Cisco ASA Audit Event: 313005

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
