Research And Design Of Campus Network Security

Along with theses recent years Universities Information construction development , Various universities' campus network has obtained the Huge development opportunity , Various universities obtained abundance of"West universities campus network project of basic construction","Japanese Yen loan project","The central committee and place altogether construct the laboratory project"And so on special financial support .These financial supports enable our various universities campus network infrastructure obtain the chance of renewal, also enables our campus network's scale to expand and to cover the entire campus. The campus network technology obtained the promotion, unceasingly deploys of each kind of campus network application system. Through and so on scientific research demand, teaching application, on-line work, on-line entertainment, the network application gradually influence every aspects of the campus life.The on-line work, prepares a lesson on-line, the on-line teaching, the on-line search, the on-line studies, to receive email, on-line chats, on-line game and entertainment, shopping on-line, the campus user's on-line time is more and more . In 2005 Ministry of Education science and technology development center announced correlation data shown that 98.4% universities teaching, scientific research and the administrative work already has completely united into the campus network. There's 90.5% universities' classrooms and 74.35% universities' students dormitory have access point of network. Today the campus network nearly has covered all quoin of each University campus.While our each person's life more and more close to the campus network application, the importance of campus network security and stable were came out. We must construct the more and more campuses network application, Opening to more and more users is contradictory with the campus network security and stable. This article is precisely based on such pair of contradictory and studied the campus network security policies. The main content of this article is as follows:①Studies the current situation of campus network construction, campus network technology, construction pattern, campus network model application, campus network daily management.②Studies the threat which the current network campus network faces, as well as these threats and attack classification, also has analyzed the TCP/IP protocols some born that way shortages of security.③Has studied the current network security technology, Including: Firewall technology, IDS, IPS, VLAN, differences between strategy routing and routing policy and it's application in network security. AAA technology, network security, encryption technology and so on.④I have studied how to formulate the campus network security policies, and take the network of SISU as the test environment to establishment and implements this strategies based on this campus network environment.This topic research enabled us to find the method to formulated the campus network security policy, and this strategy design and the implementation means also apply to the enterprise network environment which has the same technical structure, it will play importantly role to enhancement network security, improve the network user's safe consciousness, standard network behavior.
