Zero Trust Engineering — Network security at constrained edge sites

/02 About

Networks and environments engineering reference for network security at constrained edge sites, including policy, logical interfaces, recovery and assurance.

Purpose: Network security at constrained edge sites. Domain: Networks and environments. Family: resilience. Scenario trigger: Request protected resource access at remote or disrupted site. Input assurance: Local policy revision, endpoint assurance and connectivity state. Evaluation: Evaluate bounded offline authorization and sync risk. Governing policy: Edge site policy freshness and fail-secure operation policy. Resource-side obligation: Restrict essential flows and defer high-risk actions. Protected concern: Disconnected edge application network. Logical interface: Edge policy revision offline decision quota expiration and reconciliation. Evidence: Offline policy use, deferred events and resynchronization record. Failure: WAN partition, expired policy or unverifiable endpoint. Required recovery: Contain affected workflows and reconcile authoritative state after recovery. Architectural invariant: Disconnected operation must preserve preauthorized scope and expiry 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.
