Details

Disabling a major host protection feature, such as SELinux, at boot time prevents it from confining system services at boot time. Further, it increases the chances that it will remain off during system operation.

Solution

SELinux can be disabled at boot time by an argument in ‘/boot/grub/grub.conf’. Remove any instances of ‘selinux=0’ from the kernel arguments in that file to prevent SELinux from being disabled at boot.
