The existing mechanisms in selecting response strategies only take into account the single factor from the defenders' point of view,not consider the impact of the attackers' strategies and behaviors.To select reasonably active response strategies,this paper evaluated the benefits and costs of both attackers and defenders based on their game model,and proposed a double population based immune co-evolutionary algorithm to select the active response strategies,aiming to maximize benefits and minimize costs for both attackers and defenders.Finall...
