## Impact

Amazon SageMaker Feature Store enables you to create two types of stores: an online store or offline store. The online store is used for low latency real-time inference use cases whereas the offline store is used for training and batch inference use cases. When you create a feature group for online or offline use you can provide a AWS Key Management Service customer managed key to encrypt all your data at rest. In case you do not provide a AWS KMS key then we ensure that your data is encrypted on the server side using an AWS owned AWS KMS key or AWS managed AWS KMS key.

## How to Fix

To fix this issue, ensure that the `kms_key_id` property in the `aws_sagemaker_domain` resource is set to a valid KMS key ARN or key ID.

*CloudFormation*

To fix this issue, ensure that the `KmsKeyId` property in the `AWS::SageMaker::NotebookInstance` or `AWS::SageMaker::Domain` resource is set to a valid KMS key ARN or key ID.

Example for a SageMaker Notebook Instance:

## Example for a SageMaker Domain: \[source,go]

resource "aws\_sagemaker\_domain" "example" { ...

* kms\_key\_id = "ckv\_kms" }

***

## Resources: MySagemakerNotebookInstance: Type: AWS::SageMaker::NotebookInstance Properties: ... KmsKeyId: arn:aws:kms:us-west-2:123456789012:key/example-key-arn ...

## Resources: MySagemakerDomain: Type: AWS::SageMaker::Domain Properties: ... KmsKeyId: arn:aws:kms:us-west-2:123456789012:key/example-key-arn ...

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

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

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://cortex-docs.paloaltonetworks.com/appsec-rules/iac-security/ai-and-machine-learning/appsec-aws-187.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

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.
