Title

RHEL 9 must disable the ability of systemd to spawn an interactive boot process.

Control

Verify that GRUB 2 is configured to disable interactive boot. Check that the current GRUB 2 configuration disables the ability of systemd to spawn an interactive boot process with the following command: $ sudo grubby --info=ALL | grep args | grep 'systemd.confirm_spawn' If any output is returned, this is a finding.

Discussion

Using interactive or recovery boot, the console user could disable auditing, firewalls, or other services, weakening system security.
