Zero Trust Engineering — Business criticality and protect-surface selection

/02 About

Governance and assurance engineering reference for business criticality and protect-surface selection, including policy, logical interfaces, recovery and assurance.

Purpose: Business criticality and protect-surface selection. Domain: Governance and assurance. Family: governance. Scenario trigger: Determine which assets merit protected-resource priority. Input assurance: Business impact, critical dependencies and sensitive information. Evaluation: Rank resource protect surfaces by impact and credible threat. Governing policy: Business criticality, risk classification and prioritization policy. Resource-side obligation: Publish approved bounded protect-surface inventory. Protected concern: High-value enterprise resources. Logical interface: Protected resource impact tier sensitivity dependency and rationale. Evidence: Protected surface selection rationale dependencies and owner approval. Failure: Unknown dependency or critical data omitted from assessment. Required recovery: Expand impact study and constrain affected unclassified resources. Architectural invariant: Resource priority must be informed by business impact and data sensitivity 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.
