Abstract:
The distinguishing feature of Cyber Physical Systems (CPS) is the coupling of computational and physical systems, where embedded cyber systems monitor and control physical processes. CPS is responsible for an important role in critical infrastructure, and everyday life. They include smart networked systems with embedded sensors, processors and actuators that sense and interact with the physical world and support realtime, guaranteed performance in safety-critical applications. The cyber-physical nature, coupled with safety-critical application greatly increases the attack surface and the impact of cyber attacks. Understanding the interaction between various subsystems in a CPS is vital in evaluating its security posture and identifying the measures to mitigate threats. To that end, the ability to trace a CPS design from the requirements elicitation phase to the implementation phase, otherwise known as requirements traceability may prove to be invaluable. This paper presents an Ontological approach to requirements traceability in CPS by building upon our previous work on defining the Semantic Inference Model for Security in CPS using Ontologies (SIMON), a design framework for CPS systems.
