Research on Network Security Situation Measurement Method Based on Game State Model for Network Countermeasures

It is necessary to describe the network countermeasure process abstractly for network security situation measurement and improving prediction capability and defense activity.Due to the complexity,ambiguity and indefiniteness of the network states and information access ways,it is extremely difficult to construct an effective network countermeasure model.A novel network countermeasure model which is more applicable is developed applying game theory and definite state machine theory.Based on the model,the security situation measurement model is given to calculate the security risk according to the security attributions.With the above models,users can recognize the attack intents and give system security risk.
