The Design And Application Of AnShun Electronic Government Network Security

The essential target of constructing an electronic government network is to establish an open and unified network platform based on the standard. It can help different departments of government exchange information and share resources in this platform, simultaneously guarantee the independence and security of various departments information.Firstly, the article analyses Anshun's the network security issues of E-government and the technical aspects of the characteristics of MPLS MPLS/VPN, which also proposes the construction of VPN by using MPLS settling the security problems of Chief network. It expounds the achievement of VPN work process by using the MPLS and the advantages of the MPLS' net characteristics in detail, which at the same time researches the PKI system and discusses the aspects of function, construction and organization.Secondly, the article designs the e-government's network security solutions based on the MPLS / VPN of Anshun City, and layouts some aspects of MPLS / VPN network in several main areas: IGP agreement, BGP protocol, routing reflection of VPN and network structure. On the basis of the program, it offers a security of information systems based on PKI / CA and VPN and argues the function, construction and composition in detail, and then it designs and achieves the goal of implement security of Anshun's e-government network. This project uses the strong and broad transmission capacity of common backbone network, reducing the costs of internal network construction and greatly improving the users' network of management and the operators' flexibility, which at the same time meets the needs of users' security of information transmission, real-time, broadband, and convenience. The program is characterized by low-cost and security. In accordance with the program, it deploys and applies the part of Anshun' e-government network security system. After testing experimentally and application, the results shows that the Anshun's e-government network has a better ease of using and network security.
