一种基于角色的数据库安全访问控制方案的设计与实现

A Scheme Based on RBAC of Database Secure Access Control Designing and Realizing

在管理信息系统和决策支持系统的研究与广泛应用中,后台数据库的安全性问题至关重要。采用了基于角色访问控制模型的数据库安全性设计方案。该方案利用后台数据库的安全管理机制,结合具体角色实现了权限所及的安全访问控制,并成功地运用于"黑龙江防洪决策支持系统"等多个实际的工程项目中,有效地解决了安全访问控制问题。

In research and application of Management Information System and Decision Support System, database security is very important .The paper uses a database security scheme based on RBAC. The scheme integrates material roles ,realizes secure access control using database security mechanism, and applys successfully in some practical projects including ″Heilongjiang Preventing Flood Decision Support System″,resolves effectively the question of secure access control.
