Engineering data is the technical information used to design, build, test, and certify hardware. It includes drawings, CAD models, material lists, tolerances, wiring diagrams, test procedures, and specifications. In sectors like aerospace, this data is as valuable as the finished product because it defines how the product must be made and how it will perform.
From a cyber-security perspective, engineering data is a high-value target. If attackers steal, alter, or delete it, they can expose intellectual property, disrupt manufacturing, or introduce defects that are hard to detect until later testing or deployment. Defenders protect it with access control, encryption, version control, logging, and strict supplier segregation. In real operations, engineering data often moves between design teams, manufacturers, certifiers, and partners, so secure handling and identity management are critical at every transfer point.
