Zero Trust Engineering — Enterprise network trust-boundary model

/02 About

Networks and environments engineering reference for enterprise network trust-boundary model, including policy, logical interfaces, recovery and assurance.

Purpose: Enterprise network trust-boundary model. Domain: Networks and environments. Family: governance. Scenario trigger: Request definition or revision of network trust domain. Input assurance: Network zones, administrative authority and resource sensitivity. Evaluation: Assess permitted cross-zone access and lateral risk. Governing policy: Trust-boundary ownership and crossing requirement policy. Resource-side obligation: Establish explicit authorization gates at trust boundaries. Protected concern: Segmented enterprise network topology. Logical interface: Trust boundary identity origin destination crossing condition and approval. Evidence: Boundary entry inventory crossings and policy mapping. Failure: Ambiguous trust boundary or unmediated transit path. Required recovery: Deny unreviewed cross-boundary flows and revise topology. Architectural invariant: Network location is context, not proof of principal or resource trust 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.
