Files from HITB (Hack In The Box) 2004 Presentation by Theo de Raadt: "Exploit Mitigation Techniques". Description from HITB: OpenBSD has been auditing software for nearly 10 years, and while we have had significant success, it is clearly not enough. In the last 3 years a new view on preventing attacks has surfaced in the mindset of our group. A software exploit author starts by finding an interesting bug. Writing an exploit is easy because he can rely on a variety of system behaviours which are very deterministic. Many of these behaviours are not required for proper operation. Recently we have developed many new techiques which combine to thwart the attacker, without affecting regular software. We make the Unix process environment difficult to attack much like filling a house full of a variety of burglar traps.
