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