Zero Trust Engineering — Risk scoring and signal-confidence evaluation
securityv1/01 Views
/02 About
Visibility and analytics engineering reference for risk scoring and signal-confidence evaluation, including policy, logical interfaces, recovery and assurance.
Purpose: Risk scoring and signal-confidence evaluation. Domain: Visibility and analytics. Family: decision. Scenario trigger: Combine contextual risk signals for authorization or response. Input assurance: Identity device network workload and data risk inputs. Evaluation: Calculate explainable bounded risk with signal uncertainty. Governing policy: Risk calculation threshold model and policy precedence. Resource-side obligation: Publish scored signal with explicit confidence and freshness. Protected concern: Contextual policy and security orchestration service. Logical interface: Risk factors source confidence model version bounds and timestamp. Evidence: Risk score factor lineage uncertainty and policy influence. Failure: Missing signals, adversarial manipulation or expired assessment. Required recovery: Mark assessment indeterminate and invoke conservative decision. Architectural invariant: Probabilistic risk scoring must not bypass explicit policy constraints 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.
