Vulnerability discussion

An Emergency Administrator Account must be created. Interview the SA to determine if an emergency administrator account exists and is stored with its password in a secure location. This emergency account should have a UID less than "500", and be hidden from view.

Check content

To check to see if UIDs below "500" are hidden, run the following command: sudo defaults read /Library/Preferences/com.apple.loginwindow Hide500Users If the result is not "1", this is a finding.

Fix text

To hide user accounts below "500", run the following command: sudo defaults write /Library/Preferences/com.apple.loginwindow Hide500Users -bool YES

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.
