| With the popularity of the network technology and the development of the network in various university.Most of them have setup their own campus network,which has become an important part of the information system, also to be measure a college is one of the important factors core competitiveness .Just as the internet,there are various security problems existed in campus network.In the early stage,because of security awareness , seeurity management and other aspects.Network security was not paid suffieient attention,which caused network security incidents continue to occur, and made the campus network security at great risk.With the advancing and promotion of digital campuse on struction, how to build a reliable campus network security system has become a significant problem.This dissertation using the method of theory with practice, Shanghai sanda college campus network as an example, the present situation and management of campus network has made the detailed analysis, combining network management experience, introduce base on IPV6 intrusion detection, based on SNMP protocol and the network traffic monitoring system, hope to help university digital campus setup some experience and reference accumulated.The first part of this dissertation mainly expressed the background and significance of the purpose and the main content. The second part intrduced the situation of Shanghai Sanda university campus network, analysis and design the network security demand.The third part According to the sanda university campus network security system made technical scheme and implementation of the design plan.The fourth part is important, Network security system for the overall description, and designed three experiments,base on IPV4\IPV6 environment of intrusion detection, flow real-time monitoring,use vrrp protocol realize the backup of network device.The fifth part is to generalize summary, from the campus of the national education digital future informatization construction. |
