The Applied Research Of Information Security Technology Based On ASP Service Platform

ASP(Application Service Provider) is a model of operational leasing. Enterprisescan hire computers and software systems of ASP to manage their operations. Bydoing this, the enterprises gain a substantial savings from the purchase and operationof IT products technology funds. So ASP has become the preferred model ofManufacturing industry informationization.As a typical Web application, security has become the most important aspectwhich had restricted the development of ASP. A favorable security policy canpromote the development and application of ASP. Although most of the ASPproviders have taken correlative security measures to protect ASP, the research ofASP security is limited on the surface layer of physical security, network security,data encryption etc. This has limited the research of ASP security and left it no abruptdevelopment. The thesis breaks through the limitation and analyzes the ASP securityfrom three tiers of B/S structure which includes client tier, application service tier anddata-base tier. The thesis emphasizes on the importance of the ASP security policy.Then we put emphasis on the security of application service tier using the ASP.NETtechnology.According to the ASP service platform the physical structure and the logicalorganization, the architecture and the characteristic of Networked Manufacturing ASPservice platform are analyzed thoroughly, had understood system security hiddendanger and safe threat which possibly faces under the current movement and thedeployment environment, combined with the latest network security technologyand.NET security mechanism, a security model of Networked Manufacturing ASPPlatform is put forward from the developer's view, and the detail design andrealization of the security model is given. The structure of the paper is as follows:First, conceptions of networked manufacturing and ASP Service, the architectureand function module of Networked Manufacturing ASP Platform based onthem are introduced, and the importance of research of platform security is analyzed.Next, the ASP service platform physical structure and the logical organizationare analyzed, the potential threat of the system is analyzed in various aspects, and thefoal of system security is put forward. At the same time, the function principle ofsystem, various security solution provided by.NET and the latest network security technology are analyzed, hased on intrinsic characteristics of platform, a securitymodel which take the applications safely of customer end, server end, database threelevels as well as secret channel as main body based on B/S overhead construction isestablished for Networked Manufacturing ASP Platform.Then the detailed design andthe realization of this security model and how one implements this security modelstep by step in ours platform is introduced.Finally, in conclusion section, the research content and conclusionaresummarized, and the core technology, application prospect as well as the furtherresearch work are looked forward.
