Panel Session: Dependability and Security in Complex and Critical Information Systems Department of Communications and Information Engineering University of Murcia (Spain) The First International Workshop on Dependability and Security in Complex and Critical Information Systems DEPEND 2008 August 25-31, Cap Esterel, France Antonio F. Gómez Skarmeta University of Murcia Spain

DEPEND 2008 (Cap Esterel,France) 2 Challenges  Information System Management increase the complexity of the models to work with in relation to classical network management systems and PBNM  Need for flexible and powerful models for service provision, data governance and system configuration allowing for affordable management functions  Trust and dependability can not be built in isolation neither can it rely on technologies of one layer only, there is need to provide integrated view and considered some hierarchy of models  Interoperable (policy-aware) architectures from trusted communications to the application, including to the data; Web Service technologies to support interoperability.  Usage of a common models and abstraction of the underlying system providing and overlay view of IT the business objectives behind.  Architectural design to support the flexibility and the dynamicity of the trust management in a vertical approach from application to the network and data layer.

University of Murcia DEPEND 2008 (Cap Esterel,France) 3 Challenges  Dynamic in the trust relations to allow flexible and spontaneous trust relation to be created based on the communications needs. Confederation concepts  There is a need homogeneous naming of entities (natural and legal persons, objects, virtual entities, devices, content, processes, applications, etc) and trust attribution schemes (identity management, authentication, authorization, accountability, reputation).  Semantic security layer need to be considered as an additional component in the trust relation to allow the possibility to enrich the trust models  Internet of things implies to be able to associate trust and behaviours tags to the digital objects and their relation
