Cyber-Physical Systems (CPS) integrate computing, networking, and physical processes, making them critical in applications such as smart homes, industrial control systems, autonomous vehicles, smart grids, and medical devices. Ensuring CPS security is essential, as vulnerabilities can have serious consequences. CPS share key security requirements with traditional IT systems-confidentiality, integrity, and availability-but also introduce additional challenges due to real-time constraints, interactions with physical processes, and safety considerations. Standard security practices include secure design principles, redundancy, continuous monitoring, resilient control algorithms, and rigorous verification and validation procedures. However, security techniques must be tailored to specific CPS domains. Some of the requirements may interact with each other, e.g., adding security mechanisms violating timely responses, or lack of security measures impacting safety. The complexity of securing CPS is further heightened by the integration of artificial intelligence (AI), which enables greater system autonomy in tasks like energy optimization and security monitoring. In this paper, we present results from two previous projects that focused on smart IoT systems and avionic systems, respectively. In both cases, arriving at solutions that combine many requirements is at the heart of the methodology. Based on this past work, we discuss open research directions.
