Dynamic environments make access control policies difficult to implement and evolve. This thesis focuses on the security and privacy provisions in a restricted organizational environment through access control mechanism. To address some of the current limitations of traditional access control models, we propose a knowledge-based architecture for Role-Based Access Control for project oriented environments based on Semantic Web Technologies. The solution includes representation of the semantics of the organization and its access control mechanism as an ontology exploiting the Web Ontology Language. Access to the resources is controlled by defining differential access rights formulated based on the roles of the individuals, and the departments, projects and groups they belong to. The expressivity of the knowledge base is further enhanced by executing semantic web rules using Pellet OWL-DL reasoner over the designed ontology. The ontology is designed to cope with organization restructuring with minimal efforts. To validate the proposed solution, the component architecture and functionality of its simple yet powerful implementation, MetaDB is described. 2010-11-02 English text The Ohio State University / OhioLINK http://rave.ohiolink.edu/etdc/view?acc_num=osu1285036690 http://rave.ohiolink.edu/etdc/view?acc_num=osu1285036690 unrestricted This thesis or dissertation is protected by copyright: all rights reserved.
