Cisco ASA Audit Event: 305011

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.

305011: Built TCP, UDP, or ICMP translation

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-6-305011: Built {dynamic|static} {TCP|UDP|ICMP} translation from interface_name: real_address / real_port [(idfw_user)] to interface_name: mapped_address / mapped_port.

Event 305011 is generated when a TCP, UDP, or ICMP address translation slot is created. The slot would translate the source address from the local side to the global side. In reverse, the slot would also translate the destination address from the global side to the local side.
