SAN is useful for validating the identity of the server or client that presents the certificate, especially when the common name (CN) field does not match the hostname or IP address of the server or client.

In this case, the certificate has a CN of mc41.site94.example.com, which is the fully qualified domain name (FQDN) of the standalone Aruba Mobility Controller (MC). However, this CN may not match the hostname or IP address that the MC uses for the Web UI or for implementing RadSec with Aruba ClearPass Policy Manager. For example, if the MC uses a different FQDN, such as mc41.example.com, or an IP address, such as 192.168.1.41, for these purposes, then the certificate would not be valid for them. Therefore, the certificate should have a DNS SAN that includes all the possible hostnames or IP addresses that the MC may use for the Web UI and RadSec.
