Zero Trust Engineering — Role, attribute and relationship-based authorization

/02 About

Identity and access engineering reference for role, attribute and relationship-based authorization, including policy, logical interfaces, recovery and assurance.

Purpose: Role, attribute and relationship-based authorization. Domain: Identity and access. Family: decision. Scenario trigger: Request access with role, attribute and relationship evidence. Input assurance: Role membership, resource tags, relationships and environment. Evaluation: Evaluate fine-grained policy combining supported models. Governing policy: Least privilege, policy precedence and deny overrides. Resource-side obligation: Enforce scoped action and object authorization. Protected concern: Protected business resource. Logical interface: Subject action object relationship claims policy response and conditions. Evidence: Authorization attributes policy version and obligations. Failure: Ambiguous policy conflict or attribute spoofing. Required recovery: Deny unsafe action and request policy reconciliation. Architectural invariant: Authorization applies to subject-action-object-context and must not inherit broad implicit permission 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.
