Thank you so much for all that. I took a great introductory Linux course by the Linux Foundation over at edx[0] which really filled me in on a lot of stuff about Linux one misses out on when they learn on their own. Sadly, the subsequent Linux Foundation training courses are way out of my price range. Even the intro course offered I took for free on edx is offered by the Linux Foundation for thousands of dollars. The good thing is I can mostly learn stuff on my own but have a hard time figuring out what I should be learning. Your comment helps a lot on that department. Even if I don't quite understand how to do some of the stuff your saying e.g. segment the network? Sandbox? Isn't eth0 my primary port to connect to my server? Which logs should I be monitoring (I've only heard of auth.log)? Thanks.
