Cisco ASA Audit Event: 113020

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.

113020: Clock skew with server more than 300 seconds

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-3-113020: Kerberos error: Clock skew with server ip_address greater than 300 seconds.


Event 113020 is generated when authentication for an IPsec or WebVPN user through a Kerberos server fails because the clocks on the ASA and the server are more than five minutes (300 seconds) apart. When this occurs, attempts to get connected are rejected. The Kerberos server's IP address is specified in the message. 

How could you resolve this situation?

Synchronize the clocks on the ASA and the Kerberos server.
