The Research And Application Of SAAS Model’s Access Control

With the rapid development of cloud computing, SAAS(Software-as-a-Service)become popular to more and more customers. In SAAS model, supplies make thesoftware as a service, and rent it out to the enterprises who need it. This model hasmore advantages than traditional software sales model. But the security problem isone of the main factors which restrict the rapid development of SAAS. The users’ datawhich is managed by SAAS supplies may be subject to multiple threats. Theseproblems have been wildly concerned and researched.Because of multi tenant in SAAS model, the settings of departments and postsare different from company to company, and the requirements of role permissions aredifferent too. According to the characteristics of the SAAS mode, this paper proposesan access control model in SAAS mode, and combined with the method of accesscontrol in RBAC (Role-Based Access Control), the access control layer of the modelis designed. That not only make the permissions of users can be managed flexibility,but also reduce the risk of diffusion of permissions.At the end of this paper, Combined with the research results and thecharacteristics of warehousing management information system, I design andimplement a information system of warehousing management in SAAS model, themodules of user management and permission management have been designeddetailed with description.
