An improved model of distributed network information security

According to network security problems, a new more initiative distributed network of safety warning model P2DWR2 is developed in this paper, based on the available P2DR model. The key technologies of P2DWR2 model, i.e. deployment of security policy, cooperation of security components etc., were discussed. The new model compensates the insufficiencies of P2DR model, such as low automatic level and requirement of human involvement to complete the security incident response deficiencies. P2DWR2 model provides the policy uniform defines, automatic distribution, self-adaptive management functions and so on. And it makes the core effect of security policy realized.
