Study Of Campus Network Security Management And Architecture Optimization

With the rapid development of Internet technology,campus network(CN)has become an important support means for teaching,scientific research,management,logistics and other work in higher education institutes.Whether it can operate in a stable and safe environment directly or not,it truly affects the orderly and stable development of the various businesses in the colleges.Therefore,it is of great practical significance to study the construction of security system of campus network.The goal of this paper is to design a high availability,advanced technology,stable and safe management and architecture of campus network.The main research contents are divided into three aspects:First,on the basis of the sufficient research and the the author's experiences,the paper designs a set of security management and architecture of campus network.It consists of three parts: infrastructure security system of campus network,security mechanism of campus network,analysis and prevention system of application of campus network.In the infrastructure security system of campus network,the focus is on the Internet exit area,Intranet area,server and system area.After a series of experiments,the topology diagram is drawn to show the research results.In the security mechanism of campus network,the establishment of various management systems,the management of Internet users and the implementation of emergency plans are mainly studied.In the analysis and prevention system of application of campus network,the current situation analysis and prevention measures of campus network in higher education institutes are mainly studied.Through the study of this chapter,a comprehensive architecture of security system of campus network shall be summarized.Second,According to the experiences of actual situation of the college and the findings from the above,the idea of design and the goal of next construction in security architecture of campus network of SCCT are proposed.Through the analysis of the actual situation of the college,the existing problems are summarized.In the basic network,the security design concept of network exit area is proposed,and the existing problems are solved by means of multiple exits,backup lines,deployment of security control equipment,etc.The internal area of campus network is built with layered model structure.The Key devices,such as “convergence and access switches”,are designed by applying VLAN partitioning,ACL strategy,redundant links,link aggregation and other technologies.In the server area,the focus is on protecting the various business systems hosted.By setting up server gateway,unified identity authentication,cloud security management platform and other security facilities,the server security can be ensured.In terms of system construction,the existing rules and regulations of campus network management are improved on the basis of investigation,interview and consultation.At last,the security system of campus network in SCCT is constructed.Thirdly,according to the system and architecture designed,and the actual application in SCCT,the paper focuses on the network exit area and server area to conduct various attack and defense tests,which achieved good prevention effects.
