Zero Trust Engineering — Caching, replicas and offline-access security

/02 About

Data and information protection engineering reference for caching, replicas and offline-access security, including policy, logical interfaces, recovery and assurance.

Purpose: Caching, replicas and offline-access security. Domain: Data and information protection. Family: resilience. Scenario trigger: Serve protected data from cache, replica or disconnected node. Input assurance: Local policy revision, data classification and authorization lease. Evaluation: Verify cached authorization freshness and copy exposure. Governing policy: Cache data handling, offline leases and replica consistency policy. Resource-side obligation: Provide bounded offline access or deny stale information. Protected concern: Distributed protected data copies. Logical interface: Replica ID data lineage access lease expiry and policy revision. Evidence: Copy lineage authorization lease and synchronization evidence. Failure: Expired grant, policy drift or uncontrolled cached plaintext. Required recovery: Invalidate copies and reconcile policy before renewed access. Architectural invariant: Cached copies cannot expand rights beyond bounded authorization leases 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.
