Description
Auditing and logging are key components of any security architecture. It is essential for security personnel to know what is being done or attempted to be done, and by whom, 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.
ℹ️ Check
Review the router interface access control lists (ACLs) to verify all deny statements are logged. If packets being dropped are not logged, this is a finding.
✔️ Fix
Configure interface ACLs to log all deny statements.
