ISO/IEC 27001:2022 — Clauses 4–10 implementation guide

ISO/IEC 27001 follows the Annex SL harmonized structure. Clauses 4–10 describe how to run an ISMS; the ISMS-specific content (information-security policy in 5.2, information-security risk assessment in 6.1.2, risk treatment and the mandatory Statement of Applicability in 6.1.3) sits inside the shared backbone. This page is the implementation playbook — not a restatement of the standard text.

Quick decision

  • You already operate a security program (SOC 2, NIST CSF) → Clauses 4–10 will require formalising the management-system spine; gap focus on Clause 6.1.3 d SoA and Clause 9 audit + review.
  • You are starting from scratch → stand up the Annex SL backbone (4 Context, 5 Leadership, 6 Planning, 7 Support, 8 Operation, 9 Performance evaluation, 10 Improvement) and produce the SoA in parallel.
  • You need to write the risk assessment method (6.1.2) → define criteria, thresholds, cadence, approval authority. Lifecycle, not one-shot.
  • You need to build the SoA (6.1.3 d) → every one of the 93 Annex A controls gets a position — included with justification, or excluded with justification.

TL;DR

  • Annex SL backbone shared with ISO 42001 / 27701 / 9001 — Clauses 4 (Context), 5 (Leadership), 6 (Planning), 7 (Support), 8 (Operation), 9 (Performance evaluation), 10 (Improvement).
  • Information-security content inside the shared clauses: 5.2 information-security policy; 6.1.2 information-security risk assessment; 6.1.3 information-security risk treatment + mandatory Statement of Applicability (6.1.3 d); 6.2 information-security objectives.
  • Annex A is normative — 93 controls in 4 themes. The SoA covers all of them.
  • Internal audit (9.2) + management review (9.3) + corrective action (10.2) = the operating loop auditors use to evaluate conformity and effectiveness.
  • Modulos models Clauses 4–10 via OFF-9 (28 ORF requirements) and MFF-9 (2 MRF requirements).

Clause 4 — Context of the organization

Goal: define the ISMS boundaries and the reality it operates in.

What to implement:

  • ISMS scope statement (Clause 4.3) — boundaries, locations, systems, interfaces with activities performed by other organisations.
  • Interested parties (4.2) — customers, regulators, contracts, staff, suppliers.
  • ISMS description (4.4) — how the management system fits into existing governance.

Common pitfalls:

  • Scope that is "everything" (too broad to operate) or "almost nothing" (not credible).
  • Scope not updated when systems, vendors or architecture change.

Clause 5 — Leadership

Goal: make security governance real — leadership commitment, policy direction, explicit responsibilities.

What to implement:

  • An information-security policy (5.2) — usable and auditable, not aspirational.
  • Roles and authorities (5.3) — who approves, who owns risks, who reviews.
  • A governance cadence and escalation path — incidents, exceptions, nonconformities.

Common pitfalls:

  • A policy that reads like marketing but doesn't bind decisions.
  • Ambiguous authority — "everyone is responsible" usually means "no one is accountable".

Clause 6 — Planning

Goal: turn intent into a plan — risk method, treatment, objectives, change planning.

What to implement:

  • A risk-assessment method (Clause 6.1.2) — criteria, thresholds, cadence, approval authority.
  • A risk-treatment plan (6.1.3) — selecting controls from Annex A + any additional controls.
  • The Statement of Applicability (6.1.3 d) — mandatory documented information covering all 93 Annex A controls with inclusion/exclusion justification.
  • Measurable information-security objectives (6.2) — owners, measures, review cadence.
  • Planning of changes (6.3) — what triggers reassessment of the ISMS itself (organisational change, system change, vendor change, regulatory change).

Common pitfalls:

  • Treating the risk assessment as a one-time exercise rather than a lifecycle mechanism.
  • An SoA that copies Annex A control text into a spreadsheet but doesn't link to the risk register.
  • Objectives that aren't measurable or aren't linked to any governance decisions.

Go deeper: ISMS foundations — scope and SoA.

Clause 7 — Support

Goal: ensure people, resources, competence, awareness and controlled documentation to run the ISMS reliably.

What to implement:

  • Resource planning — time and expertise for risk, control execution, documentation, review.
  • Role-based competence and training, including reviewers and approvers.
  • Communication — who needs to know what, when (internal and external).
  • Documented-information discipline (7.5) — versioning, review cadence, access control.

Common pitfalls:

  • Documentation debt — artefacts exist but no one owns them; they silently rot.
  • Uncontrolled working docs — critical decisions live in chat threads and get lost.

Clause 8 — Operation

Goal: run security governance as an operational system — Annex A control execution, periodic reassessment, supplier management.

What to implement:

  • Operational planning and control (8.1) — the processes that execute the selected Annex A controls.
  • Periodic information-security risk assessment (8.2) — operational re-assessment as systems, suppliers and the threat environment change.
  • Risk-treatment execution (8.3) — implementing controls and tracking residual risk acceptance.
  • Supplier governance — Annex A theme 5 covers supplier relationships including critical AI/ML vendors and cloud providers.

Common pitfalls:

  • Annex A controls treated as policy artefacts rather than operational practices.
  • Monitoring exists but isn't connected to governance decisions or corrective actions.
  • Supplier reviews stop at onboarding — no periodic reassessment.

Go deeper: Annex A (controls reference).

Clause 9 — Performance evaluation

Goal: prove the ISMS works — monitoring, internal audit, management review.

What to implement:

  • Monitoring and measurement (9.1) — what signals indicate the ISMS controls are working (or failing).
  • Internal audit programme (9.2) — scope, cadence, sampling, auditor competence.
  • Management review (9.3) — what leadership reviews, how often, what outcomes are expected. Inputs include audit findings, monitoring results, supplier evaluations, nonconformities, resourcing.

Common pitfalls:

  • "Internal audit" treated as document review only — weak signal that doesn't catch operational gaps.
  • Management review becomes a status meeting, not a decision point.

Clause 10 — Improvement

Goal: make failures productive — fix nonconformities and continually improve the system.

What to implement:

  • Nonconformity and corrective action (10.2) — ownership, deadlines, root cause analysis, effectiveness verification.
  • Continual improvement (10.1) — driven by audits, incidents, monitoring, stakeholder feedback.

Common pitfalls:

  • Corrective actions closed without verifying effectiveness.
  • Improvements tracked informally without traceability back to the trigger.

How to operationalise Clauses 4–10 in Modulos

The OFF-9 framework template maps the 28 Clauses 4–10 requirements to ISMS-level governance work:

ORF-22210.1Continual improvement

MFF-9 (app-level) maps the per-AI-system overlap with the ISMS:

RequirementClauseTopic
MRF-2218.2Information-security risk assessment (operational, per AI system)
MRF-2228.3Information-security risk treatment (operational, per AI system)

Operating rules:

  • Scope, policy, risk method, SoA, internal audit, management review live on OFF-9. One organisation project per organisation.
  • AI-system-specific information-security risk + treatment live on MFF-9. Each AI-system MFF-9 project gets its own evidence trail.
  • The Statement of Applicability is owner-authored documented information stored as control-level evidence on ORF-205. Modulos does not provide a dedicated SoA workflow surface.

Integrated Management System (IMS) with ISO 42001 / 27701

Clauses 4–10 are shared with ISO 42001 (AIMS) and ISO 27701 (PIMS) — document control, internal audit, management review, corrective action work the same way across all three. What stays standard-specific:

  • ISO 27001: information-security risk and Annex A (normative) information-security controls.
  • ISO 42001: AI policy (5.2), AI risk + impact (6.1.2/3/4), Annex A (informative) AI lifecycle and data controls.
  • ISO 27701: privacy risk, PII processor / controller distinctions, privacy controls.
