Enable and Configure Encryption at Rest using Customer Key Management for One Project

Note

Groups and projects are synonymous terms. Your {GROUP-ID} is the same as your project ID. For existing groups, your group/project ID remains the same. The resource and corresponding endpoints use the term groups.

Note
Feature unavailable in Free and Shared-Tier Clusters

This feature is not available for M0 (Free Tier), M2, and M5 clusters. To learn more about which features are unavailable, see Atlas M0 (Free Tier), M2, and M5 Limitations.

Enables, disables, and configures Encryption at Rest using Customer Key Management for an Atlas project with one of the following providers:

After configuring at least one Encryption at Rest using Customer Key Management provider for the Atlas project, Project Owners can enable Encryption at Rest using Customer Key Management for each Atlas cluster for which they require encryption. The Encryption at Rest using Customer Key Management provider does not have to match the cluster cloud service provider.

Atlas does not automatically rotate user-managed encryption keys. Defer to your preferred Encryption at Rest using Customer Key Management provider's documentation and guidance for best practices on key rotation. Atlas automatically creates a 365-day key rotation alert when you configure Encryption at Rest using Customer Key Management using your Key Management in an Atlas project.

Note

Atlas encrypts all storage whether or not you use your own key management.

To learn more about key management, see Encryption at Rest using Customer Key Management, including prerequisites and restrictions.

The Atlas API authenticates using HTTP Digest Authentication. Provide a programmatic API public key and corresponding private key as the username and password when constructing the HTTP request.

PATCH /groups/{GROUP-ID}/encryptionAtRest
Path Element
Necessity
Description
GROUP-ID
Required
Unique identifier for the project.

This endpoint might use any of the HTTP request query parameters available to all Atlas API resources. All of these are optional.

Name
Type
Necessity
Description
Default
pretty
boolean
Optional
Flag indicating whether the response body should be in a prettyprint format.
false
envelope
boolean
Optional

Flag indicating if Atlas should wrap the response in a JSON envelope.

This option may be needed for some API clients. These clients cannot access the HTTP response headers or status code. To remediate this, set envelope=true in the query.

For endpoints that return one result, the response body includes:

status
HTTP response code
envelope
Expected response body
false

The required request body parameters depend on whether Encryption at Rest using Customer Key Management is currently enabled:

  • If you have enabled Encryption at Rest using Customer Key Management, Atlas requires all of the parameters for the desired encryption provider.

    • If you want to use AWS KMS, Atlas requires all the fields in the awsKms document.
    • If you want to use Azure Key Vault, Atlas requires all the fields in the azureKeyVault document.
    • If you want to use Google Cloud KMS, Atlas requires all the fields in the googleCloudKms document.
  • If you have enabled Encryption at Rest using Customer Key Management, administrators can pass only the changed fields for the awsKms, azureKeyVault, or googleCloudKms document to update the configuration to this endpoint.

Required
AWS KMS configuration details and whether Encryption at Rest using Customer Key Management is enabled for an Atlas project.
awsKms
.accessKeyID
string
Optional
IAM access key ID with permissions to access the customer master key (awsKms.customerMasterKeyID).
awsKms
.customerMasterKeyID
string
Optional
AWS customer master key used to encrypt and decrypt the MongoDB master keys.
awsKms
.enabled
boolean
Optional
Flag that indicates whether Encryption at Rest using Customer Key Management is enabled for an Atlas project. To disable Encryption at Rest using Customer Key Management, pass only this parameter with a value of false. When you disable Encryption at Rest using Customer Key Management, Atlas removes the configuration details.
awsKms
.region
string
Optional

AWS region in which the AWS customer master key exists:

Region Value
Corresponding Region in Console
US_EAST_1

awsKms
.roleId
string
Optional
ID of an AWS IAM role authorized to manage an AWS customer master key. To find the ID for an existing IAM role, send a GET request to the cloudProviderAccess API endpoint.

awsKms
.valid
boolean

Specifies whether the encryption key set for the provider is valid and may be used to encrypt and decrypt data. This field is a system-controlled status report and is read-only.

The following example enables and configures Encryption at Rest using Customer Key Management for an Atlas project using AWS KMS:

1curl --user "{PUBLIC-KEY}:{PRIVATE-KEY}" --digest \
2 --header "Accept: application/json" \
3 --header "Content-Type: application/json" \
4 --request PATCH "https://cloud.mongodb.com/api/atlas/v1.0/groups/{GROUP-ID}/encryptionAtRest?pretty=true" \
