Zero Trust Engineering — Policy decision and administration architecture

/02 About

Identity and access engineering reference for policy decision and administration architecture, including policy, logical interfaces, recovery and assurance.

Purpose: Policy decision and administration architecture. Domain: Identity and access. Family: decision. Scenario trigger: Submit fully scoped authorization request. Input assurance: Principal, resource, action and environment assertions. Evaluation: Compute deterministic policy decision and obligations. Governing policy: Approved policy bundle, precedence and consistency rules. Resource-side obligation: Administer bounded permit, deny, step-up or revocation. Protected concern: Resource access enforcement point. Logical interface: Authorization request decision obligation policy revision and transaction identifier. Evidence: Decision correlation policy hash and administration audit. Failure: Conflicting policy versions or decision administration failure. Required recovery: Withhold authorization and reconcile policy activation. Architectural invariant: A permit without an enforceable obligation contract is not usable authorization 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.
