### Description{% #description %}

KMS keys should have automatic key rotation enabled to limit the lifetime of cryptographic material, reduce the impact of a compromised key, and meet common compliance requirements. In AWS CloudFormation, `AWS::KMS::Key` resources must define the `EnableKeyRotation` property and set it to `true`. Resources missing this property or with `EnableKeyRotation` set to `false` will be flagged. Enabling rotation activates AWS-managed annual rotation of the key material.

Secure configuration example:

```yaml
MyKMSKey:
  Type: AWS::KMS::Key
  Properties:
    Description: KMS key with rotation enabled
    EnableKeyRotation: true
    KeyPolicy:
      Version: '2012-10-17'
      Statement:
        - Sid: Enable IAM User Permissions
          Effect: Allow
          Principal:
            AWS: !Sub 'arn:aws:iam::${AWS::AccountId}:root'
          Action: 'kms:*'
          Resource: '*'
```
