Best? Well what do you want to do? How much time are you prepared to
spend to secure your system?
Are you looking for a general, basic security model (Openwall works good
and is easy to apply) or do you want to spend time on ACLs (SELinux or
RSBAC or Grsecuritys simple system)?

Good is you just want to apply it and basically forget about it.

Is not a kernel patch. Now called Adamantix (have a look at www.adamantix.org) and is a Debian deriviate that uses PaX, builds every package (including the kernel) with IBMs stack smashing protector and lets you choose if you want to use an RSBAC (www.rsbac.org) enabled kernel.

And RSBAC, SELinux to the list if you want to check similar patches out.

or wait for .22 which _might_ include some crypto.

... and don't forget to build the packages with your SSP patched GCC :)
