The Campus Network Network Security Policy Model Applications

With the extensive application of computer network technology and Digital Campus, with the scale of campus network enlarging and increasing application of network, campus network security management becomes more complex, which requires highly-professional network manager. In the mean time, network security incidents have occurred frequently, the virus rapidly spreads, and the speed of network managers'response to these incidents is far below the rate of abnormal events. Therefore campus network security management and stable operation has become one of the problems which attract most attentions in the field of computer network.Thesis is based on the project of"Digital Campus Network of Zibo Vocational Institute"on studying the campus network management, thesis designs a scheme which simplifies network management and enhances network security and availability in order to improve the despondence speed of incidents, and ensure campus network availability and controllability according to fast deploying relevant security policy.In research area of network security, policy management has been a hotspot all the while. Policy management reckons on bringing forward a strong network management solution to manage the whole network resources. thesis analyses and compares two architectures of policy management, IETF and TMF policy continuum, combined with practical requirements of campus network, thesis introduces a Policy network management model for the campus network, which combines strongpoint of two kinds of structures.On this basis, thesis deeply researches the detection of policy conflict and policy deployed automatic technologies, and brings forward the detection of policy conflict which uses ultra dimensional space algorithm and network equipment-independent security policy automatic distribution technology. At last, thesis design a related prototype system, this system can enhances campus network security performance and ensures campus network availability.
