Zero Trust Engineering — Unmanaged and BYOD access containment
securityv1/01 Views
/02 About
Devices and endpoints engineering reference for unmanaged and byod access containment, including policy, logical interfaces, recovery and assurance.
Purpose: Unmanaged and BYOD access containment. Domain: Devices and endpoints. Family: decision. Scenario trigger: Receive access request from unmanaged endpoint. Input assurance: Ownership uncertainty, browser isolation and requested information class. Evaluation: Assess unmanaged-device risk and permissible interaction mode. Governing policy: Unmanaged access scope, persistence and download restrictions. Resource-side obligation: Provide restricted ephemeral access or explicit denial. Protected concern: Enterprise information delivery interface. Logical interface: Unmanaged client trust assumption session controls and data handling. Evidence: Unmanaged access policy decision and content handling events. Failure: Unknown device posture or attempt to export restricted data. Required recovery: Block persistent transfer and require managed trust path. Architectural invariant: Unmanaged devices must not gain cached credentials or unrestricted sensitive data 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.
