摘要
为了克服传统防火墙的局限性,分布式防火墙的概念应运而生。在分布式防火墙中,安全策略统一制定,由各主机负责实施,很好地解决了边界防火墙安全策略越来越膨胀的弊端及内部网的安全性问题。论文对分布式防火墙的本质特征,体系结构和运做过程进行了详细的阐述。
This paper analyses the inner network is reliable,is proved to be connectless in fact.Concept of distributed firewall is intrduced to eliminate these shortcoming.The distributed firewall takes on the architecture that the Control Center makes security policy and many node firewalls execute the policy,and effcetively solves the abuse raesed with the more and more policy and the inner network＇s security.Then the basic principle and related concept of DFW are described and a close study is made about the system models of DFW.
