Each spring, the MIS Training Institute hosts InfoSec World, an educational event that brings information security practitioners together to learn from each other. This year, volcanic fallout prevented a few participants from making the trek. But those who attended were treated to detail-rich sessions about today's biggest security threats.

Leading off

Early arrivals exchanged war stories at Sunday's CISO Executive Summit, where speakers from eBay, BT, Tyco, and UnitedHealth discussed business risks and strategies, from breach prevention and regulatory compliance to the security implications of cloud computing and social networking. As the week wound to a close, cloud security fans got down-and-dirty with VMware, desktop virtualization, and virtual pen-testing at the Summit on Secure Virtualization and Cloud Computing.

In between were a bevy of sessions and workshops, highlighted by daily keynotes. On Monday, Jeff Jonas, Chief Scientist at IBM Entity Analytics, described how new technologies are changing our lives, personally and professionally. As social and business communications merge, information about us is increasingly co-mingled, raising privacy concerns and profoundly impacting information security.

On Tuesday, Bruce Schneier, Chief Security Technology Officer at BT, elaborated with his take on data collection, privacy, and the generation gap. Specifically, Schneier argued that humanity has evolved into a complex socio-technical system where everything that we do generates data, and privacy means exerting control over data.
