摘 要 随着计算机技术和通讯技术的飞速发展，网络正逐步改变着人们的工作方式和生活方式，成为当今社会发展的一个主题。网络的开放性，互连性，共享性程度的扩大，特别是Internet的出现，使网络的重要性和对社会的影响也越来越大。随着网络上电子商务，电子现金，数字货币，网络国税等新兴业务的兴起，网络安全问题变得越来越重要。 网络越来越深入到人们的生活和工作当中计算机安全变得越来越重要了尤其是用于商业目的计算机，本文介绍一些关于计算机安全的基础知识，对于网络安全内容，从技术角度，服务已经技术支持方面介绍了网络安全的方法。并且详细介绍了网络防御的解决方案，从物理安全、防火墙技术、VPN技术、网络加密技术、身份认证、多层次多级别的防病毒系统、入侵检测技术、虚拟专用网技术等多方面介绍了网络安全防御的技术，从而大大降低了网络安全性，大大降低了病毒的入侵、木马的入侵、黑客的入侵可能性。 关键词：网络 安全 攻击 病毒 Abstract Along with the computer technology and the communicationtechnology rapid development, the network gradually is changingpeoples work way and the life style, becomes a subject which now thesociety develops. Network openness, interlocks the nature, the sharingdegree expansion, specially the Internet appearance, causes thenetwork the importance and the influence more and more is also big tothe society. Along with the network in the electronic commerce, theelectronic cash, the digital currency, the network and so onemerging service starting, the network security question changes moreand more importantly. The network more and more penetrated to peoples life and the work thecomputer security changes more and more importantly has used inparticular the business objective computer, this article introducedsome about the computer security elementary knowledge, regarding thenetwork security content, from the technical angle, the servicealready the technical support aspect introduced the network securitymethod. And in detail introduced the network defense solution, fromthe physical security, the firewall technology, the VPN technology,the network encryption technology, the status authentication, themulti-level multistage other anti-virus system, the invasionexamination technology, the hypothesized special-purpose nettechnology and so on variously introduced the network security defensetechnology, thus greatly reduced the network security, greatly reducedviruss invasion, the wooden horse invasion, hackers invasionpossibility.
