Ipsec-based Tax System Network Security Audit System Research And Design,

In order to strengthen the supervision and protection of tax revenue sources, to achieve the modernization of tax administration, tax authorities in China will be the reform of information technology as a breakthrough, vigorously implement the "science and technology tax" strategy. Modernization of tax administration needs the support of information technology, and tax information possible without the support of computer network systems. Tax revenue collection network as a national tax department of electronic data exchange platform, its security is very important. Therefore, the state tax system, computer network security audit of the research is very important.Tax system network as large and complex network systems, resulting in the existence of many network security blind spots and hidden dangers. Through analysis, we can see the incidence of national tax network security issues mainly due to these causes: the national tax system network in the absence of complete security and early warning system; for network transmission of data without security measures, resulting in information disclosure; user authentication lack of control of illegal users without the appropriate measures.This paper first made national tax network security risk analysis, then the National Tax network environment, operating system, database and application security audit conducted needs analysis, requirements analysis in the security audit, based on our research and design a species to the core of the national tax system IPsec network security audit system. Paper, we have the function of the system structure, system network model and architecture model is designed. Then the system model functions of each module in detail design. Finally, vision system model of the deployment were discussed. Tax system through the audit of internal network security, we can be sure of this system security, security warning, authentication and data confidentiality is feasible, it should present a variety of national tax network security issues. The innovation of this thesis or main characteristics of these: the IPsec uses advanced technology as the core of the security audit system to avoid several of the current audit system the model is really the authenticity and legitimacy of the audit data. Security audit system is an open design; contribute to the system later extensions.This article in the national tax system, network security audit system for current and future state tax for some time the need for network security audit should be feasible, will be the future of the national tax on early warning and protection of network security have a positive influence.
