Research on the Role-Based Access Control Model and Data Security Method

For management of massive data and centralized network, the data security research team has become a central issue. Role-based access control (RBAC) is a common practice to control access to sensitive data. This article uses Flex and C# to develop an RBAC model, which can make data management more flexible. Concentrating on data security, this article presents the layer structure and model design for standardized management of security access. This article also implements detailed approaches for data security by verifying parameters and codes, access control, preventing illegal users and using oracle parameters and stored procedures for database security technology. In addition, an empirical study was conducted to assess effectiveness and usefulness .
