Information

The macOS system must disable Server Message Block (SMB) sharing.

GROUP ID: V-277085
RULE ID: SV-277085r1148707

Support for SMB file sharing is nonessential and must be disabled.

The information system must be configured to provide only essential capabilities. Enabling any service increases the attack surface for an intruder. By disabling unnecessary services, the attack surface is minimized.

Solution

Configure the macOS system to disable SMB sharing with the following command:

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

The system may need a restart for the update to take effect.
