Vulnerability discussion

File Sharing is non-essential and must be disabled. Enabling any service increases the attack surface for an intruder. By disabling unnecessary services, the attack surface is minimized.

Check content

SMB File Sharing must be disabled. To check if SMB File Sharing is disabled, run the following command: sudo /usr/libexec/PlistBuddy -c 'print com.apple.smbd: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 SMB File Sharing, run the following command: sudo defaults write /private/var/db/launchd.db/com.apple.launchd/overrides.plist 'com.apple.smbd' -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.
