Campus Network Security Engineering Practice And Research

With the popularization of internet and the development of domestic universities network construction, the campus network has been mostly established, which nowadays has became the important component of university information. However, with the increase of hacker's invasion and the overflow of network virus, the security of campus network" has become the intractable question. Therefore, it is" urgent to maintain the system's security in the opening network. The construction of network security system is a quite significant subject which involves various aspects: from hardware to software, from PC to network. This thesis systematically introduces the concept of network security, discusses various threats to security of campus network, analyzes network system security, and proposes the architecture and solution of network system security according to its construction targets. This thesis also conducts the research to the campus network security solution, such as physical security, access control, viral protection, security management. According to the existing network equipment, we apply the VLAN technology, the NAT technology, the access control lists of a router, and the PPPOE digit dialing method to realize the safety protection on campus network of Jinggangshan College.We had implemented the solution in campus network of Jinggangshan College. The result shows that the solution is well-designed and can satisfy requirements of campus network security.
