In practice, this means you can prove you deploy data inventory-level controls on a defined cadence. ## Why it matters The CIS Controls are an industry-vetted, prioritised defence: skipping a safeguard widens the attack surface that the safeguards above and below it assume is closed. Audit frameworks (FedRAMP, PCI DSS, HIPAA) all cite CIS as evidence of due care. ## What an auditor looks for A CIS-aligned reviewer wants to see (a) which Implementation Group you are targeting, (b) a documented owner for the safeguard, and (c) a tooling or process artefact (config, scan output, ticket) that proves the safeguard runs on the cadence the control demands. Within **Protect**, the assessor will trace your implementation back to the catalogue reference (Control 3.13) and look for objective evidence on the latest two assessment cycles. ## How to implement #### Asset Inventory **AWS.** AWS Config Aggregator across every account + region gives a real-time inventory; ship the daily snapshot to S3 and surface drift in Security Hub. **Azure.** Azure Resource Graph plus Defender for Cloud's inventory blade enumerates every subscription; export to Log Analytics for retention and Workbooks for reporting. **GCP.** Cloud Asset Inventory exports a daily feed of every resource and IAM binding; query via BigQuery and alert on appearance/disappearance. **Endpoints.** Pipe MDM telemetry (Intune / Jamf / Workspace ONE) into your CMDB so laptops and phones are inventoried with the same rigour as cloud resources. ### Operational checklist - **Deploy.** Document the trigger, the owner and the cadence. - **Implement.** Document the trigger, the owner and the cadence. - **Protect.** Document the trigger, the owner and the cadence. - **Scope:** data inventory, sensitive, data loss prevention solution, dlp, service, enterprise. ## Evidence to collect - **Vendor Risk Management.** `vendor_risk_management` evidence - **Policy Document.** A signed and version-controlled policy / standard / procedure document. Third-party risk management evidence (assessments, contracts, due diligence) shows supplier oversight. Signed policy or standard documents the safeguard. Focus: Deploy a Data Loss Prevention Solution. ## Common pitfalls - Inventories that exclude SaaS, shadow IT and ephemeral cloud resources (Lambda, Cloud Run, K8s pods) miss the assets where most modern incidents start. ## Related controls in CIS Controls v8 - [**Control 15.1** — Establish and Maintain an Inventory of Service Providers](https://support.icompaas.com/compliance/cis-controls-v8/15-1-establish-and-maintain-an-inventory-of-service-providers) - [**Control 3.8** — Document Data Flows](https://support.icompaas.com/compliance/cis-controls-v8/3-8-document-data-flows) - [**Control 15.2** — Establish and Maintain a Service Provider Management Policy](https://support.icompaas.com/compliance/cis-controls-v8/15-2-establish-and-maintain-a-service-provider-management-policy) - [**Control 15.7** — Securely Decommission Service Providers](https://support.icompaas.com/compliance/cis-controls-v8/15-7-securely-decommission-service-providers) - [**Control 3.2** — Establish and Maintain a Data Inventory](https://support.icompaas.com/compliance/cis-controls-v8/3-2-establish-and-maintain-a-data-inventory) - [**Control 16.4** — Establish and Manage an Inventory of Third-Party Software Components](https://support.icompaas.com/compliance/cis-controls-v8/16-4-establish-and-manage-an-inventory-of-third-party-software-components) ## References - [Center for Internet Security — CIS Controls v8](https://www.cisecurity.org/controls/v8) - Catalogue identifier: `Control 3.13` Topics: governance riskvendor riskvendor managementdata loss preventionsupply chain securityasset inventory ## Related compliance guidance - [SOC 2 compliance: a practical implementation guide for cloud-native SaaS teams](https://support.icompaas.com/compliance/soc-2-trust-services-criteria): Configuration checks like this one are the technical half of a SOC 2 / ISO 27001 programme — the guide shows where they fit, what else an auditor expects, and how to evidence them. - [ISO/IEC 27001:2022 compliance: a practical implementation guide](https://support.icompaas.com/compliance/iso-27001-2022): ISO 27001 Annex A.8 (technological controls) is where cloud hardening evidence lands; the guide shows how to run the ISMS around it.
