Designing Scheme Of Campus Network Security For Changqing School

With the rapid development of Internet, various universities are promoting the construction of digital campus actively, the campus network (CN) scale is stretched gradually, and campus network users came in increasing numbers, the application of campus network is increasingly perfect, thus the campus network security issues are more and more prominent.Seeming Changqing School as the background, this paper starting from the present situation of its campus network, analyzes the campus network security requirement, and finally proposes the solutions of network security for Changqing School. The solution is divided into three parts:Network boundary-protection, Access control, and inside control.On Network boundary protection, we use firewall and IDS, Build a more comprehensive border protection measures. And the paper focus on the firewall rule matching algorithm, discuss the optimization measures of BSLT.In the access control strategy, we use Identity authentication system based on802.1x Protocol, and give the solutions for the security problem of802.1x Protocol.For the internal control of campus network, We manage or control of Intranet by dividing VLAN and Loading antivirus system. And focusing on server area we deploy firewall, strengthen the security of server area.Through the security deployment of these three aspects, we build a complete security solution for the campus network of Changqing School. For the protection of the safety of campus network, it Has a significant role.
