1.6.1.2 Ensure SELinux is not disabled in bootloader configuration - selinux=0

Information

Configure SELINUX to be enabled at boot time and verify that it has not been overwritten by the grub boot parameters.

Note: This recommendation is designed around the grub bootloader, if LILO or another bootloader is in use in your environment enact equivalent settings.

Rationale:

SELinux must be enabled at boot time in your grub configuration to ensure that the controls it provides are not overridden.

Solution

Edit /boot/grub/grub.conf, or on UEFI systems edit /boot/efi/EFI/*/grub.conf, and remove all instances of selinux=0 and enforcing=0 on all kernel lines.
