In practice, this means you can prove you policy assets-level controls on a defined cadence. ## Why it matters ISO 27001 certification depends on showing each Annex A control is either implemented or explicitly justified for exclusion in the Statement of Applicability (SoA). Certification bodies sample controls during surveillance audits, and a missing SoA entry — or implementation that doesn't match the SoA wording — is a finding. ## What an auditor looks for An ISO 27001 lead auditor looks for: (1) an SoA entry covering the control with justification, (2) a documented procedure or policy implementing it, (3) records that prove the procedure runs (logs, tickets, training records) and (4) management-review evidence that effectiveness is monitored. Within **Technological controls**, the assessor will trace your implementation back to the catalogue reference (Annex A A.8.3) 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 - **Policy.** Document the trigger, the owner and the cadence. - **Information.** Document the trigger, the owner and the cadence. - **Management.** Document the trigger, the owner and the cadence. - **Access Control.** Document the trigger, the owner and the cadence. - **Scope:** assets, information, management, access restriction. ## Evidence to collect - **Identity Scan.** IAM / IdP exports — Entra ID, Okta, IAM Identity Center, Workspace directory — showing accounts, roles, MFA state and last sign-in. - **Infra Scan.** Continuous infrastructure-posture telemetry — AWS Config, Azure Policy compliance, GCP Organisation Policy, Wiz / Prisma findings. IAM policy evaluations (AWS IAM Access Analyzer, Azure PIM) prove information access is limited to approved roles. ## Common pitfalls - Policies that no engineer has read; the version in Confluence drifts from the version that's actually being enforced. ## How it maps to other frameworks Computed from shared tags, control component and key-operation subjects — handy when you are reconciling controls across an audit. - [**SOC 2 (2017 TSC) C1.2** — Confidential Information Disposal](https://support.icompaas.com/compliance/soc-2-trust-services-criteria/c1-2-confidential-information-disposal) - [**HIPAA (45 CFR Part 164) 164.522(a)(3)** — Documentation](https://support.icompaas.com/compliance/hipaa/164-522-a-3-documentation) - [**NIST SP 800-171 Rev. 3 3.1.5** — Least Privilege](https://support.icompaas.com/compliance/nist-sp-800-171-rev-3/3-1-5-least-privilege) - [**NIST SP 800-53 Rev. 5 AC-4(20)** — Approved Solutions](https://support.icompaas.com/compliance/nist-sp-800-53-rev-5/ac-4-20-approved-solutions) - [**GDPR Article 8** — Conditions applicable to child's consent in relation to information society services](https://support.icompaas.com/compliance/gdpr/article-8-conditions-applicable-to-child-s-consent-in-relation-to-information-society) ## Related controls in ISO/IEC 27001:2022 - [**Annex A A.8.14** — Redundancy of information processing facilities](https://support.icompaas.com/compliance/iso-27001-2022/a-8-14-redundancy-of-information-processing-facilities) - [**Annex A A.5.10** — Acceptable use of information and other associated assets](https://support.icompaas.com/compliance/iso-27001-2022/a-5-10-acceptable-use-of-information-and-other-associated-assets) - [**Annex A A.8.8** — Management of technical vulnerabilities](https://support.icompaas.com/compliance/iso-27001-2022/a-8-8-management-of-technical-vulnerabilities) - [**Annex A A.8.17** — Clock synchronization](https://support.icompaas.com/compliance/iso-27001-2022/a-8-17-clock-synchronization) - [**Annex A A.8.32** — Change management](https://support.icompaas.com/compliance/iso-27001-2022/a-8-32-change-management) - [**Annex A A.8.33** — Test information](https://support.icompaas.com/compliance/iso-27001-2022/a-8-33-test-information) ## References - [ISO/IEC JTC 1/SC 27 — ISO/IEC 27001:2022](https://www.iso.org/standard/27001) - Catalogue identifier: `Annex A A.8.3` Topics: governance riskpolicy management ## Related compliance guidance - [ISO/IEC 27001:2022 compliance: a practical implementation guide](https://support.icompaas.com/compliance/iso-27001-2022): Start with the full ISO 27001 implementation guide — scope, roadmap, evidence and how the assessment runs. - [SOC 2 compliance: a practical implementation guide for cloud-native SaaS teams](https://support.icompaas.com/compliance/soc-2-trust-services-criteria): Most companies that hold ISO 27001 also need a SOC 2 report for North American customers, and the two share most of their technical controls.
