Fix Recommendation

Update the EDSP.

Monitor the software files (e.g., *.exe, *.bat, *.com, *.cmd, and *.dll) on Exchange servers for unauthorized changes against a baseline on a weekly basis.

Note: This can be done with the use of various monitoring tools.

Check Contents

Review the Email Domain Security Plan (EDSP).

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 software files are not monitored for unauthorized changes, this is a finding.

Note: A properly configured HBSS Policy Auditor File Integrity Monitor (FIM) module will meet the requirement for file integrity checking. The Asset module within HBSS does not meet this requirement.
