Vulnerability discussion

Depending on the information sharing circumstance, the sharing partner may be defined at the individual, group, or organization level and information may be defined by specific content, type, or security categorization.The operating system must restrict data in some manner (e.g., privileged medical, contract-sensitive, proprietary, personally identifiable information, special access programs/compartments) and must provide the capability to automatically enable authorized users to make information sharing decisions based upon access authorizations.NFS should be disabled.

Check content

To check if NFS is disabled, run the following command: sudo /usr/libexec/PlistBuddy -c "print com.apple.lockd:Disabled" /var/db/launchd.db/com.apple.launchd/overrides.plist If the returned value isn't "true" or doesn't exist, this is a finding.

Fix text

To disable file sharing, run the following command: sudo defaults write /private/var/db/launchd.db/com.apple.launchd/overrides.plist "com.apple.lockd" -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.
