网络安全防范体系及设计原理分析

Network Security System Snalysis and Design Principles

今日的世界已进入了网络信息高速流通的时代,它仿佛使地球变小了,把世界各地的距离拉近了。随着计算机技术的发展,网络进入了千家万户。中国的网民每年以百分之两位数字递增,已成为世界上上网人数最多的国家。它快速地改变了我们的生活和工作方式,也在改变着我们的思维方式,给大家带来很大的方便。但同时基于网络的安全问题也日益突出。不论是外部网还是内部网的网络都会遇到安全问题的挑战。这主要包括两个方面:一是管理问题,二是技术问题。本文首先概括了网络信息安全的概念和当前网络安全解决方案的局限性,然后对网络安全防范体系及设计原理进行了系统分析。

the world today has entered the era of network information high-speed circulation,as if it makes the earth becomes the world＇s close.With the development of computer technology,network has entered innumberable families.China＇s Internet users every year by two percent digital increases.Internet has become the world＇s largest.It rapidly changed our life and work methods and is also changing the way we think,bring you great convenience.But at the same time based on network security is increasingly prominent.Either internal or external network of network will meet safety issues,challenges.It mainly includes two aspects：one is the management problems,second is the technical problems.This paper generalizes the network information security concepts and current network security solutions of limitations,and then to network security system and the design principle of system analysis.
