# `AWSConfigRemediation-EnableRedshiftClusterEncryption`
<a name="automation-aws-enable-redshift-encrypt"></a>

 **Description** 

 The `AWSConfigRemediation-EnableRedshiftClusterEncryption` runbook enables encryption on the Amazon Redshift cluster you specify using an AWS Key Management Service (AWS KMS) customer managed key. This runbook should only be used as a baseline to ensure that your Amazon Redshift clusters are encrypted according to minimum recommended security best practices. We recommend encrypting multiple clusters with different customer managed keys. This runbook cannot change the AWS KMS customer managed key used on an already encrypted cluster. To change the AWS KMS customer managed key used to encrypt a cluster, you must first disable encryption on the cluster.
