Securing Web OLAP Based on RBAC Model

This paper proposes an access control and authentication infrastructure for accessing data in a multi data warehouse environment. We employ single sign on for authentication and role based access control (RBAC) for authorization. When users submit OLAP queries to the data warehouse, the authorization rules are enforced. In our approach, we use multi-agent systems to automate the authentication, authorization and accounting stages when accessing multi-data warehouse. For the implementation, A-Cold system prototype is developed to validate our proposed model.
