1.10 OL09-00-000020

Information

OL 9 must be configured so that the graphical display manager is not the default target unless approved.

GROUP ID: V-271440
RULE ID: SV-271440r1092462

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

Configure OL 9 to boot to the command line.

Set the default target to multi-user with the following command:

$ sudo systemctl set-default multi-user.target

If there is an operational requirement for a graphical user interface, document it with the ISSO.
