Challenge
Assessment and response
Risks identified
- unclear supplier access responsibilities
- weak interface documentation
- insufficient FAT cybersecurity evidence
- broad network connectivity assumptions
Meridian approach
- reviewed supplier design submissions
- identified package interfaces and access routes
- commented on firewall and account requirements
- defined cybersecurity verification checks for acceptance
Deliverables
- supplier design review comments
- interface register
- FAT cybersecurity checklist
- close-out tracker
- acceptance evidence review
Outcome
The project gained clearer integration requirements and a practical evidence set for package acceptance without exposing live control systems unnecessarily.
