1、 I 摘 要 本文从计算机网络面临的各种安全威胁，系统地介绍网络安全技术。并针对校园网 络的安全问题进行研究，首先分析了高校网络系统安全的隐患，然后从构建安全防御体 系和加强安全管理两方面设计了校园网络的安全策略。本次论文研究中，我首先了解了 网络安全问题的主要威胁因素，并利用网络安全知识对安全问题进行剖析。其次，通过 对网络技术的研究，得出校园网也会面临着安全上的威胁。最后，确立了用 P2DR 模型 的思想来建立校园网的安全防御体系。并得出了构建一套有效的网络安全防御体系是解 决校园网主要威胁和隐患的必要途径和措施. 关键词关键词: : 网络安全，安全防范，校园网 ABSTRACT II A
2、BSTRACT In this paper, a variety of computer network security threats faced by the system to introduce the network security technology. And for the safety of the campus network to study, first of all an analysis of the safety of colleges and universities hidden network and then build a security defe
3、nse system and strengthen the security management of both the design of the campus network security policy. The research paper, I first learned about the major issues of network security threats and take advantage of network security knowledge to analyze the security issues. Secondly, through the ne
4、twork technology, will come to campus network is faced with security threats. Finally, P2DR model established with the idea to create a campus network security defense system And come to build an effective network security defense system to address major threats to the campus network and the hidden ways and measures necessary. Key words: Network Security, Safety Precautions, Campus Network 目 录 第 1 章 前言 1 1.1 网络安全发展历史与现状分析 1 1.1.1 因特网的发展及其安全问题 1 1.1.2 我国网络安全现状及发展趋势 3 1.2 校园网存在的安全问题 3 1.3 论文的主要任务
