In this work, we propose a probabilistic value-passing CCS (Calculus of Communicating System) approach to model and analyze a typical network security scenario with one attacker and one defender. By minimizing this model with respect to probabilistic bisimulation and abstracting it through graph-theoretic methods, two algorithms based on backward induction are designed to compute Nash Equilibrium strategy and Social Optimal strategy respectively. For each algorithm, the correctness is proved and an implementation is realized. Finally, this approach is illustrated by a detailed case study.
