Submission + - Theo de Raadt gives a 10-year summary on exploit mitigation in OpenBSD
ConstantineM writes: Microsoft has all significant exploit mitigation techniques fully integrated and enabled, claims Theo de Raadt at Yandex ruBSD, whilst giving a 10-year summary of the methods employed by OpenBSD. In year 2000, OpenBSD started a development initiative to intentionally make the memory environment of a process less predictable and less robust, without impacting the well-behaved programs. Concepts like the random stack gap, W^X, ASLR and PIE are explained. Some of them, like the random stack gap, are implemented with a 3-line change to the kernel, yet it appears that some other vendors are still shipping without it.
