Hardware Security Fails in Meetings, Not in Exploits

In over a decade of analyzing compromised embedded hardware, one constant truth stands out: Hardware exploits do not originate in brilliant attacker laboratories. They originate in engineering compromise meetings.

Where Security Decisions Are Actually Made:

1. The Debug Interface: "Let's leave SWD/JTAG test points accessible on the PCB in case factory testing has issues—we'll disable it in firmware later." (Spoiler: firmware disabling was forgotten).
2. The Cost Reduction: "Using a secure element adds zsh.40 per unit. Let's store the AES master key in external SPI flash instead."
3. The Schedule Rush: "Enabling hardware crypto acceleration delays tape-out by 3 weeks. Let's ship with standard boot and update it over-the-air."

The Board-Level Lesson

Hardware security is not a technical problem; it is a cross-functional governance discipline. Security must be represented at design time when silicon decisions are locked in permanent silicon.
