Cisco ASA Audit Event: 109017

109017: User exceeded authentication proxy connection limit

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-4-109017: User at IP_address exceeded auth proxy connection limit (max)

Event 109017 is generated when a user exceeds the user authentication proxy limit and opens too many connections to the proxy. The IP address of the user is specified in the message.

How could you resolve this situation?

You can increase the proxy limit by entering the 'proxy_limit' command or ask the user to close unused connections. If this event occurs repeatedly, it may indicate a possible DoS attack.
