Details
| Check Text (C-23414r419169_chk) |
| Verify the operating system must require authentication upon booting into single-user and maintenance modes. Check that the operating system requires authentication upon booting into single-user mode with the following command: # grep -i execstart /usr/lib/systemd/system/rescue.service | grep -i sulogin ExecStart=-/bin/sh -c "/usr/sbin/sulogin; /usr/bin/systemctl --fail --no-block default" If "ExecStart" does not have "/usr/sbin/sulogin" as an option, this is a finding. |
| Fix Text (F-23403r419170_fix) |
| Configure the operating system to require authentication upon booting into single-user and maintenance modes. Add or modify the "ExecStart" line in "/usr/lib/systemd/system/rescue.service" to include "/usr/sbin/sulogin": ExecStart=-/bin/sh -c "/usr/sbin/sulogin; /usr/bin/systemctl --fail --no-block default" |
