What topics are covered across the four days of the ISA/IEC 62443 course?
Over four days the course covers IACS fundamentals and networks, system security requirements and maturity models, establishing the industrial security programme, and incident response. Each block is anchored in a continuous case study.
Day 1 establishes the foundations: terminology, scope, key concepts, and IACS network architecture. Day 2 addresses system security requirements, maturity models, security levels, the threat landscape, access control, the supply chain, audits, and patch management.
Day 3 focuses on establishing and managing the security programme: risk assessment, policy development, and the IACS organisation. Day 4 works through internal training, incident response, security testing, monitoring, and other relevant sector standards. Each block combines structured explanation with hands-on exercises built on a continuous case study.
The sequence follows the real life cycle of an IACS security programme rather than the structure of the normative document, so participants leave able to plan and run a programme end to end rather than simply cite the parts of the standard.

Expert Insight
Day 2 is usually where the biggest shift in perspective happens: once participants see how security levels and maturity models interact with operational reality, control decisions start to make sense.
“The four days follow the real life cycle of an IACS programme, not the structure of the standard document.”
