Zero Trust Engineering — Identity-to-application authorization integration

/02 About

Cross-domain integration engineering reference for identity-to-application authorization integration, including policy, logical interfaces, recovery and assurance.

Purpose: Identity-to-application authorization integration. Domain: Cross-domain integration. Family: decision. Scenario trigger: Authorize application request by principal and service claims. Input assurance: User identity, workload identity, token audience and operation. Evaluation: Evaluate delegated application scope and resource-specific rules. Governing policy: Application identity-to-permission propagation policy. Resource-side obligation: Enforce fine-grained API or session grant at protected operation. Protected concern: Enterprise business application API. Logical interface: Subject service identity audience scope operation decision and expiry. Evidence: Identity propagation chain app authorization and response evidence. Failure: Forged delegated actor or overbroad application token. Required recovery: Deny operation and request trusted end-user and workload context. Architectural invariant: Service authentication cannot turn broad delegated claims into application privilege 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.
