Interconnected Safe and Secure Systems (IS3)
Summary
Aims – Interconnected systems: Define a generic reference model of a “resilient organisation” as a socio-technical entity operating a cyber-physical system (CPS) dependent on other CPS operated by their respective operators. Explore the role of higher fidelity models as a way of ranking the alternative ways of implementing a given reference model and research if credible simplified models are suitable for interdependency and dependency analysis. Explore issues of scale and composition by applying the generic infrastructure model in a multi infrastructure system.
Aims – Safety and security: Develop an understanding of the problems and priorities of industry in security-informed and safety issues and an understanding of how decisions are made at the moment that involve trade-offs and the combination of objective and subjective judgements. Continue to develop the justification framework based on Claims, Arguments, Evidence which integrates objective and subjective evidence and explicitly combines informal reasoning with formal model-supported deduction. Research model-based techniques to analyse systematically the trade-offs and dependencies that are often complex technically, organisationally and institutionally.
