InformationThe operating system must uniquely identify and must authenticate users using multifactor authentication via a graphical user logon.
To assure accountability and prevent unauthenticated access, users must be identified and authenticated to prevent potential misuse and compromise of the system.
Multifactor solutions that require devices separate from information systems gaining access include, for example, hardware tokens providing time-based or challenge-response authenticators and smart cards such as the U.S. Government Personal Identity Verification card and the DoD Common Access Card.
SolutionConfigure the operating system to uniquely identify and authenticate users using multifactor authentication via a graphical user logon.
Note: If the system does not have GNOME installed, this requirement is Not Applicable.
Create a database to contain the system-wide screensaver settings (if it does not already exist) with the following command:
Note: The example is using the database local for the system, so if the system is using another database in '/etc/dconf/profile/user', the file should be created under the appropriate subdirectory.
# touch /etc/dconf/db/local.d/00-defaults
Edit '[org/gnome/login-screen]' and add or update the following line:
Update the system databases:
# dconf update
