Title

The macOS system must disable Network File System (NFS) service.

Control

Verify the macOS system is configured to disable NFS service with the following command: /bin/launchctl print-disabled system | /usr/bin/grep -c '"com.apple.nfsd" => disabled' If the result is not "1", this is a finding.

Discussion

Support for NFS services is nonessential and, therefore, must be disabled. Enabling any service increases the attack surface for an intruder. By disabling unnecessary services, the attack surface is minimized.
