How Amazon Fraud Detector works with IAM

Before you use IAM to manage access to Amazon Fraud Detector, you should understand what IAM features are available to use with Amazon Fraud Detector. To get a high-level view of how Amazon Fraud Detector and other AWS services work with IAM, see AWS Services That Work with IAM in the IAM User Guide.

Amazon Fraud Detector identity-based policies

With IAM identity-based policies, you can specify allowed or denied actions and resources as well as the conditions under which actions are allowed or denied. Amazon Fraud Detector supports specific actions, resources, and condition keys. To learn about all of the elements that you use in a JSON policy, see IAM JSON Policy Elements Reference in the IAM User Guide.

To get started with Amazon Fraud Detector, we recommend creating an user with access restricted to Amazon Fraud Detector operations and required permissions. You can add other permissions as needed. The following policies provide the required permission to use Amazon Fraud Detector: AmazonFraudDetectorFullAccessPolicy and AmazonS3FullAccess. For more information on setting up Amazon Fraud Detector using these policies see Set up for Amazon Fraud Detector.

Actions

Administrators can use AWS JSON policies to specify who has access to what. That is, which principal can perform actions on what resources, and under what conditions.

The Action element of a JSON policy describes the actions that you can use to allow or deny access in a policy. Include actions in a policy to grant permissions to perform the associated operation.

Policy actions in Amazon Fraud Detector use the following prefix before the action: frauddetector:. For example, to create a rule with the Amazon Fraud Detector CreateRule API operation, you include the frauddetector:CreateRule action in the policy. Policy statements must include either an Action or NotAction element. Amazon Fraud Detector defines its own set of actions that describe tasks that you can perform with this service.

To specify multiple actions in a single statement, separate them with commas as follows:

"Action": [
      "frauddetector:action1",
      "frauddetector:action2"

You can specify multiple actions using wildcards (*). For example, to specify all actions that begin with the word Describe, include the following action:

"Action": "frauddetector:Describe*"

To see a list of Amazon Fraud Detector actions, see Actions Defined by Amazon Fraud Detector in the IAM User Guide.

Resources

Administrators can use AWS JSON policies to specify who has access to what. That is, which principal can perform actions on what resources, and under what conditions.

The Resource JSON policy element specifies the object or objects to which the action applies. As a best practice, specify a resource using its Amazon Resource Name (ARN). For actions that don't support resource-level permissions, use a wildcard (*) to indicate that the statement applies to all resources.

"Resource": "*"

Resource Types Defined by Amazon Fraud Detector lists all Amazon Fraud Detector resource ARNs.

For example, to specify the my_detector detector in your statement, use the following ARN:

"Resource": "arn:aws:frauddetector:us-east-1:123456789012:detector/my_detector"

For more information about the format of ARNs, see Amazon Resource Names (ARNs) and AWS Service Namespaces.

To specify all detectors that belong to a specific account, use the wildcard (*):

"Resource": "arn:aws:frauddetector:us-east-1:123456789012:detector/*"

Some Amazon Fraud Detector actions, such as those for creating resources, cannot be performed on a specific resource. In those cases, you must use the wildcard (*).

"Resource": "*"

To see a list of Amazon Fraud Detector resource types and their ARNs, see Resources Defined by Amazon Fraud Detector in the IAM User Guide. To learn which actions you can specify the ARN of each resource, see Actions Defined by Amazon Fraud Detector.

Condition keys

Administrators can use AWS JSON policies to specify who has access to what. That is, which principal can perform actions on what resources, and under what conditions.

The Condition element specifies when statements execute based on defined criteria. You can create conditional expressions that use condition operators, such as equals or less than, to match the condition in the policy with values in the request. To see all AWS global condition keys, see AWS global condition context keys in the IAM User Guide.

Amazon Fraud Detector defines its own set of condition keys and also supports using some global condition keys. To see all AWS global condition keys, see AWS Global Condition Context Keys in the IAM User Guide.

To see a list of Amazon Fraud Detector condition keys, see Condition Keys for Amazon Fraud Detector in the IAM User Guide. To learn which actions and resources you can use a condition key, see Actions Defined by Amazon Fraud Detector.

Examples

Amazon Fraud Detector resource-based policies

Amazon Fraud Detector does not support resource-based policies.

Authorization Based on Amazon Fraud Detector Tags

You can attach tags to Amazon Fraud Detector resources or pass tags in a request to Amazon Fraud Detector. To control access based on tags, you provide tag information in the condition element of a policy using the aws:ResourceTag/key-name, aws:RequestTag/key-name, or aws:TagKeys condition keys.

Amazon Fraud Detector IAM roles

An IAM role is an entity within your AWS account that has specific permissions.

Using temporary credentials with Amazon Fraud Detector

You can use temporary credentials to sign in with federation, assume an IAM role, or to assume a cross-account role. You obtain temporary security credentials by calling AWS STS API operations such as AssumeRole or GetFederationToken.

Amazon Fraud Detector supports using temporary credentials.

Service-linked roles

Service-linked roles allow AWS services to access resources in other services to complete an action on your behalf. Service-linked roles appear in your IAM account and are owned by the service. An IAM administrator can view but not edit the permissions for service-linked roles.

Amazon Fraud Detector does not support service-linked roles.

Service roles

This feature allows a service to assume a service role on your behalf. This role allows the service to access resources in other services to complete an action on your behalf. Service roles appear in your account and are owned by the account. This means that an administrator can change the permissions for this role. However, doing so might break the functionality of the service.

Amazon Fraud Detector supports service roles.
