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 information system but does not log out because of the temporary nature of the absence. Rather than relying on the user to lock their operating system session manually prior to leaving the workstation, operating systems must be able to identify when a user's session has idled, and take action to initiate the session lock. The session lock is implemented at the point where session activity can be determined and/or controlled.

Check Content

Verify the operating system initiates a session lock a for graphical user interfaces when the screensaver is activated. 

Note: If the system does not have GNOME installed, this requirement is Not Applicable.

If GNOME is installed, check to see a session lock occurs when the screensaver is activated with the following command:

     # grep -i lock-delay /etc/dconf/db/local.d/*
     lock-delay=uint32 5

If the "lock-delay" setting is missing, or is not set to "5" or less, this is a finding.
