The Campus Network Security Design And Implementation

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,to speed up information processing, make full use of high-quality resources to enhance the efficiency and the sharing of resources have played an invaluable role. 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's 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 article has made the summary to network security's correlation theories and the major technique, and take Chongqing College of Electronic Engineering campus net's security system as the example, has analyzed the security risk which in the campus network exists, proposed the campus network security system's design proposal and the concrete implementation plan, have carried on the summary finally to the campus network security technology.This article mainly has conducted the research and the discussion from following several aspects to the campus network security:1.researched and the discussioned the safety of domestic and international status of the campus network;2. introduced the present main network security technology;3. in view of the current campus network of Chongqing College of Electronic Engineering, from the physical level, the link level, the network level, the systematic level, the application layer and management layer has analyzed the security risk which separately in the campus network safety system;4. elaborated the campus network security requirements of Chongqing College of Electronic Engineering;5. in view of the Chongqing College of Electronic Engineering campus network security requirements, separately from the physical level, the network level, the systematic level, the application layer and the management has carried on the design to the campus network security system; 6.proposed network system's safe guard system and the concrete solution. The plan from the physical layer security, network layer security, system level security, application-level security and security management classified research, combined with the Chongqing College of Electronic Engineering of the actual situation in the campus network, according to the existing network equipment, we apply the VLAN technology , the access control lists, the user authentication, the flow control, the data backup and recovery and the security of management to achieve the basic security protection of campus network that the use of.7. summary and to the following work forecast.We had implemented the solution in campus network of the ChonQqing College of Electronic Engineering. The result shows that the solution is well-designed and can satisfy requirements of campus network security.
