Supply chain security

I have been writing intermittently about it, and the global supply chain shortage has been a blessing in disguise – countries have started realising its importance and delinking the supply chains to concentrate in specific locations. We are moving towards a “knowledge-based economy,” and someone should make connections between these events and the earlier onset of the power-looms (even if the initial designs were stolen and brought to the US).

Why It’s So Difficult — And Costly — To Secure Chips

Until very recently, semiconductor security was viewed more as a theoretical threat than a real one. Governments certainly worried about adversaries taking control of secure systems through back doors in hardware, either through third-party IP or unknowns in the global supply chain, but the rest of the chip industry generally paid little heed apart from the ability to boot securely and to authenticate firmware. But as advanced electronics are deployed in cars, robots, drones, medical devices, as well as in a variety of server applications, robust hardware security is becoming a requirement. It no longer can be brushed aside as a ‘nice-to-have’ feature because IC breaches can affect safety, jeopardize critical data, and sideline businesses until the damage is assessed and the threat resolved.

Security must be built from ground up – it is not a matter of checking the boxes, but a cultural practice.
