Model driven architecture for modeling of logical security based on RBAC approach

Abstract

This paper presents an approach of role-based access control (RBAC) for information systems with the use of MDA (Model Driven Architecture). The main purpose is to join the concepts of MDA approach with the concepts of access control models, in particular with the concepts of access control based on roles and on usage concept. To reach this objectives the appropriate solution was created to model the extended RBAC model and URBAC model with the use of concepts and tools of software engineering, in particular MDA methodology and UML (Unified Modeling Language). The presented approach was developed for role engineering in the aspects of logical security of information systems.
