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

Information

If the system does not require a valid root password 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.
NOTE: Nessus has not performed this check. Please review the benchmark to ensure target compliance.

Solution

Assign a root account password for any bootable partition.
