Information

OL 9 must automatically lock graphical user sessions after 15 minutes of inactivity.

GROUP ID: V-271674
RULE ID: SV-271674r1155332

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 logout 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, the GNOME desktop can be configured to identify when a user's session has idled and take action to initiate a session lock.

Solution

Configure OL 9 to initiate a screensaver after a 10-minute period of inactivity for graphical user interfaces.

Create a database to contain the systemwide screensaver settings (if it does not already exist) with the following command:

$ sudo touch /etc/dconf/db/local.d/00-screensaver

Edit /etc/dconf/db/local.d/00-screensaver and add or update the following lines:

[org/gnome/desktop/session]

Set the lock time out to 600 seconds before the session is considered idle

idle-delay=uint32 600

Update the system databases:

$ sudo dconf update
