Paper Abstract:	Generally, Information Systems security is taken into consideration once the system has been built, it is in operation and security problems have already arisen. This kind of approach, called “penetrate and patch” is being shifted by methodologies that introduce security in the systems development process. This is an important advance but, unfortunately, methodologies incorporating security are based on an operational environment and not on an analytical one. Therefore, they do not include multidimensional modeling approaches to work with Data Warehouses (DW), Multidimensional Databases and On-Line Analytical Processing (OLAP) applications. This paper makes a comparison of secure information systems design methodologies and puts forward an extension based on the Unified Modeling Language (UML) for multidimensional modeling. Besides, an example of the application of the extension proposed is shown. Neither of the studied methodologies address the security aspect comprising all stages of the system development cycle nor considers the introduction of security in multidimensional modeling. We propose an extension which tackles these problems and allows us to introduce security elements into a multidimensional application through the standard mechanisms of UML extension. As a result, it avoids developers to waste time to adapt themselves to a new methodology and achieves a more robust specification.
