APPL-11-002001 - The macOS system must be configured to disable SMB File Sharing unless it is required.

Information

File Sharing is usually non-essential and must be disabled if not required. Enabling any service increases the attack surface for an intruder. By disabling unnecessary services, the attack surface is minimized.

Solution

To disable the SMB File Sharing service, run the following command:

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

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