Cyber Physical Systems

Cyber Physical Systems (CPS) are systems where physical processes are digitally monitored and controlled through integrated computational intelligence and networking. Unlike traditional IT systems, CPS risks extend to the physical realm, potentially impacting human safety and infrastructure. According to ISO/IEC 27001 and the NIST Cybersecurity Framework, CPS requires a unified approach that covers both information security and operational technology (OT) safety. GDPR Article 25's Privacy by Design principle is particularly critical here, as any data-collecting sensor in a CPS environment must be assessed for privacy risks before deployment. This necessitates a holistic view of the entire system-of-systems, including legacy hardware and cloud-connected components.

Effective CPS risk management involves three key steps: first, conducting a comprehensive asset-and-data-flow inventory using ISO/IEC 27701 standards; second, performing contextual DPIAs to identify privacy risks unique to the physical environment, such as unauthorized tracking via IoT sensors; third, implementing real-time monitoring and incident response as outlined in the NIST CSF. For example, a Taiwanese automotive supplier implementing CPS across its production lines saw a 30% reduction in data-related compliance incidents within six months by applying these principles. The key is to integrate the DPIA process into the continuous improvement cycle of the Information Security Management System (ISMS).

Taiwan enterprises typically face three challenges: regulatory ambiguity (navigating the intersection of the Taiwan Personal Data Protection Act and GDPR), technical skill gaps (IT/OT convergence), and supply chain vulnerabilities. To overcome these, enterprises should first establish a cross-functional governance team including IT, OT, and legal experts. Second, they must adopt international standards like ISO/IEC 27701 to ensure a common language for privacy controls. Third, a rigorous vendor management program, including security-by-design requirements in procurement contracts, is essential to mitigate risks from third-party CPS components. A phased approach starting with a 90-day pilot program is recommended for sustainable implementation.
