Fix Recommendation

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

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

Check Contents

Check to see if the system requires authentication for rescue or emergency mode with the following command:

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

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

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