1.35 OL09-00-000145

Information

OL 9 must not have a graphical display manager installed unless approved.

GROUP ID: V-271465
RULE ID: SV-271465r1091107

Unnecessary service packages must not be installed to decrease the attack surface of the system. Graphical display managers have a long history of security vulnerabilities and must not be used, unless approved and documented.

Solution

Remove all xorg packages with the following command:

Warning: If accessing the system through the graphical user interface, change to the multi-user.target with the following command:

$ sudo systemctl isolate multi-user.target

Warning: Removal of the graphical user interface will immediately render it useless. The following commands must not be run from a virtual terminal emulator in the graphical interface.

$ sudo dnf remove "xorg*"

$ sudo systemctl set-default multi-user.target

If there is an operational requirement for a graphical user interface it must be documented with the ISSO.
