## Impact

This rule is checking to ensure that Neptune snapshots are encrypted using a Customer Managed Key (CMK). This is important because Neptune snapshots can contain sensitive data, and encryption helps protect this data from unauthorized access. Specifically, using a Customer Managed Key gives you full control and autonomy over the key management, including its rotation, enabling auditing, and defining the permissions who can use this key. Unencrypted snapshots, or snapshots encrypted with less secure options, can compromise data security, potentially leading to data breaches. Hence, not adhering to this rule can pose significant data security risks.

## How to Fix

*Resource:* aws\_neptune\_cluster\_snapshot

* *Arguments:* kms\_key\_id

To fix this issue, you need to ensure that Neptune snapshots are encrypted using a KMS CMK. Use the `kms_key_id` argument in the `aws_neptune_cluster_snapshot` resource to specify the CMK.

## This code is secure because it ensures that Neptune snapshots are encrypted with the specified AWS Key Management Service (KMS) customer managed key (CMK). Encryption of sensitive data at rest adds another layer of security and makes it harder for unauthorized individuals to access your data. \[source,go]

resource "aws\_kms\_key" "key" { description = "Key for encrypting Neptune snapshots" deletion\_window\_in\_days = 7 }

## resource "aws\_neptune\_cluster\_snapshot" "snapshot" { cluster\_identifier = aws\_neptune\_cluster.default.id snapshot\_identifier = "neptune-snapshot-${aws\_neptune\_cluster.default.id}" kms\_key\_id = aws\_kms\_key.key.arn //specify the CMK here }

## 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-280.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.
