Vulnerability discussion

A session time-out lock is a temporary action taken when a user stops work and moves away from the immediate physical vicinity of the system but does not log out because of the temporary nature of the absence. The organization defines the period of inactivity to pass before a session lock is initiated, so this must be configurable.

Check content

To check if the system has a configuration profile configured to enable the screen saver after a time-out period, run the following command: system_profiler SPConfigurationProfileDataType | grep idleTime | awk '{ print $3 }' | sed 's/;//' The check should return a value of "900" or less, if not, this is a finding.

Fix text

This setting is enforced using a 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.
