| With the popularization and development of the Internet, Various financial and commercial activities are frequently carried out on the Internet, Internet/Intranet technology has been widely used in every field of society, not only bring convenient to people's lives, but also make people's lives more colorful. At the same time, with the rapid development of network technology, education information and campus digital have become the direction of the education. The campus network plays an more important role in many areas, just like teaching, scientific research, management and foreign exchange, and become more and more important. All schools to seize the opportunity to set up their own campus network, with the expansion of the campus network and the amount of users, the security of campus network and data resources are also becoming more and more seriously, the benefits of the schools are damaged seriously. So, under now available condition, how to improve the campus network security, ensure the operation of campus network stable and highly efficient, become an important subject which the article deals with.Security of network is a complicated system, related to many factors, like the system software, hardware, environment, users and so on. The article based on the object of ZB normal college, discussed that the use of a variety of network security technology in solving the campus network security, and put forward specific safeguard the campus network security solutions. This thesis main content as follows: Firstly, the thesis discusses the computer network security situation and the research background, and construction and development of ZB normal college campus network and the major threats. Introduces the network security techniques include of firewall techniques, techniques in anti-virus, cipher techniques, identity identification, visiting-control techniques, safe scanning techniques, data copy and data restoration techniques and VPN techniques and so on. At the same time, briefly introduces the development trend of network security technology. And based on this, the paper explored the application of network security techniques on campus. Obtains the related campus network security through the consult pertinent data of the theory knowledge and the first material, as a network management administrator for several years, the author also shared his own work experiences with us on how to use the network security strategies. Then by referring to the experiences of other schools and on the basis of the present positions as a network administrator, the author mainly explored how to synthesize various network security technologies to solve the campus network security problem, and proposed a method that some students download films unlimited in multimedia classroom with the technology of ACL based on time.Except that, the paper also discussed the non-area of technology like policy, environment in the campus network of safe constructional application. At last, the paper made a summary and outlook to the applications in solving campus network security with the security technologies of network. |
