Découverte automatisée de hiérarchies de rôles pour les politiques de contrôle d'accès

Abstract : Role-engineering is the task of discovering roles in a system. This task is essential in building efficient role-based access control policies. The classical approach in role-engineering is top-down. It relies on business process analysis to define roles from basic tasks, but ignore existing privileges. This approach is time consuming and expensive. This article presents a new automated role-engineering technique - a role-mining technique. Our bottom-up approach mines existing privileges to derive roles roles and their hierarchical relationships. Our efficient proposal relies on well-founded background and is money saving.
