Subject: SELinux vs. AppArmor vs. Standard vs. What?
Thanks for all the responses to my remote desktop login question. I'm
pretty sure we will deploy FreeNX for that function.

This question has to do with the same server. A tech savvy manager
says we should use "NSA Linux" on the remote desktop host server.
What he means is use the SELinux security features.

Now, I don't have lots of experience with setup and maintainence of
SELinux. I hAve read that it is painful and requires more
administration than just "set and forget."

A similar technology is the AppArmor profiles for applications. Said
to be easier to use than SELinux but provides much the same benefits.

Then a third camp seems to think that both of these are overkill and a
headache for the benefits gained. They feel that, configured
correctly, standard user security on a Linux box is secure enough for
most business applications.

Where do any of you stand on this argument? Is SELinux really a pain
to setup and use? Is AppArmor interesting but not worth it?

Given the function of the server as I previously described in that
other thread (http://lists.plug.phoenix.az.us/lurker/thread/20081030.230820.05346d48.en.html#20081030.230820.05346d48),
What security extensions would you deploy and why?
