One question: I have been thinking about installing linux-patch-grsecurity2 from Debian repos. However, I am afraid that it might break apparmor work, or even stop the OS from functioning. Does anyone know if that would be the case?
Also, would installing that patch be enough to improve somehow the security, or would it be necessary to go through a hard configuration process??
THANKS
