Title

Disable Server Message Block Sharing

Control

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

Discussion

Support for Server Message Block (SMB) file sharing is non-essential and _MUST_ be disabled.

The information system _MUST_ be configured to provide only essential capabilities.

Fix

[source,bash]
----
/bin/launchctl disable system/com.apple.smbd

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