Security Architecture for Tanzania Higher Learning Institutions’ Data Warehouse

In this paper we developed security architecture for the higher learning institutions in Tanzania which considers security measures to be taken at different level of the higher learning institutions’ data warehouse architecture. The primary objectives of the study was to identify security requirements of the higher learning institutions data warehouses and then study the existing security systems in and finally develop and architecture based on the requirements extracted from the study. The study was carried at three different universities in Tanzania by carrying out interviews, study of the existing systems in respective institutions and a literature review of the existing data warehouses systems and architectures. The result was the security requirements identified which lead to the development of the security architecture comprising security in source systems, data, and services to be offered by the DW, applications which use DW, networks and other physical infrastructure focusing on security controls like authentication, role-based access control, role separation of privileged users, storage of data, secure transfer of data, protective monitoring/ intrusion detection, penetration testing, trusted/secure endpoints and physical protection.
