Fix Recommendation

Configure AlmaLinux OS 9 to prevent a user being able to override the GNOME banner setting by running the following commands:

$ echo "banner-message-enable" | tee /etc/dconf/db/local.d/locks/00-banner > /dev/null

$ dconf update

Check Contents

Note: This requirement assumes the use of the 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 disabling the banner for graphical user interfaces.

Determine if the operating system prevents modification of the GNOME banner setting with the following command:

$ grep banner-message-enable /etc/dconf/db/local.d/locks/*

banner-message-enable

If "banner-message-enable" is commented out or is missing, this is a finding.
