In practice, this means you can prove you establish and maintain service-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. 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 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 **Identify**, the assessor will trace your implementation back to the catalogue reference (Control 15.2) 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 - **Establish And Maintain.** Document the trigger, the owner and the cadence. - **Ensure.** Document the trigger, the owner and the cadence. - **Scope:** service, classification, service provider management policy, service providers, 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: Establish and Maintain a Service Provider Management Policy. ## 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. ## 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 800-53 Rev. 5 SA-5(2)** — Security-Relevant External System Interfaces](https://support.icompaas.com/compliance/nist-sp-800-53-rev-5/sa-5-2-security-relevant-external-system-interfaces) - [**NIST SP 800-171 Rev. 3 3.16.3** — External System Services](https://support.icompaas.com/compliance/nist-sp-800-171-rev-3/3-16-3-external-system-services) - [**BSI C5:2020 SSO-01** — Policies and instructions for controlling and monitoring third parties](https://support.icompaas.com/compliance/bsi-c5-2020/sso-01-policies-and-instructions-for-controlling-and-monitoring-third-parties) - [**ISO/IEC 27001:2022 A.5.19** — Information security in supplier relationships](https://support.icompaas.com/compliance/iso-27001-2022/a-5-19-information-security-in-supplier-relationships) ## Related controls in CIS Controls v8 - [**Control 15.6** — Monitor Service Providers](https://support.icompaas.com/compliance/cis-controls-v8/15-6-monitor-service-providers) - [**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 15.5** — Assess Service Providers](https://support.icompaas.com/compliance/cis-controls-v8/15-5-assess-service-providers) - [**Control 3.8** — Document Data Flows](https://support.icompaas.com/compliance/cis-controls-v8/3-8-document-data-flows) - [**Control 6.6** — Establish and Maintain an Inventory of Authentication and Authorization Systems](https://support.icompaas.com/compliance/cis-controls-v8/6-6-establish-and-maintain-an-inventory-of-authentication-and-authorization-systems) - [**Control 3.13** — Deploy a Data Loss Prevention Solution](https://support.icompaas.com/compliance/cis-controls-v8/3-13-deploy-a-data-loss-prevention-solution) ## References - [Center for Internet Security — CIS Controls v8](https://www.cisecurity.org/controls/v8) - Catalogue identifier: `Control 15.2` Topics: governance riskvendor riskvendor managementsupply chain securityasset inventorycontinuous monitoring ## 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.
