Security Issues in Data Warehouse
It tackles security issues in data warehouses for organizations, but is incremental as it provides a review without new methods.
The paper reviews security approaches for data warehouse environments, addressing vulnerabilities in storing sensitive data to aid decision-makers, but does not report specific results or numbers.
Data Warehouse 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 organizations business processes. A data warehouse environment must ensure that data collected and stored in one big repository are not vulnerable. A review of security approaches specifically for data warehouse environment and issues concerning each type of security approach have been provided in this paper.
