Securing Halden's connected devices below the operating system on the hardware trust board, drawn as a circuit board of eight domains — boot, firmware, root of trust, supply chain, interfaces, storage, runtime and recovery; a verified boot chain where a fused boot ROM verifies each bootloader in turn and the OS is measured into the TPM; per-device keys moved from one shared key to 48,000 unique ones; a downgrade to an old firmware version rejected by the anti-rollback counter; and a firmware SBOM for all 34 products.

Firmware & Hardware Security — The Hardware Trust Board

A hands-on mid-level course that secures the layer below the operating system. Work the hardware trust board - eight domains: Boot, Firmware, Root of Trust, Supply Chain, Interfaces, Storage, Runtime, and Recovery - building verified boot, firmware update integrity, and hardware-backed trust so an attacker below the OS cannot own the device. Strictly defensive. Four hands-on activities in every lesson.
