毕业设计精品]计算机网络技术及其在校园网的研究与应用毕业论文.pdf

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.

ABSTRACT
ABSTRACT
In this paper, a variety work security threats faced by the system to
introduce work security technology. And for the safety of the work to study,
first of all an analysis of the safety of colleges and universities work and then build
a security defense system and strengthen the security management of both the design of the
work security policy. The research paper, I first learned about the major issues of
network security threats and take advantage work security knowledge to analyze the
security issues. Secondly, through work technology, e to work is
faced with security threats. Finally, P2DR model established with the idea to create a campus
network security defense system.. e to build an work security defense
system to address major threats to the work and the hidden ways and measures
necessary.
