Study And Application On Firewall System Of Jiangxi Province Local Taxation Bureau

Being the background of "The Project of security management jiangxi local taxation Bureau" and based on the theoretic reach and the practice of appliance,this paper is written in combining the net speed and the net efficiency for setting up the networks security of firewall System,and building the area networks security in the jiangxi local taxation system.First the paper mainly expatiates the basic viewpoint of networks security, and the basic concept and classification of the firewall system,then deeply analyses and expatiates the piont technology about the firewall system. Meanwhile,the paper discusses the frangibility and the localization of the firewall,and compare the firewall arrangements and the firewall system installation. Based on the theoretic of the firewall rule and the firewall policy, the paper described the arithmetic of the firewall rule.Next,The paper introduces the frame and technical characteristics about the jiangxi local taxation wide area network, with the net work situation, the paper analyses the networks security problems and the network companies.we found it is common with the wrong operate, the network virus and so forth. So we decided to optimize the firewall filtering rules based on the firewall principle and the firewall technology, and than put forward the arithmetic of optimize the firewall filtering rules based on the statistical chart.
