BusiROLE: A Model for Integrating Business Roles into Identity Management

The complexity of modern organisations’ IT landscapes has grown dramatically over the last decades. Many enterprises initiate role projects in order to reorganise their access structures based on an organisation-wide Identity Management Infrastructure (IdMI). This paper surveys role models and related literature and identifies different role properties. It shows that current role models are not feasible for their usage in IdMIs. By implementing one single type of role they fail to take business requirements and different role perceptions into account. This paper improves the current situation by developing busiROLE, a role model that integrates various types of roles, fulfilling businessas well as IT requirements, and is hence usable in IdMIs.
