## Impact

ElastiCache for Redis offers default encryption at rest as a service, as well as the ability to use your own symmetric customer-managed customer master keys in AWS Key Management Service (KMS).

ElastiCache for Redis at-rest encryption encrypts the following aspects:

* Disk during sync, backup and swap operations
* Backups stored in Amazon S3

## How to Fix

*Resource:* AWS::ElastiCache::ReplicationGroup

* *Arguments:* AtRestEncryptionEnabled \[source,go]

***

Resources: ReplicationGroup: Type: 'AWS::ElastiCache::ReplicationGroup' Properties: ...

* AtRestEncryptionEnabled: True

## 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/storage/appsec-aws-29.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.
