Zero Trust Engineering — Microsegmentation policy and enforcement

/02 About

Networks and environments engineering reference for microsegmentation policy and enforcement, including policy, logical interfaces, recovery and assurance.

Purpose: Microsegmentation policy and enforcement. Domain: Networks and environments. Family: decision. Scenario trigger: Evaluate an east-west workload connection. Input assurance: Workload identity, service attributes and directed flow policy. Evaluation: Calculate least-privilege allow-list decision for both endpoints. Governing policy: Workload segment membership and bilateral authorization policy. Resource-side obligation: Enforce host or service-level isolation and connection scope. Protected concern: East-west application network. Logical interface: Workload pair traffic intent service tuple decision and enforcement revision. Evidence: Segment policy revision accepted flow and enforcement evidence. Failure: Workload lateral movement or mismatched segment policy. Required recovery: Terminate unauthorized flow and reconcile enforcement drift. Architectural invariant: Microsegmentation must bind policy to workload identities beyond IP address 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.
