Title

Disable Network File System Service

Control

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

Discussion

Support for Network File Systems (NFS) services is non-essential and, therefore, _MUST_ be disabled.
