Dave Tyson literally wrote the book on Managing Enterprise Security Risk through converged security  while serving as the CSO for the City of Vancouver during the winter Olympic games.  A practitioner rather than a theorist, Tyson has held senior security leadership positions at multiple major organizations including eBay, Pacific Gas and Electric and SC Johnson. In this episode Dave Tyson discusses the origins of security convergence, why organizations need to explore this now more than ever and how to gain support with the executive suite by identifying and removing value chain friction created by security processes.
