🏭 IEC 62443-4-1 / 4-2

IEC 62443 industrial security

Secure development process and component security requirements for industrial automation and control systems.

Overview

IEC 62443 is the recognised cybersecurity framework for industrial automation and control systems (IACS), covering the product development process (4-1) and component requirements (4-2), plus system-level zoning and risk (3-2/3-3).

We provide component-level consulting and testing, helping industrial products establish a secure development lifecycle and reach their target security level (SL).

Scope of testing & assessment

4-1 secure development lifecycle (SDL) process and audit
4-2 foundational requirements (FR1–FR7) and security levels SL 1–4
Authentication, access control and use control
Data integrity, confidentiality and resource availability
Firmware review, vulnerability assessment and log audit
Gap analysis and implementation support

Why it matters

🏭

Production continuity

Downtime is costly; security is part of operational continuity.

🔒

Supply-chain requirement

More asset owners make 62443 a purchasing prerequisite.

🧱

Defence in depth

Security levels and zoning build verifiable protection.

Our service process

1
Scope confirmation
Clarify the product type, target markets and applicable clauses, and define the tests and documents needed.
2
Standard alignment
Map the product's current state to the standard's requirements and produce a gap analysis.
3
Assessment & testing
Run the test plan and process audit; add penetration testing and fuzzing where needed.
4
Evidence review
Consolidate results and evidence, map each item to a clause, and form an auditable record.
5
Report & roadmap
Deliver the report and improvement recommendations; for markets that require filing, help prepare the submission.

Typical deliverables

Gap analysis report and conformity matrix
Test plan, test records and evidence
Technical documentation and (where applicable) a draft declaration of conformity
Improvement recommendations and follow-up milestones
Submission checklist and assistance (for markets that require filing)
