Remove or disable any services that are not required.

Check Contents

Review the Email Domain Security Plan (EDSP).

Note: Required services will vary between organizations and will vary depending on the role of the individual system. Organizations will develop their own list of services, which will be documented and justified with the ISSO. The site’s list will be provided for any security review. Services that are common to multiple systems can be addressed in one document. Exceptions for individual systems should be identified separately by system.

Open a Windows PowerShell and enter the following command:

Get-Service | Where-Object {$_.status -eq 'running'}

The command returns a list of installed services and the status of that service.

If the site has not documented the services required for its system(s), this is a finding.

If any undocumented or unnecessary services are running, this is a finding.
