AI Risk Register: Structure, Components & Continuous Model Risk Governance Framework
The step-by-step structural blueprint for engineering an Enterprise AI Risk Register aligned with ISO/IEC 42001:2023 and the NIST AI Risk Management Framework (AI RMF). Details column-by-column schemas for tracking model lineage, training data sensitivity, autonomous tool permissions, and residual risk approvals.
Interactive Technical Checklist (12 Verification Checkpoints)
-
[1. Asset Inventory] Assign unique Model ID, business owner, technical lead, and deployment environment (staging/prod) for every AI system.Mandate: ISO 42001 A.2.2
-
[1. Asset Inventory] Document algorithmic classification (e.g., fine-tuned LLaMA-3, proprietary regression, third-party OpenAI API).Mandate: Model Governance
-
[2. Data Lineage] Catalog training dataset sources, licensing rights, consent validation, and DPDP PII classifications.Mandate: DPDP Act §8(1)
-
[2. Data Lineage] Verify that personal data ingested into RAG vector databases is masked or tokenized.Mandate: Privacy Safeguards
-
[3. Inherent Risk] Evaluate inherent prompt injection risk (direct and indirect) based on user exposure and tool execution capabilities.Mandate: OWASP LLM01
-
[3. Inherent Risk] Assess potential business impact of model hallucination on financial calculations, medical advice, or legal contracts.Mandate: Model Reliability
-
[4. Controls] Document technical guardrail architecture (input sanitization, output filtering, system prompt protection).Mandate: ISO 42001 A.6.2
-
[4. Controls] Enforce strict rate-limiting and budget alerts per user/IP to mitigate Denial of Wallet attacks.Mandate: Cloud Financial Defense
-
[5. Residual Risk] Calculate residual risk score after technical controls; require formal sign-off from Chief AI Officer or CISO for high-risk models.Mandate: Executive Accountability
-
[6. Drift Monitoring] Deploy automated telemetry tracking perplexity, latency drift, and toxicity scores with automated alerting on thresholds.Mandate: MLOps Governance
-
[6. Drift Monitoring] Schedule mandatory bi-annual AI Red Teaming assessments simulating state-of-the-art jailbreaks and prompt injections.Mandate: Adversarial Testing
-
[7. Audit & Decommission] Establish model sunset and secure weight deletion protocol when models are deprecated or replaced.Mandate: Data Minimization
Deploying AI in enterprise environments without a structured risk register is a major regulatory liability. ISO/IEC 42001 and the EU AI Act mandate that organizations maintain an exhaustive, continuously updated register documenting model lineage, potential harms, and mitigation controls.
