ISA/IEC 62443 Lead Implementer Training — Lesson 1: IACS Concepts, Standards, Roles, Zones, Conduits, and Governance

Learning Objectives

• Interpret the principles, requirements, roles, and dependencies shaping iacs concepts, standards, roles, zones, conduits, and governance.
• Apply the workflow and produce industrial security architecture and governance map that another practitioner can review.
• Analyze “a safety-related controller is absent from the security inventory” and recommend a proportionate, supported response.

Detailed Topics

• IACS security concepts
• ISA/IEC 62443 series
• asset-owner roles
• supplier roles
• zones and conduits
• security governance
• system inventory
• programme scope
• Competence, communication, governance, documented information, risk, validation, and follow-up considerations

Instructor Demonstration

The instructor demonstrates the iacs concepts, standards, roles, zones, conduits, and governance workflow, identifies the applicable inputs and responsibilities, records checkpoints in industrial security architecture and governance map, and contrasts the accepted state with a condition where a safety-related controller is absent from the security inventory.

Hands-On Exercise

Complete a controlled implementation, audit, assessment, or foundation exercise for IACS Concepts, Standards, Roles, Zones, Conduits, and Governance. Establish scope and criteria, collect or create evidence, examine “a safety-related controller is absent from the security inventory,” reach a supported conclusion, and preserve the result in industrial security architecture and governance map.

1. Confirm objectives, scope, roles, criteria, stakeholders, and expected outputs.
2. Perform the planned activities while recording assumptions, evidence, and decisions.
3. Test a normal case, an exception, and a follow-up or improvement condition.
4. Document conclusions, owners, due dates, escalation, and verification requirements.

Scenario Analysis

• Identify the requirement or principle with the strongest influence on iacs concepts, standards, roles, zones, conduits, and governance.
• Compare two defensible responses and explain their governance, risk, and evidence trade-offs.
• Determine how industrial security architecture and governance map should be approved, retained, reviewed, and updated.

Troubleshooting Guidance

Separate missing evidence from ineffective practice, and distinguish a documentation issue from a control, process, governance, or competence failure. Use industrial security architecture and governance map to trace the earliest divergence. Treat “a safety-related controller is absent from the security inventory” as a hypothesis until the response is validated against the applicable requirement and intended outcome.

Validation Checklist

• The scope, criteria, stakeholders, and intended outcome for iacs concepts, standards, roles, zones, conduits, and governance are explicit.
• The industrial security architecture and governance map links statements and decisions to objective, reviewable support.
• Responsibilities, competence, communication, risk, legal duties, and change impact were considered where relevant.
• Findings, corrective actions, monitoring, review triggers, and improvement ownership are clear.

Lesson Outcome

Learners can apply IACS Concepts, Standards, Roles, Zones, Conduits, and Governance, explain the reasoning used, and defend the result through industrial security architecture and governance map.
