The mission of the Laboratory for Cybersecurity Dynamics is to systematically explore the notion/abstraction of Cybersecurity Dynamics as the Foundation for the ultimately-wanted Science of Cyber Security. We believe Cybersecurity Dynamics is the right abstraction because it not only can deepen our understanding/knowledge, but also can guide the practice of cyber defense operations (including quantitative risk-management and decision making). We are fully aware of the gaps we must bridge as well as the inherent technical barriers we must tackle. We see tons of opportunities for researchers crossing multiple disciplines, crossing multiple sub-disciplines within Computer Science, and crossing the already established various security sub-fields, to closely work together. We look forward to collaborations, and we believe the way ahead is exciting!!
