Many methods and the models have been raised, and established the defense mechanism to resist the external threat. But in the few years, it is taken seriously gradually to the research about the internal threat. Many researchers consider that the problem of internal threat can not to neglect. The human factor is the biggest reason to the internal threat. We referred to formerly the analysis method and consider the internal threat factor. We simultaneously consider the external threat and the internal threat factor, and define the weight that according the different harm of the internal threat and the external threat. And according these conditions, we use game theory model to calculate the probability of the attack.
