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. The paradigm used is formal concept analysis, which aim at extracting implicit lattice from binary relation.
