Zero Trust Engineering — Enterprise trust-boundary and threat propagation model
securityv1/01 Views
/02 About
Cross-domain integration engineering reference for enterprise trust-boundary and threat propagation model, including policy, logical interfaces, recovery and assurance.
Purpose: Enterprise trust-boundary and threat propagation model. Domain: Cross-domain integration. Family: assurance. Scenario trigger: Analyze adversarial movement across enterprise trust boundaries. Input assurance: Trust domains, assets, entry points and attack preconditions. Evaluation: Evaluate feasible threat propagation and available enforcement barriers. Governing policy: Enterprise threat boundary, risk classification and control policy. Resource-side obligation: Enforce verified boundaries and prioritize vulnerable pathways. Protected concern: Enterprise distributed resource trust graph. Logical interface: Threat source boundary target identity precondition and control outcome. Evidence: Attack path preconditions control gaps and mitigation evidence. Failure: Unmodeled credential reuse crosses multiple trust domains. Required recovery: Contain affected identities and close uncontrolled boundary. Architectural invariant: Every trust crossing requires independently justified authorization 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.
