Zero Trust Engineering — Policy information point architecture

/02 About

Identity and access engineering reference for policy information point architecture, including policy, logical interfaces, recovery and assurance.

Purpose: Policy information point architecture. Domain: Identity and access. Family: exchange. Scenario trigger: Query authoritative attribute information sources. Input assurance: Attribute issuer identity, provenance, freshness and version. Evaluation: Validate policy information authenticity and consistency. Governing policy: Attribute resolution, caching and source-of-truth policy. Resource-side obligation: Provide trusted policy evaluation context. Protected concern: Policy evaluation information exchange. Logical interface: Context attribute query source version expiry provenance and confidence. Evidence: Attribute query provenance cache and response evidence. Failure: Unavailable authoritative source or stale cached value. Required recovery: Return indeterminate context and restrict affected decisions. Architectural invariant: Policy inputs require explicit trust, freshness and unavailable-source semantics 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.
