The proliferation of interconnected and networked medical devices has resulted in the development of innovative Medical Cyber-Physical Systems (MCPS). MCPS are life-critical, distributed systems that are utilized to monitor and control healthcare organizations in order to provide a more coordinated, cohesive care-continuum focused on the whole patient resulting in better outcomes, and a happier, healthier patient. Medical Cyber Physical (MCPS) systems are life-critical, networked systems used to monitor and control healthcare and medical devices in order to provide more coordinated and cohesive care for the patient. Cyber-securing MCPS is difficult due to their complex and interconnected nature, and this project sets about analyzing current security requirements for MCPS using an ontology and exploration techniques, and developing a risk assessment and monitoring framework to better secure such systems.
