Consequences of Security Aspect Interactions on Aspect-Oriented Modeling

Non-functional concerns are present in all software solutions and products. While the functional requirements most often drive the development of models in Model Driven Development (MDD), the modeling of non-functional concerns, such as security, is equally important for a high quality solution. The security concerns within a solution are often crosscutting, non-orthogonal and of a diverse nature. There exist a variety of combinations of security solutions, which in many cases significantly increase the solution complexity. Aspect-Oriented Modeling (AOM) is an MDD approach that helps a software engineer to develop higher quality solutions by considering various requirements independently before composing the separate sub-solution models with the core functionality. This paper looks at some of the possible aspect representations for the common security concerns of authentication, authorization, auditing, and data privacy. The goal is to develop some of the interaction concepts needed for an effective AOM approach.
