## Impact

This rule verifies whether the EMR (Elastic MapReduce) Cluster security configuration in AWS (Amazon Web Services) is set up to encrypt local disks. Not having an appropriate encryption for local disks exposes the data stored in them to potential attacks, breaches, or unauthorized disclosures. This encryption is critical to protect sensitive data and maintain the confidentiality and integrity of the information.

## How to Fix

*Resource:* aws\_emr\_security\_configuration

* *Arguments:* configuration.EncryptionConfiguration.EnableAtRestEncryption

To fix the issue, you should enable the local disk encryption in your EMR cluster configuration. You will need to specify the "SecurityConfiguration" property in your AWS EMR Cluster resource. This property should reference a Security Configuration resource that has "LocalDiskEncryptionConfiguration" enabled.

## In the code above, the local disk encryption is set to be enabled by specifying the "EncryptionKeyProviderType" and "AwsKmsKey" properties in the "LocalDiskEncryptionConfiguration". This ensures that data stored in the local disks of instances in your EMR cluster is encrypted. The referenced KMS key is used for encryption, ensuring a secure key management process. This process reduces the risk of data compromise or loss by protecting it from unauthorized access which makes the code secure. \[source,go]

resource "aws\_emr\_security\_configuration" "pass" { name = "emrsc\_other"

## configuration = <\<EOF { "EncryptionConfiguration": { "AtRestEncryptionConfiguration": { "S3EncryptionConfiguration": { "EncryptionMode": "SSE-S3" }, "LocalDiskEncryptionConfiguration": { "EnableEbsEncryption": true, "EncryptionKeyProviderType": "AwsKms", "AwsKmsKey": "arn:aws:kms:eu-west-2:680235478471:key/27b6fd31-ca6d-4c71-8dca-06ebd0f94174" } }, "EnableInTransitEncryption": false, "EnableAtRestEncryption": true } } EOF }

## 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-349.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.
