Vulnerability discussion

Users must be prompted to enter their passwords when unlocking the screen saver. The screen saver acts as a session lock and prevents unauthorized users from accessing the current user's account.

Check content

To check if the system will prompt users to enter their passwords to unlock the screen saver, run the following command: /usr/sbin/system_profiler SPConfigurationProfileDataType | /usr/bin/grep askForPassword If there is no result, or if "askForPassword" is not set to "1", this is a finding.

Fix text

This setting is enforced using the "Login Window Policy" configuration profile.

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.
