Intentional Services Specification Enhancement with Scenario-Based Techniques to Analyze Security Threats

In this paper, we focus on threats elicitation from an intentional service specification. We are interested in security, and we make the hypothesis that a systematic analysis of threats during the requirements engineering (RE) phase can help to reduce the number of security threats and build more robust systems. We build a structure that couples two abstraction levels: the intentional and the functional one. The aim is to provide a framework to reason and document intentional service specification when dealing with threats analysis.
