What this control covers
Use DHCP logging on all DHCP servers or Internet Protocol (IP) address management tools to update the enterprise's asset inventory. Review and use logs to update the enterprise's asset inventory weekly, 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.
Google Workspace
Forward the Admin, Login, Drive, Token and Mobile audit logs to Cloud Logging (Workspace BigQuery export). Alert on impossible-travel logins, OAuth-scope grants for high-risk scopes, and external Drive sharing of sensitive labels.
GitHub
Apply branch protection on default and release branches: require PR review, status checks, signed commits, linear history, and dismiss stale reviews on new commits. Use CODEOWNERS for required reviewers, Dependabot + CodeQL for SAST, and the Dependency graph / SBOM export for vendor disclosures.
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: Use Dynamic Host Configuration Protocol (DHCP) Logging to Update Enterprise Asset Inventory.
