随着
计算机的飞速发展以及网络技术的普遍应用,随着信息时代的来临,信息作为一种重要的资源正得到了人们的重视与应用。因特网是一个发展非常活跃的领域,可能会受到黑客的非法攻击,所以在任何情况下,对于各种事故,无意或有意的破坏,保护数据及其传送、处理都是非常必要的。计划如何保护你的局域网免受因特网攻击带来的危害时,首先要考虑的是防火墙。防火墙的核心思想是在不安全的网际网环境中构造一个相对安全的子网环境。本文介绍了防火墙技术的基本概念和系统结构,讨论了实现防火墙的两种技术手段:一种是基于分组过滤技术(Packet filtering),它的代表是在筛选路由器上实现的防火墙功能;一种是基于代理技术(Proxy),它的代表是在筛选路由器上实现的防火墙功能.

Abstract:
Along with the fast computer development and the universal application of the network technology, along with information times coming up on, Information is attracting the world’s attention and employed as a kind of important resources. Internet is a very actively developed field. Because it may be illegally attacked by hackers, It is very necessary for data’s protection, delivery and protection against various accidents, intentional or want destroy under any condition. Firewall is the first consideration when plan how to protect your local area network against endangers brought by Internet attack. The core content of firewall technology is to construct a relatively safe environment of subnet in the not-so-safe network environment. This paper introduces the basic conception and system structure of fire-wall technology and also discusses two main technology means to realize fire-wall: One is based on packet filtering, which is to realize fire-wall function through Screening Router; and the other is Proxy and the typical representation is the gateway on application level.

作者点评:随着INTERNET在我国的迅速发展,防火墙技术引起了各方面的广泛关注。一方面在对国外信息安全和防火墙技术的发展进行跟踪、另一方面也已经自行开展了一些研究工作。目前使用较多的,是在路由器上采用分组过滤技术提供安全保证,对其他方面的技术尚缺乏深入了解。防火墙技术还处在一个发展阶段,仍有许多
问题有待解决。因此,密切关注防火墙的最新发展,对推动INTERNET在我国的健康发展有着重要的意义。
