Sichuan Postal Network Network Security System Design

Information security risk is increasing with the development of information network. More and more attention has been focused on. Since attack means become effective, information network is facing a crucial situation in the current complicated practices.China Post has constructed the POSTAL Comprehensive computer network, which can cover all over the country. This network can be used to deal with postal financial business, postal Comprehensive business, office management, postal internal telephone system, Videoconferences System and so on. Compared to other province, the scope and amount of transactions can be ranked on the top. With the development of postal informization and innovation of the postal deposit, more and more information need to be handled and the network risk will be confronted with a great challenge. Thus, network security construction should be emphasized in order to ensure postal information security.In this thesis, a method is proposed to construct the Sichuan postal comprehensive network security system and some technical plans related to the innovation of the network security are also illustrated. The network security and the current situation of Sichuan postal comprehensive network are considered at the same time in this method.The layout, construction, operation and maintenance of the Sichuan post network are taken charge by our department. We are making some plans and ready to put into practice. And I am responsible for the layout and design. The first stage of Sichuan postal network security has come to end in term of the design plan demonstrated in this thesis. Now, we are doing some preparations for the second stage. The related technical plans have been validated in the engineering practices. It may bring some benefits to other similar projects.
