Giving Amazon Personalize permission to use your AWS KMS key

If you specify a AWS Key Management Service (AWS KMS) key when you use the Amazon Personalize console or APIs, or if you use your AWS KMS key to encrypt an Amazon S3 bucket, you must grant Amazon Personalize permission to use your key. To grant permissions, your AWS KMS key policy and IAM policy attached to your service role must grant Amazon Personalize permission to use your key. This applies for creating the following in Amazon Personalize.

Your AWS KMS key policy and IAM policies must grant permissions for the following actions:

Revoking AWS KMS key permissions after creating a resource can lead to issues when creating a filter or getting recommendations. For more information about AWS KMS policies, see Using key policies in AWS KMS in the AWS Key Management Service Developer Guide. For information on creating an IAM policy, see Creating IAM policies in the IAM User Guide. For information on attaching an IAM policy to role, see Adding and removing IAM identity permissions in the IAM User Guide.

Key policy example

The following key policy example grants Amazon Personalize and your role the minimum permissions for the preceding Amazon Personalize operations. If you specify a key when you create a dataset group and want to export data from a dataset, your key policy must include the GenerateDataKeyWithoutPlaintext action.

{
  "Version": "2012-10-17",
  "Id": "key-policy-123",
  "Statement": [
    {
      "Sid": "Allow use of the key",
      "Effect": "Allow",
      "Principal": {
        "AWS": "arn:aws:iam::<account-id>:role/<personalize-role-name>",
        "Service": "personalize.amazonaws.com"
      },
      "Action": [
                "kms:Decrypt",
                "kms:GenerateDataKey",
                "kms:DescribeKey",
                "kms:CreateGrant",
                "kms:ListGrants"
            ],
      "Resource": "*"
    }
  ]
}

IAM policy example

The following IAM policy example grants a role the minimum AWS KMS permissions required for the preceding Amazon Personalize operations. For dataset import jobs, only the AWS KMS key policy needs to grant permissions.

{
    "Version": "2012-10-17",
    "Statement": [
        {
            "Effect": "Allow",
            "Action": [
                "kms:Decrypt",
                "kms:GenerateDataKey",
                "kms:DescribeKey",
                "kms:ListGrants"
            ],
            "Resource": "*"
        }
    ]
}
