OT Security All-in-One, Volume 3

OT Security All-in-One, Volume 3: IEC 62443, Governance, Compliance, and Board is a 380-page professional reference work for the GRC manager, the CISO and the board advisor. An OT security programme that cannot be proven does not exist as far as a regulator, an auditor, an insurer or a board is concerned; this volume is about making industrial cyber risk visible, governable and defensible.It shows how to run consequence-based and bow-tie risk analysis for cyber-physical systems, quantify OT risk for executives, build an audit-ready evidence base, and translate engineering risk into board risk using the three-lines model, clear risk ownership across the CISO, CIO, COO, engineering and safety functions, and an OT cybersecurity strategy and operating model.The IEC 62443 chapters form a working reference to the standard: its structure, purpose and scope; 62443-2-1 security programme requirements for asset owners; 62443-3-2 risk assessment and system design with zones and conduits; 62443-3-3 system security requirements and the seven foundational requirements; 62443-4-1 and 4-2 secure product development; and security levels SL-T, SL-A, SL-C and SL-R. Regulation chapters map NIS2, NERC CIP, the EU Cyber Resilience Act and sector obligations onto the programme.Every chapter follows the same practitioner rhythm: objectives, a scenario (often an audit), a plain-English explanation, a technical deep dive, a verified real-world incident, common failure patterns, a controls-and-evidence table, the board-level implication, a checklist, review questions and key takeaways. The Volume 3 review chapter doubles as an index into the parts you need.Written for CISOs, CIOs, COOs, OT security architects, industrial control engineers, SOC leaders, GRC managers, auditors, board advisors, critical infrastructure operators, consultants, suppliers and system integrators responsible for environments where cyber incidents can become physical incidents.Key topics include: IEC 62443; OT governance; OT risk quantification; zones and conduits; security levels; NIS2; NERC CIP; Cyber Resilience Act; board reporting; audit evidence; OT compliance; operational technology.
