How AWS Cost Management works with IAM

AWS Cost Management integrates with the AWS Identity and Access Management (IAM) service so that you can control who in your organization has access to specific pages on the AWS Cost Management console. You can control access to invoices and detailed information about charges and account activity, budgets, payment methods, and credits.

For more information about how to activate access to the Billing and Cost Management Console, see Tutorial: Delegate Access to the Billing Console in the IAM User Guide.

Before you use IAM to manage access to AWS Cost Management, learn what IAM features are available to use with AWS Cost Management.

To get a high-level view of how AWS Cost Management and other AWS services work with most IAM features, see AWS services that work with IAM in the IAM User Guide.

Identity-based policies for AWS Cost Management

Supports identity-based policies: Yes

Identity-based policies are JSON permissions policy documents that you can attach to an identity, such as an IAM user, group of users, or role. These policies control what actions users and roles can perform, on which resources, and under what conditions. To learn how to create an identity-based policy, see Define custom IAM permissions with customer managed policies in the IAM User Guide.

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. To learn about all of the elements that you can use in a JSON policy, see IAM JSON policy elements reference in the IAM User Guide.

Resource-based policies within AWS Cost Management

Supports resource-based policies: No

Resource-based policies are JSON policy documents that you attach to a resource. Examples of resource-based policies are IAM role trust policies and Amazon S3 bucket policies. In services that support resource-based policies, service administrators can use them to control access to a specific resource. For the resource where the policy is attached, the policy defines what actions a specified principal can perform on that resource and under what conditions. You must specify a principal in a resource-based policy. Principals can include accounts, users, roles, federated users, or AWS services.

To enable cross-account access, you can specify an entire account or IAM entities in another account as the principal in a resource-based policy. For more information, see Cross account resource access in IAM in the IAM User Guide.

Policy actions for AWS Cost Management

Supports policy actions: Yes

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.

To see a list of AWS Cost Management actions, see Actions defined by AWS Cost Management in the Service Authorization Reference.

Policy actions in AWS Cost Management use the following prefix before the action:

ce

To specify multiple actions in a single statement, separate them with commas.

"Action": [
      "ce:action1",
      "ce:action2"
         ]

To view examples of AWS Cost Management identity-based policies, see Identity-based policy examples for AWS Cost Management.

Policy resources for AWS Cost Management

Supports policy resources: Partial

Policy resources are only supported for monitors, subscriptions, and cost categories.

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": "*"

To see a list of AWS Cost Explorer resource types, see Actions, resources, and condition keys for AWS Cost Explorer in the Service Authorization Reference.

To view examples of AWS Cost Management identity-based policies, see Identity-based policy examples for AWS Cost Management.

Policy condition keys for AWS Cost Management

Supports service-specific policy condition keys: Yes

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.

To see a list of AWS Cost Management condition keys, actions, and resources, see Condition keys for AWS Cost Management in the Service Authorization Reference.

Access control lists (ACLs) in AWS Cost Management

Supports ACLs: No

Access control lists (ACLs) control which principals (account members, users, or roles) have permissions to access a resource. ACLs are similar to resource-based policies, although they do not use the JSON policy document format.

Attribute-based access control (ABAC) with AWS Cost Management

Supports ABAC (tags in policies): Partial

ABAC (tags in policies) are only supported for monitors, subscriptions, and cost categories.

Attribute-based access control (ABAC) is an authorization strategy that defines permissions based on attributes called tags. You can attach tags to IAM entities and AWS resources, then design ABAC policies to allow operations when the principal's tag matches the tag on the resource.

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.

If a service supports all three condition keys for every resource type, then the value is Yes for the service. If a service supports all three condition keys for only some resource types, then the value is Partial.

For more information about ABAC, see Define permissions with ABAC authorization in the IAM User Guide. To view a tutorial with steps for setting up ABAC, see Use attribute-based access control (ABAC) in the IAM User Guide.

Using Temporary credentials with AWS Cost Management

Supports temporary credentials: Yes

Temporary credentials provide short-term access to AWS resources and are automatically created when you use federation or switch roles. AWS recommends that you dynamically generate temporary credentials instead of using long-term access keys. For more information, see Temporary security credentials in IAM and AWS services that work with IAM in the IAM User Guide.

Forward access sessions for AWS Cost Management

Supports forward access sessions (FAS): Yes

Forward access sessions (FAS) use the permissions of the principal calling an AWS service, combined with the requesting AWS service to make requests to downstream services. For policy details when making FAS requests, see Forward access sessions.

Service roles for AWS Cost Management

Supports service roles: Yes

A service role is an IAM role that a service assumes to perform actions on your behalf. An IAM administrator can create, modify, and delete a service role from within IAM. For more information, see Create a role to delegate permissions to an AWS service in the IAM User Guide.
