Fix Recommendation

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

Check Contents

This requirement assumes the use of the OL 9 default graphical user interface—the GNOME desktop environment. If the system does not have any graphical user interface installed, this requirement is Not Applicable.

Verify OL 9 initiates a session lock after a 10-minute period of inactivity for graphical user interfaces with the following command:

$ gsettings get org.gnome.desktop.session idle-delay
uint32 600

If "idle-delay" is set to "0" or a value greater than "600", this is a finding.
