Description
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 Text ( C-53813r1_chk )
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.
