A New Look at Cyber Defense: Blending Insights from Computer Science, Health Science, and Operations Research

Arthur Pyster, Ph.D.
Federal Aviation Administration (FAA)
About the talk:

Early approaches to information systems security, such as that articulated in Presidential Decision Directive 63, encouraged agencies to protect their networks primarily by hardening individual network nodes. Over the past few years, cyber threats have grown enormously. Vulnerabilities are being exploited ever more rapidly. New technologies to defend networks are being delivered by the commercial marketplace daily. New approaches that recognize this dynamic environment are needed. With two million passengers daily depending on FAA network operations for safe flight, the FAA has developed a sophisticated approach to secure its network from cyber attack. That approach integrates architecture simplification, element hardening, boundary protection, systemic monitoring, orderly quarantine, and informed recovery. The talk will provide insight into that approach and the challenges that the FAA faces in navigating the rapidly changing landscape of cyber security.
