# `AWSConfigRemediation-EncryptSNSTopic`
<a name="automation-aws-encrypt-sns-topic"></a>

 **Description** 

 The `AWSConfigRemediation-EncryptSNSTopic` runbook enables encryption on the Amazon Simple Notification Service (Amazon SNS) topic 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 SNS topics are encrypted according to minimum recommended security best practices. We recommend encrypting multiple topics with different customer managed keys.
