What is grsecurity2/AppArmour/SElinux?
I think I have security down-pat, but I'm not sure about grsecurity2/AppArmor/SElinux. I mean, I know what they all do, but I have two main questions:
1. If I install grsecurity2, do I need to enable AppArmor/SElinux?
2. Do I need to run both AppArmor and SElinux or just one?
Also, what about buffer overrun protection? I hear Ubuntu has its own software enabled by default, but I'v also heard that I need more protection than that. Any answers?
