Cyber Physical Systems (CPS), are embedded systems composed of computing elements as well as physical processes. In the past, CPS were proprietary and not connected to the cyber space. With the advent of networked control systems to enable better operations and monitoring of the physical processes, these systems are increasingly becoming part of cyberspace. Connection to the cyber space enables effective management of public infrastructures such as public transportation, smart grid and water treatment facilities.
However, these advantages come with new security challenges. Attacks on CPS may lead to performance degradation to complete shutdown, or even equipment damage depending on the knowledge, goals and resources of the attacker. Most work in area of CPS security focuses on the cyber part and attempts to ensure secure exchange of information across controllers, sensors, and actuators. The nature of security threats and attacks in a CPS, is different from those found in pure cyberspace. Threat models have evolved significantly and the fact that any successful attack could be fatal as it’s more than a computer being hacked and disturbs the physical process may result in dangerous scenarios.
It is not only about the consequences of attacks but the fact that besides cyber attacks, attacks on physical devices are also possible. Hence understanding the physical part, and how it could be compromised, is essential to ensure CPS security. An adversary may add, remove or replace some physical components which may result in severe consequences. Thus focus ought to be on both physical and cyber domains. SecCPS 2019 seeks novel submissions describing practical and theoretical solutions to securing CPS. Submissions may represent any application area for CPS. Hence, papers that are pertinent to the security of embedded systems, Internet of Things, SCADA Systems, Water Systems, Smart-Grid Systems, Critical Infrastructure Networks, Transportation Systems, Medical Devices are welcome.
