CIS · Control 2.2 · Priority: critical · Component: Identify

What this control covers

Ensure that only currently supported software is designated as authorized in the software inventory for enterprise assets. If software is unsupported, yet necessary for the fulfillment of the enterprise's mission, document an exception detailing mitigating controls and residual risk acceptance. For any unsupported software without an exception documentation, designate as unauthorized. Review the software list to verify software support at least monthly, or more frequently.

Why it matters

Risk is the language an executive team understands; this control connects technical reality to board-level decisions and budget allocation.

How to implement

AWS

Codify the policy intent as SCPs, AWS Config conformance packs, and Security Hub standards so the cloud enforces what the document says.

Azure

Codify in Azure Policy initiatives (built-in regulatory compliance for CIS, ISO 27001, SOC 2, HIPAA) and assign at management-group level.

GCP

Cloud Asset Inventory exports a daily snapshot of every resource and IAM policy to BigQuery; combine with Org Policy for tag enforcement.

On-premises

Maintain a policy library with a documented review cadence (annual minimum); store in your GRC tool with attestation tracking. Map each policy to controls so an audit pull cites the exact policy clause.

Evidence to collect

  • policy_document — A signed, version-controlled policy stating leadership intent and the named owner.

Signed policy or standard documents the safeguard. Focus: Ensure Authorized Software is Currently Supported.
