Summary

Periodic security audits must be a part of any proper security plan. The audit must include the following steps, at a minimum:

Check for appropriate security policies.
Check to see that all systems have updated patches for the operating system and applications. Also check to see whether a patch management plan is in place and documented.
Check physical security.
Probe the system using port scanners and other software to detect and correct any flaws.
Document the specific steps taken in the security audit, any flaws found, and any corrective actions that were taken or are recommended.
