1.8.1 Ensure GNOME Display Manager is removed

Information

The GNOME Display Manager (GDM) is a program that manages graphical display servers and handles graphical user logins.

Rationale:

If a Graphical User Interface (GUI) is not required, it should be removed to reduce the attack surface of the system.

Impact:

Removing the GNOME Display manager will remove the GUI from the system.

Solution

Run the following command to remove the gdm package

# yum remove gdm
