Setting the SELinux state to enforcing ensures SELinux is able to confine potentially compromised processes to the security policy, which is designed to prevent them from causing damage to the system or further elevating their privileges. Per OPORD 16-0080, the preferred intrusion detection system is McAfee Host Intrusion Prevention System (HIPS) in conjunction with SELinux.

In either scenario, SELinux is interoperable with the McAfee products and SELinux is still required.
