Study of Two Kinds of Analysis Methods of Intrusion Tolerance System State Transition Model

Received: 11 January 2019 Accepted: 20 February 2019 The existing network security technologies cannot prevent all of intrusion, so the purpose of this study is to ensure that the system can continue to operate normally after the invasion. On the basis of existing intrusion tolerance model, increased to learning Status, the optimal state transition model of the invasion-tolerant system is proposed and analyzed respectively with the theory of finite automata and markov theory, further establish intrusion tolerance system. The experimental results show that increasing the learning state can enhance the tolerance of the system and ensure the stable operation of the system. The significance of this study is to provide a new idea for intrusion tolerance technologies.
