Abstract

The effectiveness of an enterprise access control framework depends upon the integrity of the various components or the building blocks used in that framework. The essential components of that framework are: (a) an Enterprise Access Control Model (b) a Validation mechanism to verify the enterprise access control data developed based on that model, for conformance to the model as well as domain-specific policy constraints and (c) a mechanism to map the enterprise access control data into formats required by native access enforcement mechanisms in the heterogeneous application systems in the enterprise. In this paper we chose the Role-based Access Control Model (RBAC) as a candidate for the enterprise access control model. We develop an XML Schema of an RBAC Model for a specific enterprise context and demonstrate the use of schema features to specify structural and some rudimentary domain constraints. We then annotate that XML Schema of an Enterprise RBAC Model to demonstrate specification and enforcement of some important domain-specific policy constraint using the Schematron language.
