Abstract. Organizations and their computer infrastructures have grown intertwined in complex relationships through mergers, acquisitions, reorganizations, and cooperative service delivery. Consequently, defensive actions and policy changes by one organization may have far-reaching negative consequences on the partner organizations. Human-centric and machine-centric approaches are insufficient for defending the security of today's increasingly complex computer infrastructures. The former are slow but highly adaptive, while the latter are fast but highly specialized. We believe the solution lies in mixed-initiative defenses combining the complementary qualities of both human- and machine-based approaches. We describe the Cooperative Infrastructure Defense (CID), a new cyberdefense paradigm designed to unify complex-adaptive swarm intelligence, logical rational agents, and human insight. CID will enable cooperative defense of infrastructure through situational awareness using visualization, security policy dialogue between humans and agents, shared initiative in solving cyber problems, and a foundation for building trust between humans and agents within and between organizations.
