CPS- Synergy- Collaborative Research- Threat-Assessment Tools for Management-Coupled Cyber and Physical Infrastructures

Wide-area management of terrestrial scale infrastructures often involves human operators, who are sandwiched between physical-world systems and cyber- assets.  These Management Coupled Cyber-Physical Infrastructures (MCCPIs) are subject to diverse threats that can propagate across network elements.  In this research effort, a layered network modeling paradigm for MCCPIs is developed, and threats to cyber, physical, and human assets are modeled at several resolutions.  A tool suite is then developed for threat assessment and mitigation, with three network functions: Target, Feature, and Defend.  Several activities to promote broader impact, including technology transfer to transportation scientists and student training on Internet-of-Things applications, are pursued.
