Analysis And Research On Campus Network Security Evaluation

With the development of CERNET and unceasing expansion of the network demand for university teachers and students, all colleges and universities have marched into a building boom of campus informatization——Campus network infrastructure has been updated, the network has covered the entire campus, and campus has unceasingly built a variety of campus network applications, such as educational management systems, office automation systems and so on. The campus network not only play a role for delivering platform of teaching, research, management and service, but also meet staff and students'demands for online office, online preparation, online teaching, online search, e-mail, Web chat, online entertainment, online shopping, The network application already gradually seeped to all aspects of the campus life. The closer we contact with campus network, the more apparent the importance of the campus network security will become.This thesis aims at constructing a set of campus network security evaluation system which is complete, scientific and suitable for the university , by the analysis and study of the campus network evaluation to determine the level of the campus network security, help college accurately understand the status of the campus network security, and provide an important basis for improving the overall level of the campus network security, drawing up scientific campus network security plan and the reasonable campus network security tactics. Meanwhile it has the important theory significance to further enrich the theory of network security evaluation system, and establish the scientific and standard evaluation models and standards.The thesis is divided into five chapters:Chapter1, Introduction. This chapter discusses the issue of background and significance of the study, reviews the currently domestic and overseas situation of research, and makes major research and innovation;Chapter2, Overview of relevant theories of network security evaluation. This chapter mainly has carried on the comprehensive summary on the research present situation from two aspects of network security evaluation——the evaluation criteria and the evaluation method, has carried on the induction and the summary of the current network security evaluation method;Chapter3, Construction of evaluation index system for campus network security. This chapter mainly uses DEMATEL method to optimize network security evaluation index system, so as to arrive on campus network security evaluation index system;Chapter4, Study of campus network security evaluation. Firstly, this chapter determines index weights by combining entropy weight method and AHP method, and then construct the campus network security evaluation by second-level fuzzy comprehensive evaluation method;Chapter5, Example analysis of campus network security evaluation model. This chapter takes Shanxi Traffic Vocational and Technical College as an example, carries on the campus network security evaluation by the model which the fourth chapter proposed, gives this campus network security level, and proposes some targeted campus network security tactics.
