Zero Trust Engineering — Hardware and software integrity measurement

/02 About

Devices and endpoints engineering reference for hardware and software integrity measurement, including policy, logical interfaces, recovery and assurance.

Purpose: Hardware and software integrity measurement. Domain: Devices and endpoints. Family: assurance. Scenario trigger: Measure boot and runtime integrity. Input assurance: Signed boot measurements, software manifest and trusted root. Evaluation: Compare measured state against approved integrity baselines. Governing policy: Trusted boot, configuration and firmware acceptance policy. Resource-side obligation: Publish integrity assessment with bounded freshness. Protected concern: Sensitive endpoint execution environment. Logical interface: Measured boot event firmware hash approved baseline and time. Evidence: Integrity measurement manifest and decision evidence. Failure: Tampered firmware or untrusted measurement origin. Required recovery: Limit access and invoke measured-state repair. Architectural invariant: Claims of software integrity require authenticated measurements and approved baselines 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.
