The Research Of IP Network Security System Of GuiZhou

At the arrivals of information age, government surf the net, online the flourishing developments of businesses of surfing the Net, family surf the Net by enterprise etc. The network application is permeating each link that we work and living rapidly. The security of the network, including the function that information datum security and network equipment serve at the network is safe, Become" great anything" of close concern to each other of interests with the country, government, enterprise, individual day by day. IP network is becoming the carrier for various information services. However, due to IP network's open system, the security of network becomes increasingly serious and complicated. How to establish the IP network security system under new circumstance is an important problem in nowadays' network operation and maintenance.GuiZhou telecom IP network was established in 1997. Through these years' construction and development, it has been a wideband network covering the whole province, and on which, lager numbers of equipment with different size produced by different company is running. Now, the network can provide multi-ways accessing to Internet, such as dialing, ADSL, VDSL, FTTX+LAN, etc. as well as multi network application service, such as Web, Mail, Charging, IDC service, etc. The total Internet subscribers have been over 300,000.At present, treatments at network security problem only some network security strengthen telecommunications of Kweichow IP network and network security the arrangements of products, Lack a piece of whole tactics of network security, can't give play to the utility of the products of network security the best . " wooden barrel effect" exists in the question of network security, any some loophole may cause the collapse of the whole network . So, need a set of feasible network security tactics urgently and carry on network analysis to IP's network of telecommunications of Kweichow, Make out the system of network security and implement.After analyzing the GuiZhou telecom IP network, by applying advanced modem dynamic network security theory on the angle of technique, this article, from all aspects, designs the network security technical system for the Guizhou IP network. And this system will be implemented combining with the project.This article mainly does the work as following:1 Establishing the network security demand and security object for Guizhou telecom IP network.2.Introducing and analyzing the modern dynamic network security theory. 3 Introducing the key techniques of network security and its development. 4 Designing the security technical system for Guizhou telecom EP network. 5 Implementing and assessing the Guizhou telecom IP network security project.
