Fix Recommendation

Configure the operating system to verify correct operation of all security functions.

Set the "SELinux" status and the "Enforcing" mode by modifying the "/etc/selinux/config" file to have the following line:

SELINUX=enforcing

A reboot is required for the changes to take effect.

Check Contents

Per OPORD 16-0080, the preferred intrusion detection system is McAfee Host Intrusion Prevention System (HIPS) in conjunction with SELinux. McAfee Endpoint Security for Linux (ENSL) is an approved alternative to McAfee Virus Scan Enterprise (VSE) and HIPS. For Oracle Linux 7 systems, SELinux is an approved alternative to McAfee HIPS. Regardless of whether or not McAfee HIPS or ENSL is installed, SELinux is interoperable with both McAfee products and SELinux is still required.

Verify the operating system verifies correct operation of all security functions.

Check if "SELinux" is active and in "Enforcing" mode with the following command:

# getenforce
Enforcing

If "SELinux" is not active and not in "Enforcing" mode, this is a finding.
