ISO/IEC 27701:2025 A.3.4 — Information security roles & responsibilities

What this control requires

Define and allocate security roles and responsibilities related to PII processing. Implementation: Create role descriptions, appoint contacts (e.g., DPO / Privacy Officer). Justification: Clarifies accountability for PII security.

In plain English

Define and allocate security roles and responsibilities related to PII processing. In practice, this means you can prove you implement information security roles-level controls on a defined cadence.

Why it matters

ISO 27701 is the international way to evidence the GDPR principle of accountability: certified PIMS controls translate directly into the records, contracts and rights-handling that supervisory authorities want, and into the privacy-engineering evidence SOC 2 + Privacy auditors and enterprise procurement teams ask for.

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

PIMS auditors expect ISO 27001 to be implemented first and then the 27701-additional controls tested. For PII controllers they look at lawful-basis and rights-handling evidence; for PII processors they look at customer-instructions, sub-processor controls and return/transfer/disposal evidence.

Within Security considerations, the assessor will trace your implementation back to the catalogue reference (Annex A A.3.4) and look for objective evidence on the latest two assessment cycles.

How to implement

Policy Management

Docs. Keep each policy in version-controlled Markdown alongside the code that implements it; ship a signed PDF snapshot at each annual review and link the SHA into the SoA.

Operational checklist

• Implement. Document the trigger, the owner and the cadence.
• Define. Document the trigger, the owner and the cadence.
• Appoint. Document the trigger, the owner and the cadence.
• Scope: information security roles, responsibilities.

Evidence to collect

• Policy Document. A signed and version-controlled policy / standard / procedure document.

Signed policies, procedures, and registers document the safeguard. Focus: Information security roles & responsibilities.

Common pitfalls

• Policies that no engineer has read; the version in Confluence drifts from the version that's actually being enforced.
