I definitely need to get to the Black Hat conference next year. It was just a few weeks back in Vegas and it looked to have a ton of good sessions. One of my absolute favorite bloggers, Christofer Hoff, was nice enough to post the slides from his session on "The Four Horseman of the Virtualization Security Apocalypse". Although, as he points out, the slides are meant to go with his speaking, I went through all 176 slides and it was AWESOME!! I highly recommend anyone interested in virtualization, security....or otherwise take a minute to read through his presentation.
Check out his blog and the presentation PDF here.
