Check Text (C-269136r1137691_chk)
Verify that AlmaLinux OS 9 requires authentication for emergency mode with the following command:
$ grep -E 'ExecStart.*sulogin' /usr/lib/systemd/system/emergency.service
ExecStart=-/usr/lib/systemd/systemd-sulogin-shell emergency
If this line is not returned, or is commented out, this is a finding.
If the output is different, this is a finding.
Fix Text (F-73068r1049172_fix)
Configure AlmaLinux OS 9 to require authentication for emergency mode.
Add or modify the following line in the "/usr/lib/systemd/system/emergency.service" file:
ExecStart=-/usr/lib/systemd/systemd-sulogin-shell emergency
"sudo systemctl edit emergency.service" can also be used to create a "/etc/systemd/system/emergency.service.d/override.conf" file.
