Information
AlmaLinux OS 9 must prevent a user from overriding the disable-restart-buttons setting for the graphical user interface.
GROUP ID: V-269280
RULE ID: SV-269280r1050162
A user who is at the console can reboot the system at the login screen. If restart or shutdown buttons are pressed at the login screen, this can create the risk of short-term loss of availability of systems due to reboot.
Solution
Configure AlmaLinux OS 9 to prevent a user from overriding the disable-restart-buttons setting for graphical user interfaces.
Create a database to contain the systemwide graphical user logon settings (if it does not already exist) with the following command:
$ touch /etc/dconf/db/local.d/locks/session
Add the following line to prevent nonprivileged users from modifying it:
/org/gnome/login-screen/disable-restart-buttons
Run the following command to update the database:
$ dconf update
