Title

RHEL 10 must not have the "gdm" package installed.

Control

Verify RHEL 10 does not have the "gdm" package installed with the following command: $ sudo dnf list --installed gdm Error: No matching Packages to list If the "gdm" package is installed and the need for a GUI interface has not been documented with the information system security officer, this is a finding.

Discussion

Unnecessary service packages must not be installed to decrease the attack surface of the system. A graphical environment is unnecessary for certain types of systems including a virtualization hypervisor.
