Here is a fun podcast a bunch of us (yes, including Chris, of course!) did on security, logging and virtualization (audio, full transcript).
It is actually a fun read / listen, if you are into either/all of these three :-)
Here is the brief blurb on that from the podcaster site: "To help learn about new ways that systems log tools and analysis are aiding the ramp-up to virtualization use, I [Dana Gardner] recently spoke with Charu Chaubal, senior architect for technical marketing, at VMware; Chris Hoff, chief security architect at Unisys, and Dr. Anton Chuvakin, chief logging evangelist and a security expert at LogLogic."
