The Research And Application Of Campus Network Security Access

Network security access technology is a hot field of network security. With the development of the Internet, people are dependent on the network increased gradually. Firewall, VPN and other technologies and other traditional network security technology, security concerns are outside the network. But with the rapid development of the local area network and technology, the network has become the weak link in network security, network security access technology has gradually attracted people’s attention.The main contents of this network within the campus network security access technology. Campus network has a large number of users, groups, complex, and high stability requirements. Should the mismanagement, it will lead to security risks from the internal network more and more. In this thesis, the actual construction of the campus network as the background, to the campus network security access technology research and application.MAC address filtering and binding, PPPo E dial-up, 802.1x technology, a Web-based Portal authentication and other common network security access technologies are analyzed and compared to study the basic working process of these security access technology, use of the environment, and their advantages and disadvantages are analyzed. To solve the problem of secure access to the campus network, the formation of a promotion, easy to implement network access solutions.The thesis from the global to local needs analysis, from the local to the whole design integration. Taking a vocational school campus network, for example, the demand for the campus network of different user groups, sub-module access program designed different security zone. In addition, the thesis model was practical research program, making secure access to various parts of the application program, and the core configuration analysis and comments. Finally, the effect of the implementation of security access solutions were tested, objective record of the test results. Through research and practical application, the formation may promote the use of campus network security access program. The test results show that the points herein design can solve most needs secure access to the campus network, to enhance the safety of the campus network has a certain effect.
