Zero Trust Engineering — DNS and name-resolution security

/02 About

Networks and environments engineering reference for dns and name-resolution security, including policy, logical interfaces, recovery and assurance.

Purpose: DNS and name-resolution security. Domain: Networks and environments. Family: exchange. Scenario trigger: Resolve protected service identity through name service. Input assurance: Authenticated namespace ownership, DNS policy and resolver provenance. Evaluation: Validate resolution authenticity and protected destination binding. Governing policy: Trusted name resolution, anti-spoofing and response policy. Resource-side obligation: Return policy-constrained service location mapping. Protected concern: Enterprise service name-resolution plane. Logical interface: Namespace requested identity signed response expiry and binding. Evidence: Resolver request answer provenance cache expiry and anomaly log. Failure: Poisoned answer, stale record or unauthorized namespace. Required recovery: Invalidate unsafe resolution and require trusted resolver. Architectural invariant: Untrusted name answers must not redirect protected service credentials 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.
