Example scenario
Example scenario: A control system upgrade project required IEC 62443 alignment, but the contract only provided high-level cybersecurity requirements and no clear method for demonstrating compliance.

The problem
IEC 62443 is often referenced in contracts, but projects can struggle to translate it into practical engineering deliverables, verification evidence, and clear assumptions.
What we do
Activities
- define the system under consideration
- identify zones and conduits
- support SL-T discussions
- review supplier cybersecurity requirements
- produce requirements and evidence matrices
- support risk assessment workshops
- generate project cybersecurity assurance documentation
Deliverables
- SuC definition
- zones and conduits model
- IEC 62443 gap assessment
- SL-T review support
- requirements and evidence matrix
- cybersecurity requirements traceability
- verification plan
Example scenario
Meridian-style response
Meridian-style response: The project scope was broken down into systems, interfaces, zones, and conduits. An evidence matrix and assessment method were developed to show how each requirement would be addressed through design, configuration, testing, or operational controls.
