【摘要】 重点讨论了基于状态检测防火墙系统的模型。通过对包过滤机制加入状态检测模块,将状态信息的保留机制与过滤机制结合起来,应用状态迁移分析技术设计状态检测模块,使系统对IP包的转发效率有了较大的提高,并且对于包过滤模型中存在的先天性安全漏洞做了较为完善的弥补。更多还原

【Abstract】 This paper introduces the model of state inspection firewall system. The filter mechanism of state information is combined with its reserved mechanism by adding state inspection module to the package filter mechanism. By designing state detection module with State Transition Analysis Technique, the transmitting efficiency of system to IP package is improved.It is also a relative complete supplement to the security leak existed in the package filter model.更多还原
