Cyber-physical system

Cyber-physical systems (CPS) are integrations of computation, networking, and physical processes, enabling real-time sensing, analysis, and control of the physical world through sensors, actuators, and networks. Originating from Industry 4.0 and IoT, CPS aims to create smarter, autonomous, and adaptive systems. Unlike traditional embedded systems, CPS emphasizes network connectivity, autonomy, and deep interaction with the physical environment. In enterprise risk management, CPS's cross-domain nature, merging IT and OT, necessitates considering both information security (referencing ISO/IEC 27001) and functional safety (e.g., ISO 26262 for automotive, IEC 62443 for industrial control systems). NIST Special Publication 800-160 Vol. 1, "Systems Security Engineering: Considerations for a Multidisciplinary Approach in the Engineering of Trustworthy Secure Systems," provides detailed guidance on CPS security, emphasizing the integration of security considerations from the design phase to address potential cyberattacks or system failures, ensuring system resilience and reliability.

In enterprise risk management, CPS application requires a comprehensive framework. Firstly, enterprises should conduct risk assessments following ISO 31000 principles, identifying CPS-related cybersecurity threats (e.g., cyberattacks impacting physical equipment) and functional safety risks (e.g., thermal runaway due to Battery Management System (BMS) failure). Secondly, during system design and implementation, security by design principles should be adopted, referencing standards like ISO 21434 (Road Vehicles – Cybersecurity Engineering) or IEC 62443 (Industrial Automation and Control System Security). For instance, in automotive Cloud BMS, implement encrypted communication (TLS 1.3), multi-factor authentication, and the principle of least privilege to ensure data transmission and access security. Finally, establish continuous monitoring and incident response mechanisms, leveraging big data analytics and AI to monitor CPS operational status in real-time and detect anomalies. For example, monitoring BMS data can increase battery anomaly detection rates by 30% and reduce response time to potential safety incidents by 20%. Winners Consulting assisted an automotive component supplier in implementing a CPS risk management process compliant with ISO 26262 and ISO 21434, boosting their product compliance rate in international markets to over 95% and reducing recall risks from cybersecurity vulnerabilities by 15%.

Taiwanese enterprises face several challenges in implementing Cyber-physical systems (CPS). Firstly, **high technical integration complexity**: CPS involves the convergence of IT, OT, cloud computing, AI, and other technologies, demanding high levels of cross-departmental collaboration and technical capabilities. Secondly, **lack of cybersecurity talent and resources**: There is a scarcity of professionals with integrated OT and IT cybersecurity knowledge, and SMEs often have budget constraints for cybersecurity. Thirdly, **regulatory compliance and alignment with international standards**: Taiwan's regulations for CPS-related cybersecurity and functional safety are still evolving, making alignment with international standards like ISO 21434 (Automotive Cybersecurity) and IEC 62443 (Industrial Control System Security) challenging. To overcome these, enterprises should: 1. **Establish cross-functional collaboration mechanisms**: Form project teams comprising IT, OT, R&D, and legal departments, adopting agile development and DevSecOps. 2. **Engage external expert consultants**: Seek professional consulting firms like Winners Consulting, experienced in international standard compliance, to assist with cybersecurity risk assessments, talent training, and solution implementation, bridging internal resource gaps. 3. **Phased implementation and standardization**: Reference the NIST Cybersecurity Framework (CSF) or ISO/IEC 27001 to build a CPS security management system in phases, internalizing international standards into internal operating procedures. Priority actions include risk assessment and cybersecurity architecture planning (within 6 months), followed by implementing security monitoring and response mechanisms (within 12 months), and long-term continuous optimization and talent development (within 24 months).
