Discussion

Support for both Screen Sharing and Apple Remote Desktop is nonessential and must be disabled. The information system must be configured to provide only essential capabilities. Disabling Screen Sharing and Apple Remote Desktop helps prevent unauthorized connection of devices, transfer of information, and tunneling.

Check Content

Verify the macOS system is configured to disable Screen Sharing and Apple Remote Desktop with the following command:

/bin/launchctl print-disabled system | /usr/bin/grep -c '"com.apple.screensharing" => disabled'

If the result is not "1", this is a finding.

Fix Text

Configure the macOS system to disable Screen Sharing and Apple Remote Desktop with the following command:

/bin/launchctl disable system/com.apple.screensharing

The system may need to be restarted for the update to take effect.

NOTE: This will apply to the whole system.
