A good solution, not too hard to implement, is to patch your kernel with
Grsecurity provides a very good level of protection against buffer overflow
It randomizes PIDs, it protects chroots, enforces the TCP/IP stack, etc.
Grsecurity is actually a cumulative patch from Pax, some OpenBSD TCP/IP
into linux, openwall, HAP-linux.
Btw it is very configurable, and pretty well documented, at configuration
I use it and am very happy with it. If I trust archives from this list, I am
the only one in this case :-)
