防火墙在网络中的应用与研究

防火墙作为应用最广泛的网络安全产品,其安全性测试起步较晚,已远落后于防火墙技术的发展。文章首先介绍了网络的基本组成原理及其优缺点,同时介绍了防火墙的主要技术类型,并详细描述了包过滤型防火墙的工作原理,提出了防火墙设备的安全性测试要求,在此基础上讲述了防火墙设备安全性测试的方法和测试的主要项目,以及从深入剖析网络攻击软件的原理出发,设计出了防火墙在实际应用中的安全策略。

Research and Application of Firewall In Network

Firewall is the most widely used network security product,while its security test starts late,which falls far behind its technology development.The article first introduces the basic network architecture and its advantages and disadvantages,as well as the main technical types of firewall,then describes in detail the packet filtering firewall-work principle,proposes the security test requirement of firewall equipment,and based on which describes the method and main items of firewall equipment security test,a...
