Check: GEN000020

SUSE Linux Enterprise Server v11 for System z STIG: GEN000020 (in versions v1 r12 through v1 r9)

Title

The system must require authentication upon booting into single-user and maintenance modes. (Cat II impact)

Discussion

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.

Check Content

Check if the system requires a password for entering single-user mode. # grep '~:S:' /etc/inittab If /sbin/sulogin is not listed, this is a finding.

Fix Text

Edit /etc/inittab and set sulogin to run in single-user mode. Example line in /etc/inittab: # what to do in single-user mode ls:S:wait:/etc/init.d/rc S ~~:S:respawn:/sbin/sulogin
