AWS Customer Managed Keys (CMKs) Without Rotation Enabled

What It Does

This policy template reports any Customer Managed Keys (CMKs) in the AWS account that do not have key rotation enabled. Optionally, this report can be emailed.

AWS Key Management Service (KMS) allows users to rotate the backing key which is key material stored within the KMS which is tied to the key ID of the Customer Created customer master key (CMK). It is recommended that rotation be enabled for all keys.
