Abstract: In order to solve the network safety, share, security grade protection and the further needs of Beijing meteorological information, a set of information and network protection solution were proposed from the security idea, management and technology on the basis of the analytical results of the living network safety risk. The results indicate that safety domain should be built in terms of safety grade division in order to solve the network conjunction problem of office network, operational network and Internet. Security evaluation and reinforcement should be run through the total information system. Accessed VPN (Virtual Private Network) terminals causing the dubious network border are restricted by the network security joint defense’s mechanism. Information system is divided into various grades according to its attribute and damaged object as well as damaged extent. This paper provides some good and useful ideas for the customization design and implementation under the complex meteorological network and information security environment conditions.
