Introducing SELinux and auditd


During the course of this chapter, we'll explore the SELinux framework for Linux and see how to automate it using Puppet.

Using Puppet, we can automate the configuration of these often-neglected security tools, and even move the configuration of these tools for various services to the modules that configure those services.
