Bruce Schneier: Reconceptualizing Security
Augustus Ballroom 3-4
About: Security is both a feeling and a reality. You can feel secure without actually being secure, and you can be secure even though you don't feel secure. We tend to discount the feeling in favor of the reality, but they're both important. The divergence between the two explains why we have so much security theater, and why so many smart security solutions go unimplemented. Several different fields-behavioral economics, the psychology of decision making, evolutionary biology-shed light on how we perceive security, risk, and cost. It's only when the feeling and reality of security converge that we have real security.
