SELinux Coloring Book (Actually useful, from Red Hat)

SELinux can seem a lot to learn, but this SELinux coloring book by Red-Hatter Dan Walsh explains it quite plainly.

    Learn the basics of SELinux, including type enforcement, Multi-Category Security (MCS) Enforcement, and Multi-Level Security (MLS) Enforcement, with the help of some friendly cats and dogs!

Also, go to youtube, and type in "SELinux for Mere Mortals" and look for a Red Hat video from 2018. I'll attempt to find the slides and post them later. Right now the link I know of is not working
