4.1 Clause 6.1 Risks, Opportunities & AI Risk Assessment
Key Takeaways
- Clause 6.1.1 requires planning actions for risks and opportunities using context (4.1) and interested-party needs (4.2), so the AIMS can achieve intended outcomes, prevent undesired effects, and continually improve.
- Clause 6.1.2 requires an AI-specific risk assessment process with defined criteria, consistent repeatable results, identification of AI risks across the lifecycle, and documented information of the assessment.
- Clause 6.1.3 requires risk treatment options, necessary controls, comparison with Annex A, a Statement of Applicability, and formal acceptance of residual AI risk by risk owners.
- ISO/IEC 23894 provides AI risk-management guidance that auditors use as a reference lens; ISO/IEC 42001 is the certifiable requirements standard—do not treat 23894 as the audit criteria unless agreed.
- A common major nonconformity is a generic enterprise or IT risk process that never addresses AI-specific failure modes such as model drift, bias, opacity, prompt injection, or data poisoning.
4.1 Clause 6.1 Risks, Opportunities & AI Risk Assessment
Auditor focus: Clause 6.1 answers: How does the organization identify AI risks and opportunities? Are criteria and methods AI-specific and repeatable? Is treatment planned, controls justified against Annex A, and residual risk accepted by named owners? If the risk process is only generic ERM/IT security language, findings escalate quickly.
Clause 6 is the Plan phase after context (4) and leadership/policy (5). For lead auditors, 6.1 is a high-yield trail: methodology, criteria, registers, treatment plans, Statement of Applicability (SoA), and residual-risk acceptance records.
6.1.1 General — Risks and Opportunities Planning
Under 6.1.1, the organization shall consider issues (4.1) and requirements of interested parties (4.2) and determine the risks and opportunities that need to be addressed to:
- Give assurance that the AIMS can achieve its intended outcomes.
- Prevent, or reduce, undesired effects.
- Achieve continual improvement.
The organization shall plan: (a) actions to address these risks and opportunities; and (b) how to integrate and implement the actions into AIMS processes, and how to evaluate the effectiveness of those actions.
Auditor interpretation: Opportunities are not optional cheerleading (e.g., maturity gains, fewer incidents, safer high-value deployments). Auditors check that opportunities are identified and acted on—not only threats.
| 6.1.1 element | What “good” looks like | Weak signal |
|---|---|---|
| Link to 4.1/4.2 | Context issues and interested-party requirements map into risk/opportunity entries | Risk register ignores regulatory AI duties and stakeholder harm themes |
| Intended outcomes | Outcomes tied to AI policy (trustworthy, fair, secure AI management) | Outcomes restated as “pass certification” only |
| Integration | Actions embedded in lifecycle, procurement, monitoring, and change processes | Standalone risk spreadsheet with no process owners |
| Effectiveness evaluation | KPIs, residual risk trends, treatment closure metrics | “We re-rate risks annually” with no evaluation method |
6.1.2 AI Risk Assessment
Clause 6.1.2 requires the organization to define and apply an AI risk assessment process that:
- Establishes and maintains AI risk criteria, including criteria for performing assessments and risk acceptance criteria.
- Ensures that repeated assessments produce consistent, valid, and comparable results.
- Identifies AI risks associated with the loss of confidentiality, integrity, availability, and—critically for AI—properties such as safety, fairness, transparency, explainability, and accountability across the AI system lifecycle.
- Analyses AI risks (consequences and likelihood) and evaluates them against the defined criteria to prioritize treatment.
Documented information of the AI risk assessment process and results shall be retained.
AI-specific criteria (what auditors test)
Generic ERM or ISO 27001-style matrices often fail 6.1.2 when they omit AI impact dimensions (discrimination, unsafe automation, opacity, data leakage, model theft). Auditors ask:
- Who approved the risk acceptance criteria, and are they consistent with the AI policy and risk appetite?
- How is likelihood estimated for probabilistic systems (historical incident rates, red-team findings, drift metrics, vendor failure rates)?
- How is impact scored for individuals and society—not only financial loss to the organization? (Impact assessment under 6.1.4 feeds this loop; see next section.)
- Is the process applied at defined triggers (new AI system, major retrain, new data source, new deployment context, third-party model swap)?
Relationship to ISO/IEC 23894
ISO/IEC 23894 (Artificial intelligence — Guidance on risk management) offers AI-oriented guidance on ISO 31000 principles. Auditors use it as a good-practice reference, not default audit criteria. Conformity is judged against ISO/IEC 42001 Clause 6.1. Do not raise an NC only for missing a 23894 citation—raise it when AI risk process substance fails 6.1.2.
Unique AI risk characteristics to expect in the methodology
| AI characteristic | Risk implication | Sample evidence |
|---|---|---|
| Non-deterministic outputs | Same input can yield different results; hard failure modes | Evaluation reports, confidence thresholds, human-in-the-loop rules |
| Opacity / limited explainability | Hard to detect latent failure before harm | Explainability strategy, model cards, decision-log samples |
| Data dependency | Bias, poisoning, quality drift | Data quality criteria, lineage, poisoning controls |
| Model / concept drift | Performance degrades after deployment | Monitoring dashboards, retrain triggers |
| Adversarial / novel attacks | Prompt injection, evasion, inversion, extraction | Threat models, red-team reports, API abuse controls |
6.1.3 AI Risk Treatment and Statement of Applicability Linkage
After assessment, 6.1.3 requires an AI risk treatment process that:
- Selects appropriate risk treatment options (typically avoid, mitigate/reduce, share/transfer, accept/retain—terminology may vary, substance matters).
- Determines all controls necessary to implement the chosen options.
- Compares the controls determined with those in Annex A and verifies that no necessary Annex A control has been omitted.
- Produces a Statement of Applicability that contains the necessary controls, justification for inclusions and exclusions, and whether the controls are implemented.
- Formulates an AI risk treatment plan.
- Obtains risk owners’ approval of the treatment plan and acceptance of residual AI risks.
SoA linkage: The SoA bridges 6.1 planning to Annex A. Auditors sample high risks, trace treatments to Annex A references, verify include/exclude justifications, check residual-risk acceptance against criteria, and confirm treatment owners, dates, and effectiveness checks.
Auditor Evidence Pack for Clause 6.1
| Evidence type | What to sample | Red flags |
|---|---|---|
| Risk methodology | Procedure/SOP defining criteria, scales, roles, frequency, triggers | “Follow ISO 31000” with no AI criteria |
| Risk register samples | 5–10 AI systems/use cases across risk tiers | Only cyber risks; no fairness/safety/transparency entries |
| Assessment records | Completed worksheets, workshops, scoring rationale | Identical scores for dissimilar systems |
| Treatment plan | Actions, owners, status, control mapping | Treatment = “monitor” with no control design |
| SoA | All Annex A controls listed with include/exclude + status | Mass exclusions “not relevant to us” without justification |
| Residual risk acceptance | Named owner, date, criteria reference | Acceptance by junior staff for high residual risk |
Scenario: Generic ERM failure (common NC)
Observation: The auditee presents a corporate risk register covering “IT systems” with CIA triad scores. AI systems appear as “applications.” There is no AI risk criteria document. Bias testing is described in a data-science wiki but not linked to risk evaluation or SoA. Residual “AI model risk” is accepted by an IT operations manager without defined acceptance criteria.
Audit reasoning: This commonly supports a nonconformity against 6.1.2 and/or 6.1.3: the process is not an AI risk assessment process (criteria and identification of AI-specific risks missing), and residual acceptance lacks defined criteria and appropriate ownership. A secondary trail often finds SoA justifications disconnected from any AI risk analysis.
Stage 1 vs Stage 2 emphasis
Stage 1 checks methodology, criteria, and SoA structure. Stage 2 samples real AI systems to verify assessments, treatments, residual-risk acceptance, and feed-through into objectives and management review.
During a Stage 2 audit, the auditee’s only risk process is a corporate ERM matrix scoring financial and operational IT risks. AI systems are listed as applications with confidentiality/integrity/availability scores only. Which Clause 6.1 requirement is most clearly failing?
What is the primary role of comparing determined controls with Annex A under Clause 6.1.3?
How should an ISO/IEC 42001 lead auditor treat ISO/IEC 23894 during an AIMS certification audit?
Which evidence set best supports effective residual AI risk acceptance under Clause 6.1.3?
