Cisco ASA Audit Event: 322001

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.

322001: Deny MAC address

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-3-322001: Deny MAC address MAC_address, possible spoof attempt on interface interface.

Event 322001 is generated when the ASA receives a packet from an offending MAC address on a specified interface, but the source MAC address in the packet is statically bound to another interface in the configuration. This could possibly be caused by a MAC spoofing attack or a misconfiguration.

How could you resolve this situation?

Check the configuration and take appropriate action by either finding the offending host or correcting the configuration.

We can help you simplify log management and improve your organization's security with EventLog Analyzer.
