The research and design of network security evaluation systems based on cloud model

Cloud model is an effective tool for qualitative and quantitative transform, a specific structure generator is formed by normal cloud model through expectation, entropy and hyper entropy. This particular structure makes the normal cloud model has more general applicability and simply and straightforward completed conversion process between qualitative and quantitative. Since The frequency of network security incidents is nonlinear, traditional prediction methods network security incidents. which stands for the number such as ARMA and Gray systems are difficult to deal with of incidents per unit time. The cloud model used in the network security evaluation systems and the evaluation methods in the network security domain presented in this paper.
