ISO/IEC 42001:2023·Annex A A.6.2.7·high·Component: Technological controls

What this control requires

Data preparation processes shall be defined and controlled to preserve integrity, reduce bias risks, and maintain reproducibility.
— ISO/IEC 42001:2023, Annex A A.6.2.7

In plain English

Data preparation processes shall be defined and controlled to preserve integrity, reduce bias risks, and maintain reproducibility. In practice, this means you can prove you define data-level controls on a defined cadence.

Why it matters

ISO 42001 is the first audited evidence regulators, customers and investors can ask for that you are managing AI risk. Each Annex A control is a check-box in that audit; it is also the management system enterprises are starting to require from AI vendors before an MSA can be signed.

This control is rated high. Auditors expect a named owner, a remediation SLA, and a tooling artefact that evidences continuous operation.

What an auditor looks for

An ISO 42001 auditor verifies you have an AI policy, a risk-based system of impact assessments for each AI system, lifecycle controls from data acquisition through retirement, and third-party-AI controls that pierce the vendor's wrapper to underlying model behaviour.

Within Technological controls, the assessor will trace your implementation back to the catalogue reference (Annex A A.6.2.7) and look for objective evidence on the latest two assessment cycles.

How to implement

Configuration Management

Policy-as-code. Codify the control as Service Control Policies (AWS), Azure Policy initiatives, or Organisation Policy (GCP) so the platform enforces what the document promises.

IaC. Gate Terraform / Pulumi / CloudFormation changes with Checkov / tfsec / OPA so misconfigurations never reach production.

Drift. Run a CSPM (Wiz / Prisma / Defender for Cloud / Security Command Center) over every account and route findings to a single risk register.

Operational checklist

  • Define. Document the trigger, the owner and the cadence.
  • Scope: data, risk.

Evidence to collect

  • Code Repo Scan. Source-control evidence — branch protection, required reviewers, CI status, SCA / SAST reports.
  • Infra Scan. Continuous infrastructure-posture telemetry — AWS Config, Azure Policy compliance, GCP Organisation Policy, Wiz / Prisma findings.

Repository and infrastructure evidence should demonstrate that data preparation workflows are defined, versioned, and controlled to preserve integrity, reduce bias risk, and support repeatability. Focus: Preparation of data.

Common pitfalls

  • Manual cloud-console changes that never make it back to Terraform — drift accumulates until the next outage forces a reconciliation.
