Zero Trust Engineering — Constrained and headless device security

/02 About

Devices and endpoints engineering reference for constrained and headless device security, including policy, logical interfaces, recovery and assurance.

Purpose: Constrained and headless device security. Domain: Devices and endpoints. Family: exchange. Scenario trigger: Identify constrained device requesting service. Input assurance: Manufacturer identity, firmware provenance and local trust evidence. Evaluation: Verify minimal authenticated device claims within resource limits. Governing policy: Headless device admission and credential bootstrap policy. Resource-side obligation: Provision constrained authorization and compartmentalized telemetry. Protected concern: Embedded device network and control function. Logical interface: Embedded device attestation handshake secure command authorization and expiry. Evidence: Bootstrap identity firmware integrity and limited access evidence. Failure: Unavailable secure storage or weak device attestation. Required recovery: Limit device commands and route through controlled gateway. Architectural invariant: Resource constraints cannot justify unauthenticated security-sensitive commands Adoption: replace reference roles with concrete owner-controlled services. Specify exact provider/consumer identities, schema fields and classifications, signal provenance and freshness, idempotency, authorization lifetime, timeout/retry limits, observation and tamper evidence. A denied or failed operation must not silently become a permitted one. Scope: original vendor-neutral, implementation-agnostic technical reference model. Illustrative logical components and behaviors are neither a deployed system nor evidence of regulatory compliance. Package identities remain stable within the package; cross-package semantic reconciliation requires separate explicit registry support.
