Title
The NFS lock daemon must be disabled unless required. (Cat II impact)
Discussion
If the system does not require access to NFS (Network File System) file shares or is not acting as an NFS server, then 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.
Check Content
If the NFS lock daemon is required, this is not applicable. To check if the NFS lock daemon is disabled, use the following command: sudo launchctl print-disabled system | grep com.apple.lockd If the results do not show the following: "com.apple.lockd" => true this is a finding.
Fix Text
To disable the 'NFS lock' daemon, run the following command: sudo launchctl disable system/com.apple.lockd The system may need to be restarted for the update to take effect.
