IEC 62443-2-1:2010
Security for Industrial Automation and Control Systems — Part 2-1: Establishing an IACS Security Program
IEC 62443-2-1 defines the elements required to construct a comprehensive cybersecurity management program for industrial automation asset owners. Closely mirroring ISO 27001 but adapted to OT operational realities, it mandates business risk assessment, security policy formulation, staffing organization, asset inventory governance, incident response, and business continuity in industrial plants.
Scope & Applicability
Applies to asset owners (plant operators, utility operators) responsible for the facility's overall industrial automation infrastructure.
Non-Coverage Boundaries
Does not specify component-level engineering design or third-party service provider internal security requirements.
Key Clauses & Control Requirements
IACS Cybersecurity Management Program
Establishing organizational governance, management review, roles and responsibilities across IT and plant OT engineers.
Required Regulatory & Audit Evidence Artifacts
- [✓]IACS Security Management System Policy Document
- [✓]Asset Owner OT Cybersecurity Risk Assessment Matrix
- [✓]Plant Incident Response and Industrial Continuity Plan
“Asset owners cannot outsource accountability. Even if equipment is vendor-maintained, the plant manager is legally responsible for the facility's cybersecurity program.”
