While computer science is not traditionally viewed as a social science, problems in its domain are inherently social in nature ‐ relating to people, their interactions and the relationships between them and their organizational contexts. The broad scope of the field of "security engineering" and increasing recognition that economics and psychology are integral parts of security are good examples of this, but only begin to scratch the surface. We will present this unexpected new lens and examine the two areas of economics and psychology in security, extracting insights and generalizing concepts to help attendees understand how these perspectives might be useful in their own roles. Sarah Blankinship will introduce the perspective and explain its application in the Microsoft security ecosystem over the last few years. Sarah is a Senior Security Strategist, an 'EcoStrategist', leading the Security Ecosystem Strategy team within the Microsoft Security Response Center (MSRC) to engage security communities from around the world to research and respond to software vulnerabilities. Jon Pincus will apply the similar perspective of social science theories to the field of static analysis as it relates to security. Jon's return to static analysis (he was architect of PREFix and PREfast from 1995‐2001) provides an opportunity for unique perspective, highlighting where progress has been made, where it hasn't, and identifying remaining barriers to pervasive deployment of static analysis tools ‐‐ in particular, user interface challenges for defect understanding and work‐in‐context. Developments in disciplines like "gender HCI" and captology may offer paths forward. At the same time, efforts like SAMATE and Coverity's Scan are building the social infrastructure to the community as a whole to follow the lead of the security research community and incorporate an explicit ecosystem focus. The important theme to discuss is opportunities for shared goals and cooperation from organizations and people usually seen as rivals: security researchers and software engineers, developers and security auditors, employees of bitter competitors. In many situations, well‐chosen "teams of rivals" strategies ‐‐ while easy to overlook ‐‐ offer substantial benefits and positive‐sum outcomes. We'll close the session by showing how to apply this approach to several timely challenges in the computer security field.
