Fix Recommendation

Configure RHEL 10 to prevent a user from overriding settings for graphical user interfaces.

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

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

Update the "/etc/dconf/db/local.d/locks/session" file to prevent nonprivileged users from modifying the screensaver lock:

$ sudo vi /etc/dconf/db/local.d/locks/session

/org/gnome/desktop/screensaver/lock-enabled

Run the following command to update the database:

$ sudo dconf update

Check Contents

Note: This requirement assumes the use of the RHEL 10 default graphical user interface, Gnome Shell. If the system does not have any graphical user interface installed, this requirement is not applicable.

Verify RHEL 10 prevents a user from overriding the screensaver lock-enabled setting with the following command:

$ gsettings writable org.gnome.desktop.screensaver lock-enabled
false

If "lock-enabled" is writable, and the result is "true", this is a finding.
