Fix Recommendation

Configure OL 9 to initiate a session lock for graphical user interfaces when a screensaver is activated.

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

Note: The example below is using the database "local" for the system, so if the system is using another database in "/etc/dconf/profile/user", the file should be created under the appropriate subdirectory.

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

[org/gnome/desktop/screensaver]
lock-delay=uint32 5

The "uint32" must be included along with the integer key values as shown.

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 that OL 9 initiates a session lock for graphical user interfaces when the screensaver is activated with the following command:

$ gsettings get org.gnome.desktop.screensaver lock-delay
uint32 5

If the "uint32" setting is not set to "5" or less, or is missing, this is a finding.
