We have been trying to create secure computer systems for thirty plus years without success. This suggests that perhaps we are doing it wrong. This presentation looks at cyber operations and risk from cybercrime, cyber espionage, and cyber warfare through the lens of cyber intelligence. It addresses what lessons can be learned from cyber space as a domain of war and the implications of chaos, complexity and non-linear science, with specific examples. It focuses on proactive cyber defense rather than reactive. Assuming that computer systems cannot be made completely secure, how does one implement a dynamic defense dependent on the adversary's intentions?
