Zero Trust Engineering — Policy decision, enforcement and obligation contract
securityv1/01 Views
/02 About
Cross-domain integration engineering reference for policy decision, enforcement and obligation contract, including policy, logical interfaces, recovery and assurance.
Purpose: Policy decision, enforcement and obligation contract. Domain: Cross-domain integration. Family: exchange. Scenario trigger: Exchange authorization decision with resource-side enforcement. Input assurance: Subject resource action policy hash and applicable attributes. Evaluation: Validate decision semantics, obligations and issuance authority. Governing policy: Decision contract version, permit conditions and error behavior policy. Resource-side obligation: Apply mandatory obligations and refuse unsupported permit. Protected concern: Authorized resource operation boundary. Logical interface: Decision ID version issuer allow deny step-up revoke obligations and expiry. Evidence: Decision and obligation acknowledgement implementation record. Failure: Unknown obligation, signature failure or incompatible decision schema. Required recovery: Reject decision and request trusted policy clarification. Architectural invariant: A permit with unenforceable obligations is not executable 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.
