Abstract:
Eliciting requirements is one of the most important phases in software development, which can lead the project to success or to failure. Particularly, when it comes to security requirements, the main responsibles for specifying software system have a lack of knowledge at security policies and the mechanisms for achieving them. This article proposes and presents a stage-based methodology called REfIS that aims to guide requirements engineers through the elicitation requirement process of software system. The methodology consists of three phases: (1) dispersion of knowledge about a certain universe of study through Casual Layered Analysis (CLA), (2) creation of a future scenario using Futures Wheel and (3) extraction of requirements from the analysis of the generated scenario. Finally, this methodology will be applied and validated at the initial phase of the development of a real P2P backup System in order to extract requirements.
