Description
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.
ℹ️ Check
Verify TOSS 5 is configured to boot to the command line:
$ systemctl get-default
multi-user.target
If the system default target is not set to "multi-user.target" and the information system security officer (ISSO) lacks a documented requirement for a graphical user interface, this is a finding.
✔️ Fix
Document the requirement for a graphical user interface with the ISSO or set the default target to "multi-user" using the following command:
$ sudo systemctl set-default multi-user.target
