%X <p>A security evaluation based on network entropy and stochastic game was presented. An attack defense stochastic game model was proposed to describe the conflict of network security which is dynamic and multi-state. The concept of network entropy was introduced to describe network security performance. The optimal defense strategy and network state probability was obtained by solving the Nash equilibrium of attack defense stochastic game model. On this basis, the security of network was assessed combining with network states entropy difference. Network security evaluation algorithm was given at last. An example is representatively provided to show that the method can effectively assess the security of network and predict intrusion behavior.</p>
