A word of caution, Jason... the security content in DSA is largely concerned with locking down the ESX Service Console. There's certainly a lot more to talk about in the general area of vSphere security than just that. As I've mentioned elsewhere on this board, VMware is working on a vSphere security course that covers all aspects of securing an ESX/ESXi/vCenter deployment. I'm not prepared to announce an availability date, but it's coming along nicely.

I don't say that as a way of deterring you from attending DSA, or even Mr. Pierson's "Hacking" course; just to set your expectations.
