Network Security under Heterogeneous Cyber-Risk Profiles and Contagion
创建于 更新于
摘要
This paper develops a Stackelberg security-game framework for cyber-risk allocation on networks, combining contagion-based risk measures and attacker/defender heterogeneous value profiles to derive (asymptotic) closed-form approximations of optimal defence allocations and scalable path-based risk metrics; numerical experiments (efficient frontiers, allocation patterns, and robustness to dynamic contagion) show targeted immunization, cyber-deception effects, and topology-dependent trade-offs between cost and systemic risk [page::0][page::18].
