1.6.2 Ensure SELinux is installed (Scored)

Level 2 - Server 
Level 2 - Workstation

SELinux provides Mandatory Access Controls.

Without a Mandatory Access Control system installed only the default Discretionary Access Control system will be available.

Run the following command and verify libselinux is installed:

# rpm -q libselinux 
libselinux-<version>

Run the following command to install libselinux:

# yum install libselinux

SELinux and AppArmor both have several package names in use on different distributions. Research the appropriate packages for your environment.
