The SELinux Notebook

Many of you reading this are likely already aware of “The SELinux Notebook” by Richard Haines. For those of you who have not seen it before, “The SELinux Notebook” is a very comprehensive guide to SELinux that stretches from the kernel all the way up through the policy. It’s really an impressive work, made even more impressive by the fact that Richard has been kind enough to make it freely available.

In the latest 5th edition, Richard opened the book even more by converting it into Markdown and posting the book, in source form, on GitHub. This is a tremendous gift to the SELinux community, and one that I hope we will not squander. My hope is that we can turn “The SELinux Notebook” into a living document that is updated along with the code and the policies so that it continues to be the excellent resource that it is today.
