基于博弈分析的入侵容忍决策研究

入侵风险和响应成本是入侵容忍决策的重要因素。通过对信息系统的性能、风险与响应代价等要素进行博弈推理,理论分析了入侵容忍决策问题,指出了当响应成本大于容忍代价时,系统选择容忍策略;反之,则选择混合策略,即可获取最大的收益,对于入侵容忍决策具有一定意义。

Decision Analysis of Intrusion Tolerant System Based on Game Theory

Intrusion risk and cost of countermeasure are two important factors for decision making of intrusion tolerant system.Theoretic analysis on decision making is performed through game deduction with performance,risk and cost of countermeasure.It demonstrates that the tolerant system should choose silent tactic under heavy response cost while choose mixed strategy for small cost.The research is important for decision making research of intrusion tolerant system.
