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 manually lock their operating system session prior to vacating the vicinity, 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 after a 15-minute period of inactivity for graphical user interfaces.

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

Check for the session lock settings with the following commands:

     # grep -i idle-activation-enabled /etc/dconf/db/local.d/*
     idle-activation-enabled=true

If "idle-activation-enabled" is not set to "true", this is a finding.
