In practice, this means you can prove you policy management-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. 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 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.8.15) and look for objective evidence on the latest two assessment cycles. ## How to implement #### Logging Monitoring **AWS.** Org-trail CloudTrail to a central log archive account, GuardDuty in every region, and Security Hub for cross-source correlation. **Azure.** Pipe every diagnostic setting into a central Log Analytics workspace; onboard Microsoft Sentinel for SIEM/SOAR. **GCP.** Aggregate audit logs in a dedicated logging project with sink to BigQuery; enable Security Command Center Premium and route findings to Chronicle SIEM. #### 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. - **Management.** Document the trigger, the owner and the cadence. - **Scope:** management. ## Evidence to collect - **Infra Scan.** Continuous infrastructure-posture telemetry — AWS Config, Azure Policy compliance, GCP Organisation Policy, Wiz / Prisma findings. SIEM ingestion dashboards (Splunk, Sentinel) confirm logging coverage and retention. ## Common pitfalls - Per-account logging that nobody stitches together at the org level — incidents that cross accounts go undetected for days. - 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. - [**NIST SP 800-171 Rev. 3 3.3.4** — Response to Audit Logging Process Failures](https://support.icompaas.com/compliance/nist-sp-800-171-rev-3/3-3-4-response-to-audit-logging-process-failures) - [**BSI C5:2020 COM-02** — Policy for planning and conducting audits](https://support.icompaas.com/compliance/bsi-c5-2020/com-02-policy-for-planning-and-conducting-audits) - [**SOC 2 (2017 TSC) CC2.3** — External Communication on Internal Control Matters](https://support.icompaas.com/compliance/soc-2-trust-services-criteria/cc2-3-external-communication-on-internal-control-matters) - [**CIS Controls v8 8.2** — Collect Audit Logs](https://support.icompaas.com/compliance/cis-controls-v8/8-2-collect-audit-logs) - [**NIST SP 800-53 Rev. 5 AU-5(5)** — Alternate Audit Logging Capability](https://support.icompaas.com/compliance/nist-sp-800-53-rev-5/au-5-5-alternate-audit-logging-capability) ## Related controls in ISO/IEC 27001:2022 - [**Annex A A.8.11** — Data masking](https://support.icompaas.com/compliance/iso-27001-2022/a-8-11-data-masking) - [**Annex A A.8.6** — Capacity management](https://support.icompaas.com/compliance/iso-27001-2022/a-8-6-capacity-management) - [**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.8.19** — Installation of software on operational systems](https://support.icompaas.com/compliance/iso-27001-2022/a-8-19-installation-of-software-on-operational-systems) - [**Annex A A.8.34** — Protection of information systems during audit testing](https://support.icompaas.com/compliance/iso-27001-2022/a-8-34-protection-of-information-systems-during-audit-testing) - [**Annex A A.8.8** — Management of technical vulnerabilities](https://support.icompaas.com/compliance/iso-27001-2022/a-8-8-management-of-technical-vulnerabilities) ## References - [ISO/IEC JTC 1/SC 27 — ISO/IEC 27001:2022](https://www.iso.org/standard/27001) - Catalogue identifier: `Annex A A.8.15` Topics: governance risklogging monitoringpolicy 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.
