The system must use a Linux Security Module configured to enforce limits on system services.
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. However, McAfee Endpoint Security for Linux (ENSL) is an approved alternative to both McAfee Virus Scan Enterprise (VSE) and HIPS. In either scenario, SELinux is interoperable with the McAfee products and SELinux is still required.
