Fix Recommendation

Configure RHEL 9 to display the Standard Mandatory DOD Notice and Consent Banner before granting access to the system via a graphical user logon.

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

$ sudo touch /etc/dconf/db/local.d/01-banner-message

Add the following lines to the [org/gnome/login-screen] section of the "/etc/dconf/db/local.d/01-banner-message":

[org/gnome/login-screen]

banner-message-enable=true

Run the following command to update the database:

$ sudo dconf update

Check Contents

Verify RHEL 9 displays the Standard Mandatory DOD Notice and Consent Banner before granting access to the operating system via a graphical user logon.

Note: This requirement assumes the use of the RHEL 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.

Determine if the operating system displays a banner at the logon screen with the following command:

$ gsettings get org.gnome.login-screen banner-message-enable

true

If the result is "false", this is a finding.
