SELinux
I figured I'd like to get some better knowledge on IT security.
I've got already some good practices that I've got refined over time. GPG, private-key only authentication via SSH, using a browser as little as possible (and with extensions like NoScript or CookieSelfDestruct), just to name a few. Plus another ton of habits for the privacy side, that are out of topic here.
I'd like to focus on SELinux, after some discussions. A good starting point is to use it for securing what I perceive as my weakest spot: (obviously) the browser.
I'd like to keep a journal about my SELinux exploration, since my perception is it's a somewhat difficult thing to work with. I can't guarantee I'll be able to write everything I find, as writing takes time, and time is valuable for learning (which one of the reasons why I seldom write on this site).
