摘要
文中建立了一种基于有限状态机(Finite State Automata,FSA)的网络安全评估模型.根据网络安全模型所涉及的各种安全信息及其相关属性,用状态来表示攻防双方的安全形势;用状态迁移表征攻防双方各种行为所带来的安全形势变化;用状态转移图的形式直观地描绘出安全状态迁移过程.通过模拟攻击者入侵网络的过程和系统实现安全防御的过程,验证了该模型的有效性.
A network security evaluation model based on Finite State Automata (FSA) is proposed. According to all kinds of security information and its related properties in the model, the states are used to indicate the security situation of both attack side and defense side; the state transitions are used to indicate the dynamic security situation of the action for both attack side and defense side; the transition diagram is used to describe the transition processes of security status. Experimental results show that the model is more suitable for Network security modeling with simulating the intrusion processes of attackers and the security defense process.
