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. |

Update the EDSP to specify that the organization monitors system files on servers for unauthorized changes against a baseline on a weekly basis or verify that this information is documented by the organization. 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. |
