| If the system is a cross-domain system, this is not applicable. Inspect "/etc/grub.conf" for any instances of "selinux=0" in the kernel boot arguments. Presence of "selinux=0" indicates that SELinux is disabled at boot time. If SELinux is disabled at boot time, this is a finding. |
| Fix Text (F-RHEL-06-000018_fix) |
|---|
| SELinux can be disabled at boot time by an argument in "/etc/grub.conf". Remove any instances of "selinux=0" from the kernel arguments in that file to prevent SELinux from being disabled at boot. |
