Design And Implementation Of Network Security Mechanism For Tax Information System Of Harbin Economic Development Bureau

With the continuous innovation of China's tax information system,today's tax system information construction has reached a certain scale,in the use of more convenient.But with the process of social information,more and more network viruses and criminals on the network,the impact of China's tax information network system,a serious threat to the tax system of computer network security,in response to this situation,in order to Effective protection of our country's tax information system,first of all to the tax information system to strengthen the management of the weak areas,followed by the relevant tax officers to carry out network security management training to enhance their awareness of security awareness,and for the tax information system as a whole To upgrade the security,to ensure the safety of the system to ensure that its daily work in the smooth operation.This paper designs and realizes the network security mechanism of tax information system for the status quo of network security protection system of tax information system of Harbin Economic and Taxation Bureau.Firstly,it analyzes and analyzes the security risks and threats faced by the network during the application of tax information system,and makes an in-depth study on the existing network security policy design of tax information system.On this basis,combined with the actual network security requirements of the land tax and tax information system of Harbin Development Zone,this paper analyzes the detailed requirements and feasibility analysis of the functional modules of the network security mechanism designed in this paper.Then,the design and development of the network security mechanism of the tax information system are carried out,including the architecture design,digital signature and signature,certificate management,content audit,behavior alarm,log management and traffic analysis of the system security mechanism,and its background database To design.Based on the security requirements of the land tax and taxation system of Harbin Economic Development Zone,this paper establishes the security solution based on information security technology such as digital signature verification,information encryption,certificate management and identity authentication,completes the design of the tax information system network security mechanism,Realize the sharing and exchange of information between the city tax system and the external network of the tax system.Finally,the system test and practice show that the network security mechanism designed and implemented in this paper can integrate the network information security management technology with the tax application system,encrypt or sign the tax information data,authenticate the user identity of the tax information system,Real-time monitoring of the user's network behavior,a good guarantee of tax information confidentiality,integrity and non-repudiation,to minimize the tax information system external network security risks.
