Model-based Specification and Validation of Security and Dependability Patterns
Résumé
The requirement for higher Security and Dependability (S&D) of systems is continuously increasing, even in domains traditionally not deeply involved in such issues. In our work, we propose a modeling environment for pattern-based secure and dependable embedded system development by design. Here we study a general scheme for representing security and dependability (S&D) design patterns whose intention specification can be defined using a set of local properties. We propose an approach that associates Model Driven Engineering (MDE) and formal validation to get a common representation to specify patterns for several domains. The contribution of this work is twofold. On the one hand, we use model-based techniques to capture a set of artifacts to specify patterns. On the other hand, we introduce a set of artifacts for the formal validation of these patterns in order to guarantee their correctness. As an illustration of the approach, we study the authorization pattern.
