Abstract: ICT infrastructures are a critical asset in today's Information society. Legacy telecommunication systems easily collapse in the face of disruptions due to security incidents or natural disasters. Hence, there is an urgent demand for new architectures and technologies ensuring a more efficient and dependable support for various security missions, such as disaster relief initiatives, first responder operations, critical infrastructure protection, etc. In this paper we advocate the opportunistic networking paradigm to build a self-organizing overlay ICT infrastructure for supporting dependable crisis management services. Our opportunistic framework to “glues together” surviving parts of the pre-existing infrastructure with networks deployed on-demand and users devices, and supports dependable distribution of coherent, updated, and non-contradictory information distribution. Finally, to show the potential advantages of our solution, we present initial results on the performance of different types of opportunistic infrastructures, by particularly highlighting the gains of context-aware systems.

Abstract: Protection of society against natural and man-made disasters is high on the societal and political agenda. Effective crisis management is more important than ever. Nowadays, crisis organisations depend crucially on reliable telecom services, and unexpected failure of telecommunication may have serious consequences. In order not to be caught unprepared, crisis organisations should therefore perform a risk assessment on telecom availability. Unfortunately, assessment of availability risks of modern, multi-operator telecom services is difficult; information sources are unreliable, and the relevant information is uncertain and difficult to obtain. This paper describes some of these difficulties, as well as the requirements of availability risk assessment methods for crisis telecommunication services. The paper outlines a new method that can be applied without requiring full knowledge of the physical layout of the telecom infrastructure. This new method relies on telecom service diagrams as a tool for risk analysis and to facilitate dialogue among the analysts.

Abstract: Crisis organisations depend on telecommunication services; unavailability of these services reduces the effectiveness of crisis response. Crisis organisations should therefore be aware of availability risks, and need a suitable risk assessment method. Such a method needs to be aware of the exceptional circumstances in which crisis organisations operate, and of the commercial structure of modern telecom services. We found that existing risk assessment methods are unsuitable for this problem domain. Hence, crisis organisations do not perform any risk assessment, trust their supplier, or rely on service level agreements, which are not meaningful during crisis situations. We have therefore developed a new risk assessment method, which we call RASTER. We have tested RASTER using a case study at the crisis organisation of a government agency, and improved the method based on the analysis of case results. Our initial validation suggests that the method can yield practical results. © 2012 ISCRAM.
