This white paper explores real-world cyber risks for operational technology (OT) networks and maps them to the specific requirements of the IEC 62443 standard. Findings from risk analyses and continuous monitoring projects in OT networks of critical and industrial infrastructures are mapped to the standard requirements highlighting the importance of a multi-layer defense-in-depth approach for industrial automated control systems (IACS).
Finally, this white paper explains how dedicated OT monitoring with anomaly detection enables industrial companies from all sectors to implement defense-in-depth cybersecurity and a sound risk assessment process for their OT.
