Mimic Defense System Security Analysis Model

In this article, the mimic defense technology based on dynamic heterogeneous redundancy architecture is studied, and the mimic defense system is described formally to improve the proactive defense capability of information systems and key equipment in the network. A method integrating dynamic feature, heterogeneous feature and redundant feature that carries out security analysis of mimic defense system by probabilistic analysis is proposed for the lack of effective security assessment method about mimic defense system. Vali-dated by simulation experiments simulating the attacker and the mimic defense system, this model can calculate the safety of the mimic defense system according to the attack factor, heterogeneity degree, dynamic transformation and other related factors. According to the research results, the proposed model is of certain guiding significance for helping designers to construct mimic defense system.
