GEN000020 - The system must require authentication upon booting into single-user and maintenance modes.

Information

If the system does not require valid root authentication before it boots into single-user or maintenance mode, anyone who invokes single-user or maintenance mode is granted privileged access to all files on the system.

Solution

Edit /etc/inittab and set sulogin to run in single-user mode.
Example line in /etc/inittab:
~:S:wait:/sbin/sulogin

Note: The first field in the /etc/inittab line may be any sequence of 1-4 characters.
