IEC 62443 vs ISO 22000
IEC 62443
International standard for IACS cybersecurity lifecycle and risk management
ISO 22000
International standard for food safety management systems.
Quick Verdict
IEC 62443 secures industrial control systems via zones, security levels, and certifications for OT resilience. ISO 22000 ensures food safety through HACCP, PRPs, and FSMS governance. Companies adopt them for compliance, risk reduction, supply chain trust, and market access.

IEC 62443 Details
What It Is
IEC 62443 is the international consensus-based series of standards for securing Industrial Automation and Control Systems (IACS). It provides a comprehensive, risk-based framework spanning governance, risk assessment, system architecture, and component requirements tailored to OT environments with unique constraints like safety and availability.
Key Components
- Four groupings: General (-1), Policies/Procedures (-2), System (-3), Components (-4)
- Seven Foundational Requirements (FR1-7) like identification, integrity, data flow
- Security Levels (SL 0-4) with SL-T (target), SL-C (capability), SL-A (achieved)
- Zone/conduit model for segmentation; ISASecure certifications (SDLA, CSA, SSA)
Why Organizations Use It
- Mitigates OT cyber risks to safety, production, environment
- Enables supplier qualification, procurement specs, insurance benefits
- Builds stakeholder trust via certifications; supports regulatory baselines
- Facilitates IIoT/digital transformation securely
Implementation Overview
- Phased: governance (2-1), risk assessment (3-2), controls (3-3/4-2), certification
- Applies to asset owners, integrators, suppliers in critical sectors globally
- Multi-year program with maturity levels (ML1-4), audits
ISO 22000 Details
What It Is
ISO 22000:2018 is the international standard for Food Safety Management Systems (FSMS). It provides a certifiable framework for organizations in the food chain to ensure safe products through systematic hazard control, integrating HACCP principles with management system discipline using a risk-based approach and High-Level Structure (HLS).
Key Components
- **Clauses 4-10Context, leadership, planning, support, operation, evaluation, improvement.
- Core elements: PRPs, hazard analysis, OPRPs/CCPs, traceability, communication, audits.
- Built on Codex HACCP and dual PDCA cycles (organizational and operational).
- Voluntary certification via accredited bodies.
Why Organizations Use It
- Meets regulatory/customer requirements; reduces recalls and risks.
- Enhances supply chain trust, market access (e.g., GFSI schemes).
- Drives efficiency, integration with ISO 9001/14001; builds resilience.
Implementation Overview
- Phased: gap analysis, PRPs, hazard plans, training, audits.
- Applies to all food chain actors; scalable by size.
- Certification: stage 1/2 audits, annual surveillance.
