1.6.1.2 Ensure SELinux is not disabled in bootloader configuration - selinux

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 2 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 /etc/default/grub and remove all instances of selinux=0 and enforcing=0 from all CMDLINE_LINUX parameters:

GRUB_CMDLINE_LINUX_DEFAULT='quiet'

GRUB_CMDLINE_LINUX=''

Run the following command to update the grub2 configuration:

# grub2-mkconfig -o /boot/grub2/grub.cfg
