Assessment Title

Rule Text

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

Description

Discussion Text

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.

Assessment Procedure

Check Text

Verify the macOS system is configured to disable NFS service with the following commands:

isDisabled=$(/sbin/nfsd status | /usr/bin/awk '/nfsd service/ {print $NF}')    
  if [[ "$isDisabled" == "disabled" ]] && [[ -z $(/usr/bin/pgrep nfsd) ]]; then
    echo "pass"
  else
    echo "fail"
  fi

If the result is not "pass", this is a finding.

Implementation Procedure

Fix Text

Configure the macOS system to disable NFS service with the following commands:

/bin/launchctl disable system/com.apple.nfsd
/bin/rm -rf /etc/exports

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