Zero Trust Engineering — Identity authority and trust-domain federation

/02 About

Identity and access engineering reference for identity authority and trust-domain federation, including policy, logical interfaces, recovery and assurance.

Purpose: Identity authority and trust-domain federation. Domain: Identity and access. Family: exchange. Scenario trigger: Receive identity assertion from another trust domain. Input assurance: Issuer metadata, verification keys and attribute provenance. Evaluation: Verify federation issuer, audience and attribute trust. Governing policy: Federation acceptance, audience and subject-mapping policy. Resource-side obligation: Bind foreign assertion to locally authorized principal. Protected concern: Cross-domain relying application. Logical interface: Issuer audience signature expiry subject mapping and trust assurance. Evidence: Federation assertion validation and mapping events. Failure: Unknown issuer, assertion replay or trust-anchor withdrawal. Required recovery: Reject external assertion and request trusted reauthentication. Architectural invariant: Cross-domain authentication never grants resource authorization on its own 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.
