BigQuery datasets should all have a default customer-managed encryption key (CMEK) configured
BigQuery datasets use Customer-Managed Encryption Keys (CMEK) rather than Google-managed encryption. The check identifies datasets configured to use a customer-managed key for data-at-rest protection.
What this control checks
Checks each BigQuery dataset for a default CMEK setting; datasets without one fail
