The Design Of Campus Intranet Access And Security System

With development of computer technology in recent years, the scale of network is becoming more and more greater, the user number is also increasing rapidly. It makes the network safe problem become an important topic of computer science. The internet user number increases rapidly each year in our country. China has become the one of most internet user in the world. Most of university have build up their own intranet, which had became a very good tool for teacher and students. However, with the devolopment of network and increasing of the user, the network security has become an important problem. There is a lot of cases of the attack of hacker and computer virus around world. To prevent such case from happening, the security of campus intranet has to be well developed and maintained.In this paper, using trust calculation theory, the security access system model based on trusted connection is presented and the security and stability of campus intranet is studied.According to the characteristics of campus intranet, we us current network security technology to build up the secure access solution for information sensitive department on campus intranet based on TNC and the verification management system which includes verification, authorization, logging based on AAA protocol.Based on structure of worm virus, we design self-protection system on campus intranet.As the BT download is very common in campus intranet and often affects the network speed, the principle of BT software is analyzed and the speed control method for BT download is designed in this paper.
