Reusable security use cases for mobile grid environments

Due to the growing complexity of software development, developing software through systematic processes is becoming more and more important. Likewise, it is important that the development process used integrates security aspects from the first stages at the same level as other functional and non-functional requirements. In the last years, GRID technology has shown to be the most important one and it allows us to build very complex information systems with different and remarkable features (interoperability between multiple security domains, cross-domain authentication and authorization, dynamic, heterogeneous and limited mobile devices, etc). Traditionally, systems based on GRID Computing have not been developed through adequate methodologies and have not taken into account security requirements throughout their development, only offering security technical solutions at the implementation stages. This paper shows part of a development methodology that we are elaborating for the construction of information systems based on Grid Computing highly dependent on mobile devices where security plays a very important role. Specifically, in this paper, we will present the analysis phase, managed by reusable use cases through which we can define the requirements and needs of these systems obtaining an analysis model that can be used as input to the following phase of the methodology, the design phase of mobile Grid systems.
