kernel - Kernel parameters

The Linux kernel has many parameters that can improve overall system security and most of these parameters can be changed while a system is running.

Overview

The security role applies several changes to kernel parameters and each of these changes are controlled by Ansible variables. Review the ## Kernel settings section within defaults/main.yml file for more information on these changes.

One deviation appears in this section for IP forwarding. Review the documentation for V-72309 below for more details.
