### In plain English

Establishes automated or manual procedures for inventorying assets throughout their lifecycle, ensuring accuracy and consistency. In practice, this means you can prove you risk inventory-level controls on a defined cadence.

## Why it matters

BSI C5 is the default cloud-security baseline German public-sector buyers and many DAX-listed enterprises expect; gaps here directly block procurement in the DACH region and frequently appear as must-have items in EU public-tender documents.

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 C5 attesting auditor (under ISAE 3000 / IDW PS 860) tests both the design and — for a Type 2 — the operating effectiveness over the attestation period. For each criterion they look for both the Basic and any in-scope Additional objectives.

Within **Asset Management**, the assessor will trace your implementation back to the catalogue reference (Criterion AM-01) 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.

#### Cloud Posture

**CSPM.** Run Wiz / Prisma / Defender for Cloud / Security Command Center over every account; auto-ticket findings above your accepted-risk threshold.

#### 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

-   **Risk.** Document the trigger, the owner and the cadence.
-   **Asset.** Document the trigger, the owner and the cadence.
-   **Data.** Document the trigger, the owner and the cadence.
-   **Policy.** Document the trigger, the owner and the cadence.
-   **Scope:** inventory, cloud customer data, changes, management.

## Evidence to collect

-   **Policy Document.** A signed and version-controlled policy / standard / procedure document.
-   **Infra Scan.** Continuous infrastructure-posture telemetry — AWS Config, Azure Policy compliance, GCP Organisation Policy, Wiz / Prisma findings.

Signed policy or standard documents the safeguard. Focus: Asset Inventory.

## 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.
-   Treating CSPM findings as a backlog instead of a hot queue: findings older than the policy SLA accumulate until the auditor asks why.
-   Policies that no engineer has read; the version in Confluence drifts from the version that's actually being enforced.
