Interoperability In Pervasive Enterprise Information Systems: A Double-Faced Coin Between Security And Accessability
Résumé
As transparency becomes a key requirement for assuring service quality and user satisfaction, Enterprise Information Systems are seeking to become pervasive in order to deal with the heterogeneity problem of their sub components. In this position paper, we expose the challenges that face Enterprise Information Systems in achieving better data integration, representation and management, while ensuring homogeneous interaction between different software sub components, improving the interaction between different customers and business partners and providing services on different terminals with dynamic connectivity constraints. Finally, we highlight the importance of applying adaptive, proactive and interoperable access control policies that would differentiate between providing local system users with full data accessibility and providing external users with multi-levelled security controls.
