Securing the Supply Chain

Supply-chain security is usually told as two separate industries. Silicon on one side. Repositories on the other. The incidents happen in the seam: firmware, build systems, signed artifacts, the vendor who ships a library nobody owns.

This essay walks that seam without the costume of a threat report. It is a positioning piece for buyers who are tired of being handed a bill of materials and told that the paperwork is the control.

The through-line is operational. If you cannot explain the path from hardware root to running workload, you do not have a supply chain. You have a hope.

A bill of materials is not a control. It is a map. Someone still has to walk it.
