| With the popularization of Internet,most colleges and universities have set up their own campus network.The use of campus network can make full use of resources,improve work efficiency and speed of information processing. However, with the increase of the hacker intrusion, and the overflow of network virus, the security of the campus network is more and more serious challenges. Therefore, how to adopt different security measures, to improve the campus network security and stability, has become one of important topics to be studied.At present, most of the campus network security plan priorities have one-sided sex, the security in the process of safety technology and management measures are often relatively simple. Such as the simple adding hardware firewall or lack of security measures for VLAN (virtual local area network) technology. Therefore, the campus network still has higher security vulnerabilities. To solve the safety problem of the campus network, to construct a security measures to improve the campus network need to consider using a variety of different ways, to effectively prevent from external network environment existed in different variations, and can reduce the loss to the minimum.This article through to the present different campus network in construction process in the presence of safety comprehensive evaluation, combined with the characteristics of campus network system on campus network in architecture, could face security risks to make comprehensive and detailed study. After that, this paper will present the domestic mainstream network security technology research, through a comprehensive comparison, on which fit our school campus network security technology are introduced, so as to build a set of perfect, level of the campus network security system.Considering the current Wulanchabu city medium occupation technical school there is not a perfect system, the campus network, campus network exists but largely convenient for students of teachers and students to work and study. Therefore, the starting point of this article is to build campus network in our school. While in the erection process of our campus network may have problems, as well as how to improve network security, stability and convenience of considering. First consider from macroscopical on my campus network partition, so that when a regional problems, not on the periphery of the network environmental impact; secondly, consider the Internet user base, will be targeted to limit certain specific application usage, to save bandwidth, improve the network quality; third at present, the common security threats and network attack undertakes an analysis, put forward the corresponding measures to guard against such threats, the campus network user violations, lest cause irreparable damage.Finally, to recognize the different network security measures will be introduced, can greatly enhance the network security, and multi-level, subregional network management protocols, can effectively improve the quality of network service. Thus for the campus network layout provides for a secure application platform. |
