Cisco ASA Audit Event: 320001

Cisco ASA Events

The logs of network perimeter devices such as firewalls, antivirus applications and intrusion prevention systems contain crucial information that helps to pre-emptively block security attacks and breaches. Hence, it's mandatory for you to monitor and audit these logs. Because Cisco ASA provides the combined functionality of all the three, it becomes all the more important to monitor its logs. 

ManageEngine's EventLog Analyzer, a comprehensive log management solution, collects and analyzes the log data from Cisco ASA devices, triggers alerts and generate reports on detected security incidents thus helping you to take suitable measures against security threats, if any.

320001: Subject name of the peer cert not allowed for connection

Cisco ASA is a security device that provides the combined capabilities of a firewall, an antivirus, and an intrusion prevention system. It also facilitates virtual private network (VPN) connections. It helps to detect threats and stop attacks before they spread through the network.

Message: %ASA-3-320001: The subject name of the peer cert is not allowed for connection.

Event 320001 is generated when the peer certificate includes a subject name that does not match the output of the 'ca verifycertdn' command. This might denote a man-in-the-middle attack where a device spoofs the peer IP address and tries to intercept a VPN connection from the ASA.
