I have a question. With the sheer number of Windows components each having objects whose security and inheritability can be manipulated individually, and with tokens and privileges controlling access on top of that, and with so many users and groups to account for, and with so many special cases for consoles etc. to consider, I'm surprised at how few of these bugs there seem to be. It seems like a herculean feat to track everything for even just a single version of the kernel, let alone in an ever-evolving entire OS. Do you know how Microsoft keeps track of all the security barriers, interactions, etc. in the entire OS? Do they have entire teams dedicated to just tracking the security privileges/permissions/etc. for all the components?
