Cyber-Physical Resilience in ICS with IEC 62443
Year: 2026
Type: conference-paper
Abstract: Cyber-physical resilience is critical for industrial control systems, yet international standards such as IEC 62443 are typically applied as high-level guidance rather than as operational mechanisms influencing runtime system behavior. This paper addresses this gap by operationalizing selected IEC 62443-3-3 Foundational Requirements; System Integrity, Timely Response to Events, and Resource Availability for industrial cyber-physical systems. The standard's objectives are translated into measurable indicators, persistence-based decision triggers, and lightweight adaptive actions suitable for real-time industrial environments. The proposed approach is evaluated using a python-based simulation of a generic closed-loop industrial control system subjected to delayed command and integrity fault scenarios. Results demonstrate that IEC 62443-driven operationalization improves cyber-physical resilience by enabling timely response, early integrity violation detection, and structured recovery, while bounding performance degradation during attacks. These findings show that standard-defined resilience objectives can be systematically integrated into runtime decision logic without modifying the IEC 62443 standard, bridging the gap between compliance-oriented guidance and operational cyber-physical resilience.
