Vulnerability 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

The NFS stat daemon must be disabled. To check if the NFS stat daemon is disabled, run the following command: sudo /usr/libexec/PlistBuddy -c 'print com.apple.statd.notify:Disabled' /var/db/launchd.db/com.apple.launchd/overrides.plist If the returned value isn't 'true', this is a finding.

Fix text

To disable the NFS stat daemon, run the following command: sudo defaults write /private/var/db/launchd.db/com.apple.launchd/overrides.plist 'com.apple.statd.notify' -dict Disabled -bool true

Pro Tips

Lavender hyperlinks in small type off to the right (of CSS class id, if you view the page source) point to globally unique URIs for each document and item. Copy the link location and paste anywhere you need to talk unambiguously about these things.

You can obtain data about documents and items in other formats. Simply provide an HTTP header Accept: text/turtle or Accept: application/rdf+xml.
