The network device must log all interface access control lists (ACL) deny statements.
Interface ACL deny statements are not logged.
Auditing and logging are key components of any security architecture. It is essential for security personnel to know what is being done, attempted to be done, and by whom in order to compile an accurate risk assessment. Auditing the actions on network devices provides a means to recreate an attack, or identify a configuration mistake on the device.
Configure interface ACLs to log all deny statements.
Review the network device interface ACLs to verify all deny statements are logged. If deny statements are not logged, this is a finding.
