Fix Recommendation

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

Check Contents

Note: This requirement assumes the use of the AlmaLinux OS 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 AlmaLinux OS 9 prevents a user from overriding the disable-restart-buttons setting for graphical user interfaces.

Determine which profile the system database is using with the following command:

$ grep system-db /etc/dconf/profile/user

system-db:local

Check that graphical settings are locked from nonprivileged user modification with the following command:

Note: The example below is using the database "local" for the system, so the path is "/etc/dconf/db/local.d". This path must be modified if a database other than "local" is being used.

$ grep disable-restart-buttons /etc/dconf/db/local.d/locks/*

/org/gnome/login-screen/disable-restart-buttons

If the command does not return at least the example result, this is a finding.
