By now, many of you have heard us speak about or have read our writings on the improved security capabilities of Windows Vista. As I've said at a number of events now, the research I've done into these capabilities has convinced me that enterprises should seriously consider Vista upgrades. This OS is really gonna make the bad guys rethink their tactics.
My friend Jeff Jones has recently dug into the differences in 64-bit Windows Vista. In his first article he describes hardware no execute protection. His second article explores Patchguard, explains its value, and deflates some recent research into bypassing Patchguard.
If you haven't been reading Jeff's blog, I recommend adding it to your list of feeds.
