Cisco ASA Audit Event: 109017

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.

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.

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