Cisco ASA Audit Event: 214001

214001: Terminating manager session

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-2-214001:Terminating manager session from IP_addresson interface interface_name.Reason: incoming encrypted data (number bytes) longer than number bytes.

Event 214001 is generated when an incoming encrypted data packet destined for the ASA management port indicates a packet length exceeding the specified upper limit. As this might be a hostile event, the ASA immediately terminates the management connection.

How could you resolve this situation?

Ensure that the management connection was initiated by Cisco Secure Policy Manager.
