Discussion

A session 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 want to log out because of the temporary nature of the absence. The session lock is implemented at the point where session activity can be determined. The ability to enable/disable a session lock is given to the user by default. Disabling the user's ability to disengage the graphical user interface session lock provides the assurance that all sessions will lock after the specified period of time.

Verify the operating system prevents a user from overriding the screensaver idle-activation-enabled setting for the graphical user interface. 

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

Determine which profile the system database is using with the following command:
     # grep system-db /etc/dconf/profile/user
     system-db:local

Check for the idle-activation-enabled setting with the following command:

Note: The example below is using the database "local" for the system, so the path is "/etc/dconf/db/local.d". This path must be modified if a database other than "local" is being used.

     # grep -i idle-activation-enabled /etc/dconf/db/local.d/locks/*
     /org/gnome/desktop/screensaver/idle-activation-enabled

If the command does not return a result, this is a finding.
