ISO 42001 – Clause 8.3 – AI Risk Treatment

---

Turning AI Risk Assessments into Action

After identifying and assessing AI risks under Clause 8.2, Clause 8.3 – AI Risk Treatment is where the rubber meets the road. This clause mandates that organizations move from awareness to action by implementing controls to manage, mitigate, or eliminate those risks.

Risk treatment is the practical application of your AI governance strategy, ensuring that your AI systems operate safely, fairly, and in a compliant manner.

✅ What Does Clause 8.3 Require?

Your organization must:

• Select appropriate risk treatment options — these may include eliminating the risk, mitigating it with controls, transferring it (e.g., via insurance or contracts), or formally accepting it if it falls within your defined risk appetite.
• Implement the chosen controls — apply technical, procedural, or organizational measures to address AI-specific risks like bias, opacity, or performance degradation.
• Document the treatment plan — create a clear record of responsibilities, timelines, and the criteria for judging the effectiveness of each control.
• Evaluate residual risk — assess any remaining risk after treatment to ensure it is acceptable and approved by relevant decision-makers.
• Integrate treatment into operational processes — so that risk management is an ongoing, living part of the AI lifecycle, not a one-off exercise.

🧠 Why Is This Crucial for AI Systems?

AI introduces risks that can evolve over time — a model that is safe today may become biased or inaccurate tomorrow. Without a dynamic treatment plan, your AI risk assessment becomes a static document rather than a living control mechanism.

Effective risk treatment ensures that:

• Bias is actively reduced, not just detected.
• Explainability gaps are addressed with interpretable AI tools or human oversight.
• Model performance is safeguarded against drift or data poisoning.
• Ethical principles are enforced through tangible actions, not just stated in policies.

🛠️ Implementation Strategy for AI Risk Treatment

Step	Actions
Define treatment criteria	Set clear thresholds for when a risk must be treated versus when it can be accepted.
Match risks to controls	Link each identified AI risk to specific mitigation measures (e.g., bias mitigation algorithms, human review).
Assign accountability	Assign owners for each risk treatment action to ensure follow-through.
Verify effectiveness	Test whether controls work as intended and measure their impact on reducing risk.
Review periodically	Align risk treatment reviews with AI model retraining cycles or other significant lifecycle updates.

📝 Example AI Risk Treatment Actions

Risk	Treatment Option	Example Control
Algorithmic Bias	Mitigation	Introduce diverse training data and apply bias correction models.
Explainability Gap	Mitigation	Use SHAP/LIME explainability tools and human-in-the-loop reviews.
Data Drift	Mitigation	Implement automated model monitoring with drift detection alerts.
Malicious Misuse	Mitigation/Avoidance	Restrict access via strong authentication and monitor usage logs.

Clause 8.3 is about closing the loop — ensuring that risks don’t just sit in an assessment report but are actively managed through targeted, effective, and documented actions.
