Monitoring system files for changes against a baseline on a regular basis may help detect the possible introduction of malicious code on a system.

Check Content

Determine whether the site monitors system files (e.g., *.exe, *.bat, *.com, *.cmd, and *.dll) on servers for unauthorized changes against a baseline on a weekly basis. If system files are not monitored for unauthorized changes, this is a finding. A properly configured McAfee Application Control and Change Control (MACC) module will meet the requirement for file integrity checking.

Fix Text

Monitor system files (e.g., *.exe, *.bat, *.com, *.cmd, and *.dll) on servers for unauthorized changes against a baseline on a weekly basis. This can be done with the use of various monitoring tools.
