Security Guideline
IEC 62443 in practice: Securely integrating remote access into your system
What to expect:
- Classification of IEC 62443 across all levels – system, integration, and component
- Clear implementation guidance for IEC 62443-4-2 requirements
- Practical recommendations for the secure integration of remote access
- Assessment of achievable security levels in real-world operational contexts
- Architectural examples for secure OT networks (zones & conduits)
- Technical configuration guidelines for mbNET and mbNET.rokey
This guideline helps you systematically implement security concepts and document them in a way that is transparent to customers, auditors, and operators.
The IEC 62443 series of standards takes a holistic approach to industrial safety – from risk analysis and system design to requirements for individual components. However, a key challenge arises during implementation: How can specific devices be optimally integrated into a secure overall system?
Our Security Guideline provides a practical solution. It demonstrates how mbNET and mbNET.rokey can be deployed and configured as central communication components in an IEC 62443-compliant architecture – tailored to typical application scenarios in machines and systems.
You will find guidance on implementing system requirements (e.g., from IEC 62443-3-3) at the component level (IEC 62443-4-2).
