【摘要】：高职高专院校信息化建设不断深化,校园网建设规模也在不断扩大,学院教学以及行政事务对校园网的稳定性和可靠性要求不断提高。在校园网应用及负载不断增大的环境下,凸显出众多的网络安全问题,常见的问题为校园网主站被篡改,IP地址被盗用,内网病毒泛滥等。本文研究内容是分析及评估唐山职业技术学院智慧校园与虚拟化项目中的园区内部网络的软件与硬件成熟度模型的级别,根据不同的安全需求设计相对应的安全系统,并进行建设上线,针对学院的信息化建设中存在的安全问题与建设需求测试其安全系统性能。本文是针对高职高专学校校园网的安全系统建设,其研究意义可以对相应学校的类似系统起到借鉴作用。论文首先阐述了高职院校计算机网络安全的研究背景、高职院校计算机网络的安全现状以及高职院校校园网络安全研究的重点、难点;回顾了高校中网络的发展与网络应用以及高职院校校园网建设的状况和常用的网络安全技术,为分析高职院校网络安全问题提供了理论基础【1-2】。其次,浅析国内高职院校网络安全建设中的具体问题,例如在硬件、软件兼容、网络管理员及用户等方面。再次,依据校园网络安全的理论知识结合唐山职业技术学院校园网络安全工作实际,总结近些年来对校园网络管理的心得和体会,借鉴国内外成功案例和先进经验,以唐山职业技术学院校园网络现有设备和资源为基础,重点从硬件与软件、管理制度与监控机制上提出一套解决校园网络安全问题的系统。本文通过对唐山职业技术学院校园网络的大量研究,认清了校内网建设中存在的各种安全问题和其相对不稳定性,进一步明确了今后学院信息化建设的安全性能是何其重要。在反复参考同类院校的建设经验的基础上,本文给出了适合唐山职业技术学院园区内网的跨校区综合设计方案,并在唐山职业技术学院的三个校区得到了推广与应用。网络安全的基础是网络分层中接入层、汇聚路由层、核心交换层的多层安全,本文着重在网络安全上详细综述了以上三种安全,对学生的学习和学院的建设起到了积极推动作用。
[Abstract]:The information construction of higher vocational colleges is deepening, the scale of campus network construction is also expanding, and the requirements for the stability and reliability of the campus network are constantly improved for college teaching and administrative affairs. In the environment of campus network application and increasing load, many network security problems are highlighted. The common problems are that the main station of campus network is tampered with, the IP address is embezzled, the intranet virus is flooding and so on. The content of this paper is to analyze and evaluate the level of software and hardware maturity model of campus inner network in the intelligent campus and virtualization project of Tangshan Vocational and Technical College, and to design corresponding security system according to different security requirements. The security system performance is tested according to the security problems and construction requirements in the information construction of the college. This paper is aimed at the construction of security system in the campus network of higher vocational schools, and its research significance can be used for reference to the similar systems of the corresponding schools. Firstly, the paper expounds the research background of computer network security in higher vocational colleges, the present situation of computer network security in higher vocational colleges and the emphasis and difficulty of the research on campus network security in higher vocational colleges. This paper reviews the development and application of network in colleges and universities, the status of campus network construction in higher vocational colleges and the common network security technologies, which provides a theoretical basis for analyzing network security problems in higher vocational colleges [1-2]. Secondly, it analyzes the specific problems in the construction of network security in higher vocational colleges in China, such as hardware, software compatibility, network administrators and users and so on. Thirdly, according to the theoretical knowledge of campus network security combined with the practical work of Tangshan Vocational and Technical College campus network security, summed up the recent years of campus network management experience and learn from domestic and foreign successful cases and advanced experience. Based on the existing equipment and resources of campus network in Tangshan Vocational and Technical College, this paper puts forward a set of system to solve the security problems of campus network from the aspects of hardware and software, management system and monitoring mechanism. Through a lot of research on the campus network of Tangshan Vocational and Technical College, this paper recognizes the various security problems and relative instability in the construction of the inner network, and further clarifies how important the security performance of the information construction of the college is in the future. On the basis of repeatedly referring to the construction experience of the similar colleges, this paper presents a comprehensive design scheme for the inter-campus of Tangshan Vocational and Technical College, which is suitable for the inner network of the campus of Tangshan Vocational and Technical College, and has been popularized and applied in the three campuses of Tangshan Vocational and Technical College. The foundation of network security is the security of access layer, convergent routing layer and core switch layer in network layer. To the student's study and the college construction has played the positive promotion function.
