Zero Trust Engineering — East-west service communication security

/02 About

Networks and environments engineering reference for east-west service communication security, including policy, logical interfaces, recovery and assurance.

Purpose: East-west service communication security. Domain: Networks and environments. Family: decision. Scenario trigger: Request internal service-to-service connection. Input assurance: Mutual workload identity, service purpose and local trust context. Evaluation: Evaluate bilateral service invocation authorization. Governing policy: Internal service identity and east-west least-privilege policy. Resource-side obligation: Permit authenticated service request within bounded purpose. Protected concern: Distributed business service mesh. Logical interface: Source service destination service operation audience and expiration. Evidence: Service peer identity invocation and enforcement evidence. Failure: Unauthenticated lateral call or mismatched audience. Required recovery: Block call and notify service risk owner. Architectural invariant: Internal address proximity does not remove authentication requirements 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.
