## Impact

This policy identifies Customer Master Keys (CMKs) that are not enabled with key rotation. AWS KMS (Key Management Service) allows customers to create master keys to encrypt sensitive data in different services. As a security best practice, it is important to rotate the keys periodically so that if the keys are compromised, the data in the underlying service is still secure with the new keys.

## How to Fix

*Resource:* `AWS::KMS::Key`

* *Attribute*: `EnableKeyRotation` - (Optional) Specifies whether key rotation is enabled. Defaults to false. \[source,go]

***

Type: AWS::KMS::Key Properties: ...

* EnableKeyRotation: true0

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://cortex-docs.paloaltonetworks.com/appsec-rules/iac-security/iam/appsec-aws-7.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
