Network service states were regarded as basic situational elements, network offense and defense behaviors were both taken into account, gambling model for network security situation was constructed, in which the model parameters such as state space, strategy set and payoff function were definitely formulated. By simulation experiment, the Nash equilibriums was computed when attackers and defenders got a balance between payoffs, then quantitative depict of network security situation was accomplished.
