Do you use SELinux?

Latest response

Coming from a long history of using Red Hat Enterprise Linux (RHEL), I have seen SELinux grow. Like many, my first entrance into it was in RHEL 4. Needless to say, I would simply disable SELinux and move on my merry way. Over the years though, I have realized the need for better host-based security methodologies, and using all the tools I can to better protect my assets. This is why I took another look at SELinux. I found many great resources through the Red Hat customer portal by searching for videos on SELinux. There are some great ones by Dan Walsh and Thomas Cameron.

 

My question for this particular discussion is "Do you use SELinux?"

 

If so, what are your impressions? If not; what are the blockers you see to implementation?
