Network Attack-defense Situation Awareness Based on Dynamic Game with Incomplete Information

To reflect network attack-defense confrontation situation and solve the problem of strategy dependence,an incomplete information dynamic attack-defense game model is proposed.It constructs network attack-defense confrontation model,and based on the definition of attack and defense actions’ sequence,the method of conversion from attack-defense confrontation model into extensive form game model is presented,then equilibrium strategy solution can be acquired.
