数据仓库基于角色强制访问控制研究

Research on Role-based Mandatory Access Control in Data Warehouse

数据仓库基于角色安全模型得到广泛应用,但该模型没有对主体可信程度和客体敏感程度划分安全级别,没有实现严格的强制访问控制。本文扩展数据仓库基于角色安全模型和数据库多级安全模型,结合数据立方体格结构,提出数据仓库基于角色强制访问控制模型,对数据仓库实施严格强制访问控制,为数据仓库安全研究提供一种新思路。

Role-based security model for data warehouse has been widely used.But it does not implement mandatory access control.In this paper,role-based security model for data warehouse and database multi-level security model are extended.Together with multidimensional data cuboids lattice,role-based mandatory access control for data warehouse is proposed.The new model implements mandatory access control in data warehouse,and provides a new way to the study of data warehouse security.
