Abstract
To assist Defence Research and Development Canada as it develops cybersecurity strategies for cyber-physical systems (CPs), NRC Knowledge Management conducted a literature survey and analysis of 2,220 publications drawn from scientific and technical datatbases. The survey found that research attention is gradually shifting from conventional approaches to cybersecurity, such as intrusion detection, to those that include a more holistic and integrated view of both cyber and physical aspects. Modeling and simulation play a key role in developing and testing security systems. Various CPS-specific modeling methods, such as those that incorporate state estimation or intelligent, interactive layers are also being explored. Because of the criticality of most cyber-physical systems and their role in national security, many CPS modeling solutions specifcally address safety, reliability and risk management; resilience and survivability are key. Key players in CPS cybersecurity are U.S. academic institutions and government laboratories, but commerical enterprise is also active. Much of the current research is being driven by security needs of wireless sensor networks and electrical grids, but other sectors, such as the automotive industry, are also participants. Because innovations may first be seen and research partnerships may thrive in domains that are not overtly military, it is recommended that DRDC maintain a broad perspective while pursuing its own research goals for CPS cybersecu
