Abstract�� Applying the methodologies of game theory and network security, considering the decision interdependence of the players, a game model of intrusion response based on cost analysis was presented. The study showed the optimal strategies for the players in the deployment of security technique-Intrusion Detection System(IDS), discussed the Nash equilibrium solutions, and verified the model rationality by cost-analysis from the theoretic and empirical aspects. Focusing on the problem of intrusion response without considering cost now, the model was introduced damage cost and response cost. With comparison with the two kinds of cost, the conditional cost of responding was analyzed, thus an adaptive intrusion response strategy to system administrator was made. This method can illustrate the response policy of system administrator in the actual decision further, improve security and avoid wasting unnecessary resource, then achieve the balance between information protection and resource.
