Cisco ASA Audit Event: 214001

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.

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.
