With the emergence of the digitization of information, ICT infrastructure and communications gave an unprecedented push towards the realization of truly interconnected passenger transport ecosystems at city-level. The emerging notion of multimodality supports a plethora of diverse transport services, typically offered from a central location. There however, the complex interconnected infrastructures ease the cyber-threats propagation while the underlying mosaic of fleets, personal hand-held devices and non-standardized data types increase the system's attack surface and require the authorities collaboration to proactively handle severe incidents. CitySCAPE leverages the skills and mature technology of its 15-partner consortium to systematically explore all different cybersecurity dimensions of multimodal transport. These dimensions will drive a characterization of the cyber-threats in the ICT multimodal transport, extended to the close-by power and financial sector. Innovative software tools will be introduced to estimate the threats propagation in the system. Then, CitySCAPE will realize a modular software toolkit enabled to be seamlessly integrated into any multimodal transport system to: a)detect suspicious traffic-data values and identify persistent threats; b)evaluate an attack's impact in technical and notably in financial terms; c)combine external knowledge and internally-observed activities to enhance the predictability of zero-day attacks; d)instantiate a networked overlay to circulate informative notifications to CERT authorities and support their interplay. The CitySCAPE solution will be tested over a timely set of use-cases involving ticketing applications, cyber-fraud and location data in the regional transport system of two European cities, where extensive experiments will showcase its effectiveness. The findings will steer training sessions of expert/non-expert audience and shape a strong standardization contribution to security (labelling) protocols.
