ISO/IEC 27701 — annexes

ISO/IEC 27701 organises its privacy controls into two role-based annexes: Annex A for PII controllers and Annex B for PII processors. Annex D provides an informative mapping to GDPR. This page covers the structure of each annex at the theme level, with reference numbers only.

Quick decision

  • You determine purposes and means of processing → apply Annex A (PII controller controls).
  • You process PII on behalf of a controller → apply Annex B (PII processor controls).
  • You are both, for different processing activities → apply both annexes per the relevant activities.
  • You need to demonstrate GDPR alignment → use Annex D as the planning aid; map PIMS controls to GDPR articles to identify where one control produces evidence for both.

TL;DR

  • Annex A — privacy controls for PII controllers. Covers lawfulness, PII principals' rights, privacy by design, records of processing, transfers, automated decision-making, breach notification.
  • Annex B — privacy controls for PII processors. Covers documented instructions, security, sub-processor oversight, assistance to controllers, breach notification to controller, end-of-processing.
  • Annex D — informative mapping to GDPR articles (planning aid, not a compliance attestation).
  • Role drives selection — controller / processor per processing activity. Many organisations are both.
  • Statement of Applicability records which Annex A and / or B controls are included or excluded.

Annex A — controls for PII controllers (normative)

Annex A organises controls around the controller's privacy obligations. Without reproducing the control text, the high-level structure covers:

ThemeFocus
Lawfulness of processingIdentifying lawful basis (consent, contract, legal obligation, legitimate interests, etc.); managing consent
Transparency to PII principalsPrivacy notice content; modalities for providing information
PII principals' rightsAccess, rectification, erasure, restriction, portability, objection — handling and timing
Privacy by design and by defaultEmbedding privacy into system design, vendor selection, defaults
Records of processing activitiesInventory of processing activities; categories of PII; retention; recipients
Privacy impact assessmentStructured PIA process triggered by risk threshold
Cross-border transferTransfer impact assessment; appropriate safeguards (SCCs, BCRs, adequacy)
Automated decision-making and profilingTransparency, human review, contestability
Personal-data breachDetection, internal escalation, notification to supervisory authority and PII principals
DPO / privacy leadAppointment, responsibilities, independence

How to use Annex A

  • Apply per processing activity where the organisation is the controller.
  • Drive selection from the privacy risk assessment under Clause 6.1.2.
  • Translate controls into operating reality — owned work, cadence, evidence, escalation.
  • Record selection in the Statement of Applicability under Clause 6.1.3.

Annex B — controls for PII processors (normative)

Annex B organises controls around the processor's obligations to the controller and to PII principals indirectly:

ThemeFocus
Documented instructionsProcessing only on the controller's documented instructions; alerting when instructions infringe applicable law
Confidentiality of personnelPersonnel authorised to process PII bound by confidentiality
Security measuresImplementing appropriate technical and organisational measures (ties to ISO 27001 Annex A)
Sub-processor managementAuthorisation, due diligence, contractual safeguards, change notification
Assistance to the controllerAssisting with PII principals' rights handling, DPIAs, prior consultation, breach handling
Breach notification to the controllerNotifying the controller without undue delay
End-of-processingReturn or deletion of PII at end of processing; documented completion evidence
Sub-processor breach notificationCascading breach notification up the chain

How to use Annex B

  • Apply per processing activity where the organisation is the processor.
  • Drive selection from contractual obligations — Data Processing Agreements, SCCs Module 2.
  • Operate Annex B controls together with the relevant ISO 27001 Annex A security controls — most processor security obligations cross-reference into ISMS controls.

Annex D — informative mapping to GDPR

Annex D is an informative cross-reference between the PIMS Annex A / B controls and the GDPR articles. It is a planning aid, not a compliance attestation:

  • A single control in Annex A or B can produce evidence relevant to multiple GDPR articles.
  • Implementing a mapped control does not automatically satisfy the corresponding GDPR article — GDPR legal interpretation is a separate exercise.
  • Annex D is most useful when planning a single PIMS that also produces GDPR operational evidence.

The mapping typically covers:

GDPR areaPIMS controls in Annex A or B
Lawfulness, transparency, fairness (Articles 5–7)Annex A lawfulness, consent, transparency
PII principals' rights (Articles 12–22)Annex A rights handling; Annex B assistance
Controller obligations (Articles 24–30)Annex A records of processing, privacy by design
Processor obligations (Article 28)Annex B in full
Personal-data breach (Articles 33–34)Annex A breach notification + Annex B notification to controller
DPIA (Article 35)Clause 6.1.2 / 6.1.3 privacy risk method plus Annex A privacy-impact-assessment evidence
DPO (Article 37)Annex A DPO appointment + Clause 5.3 roles
Cross-border transfer (Articles 44–50)Annex A transfer impact assessment

How to operationalise the annexes in Modulos

ISO 27701 Annex A and Annex B control selection is tracked as control-level evidence on the ORF-265 requirement (Clause 6.1.3 privacy risk treatment) on OFF-12.

OFF-12 requirementDescriptionAnnex coverage
ORF-265Privacy risk treatment + Statement of ApplicabilityAnnex A controller controls + Annex B processor controls via the SoA
ORF-275Operational planning and controlOperational execution of the selected controls
ORF-276Monitoring, measurement, analysis and evaluationPrivacy-control effectiveness signals
ORF-277 / ORF-278Internal audit + audit programmeSampling control operation

Practical pattern:

  • The SoA artefact is owner-authored documented information attached as evidence on ORF-265. The SoA includes Annex A control decisions (where the organisation is a controller) and Annex B control decisions (where it is a processor).
  • Per-control evidence (control execution records, exception decisions, sub-processor reviews, DSAR responses) is linked to Modulos controls that map to the relevant requirements.
  • The role-determination decisions that drive Annex A vs B selection flow from Clause 4.1 (recorded on ORF-256).
