"This Fall, Microsoft hosted the second annual Blue Hat conference on Campus. The audience was primarily Microsoft employees who write code, as well as executives from around the company. Security Researchers (which is what they prefer to be called) came to the Microsoft Castle and showed us their latest findings and shared with our engineers the lastest threats, trends, and general things to watch out for in the wide world of hacking. In this part of the three part series, we talk to Andrew Cushman a Security Architect. He tells us what Blue Hat is, what and who it's for, and why we were hosting a bunch of Security Researchers at Microsoft"

This well worth checking out... getting security researchers to Redmond to outline new attack techniques (and in some cases, defense techniques!) is well worth it... there is nothing quite like watching your security assumptions get torn apart!
