Data Warehouse (DWH) provides storage for huge amounts of historical data from heterogeneous operational sources in the form of multidimensional views, thus supplying sensitive and useful information which help decision-makers to improve the organization’s business processes.

A review of security approaches specifically for data warehouse environment and issues concerning each type of security approach have been provided in this paper.
