Cisco ASA Audit Event: 313005

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.

313005: No matching connection for ICMP error message

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-4-313005: No matching connection for ICMP error message:icmp_msg_info on interface_name interface. Original IP payload: embedded_frame_info icmp_msg_info = icmp src src_interface_name: src_address [([idfw_user | FQDN_string], sg_info)] dst dest_interface_name :dest_address [([idfw_user | FQDN_string ],sg_info)] (type icmp_type, code icmp_code) embedded_frame_info = prot src source_address /source_port [([idfw_user | FQDN_string ], sg_info)] dst dest_address/dest_port [(idfw_user |FQDN_string ), sg_info].

Event 313005 is generated when ICMP error packets are dropped by the ASA because the ICMP error messages are not related to any session already established in the ASA.

How could you resolve this situation?

If the cause is an attack, the host can be denied by using ACLs
