Design Poise covers IoT and OT device security across the device, the network, and the lifecycle — threat modeling, cryptographic identity, OTA security, OT segmentation, and lifecycle automation — aligned to NIST IR 8259 and the realities of how devices actually live and die in the field.
STRIDE and PASTA-based threat modeling for embedded and connected devices — with the threat boundary, attacker capability, and asset inventory documented before architecture decisions are made.
Secure boot chain design, cryptographic device identity (TPM, secure element, eFuse), and remote attestation — so the device can prove who it is before it is trusted on the network.
Signed firmware, secure update channels, anti-rollback protection, and recovery design — the OTA story that does not become the breach story when a key leaks.
IT/OT segmentation, ICS protocol security (Modbus, OPC UA, DNP3), edge gateway hardening, and network monitoring — designed for the constraints OT environments actually have.
Provisioning, key rotation, certificate management, decommissioning, and secure disposal — with the lifecycle automated where possible and audited where it matters.
Four phases that take an IoT device security engagement from threat modeling through architecture and implementation to validation — with senior security engineers on the firmware, the hardware, and the back-end, and validation tied to the original threat model.
Device threat model built against the use case, the deployment environment, and the realistic attacker — not the textbook attacker. Boundaries, assets, and risks documented before any architecture work.
Device security architecture designed across boot, identity, communication, OTA, and lifecycle — with cryptographic primitives and key hierarchies documented before silicon or firmware decisions lock in.
Security controls implemented in firmware, hardware, and back-end — with code review, key ceremony documentation, and integration testing on actual hardware, not just on the simulator.
Pen testing, fuzzing, and field validation against the threat model — with findings tied to architecture decisions and remediation prioritised against actual device risk, not generic vulnerability scores.
