Abstract

Knowledge centric management (KCM) has become a key strategy for competitive edge. As an essential of KCM, an enterprise ontology represents the knowledge of an organization. Thus, the need for securing enterprise ontologies (EO) becomes imperative. Adequate access control is a major component of ontology security. However, access control for EO is largely neglected in information systems (IS) literature. This paper presents the first research to fill this gap. I propose five requirements for good access-control solutions for EO. The proposed solution offers an architecture framework that meets the five requirements. Semantic Web technology is used to build context-aware access controls into EO. My proposal includes a novel resolution for policy conflicts. This study provides the first design of fine-grained and dynamically-adjusted access authorizations.

Building Context-Aware Access Control In Enterprise Ontologies

Knowledge centric management (KCM) has become a key strategy for competitive edge. As an essential of KCM, an enterprise ontology represents the knowledge of an organization. Thus, the need for securing enterprise ontologies (EO) becomes imperative. Adequate access control is a major component of ontology security. However, access control for EO is largely neglected in information systems (IS) literature. This paper presents the first research to fill this gap. I propose five requirements for good access-control solutions for EO. The proposed solution offers an architecture framework that meets the five requirements. Semantic Web technology is used to build context-aware access controls into EO. My proposal includes a novel resolution for policy conflicts. This study provides the first design of fine-grained and dynamically-adjusted access authorizations.
