Determine whether the system is monitored for unauthorized changes to system files (e.g., *.exe, *.bat, *.com, *.cmd, and *.dll) against a baseline on a weekly basis.

A properly configured and approved DoD ESS solution that supports a File Integrity Monitor (FIM) module will meet the requirement for file integrity checking.
