Cisco ASA Audit Event: 201012

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.
