Assessment Of Export Tax Rebate System Analysis And Design

At present, with the further proceeding of information technology application in the tax system, the platform of tax applications tends to be data-clustered. Considering the fact that the downflow and upflow of most of the working data of tax applications among different levels of tax authorities are transmitted via computer network, the capacity and safety of the network largely influences the system to be well functioned. Meanwhile indicated according to the statistical result that, 99.9% security events come from with the network in, but only then 0.1% security event come from exterior. So, according to the tax affairs system actual need, the development deployed a set of related tax system network security management system already was imminent.This article introduced first the domestic and foreign existing network management agreement and the network management system overall survey, according to the investigation and study material, has analyzed the tax affairs system network environment and the application system present situation, thus obtains the system the design demand. And further acts according to this design demand, how discusses through the SNMP agreement programming management network equipment, realizes to the tnetwork computer monitoring management technical principle, and has carried on the test to the correlation procedure programming.This article then carries on the system design to the tax system network security management system. According to the system basic design principle, to the system design goal, the architecture, the main module has carried on the analysis design. The system based on the C/S structure development, by installs the client side (Client) software and installs on various computer equipment in manages on the server the administrative center (Server) software two parts to carry on function processing, practices the client authorization system, may according to need to forbid some without the authorized computer use network resources, prevented initiates the attack without the authorized user through the network to the system. This system also has the examination simultaneously connect the internal and external network the computer, the support convenient level company manages and so on the functions. And acts according to the overall project design, has carried on the analysis design to the tax affairs network security management system management system various functions concrete realization.Finally, this article has carried on the technology assessment to the tax system network security management system system effectiveness and the security, thought the system conforms to the design demand in the security potency.
