Zero Trust Engineering — Cross-domain logical service dependency matrix

/02 About

Cross-domain integration engineering reference for cross-domain logical service dependency matrix, including policy, logical interfaces, recovery and assurance.

Purpose: Cross-domain logical service dependency matrix. Domain: Cross-domain integration. Family: governance. Scenario trigger: Map required security service dependency across trust domains. Input assurance: Service functions, owners, availability and calling contracts. Evaluation: Evaluate transitive dependencies and control-plane circularity. Governing policy: Logical security service dependency and outage isolation policy. Resource-side obligation: Publish reviewed provider-consumer dependency and contingency graph. Protected concern: Enterprise security service catalog. Logical interface: Service owner provider consumer function availability and alternate. Evidence: Dependency matrix criticality failover and review record. Failure: Circular dependency or unavailable single point of trust. Required recovery: Decouple control service and establish independent fallback. Architectural invariant: No security-critical service should depend on an unmodeled authority 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.
