— CIS Controls v8, Control 2.4

In plain English

Utilize software inventory tools, when possible, throughout the enterprise to automate the discovery and documentation of installed software. In practice, this means you can prove you utilize software 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.

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 Detect, the assessor will trace your implementation back to the catalogue reference (Control 2.4) and look for objective evidence on the latest two assessment cycles.

How to implement

Endpoint Protection

MDM. Make MDM enrollment a hard gate for device access (Intune compliance + Conditional Access, or Jamf + Okta device trust). Unmanaged devices simply don't get a session token.

EDR. Deploy CrowdStrike / SentinelOne / Defender for Endpoint to every server and laptop; alert on any host that stops sending telemetry for >24h.

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.

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

  • Utilize. Document the trigger, the owner and the cadence.
  • Scope: software inventory, edr, tools, enterprise.

Evidence to collect

  • Edr Scan. edr_scan evidence

EDR telemetry (CrowdStrike, Defender for Endpoint) confirms threat detection. Focus: Utilize Automated Software Inventory Tools.

Common pitfalls

  • Pilot MDM rollouts that quietly exclude executives or engineers; carving out the highest-risk users is the most common audit failure.
  • Inventories that exclude SaaS, shadow IT and ephemeral cloud resources (Lambda, Cloud Run, K8s pods) miss the assets where most modern incidents start.
  • 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.
