This presentation will examine the dichotomy between the traditional secrecy-based and more modern community-based methods of information-sharing both to understand some successful forms of community-based information-sharing and demonstrate how the cybersecurity profession has changed the nature of security analysis in the real world. It concludes that absent a formal revision to the traditional mindsets embracing secrecy-based information sharing favored by the United States government and large corporate constituencies, and despite some shortcomings, a community-based approach to security analysis should become the preferred mechanism for identifying, analyzing, and resolving emerging cybersecurity concerns in a timely and effective manner.
