Organisations interact with each other for mutual benefits. Federation refers to one such interaction where each organisation functions independently yet is bound by contracts with others. Rural business process outsourcing (RBPO), multi-institution course management system, and video streaming services are a few examples of federations. Security of shared resources is an important concern in such scenarios. Since each organisation is independent, it is difficult to communicate the precise semantics of access control policies to other participating organisations for correct enforcement. Over the years, ontology has been employed across different domains and can be used for sharing access control semantics across organisations. In this work, we describe a network-aware digital object-based access control model (NA-DOBAM) as an extension of the popular role-based access control model to address the specific needs of security in federations. The relationship between web ontology language and NA-DOBAM model is studied. We have used an ontology-based approach for specification and implementation of NA-DOBAM in the context of RBPO where the access control policy depends on the structure of the users and objects along with the network state. We demonstrate the applicability of ontology for RBPO case studies for extracting meaningful access control information using queries as well as for enforcing access control policies including separation of duty and delegation
