The 6/28 Virtualization Security Podcast we spoke about attacks, defense in depth, and compliance with Davi Ottenhiemer and Matt Wallace. Davi and Matt just published a book (available on the Virtualization Bookshelf under Security) on how to defend your virtual environment against attack. Unlike other books, this approaches the problem from the point of view of well know attacks. It even gives examples of some of the more interesting attacks against any of the virtual environments, not just VMware vSphere. The discussion eventually found its way to even newer attacks and their impact on the environment.
