Title

The Microsoft FTP service must not be installed unless required. (Cat II impact)

Discussion

Unnecessary services increase the attack surface of a system. Some of these services may not support required levels of authentication or encryption.

Check Content

If the server has the role of an FTP server, this is NA. Open "PowerShell". Enter "Get-WindowsFeature | Where Name -eq Web-Ftp-Service". If "Installed State" is "Installed", this is a finding. An Installed State of "Available" or "Removed" is not a finding. If the system has the role of an FTP server, this must be documented with the ISSO.

Fix Text

Uninstall the "FTP Server" role. Start "Server Manager". Select the server with the role. Scroll down to "ROLES AND FEATURES" in the right pane. Select "Remove Roles and Features" from the drop-down "TASKS" list. Select the appropriate server on the "Server Selection" page and click "Next". Deselect "FTP Server" under "Web Server (IIS)" on the "Roles" page. Click "Next" and "Remove" as prompted.
