Analysing non-malicious threats to urban smart grids by interrelating threats and threat taxonomies

A comprehensive study of the smart grid threat landscape is important for designing resilient urban grids of the future. To this end, an analysis could first cross reference threat categorizations and interrelate treat events on the basis of threat lists that complement each other. This paper show how to cross-relate threat taxonomies and analyze relations between threats and system components to reasonably link diverse threats to a smart grid. We illustrate how one can look beyond a specific threat by (1) relating threat sources from one taxonomy to threat lists from other taxonomies; (2) analyzing how threats can be cross-related to identify possible scenarios of undesirable events; and (3) assigning threat categories to system components. These steps in sequence or individually aim to provide input to threat identification and (thus) risk assessment tasks. This paper focusses on threats listed in the IRENE research project and relates them to threat taxonomies used in the AFTER and SESAME projects which focused on smart grids as well.
