Description
If the system does not require access to NFS file shares or is not acting as an NFS server, support for NFS is non-essential and NFS services must be disabled. NFS is a network file system protocol supported by UNIX-like operating systems. Enabling any service increases the attack surface for an intruder. By disabling unnecessary services, the attack surface is minimized.

Fix Text (F-16024r397051_fix)
To disable the NFS lock daemon, run the following command: /usr/bin/sudo /bin/launchctl disable system/com.apple.lockd The system may need to be restarted for the update to take effect.
