Use Case: IoT Device Security and Component Verification for Aircraft Manufacturing

Actor Profile

Daniel Foster, Aircraft Manufacturing Engineer

Oversees aircraft manufacturing where safety depends on secure IoT operations and supply chain verification. Ensures every component is authentic, every process is verified, and every device is tamper-free.

Business Context

Aircraft manufacturing requires stringent safety standards and regulatory compliance. IoT devices used for production monitoring collect critical data that must be protected against tampering and unauthorized access. Global supply chains create counterfeiting risks and challenges in authenticity verification. Regulatory audits demand comprehensive documentation and traceability. Cybersecurity threats to connected devices pose significant safety risks.

Challenge Statement

Daniel must secure IoT devices monitoring critical processes while ensuring supply chain transparency and regulatory compliance. IoT devices lack inherent security, allowing unauthorized access and data tampering that compromises integrity and safety assurance. Counterfeit or substandard components create safety risks. Manual compliance documentation is time-consuming and error-prone. Component traceability remains fragmented and unreliable.
