Yeah; I know the last thing this blog needs is yet another article that trashes Vista security posted. Yet I thought this one had merit because it puts most of the problems known to exist in one short and succinct article. Plus, it relies in large part on Joanna Rutkowska and Mark Russinovich for sources. Those two are among the greatest experts on Windows security.
They don't agree. Russinovich takes the position that Vista's User Account Control (UAC) is a big step in the right direction. There is no real detail in the article, but at least most of the objections and their counters are in one place.
