Check Text (C-51976r779190_chk)

Determine if the system requires authentication for emergency mode with the following command:

$ sudo grep sulogin-shell /usr/lib/systemd/system/emergency.service

ExecStart=-/usr/lib/systemd/systemd-sulogin-shell emergency

If the "ExecStart" line is configured for anything other than "/usr/lib/systemd/systemd-sulogin-shell emergency" or is commented out or missing, this is a finding.

Fix Text (F-51930r779191_fix)

Configure the system to require authentication upon booting into emergency mode by adding the following line to the "/usr/lib/systemd/system/emergency.service" file:

ExecStart=-/usr/lib/systemd/systemd-sulogin-shell emergency
