- Abstract
- In this paper we present an approach to modeling system-centric information in order to facilitate role engineering (RE). In particular, we first discuss the general characteristics of the information required in RE. Afterwards, we discuss two informational flow types among authorities involved in RE process, forward information flow (FIF) and backward information flow (BIF), together with the introduction of an information model which is greatly suitable for use in the backward information flow. System-centric information is incorporated in the information model and UML extension mechanisms are exploited for modeling the information. Not only can the information model provide those different authorities with a method for both analysis of resources and communication of knowledge in the RE process, but it can also help lay a foundation for successful implementations of RBAC.
