While the notion of "players," "actions," and "payoffs" may seem more suited to Las Vegas gaming tables, game theory as a mathematical tool has steadily grown in cyber defense applications. In ongoing and progressive work being conducted under PNNL's Asymmetric Resilient Cybersecurity initiative, scientists have taken on the challenge of addressing the sources and types of uncertainty that can arise in realizing a resilient cyber system. Already, their work on quantifying uncertainties in cyber attacker payoffs within randomly determined security games has been recognized with an IEEE Best Paper award. Meanwhile, their latest publication presents a probabilistic modeling framework for representing and propagating uncertainties in cyber attacker payoffs with the added goal of increasing awareness among researchers about this problem domain.
