OpenBSD has: Memory protection purify * W^X * .rodata segment * Guard pages * Randomized malloc() * Randomized mmap() * atexit() and stdio protection In grsecurity there is PaX: http://pax.grsecurity.net/ Can these features really prevent some exploits? I tried to search equivalants in FreeBSD. Greetings Willem Hendriks
