IEC 62443 Consulting for Industrial Automation
We help manufacturers of industrial controllers, automation components and OT-connected embedded products apply ISA/IEC 62443 in product development. The work defines the applicable parts and target security level, evaluates development practice against IEC 62443-4-1 and product capabilities against IEC 62443-4-2, and prepares the evidence an independent assessment needs, producing a prioritized gap register and implementation plan.
- Scope
- Agree the product, versions, interfaces and the parts of the series that apply.
- Risk
- Assess threats and consequences to set the target security level.
- Requirements
- Map IEC 62443-4-1 practices and IEC 62443-4-2 requirements to the design.
- Evidence
- Verify the implementation and record traceable results for assessment.
Scope
Scope and target security level definition
Gap assessment against IEC 62443-4-1 and 4-2
Zones and conduits for system-level work
Starting information
Product description, intended deployment, interfaces, current development process records and any customer security requirements.
Applicable framework
The ISA/IEC 62443 series is the reference. Requirements are selected for the role performed, the object assessed and the agreed editions. Certification schemes, CRA and NIS2 obligations are assessed separately; IEC 62443 work is not presented as automatic regulatory conformity.
Product supplier
IEC 62443-4-1 for the secure development lifecycle and IEC 62443-4-2 for component requirements, evaluated against the capability level the product claims.
System integrator
IEC 62443-3-2 risk assessment with zones, conduits and target security levels, and IEC 62443-3-3 system requirements.
IEC 62443 for Industrial Automation
Engineering secure products and control systems
A practical engineering reference to the ISA/IEC 62443 series for industrial automation and control systems (IACS). It shows how responsibilities, risk assessment, security levels and lifecycle evidence connect, following an illustrative packaging line from a remote-maintenance risk through to handover.
What you will learn
- How protection responsibilities divide between asset owners, integrators, product suppliers and service providers, and which parts of the series apply to each role.
- How a system risk assessment under IEC 62443-3-2 turns process consequences into zones, conduits, target security levels and a cybersecurity requirements specification.
- How to produce traceable evidence across secure development (IEC 62443-4-1), component capabilities (IEC 62443-4-2), verification, patching and recovery.
Intended audience
Automation manufacturers, machine builders and system integrators. Also relevant to asset owners and operators who specify, accept and maintain these systems.
An engineering overview, not a substitute for the applicable standards or a conformance assessment.
