For decades, computer and information security research has been driven by fundamental concepts such as confidentiality, integrity, and availability. Despite the tremendous accomplishments, cybersecurity is still largely an Art. What concepts will drive the research to elevate this Art to Science of cybersecurity? Our research has led to a unique approach, dubbed Cybersecurity Dynamics, by which we aim to build a systematic foundation for modeling, analyzing, and quantifying cybersecurity from a holistic perspective. Under the umbrella of this framework, our research has been focusing on three thrusts, which we call a systematic “x-y-z-t coordinate system” as a metaphor. At a high level, the x-axis represents first-principle modeling (analogous to Theoretical Physics research for understanding the Universe), the y-axis represents data analytics (analogous to Experimental Physics research), the z-axis represents metrics (analogous to defining notions such as Mass and Energy), and the t-axis represents time (meaning that “things” in cyberspace evolve over time). The framework is inherently multidisciplinary because it cuts across many disciplines, including Computer Science, Applied Mathematics (e.g., Dynamical Systems, Control Theory, and Game Theory), Statistics, Machine Learning, Artificial Intelligence, Statistical Physics, Complexity Science, Systems Science, Network Science, and Social Sciences. In this talk, I will review the Cybersecurity Dynamics framework, highlight some results, and discuss future research directions.
