Discussion

Support for Server Message Block (SMB) file sharing is nonessential and must be disabled. The information system must be configured to provide only essential capabilities.

Check Content

Verify the macOS system is configured to disable Server Message Block sharing with the following command:

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

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

Fix Text

Configure the macOS system to disable Server Message Block sharing with the following command:

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

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