基于子网过滤结构的各种防火墙体系的安全性分析

Analysis on Security of Each Firewall Architecture Based on Subnet Filtering Architecture

介绍了子网过滤结构的防火墙及其各组件的功能,在此结构基础上引申出一系列变化了的结构体系并对这些体系结构的优缺点作了分析,最后从防火墙的应用成本、高效灵活和安全保障等方面对各体系结构进行了综合评价。

The principle of subnet filtering Architecture and the functions of its components are introduced.Some architectures are induced from it and the virtues and the defects of them are analyzed.Finally,cost,efficiency and security synthetically are evaluated.
