General considerations on data warehouse security

There is plenty of information regarding research works on Data Warehouse (DW) management systems aimed at improving several aspects such as data modeling techniques, the physical level of modeled data, transactional processing... However, not too many efforts have been made related to security aspects. At present, there are methodologies to design DW, but security is not taken into account. On the other hand, there are techniques to design security but these techniques do not consider DW. Therefore, it is necessary to study the way to design secure DW. This paper puts forward general considerations on security (specifically, confidentiality) when designing DW.
