Campus Network Security System Design And Implementation

With the rapid development of Internet technologies, university campus network has become the most important means to support university teaching, research and reform, but the security situation in the campus network directly affect teaching in schools, therefore, study the campus network security Construction of the system has a strong practical significance.This papers based on the hunan normal university campus network security detail investigation and analysis. the construction of the campus network security system design ideas, through the reliability of the network system construction, the server system security improvements, remote access system building, construction of anti-virus system and multi-link building, give a comprehensive description of the construction of the campus network security system.paper presented for the network security settlement system of Hunan Normal University,, according to the different demands,the network will be divided into various sectors of the school to a different VLAN, not only enhanced manageability, improved security, but also to reduce the broadcast domain, improve network performance and efficiency, will be limited to a computer failure in a specific VLAN, and will not extend to the entire network. At the same time the prevention of priority sectors to achieve the static and dynamic combination of active and passive combination, enhanced their security. Construction of the campus security systems, this article mainly from hot standby routing technology to achieve the reliability of the network, Dual Hot-backup, RAID, as well as link bundling techniques to achieve the security of server systems, combined with project management experience, completed the development of Hunan Normal University campus network security system.This papers not only strengthens the external network attacks, and in particular on the internal network to enhance the prevention and management. Prove that this program can reduce the use of computer viruses, harm to the network; reduce network impact of an intruder on the campus network; greatly reducing the adverse information in the Campus Network of the dissemination of information; improve access security; to ensure the school's Web applications. Achieved through the implementation of the system inside and outside the integration, focusing on prevention within the overall goal.
