Welcome to lesson 27.
This important lesson is about SELinux.
I'll start by explaining why it is needed and how it uses security labels, after which
we'll explore the different SELinux modes.
Next we'll learn about the different components that matter while working with SELinux, which
is followed by a discussion of file context labels.
I'll give you some tricks to find the right context, and after that you'll learn how to
manage port access and how to use booleans.
And then we'll get into SELinux log messages and troubleshooting.
At the end of this lesson you'll find the lab as well as the lab solution.
