Cyber economics drives many of the decisions related to cybersecurity by both the defenders and attackers. It determines on the defensive side the technologies and procedures implemented to prevent and respond to cyber-attacks. On the offensive side, it not only determines the type of attack but also the effort expended to ensure its success. In short, it determines the asymmetric balance between the attackers and defenders. The Cyber Resiliency Economics workshop will explore effects of cyber economics on this asymmetric balance and examine approaches to shifting adversaries’ current advantage in cyber conflicts in favor of defenders. It will bring together a diverse group of experts to advance the concepts and application of cyber economics as related to asymmetric advantage and cyber resiliency. This includes foundational and applied advances in economics, its effects on asymmetry and resiliency driving the essential system requirements for cyber systems including traditional IT, cloud platforms, cyber-physical systems, and critical infrastructure. This will serve to accelerate the recognition, adoption and application of cyber security resilience within industry, government and academia by addressing the key concerns of how these techniques and technologies can be realized within the practical constraints of cost, risk, and benefit.
