2. Using Gentoo/Hardened SELinux

With the theoretic stuff behind us, let us start by installing Gentoo/Hardened with a SELinux kernel as well as the SELinux tools.

Content:

  1. Gentoo SELinux Installation / Conversion
    To set up SELinux within Gentoo/Hardened, you first need to install Gentoo with the correct Hardened profile (or convert to the Hardened profile) and then update your system to become a SELinux-managed system. This chapter will guide you through this process.
  2. Configuring SELinux For Your Needs
    With SELinux now "installed" and enabled (although in permissive mode), we now configure it to suit your particular needs. After all, SELinux is a Mandatory Access Control system where you, as security administrator, define what is allowed and what not.
  3. SELinux Commands
    Let's take a step back and get to know a few more commands. We covered most of them in the previous section, but we will now dive a bit deeper in its syntax, features and potential pitfalls.
  4. Permissive, Unconfined, Disabled or What Not...
    Your system can be in many SELinux states. In this chapter, we help you switch between the various states / policies.
  5. Modifying the Gentoo Hardened SELinux Policy
    Gentoo Hardened offers a default policy, but this might not allow what you want (or allows too much). In this chapter we tell you how you can tweak Gentoo's policy, or even run your own.
  6. Troubleshooting SELinux
    Everything made by a human can and will fail. In this chapter we will try to keep track of all potential issues you might come across and how to resolve them.
  7. Change History
    As documentation evolves with the technology, this handbook too sees its fair share of changes. To allow users, who are already on SELinux, to verify if there are any changes they need to be aware off, this chapter lists the changes in chronological order.
