Description

Ensure that your Google Cloud Dataproc clusters on Compute Engine are encrypted with Customer-Managed Keys (CMKs) in order to control the cluster data encryption/decryption process. You can create and manage your own Customer-Managed Keys (CMKs) with Cloud Key Management Service (Cloud KMS). Cloud KMS provides secure and efficient encryption key management, controlled key rotation, and revocation mechanisms.

    Ensure that your Google Cloud Dataproc clusters on Compute Engine are encrypted with Customer-Managed Keys (CMKs) in order to control the cluster data encryption/decryption process. You can create and manage your own Customer-Managed Keys (CMKs) with Cloud Key Management Service (Cloud KMS). Cloud KMS provides secure and efficient encryption key management, controlled key rotation, and revocation mechanisms.
  impact: |
    Without Customer-Managed Keys, you have less control over data encryption and key management, potentially impacting compliance requirements and security controls.
  remediation: |
    Re-create your Dataproc clusters with Customer-Managed Keys using Cloud KMS. Configure a key ring and CMK in Cloud KMS, then specify the key when creating the cluster using the '--gce-pd-kms-key' flag or through the console.
