Identity-based policies for Account 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.

Identity-based policy examples for Account Management

Resource-based policies within Account 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 Amazon Web Services 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 Account Management

Supports policy actions: Yes

Administrators can use Amazon 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 Account Management actions, see Actions defined by Amazon Account Management in the Service Authorization Reference.

Policy actions in Account Management use the following prefix before the action.


account

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


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

You can specify multiple actions using wildcards (*). For example, to specify all actions that work with an Amazon Web Services account's alternate contacts, include the following action.


"Action": "account:*AlternateContact"

To view examples of Account Management identity-based policies, see Identity-based policy examples for Amazon Account Management.

Policy resources for Account Management

Supports policy resources: Yes

Administrators can use Amazon 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": "*"

The Account Management service supports the following specific resource types in an IAM policy's Resources element to help you filter the policy and distinguish between these types of Amazon Web Services accounts:

account

This resource type matches only standalone Amazon Web Services accounts that are not member accounts in an organization managed by the Amazon Organizations service.
accountInOrganization

This resource type matches only Amazon Web Services accounts that are member accounts in an organization managed by the Amazon Organizations service.

To see a list of Account Management resource types and their ARNs, see Resources defined by Amazon Account Management in the Service Authorization Reference. To learn with which actions you can specify the ARN of each resource, see Actions defined by Amazon Account Management.

To view examples of Account Management identity-based policies, see Identity-based policy examples for Amazon Account Management.

Policy condition keys for Account Management

Supports service-specific policy condition keys: Yes

Administrators can use Amazon 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 Amazon global condition keys, see Amazon global condition context keys in the IAM User Guide.

The Account Management service supports the following condition keys that you can use to provide fine-grained filtering for your IAM policies:

account:TargetRegion

This condition key takes an argument that consists of a list of Amazon Region codes. It lets you filter the policy to affect only those actions that apply to the specified Regions.
account:AlternateContactTypes

This condition key takes a list of alternate contact types:
- BILLING
- OPERATIONS
- SECURITY
Using this key lets you filter the request to only those actions that target the specified alternate contact types.
account:AccountResourceOrgPaths

This condition key takes an argument that consists of a list of paths through your organization's hierarchy to specific organizational units (OU). It lets you filter the policy to affect only target accounts in a matching OU.
```
o-aa111bb222/r-a1b2/ou-a1b2-f6g7h111/*
```
account:AccountResourceOrgTags

This condition key takes an argument that consists of a list of tag keys and values. It lets you filter the policy to affect only those accounts that are members of an organization and that are tagged with the specified tag keys and values.
account:EmailTargetDomain

This condition key takes an argument that consists of a list of email domains. It lets you filter the policy to affect only those actions that match the specified email domains. This condition key is case-insensitive. You should use StringEqualsIgnoreCase instead of StringEquals in the condition block of the policy to control the action based on the target email address domain. Here is a sample policy allowing the account:StartPrimaryEmailUpdate action to complete when the email domain contains example.com, company.org, or any combination of case, such as EXAMPLE.COM.
```
{
    "Version": "2012-10-17",
    "Statement": [
        {
            "Sid": "AllowConditionKey",
            "Effect": "Allow",
            "Action": [
                "account:StartPrimaryEmailUpdate"
            ],
            "Resource": "*",
            "Condition": {
                "StringEqualsIgnoreCase": {
                    "account:EmailTargetDomain": [
                        "example.com",
                        "company.org"
                    ]
                }
            }
        }
    ]
}
```

To see a list of Account Management condition keys, see Condition keys for Amazon Account Management in the Service Authorization Reference. To learn with which actions and resources you can use a condition key, see Actions defined by Amazon Account Management.

Access control lists in Account 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 with Account Management

Supports ABAC (tags in policies): No

Attribute-based access control (ABAC) is an authorization strategy that defines permissions based on attributes. In Amazon, these attributes are called tags. You can attach tags to IAM entities (users or roles) and to many Amazon resources. Tagging entities and resources is the first step of ABAC. Then you design ABAC policies to allow operations when the principal's tag matches the tag on the resource that they are trying to access.

ABAC is helpful in environments that are growing rapidly and helps with situations where policy management becomes cumbersome.

For Amazon Account Management, tag-based access control is supported only through the account:AccountResourceOrgTags/key-name condition key. The standard aws:ResourceTag/key-name condition key is not supported for APIs in the account namespace.

Example JSON policy using the supported condition key

The following example policy allows access to view contact information for accounts tagged with the key "CostCenter" and either value "12345" or "67890" in your organization.

For more information about ABAC, see Define permissions based on attributes with ABAC authorization and IAM tutorial: Define permissions to access Amazon resources based on tags in the IAM User Guide.

Using temporary credentials with Account Management

Supports temporary credentials: Yes

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

Cross-service principal permissions for Account Management

Supports forward access sessions (FAS): Yes

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

Service roles for Account Management

Supports service roles: No

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 Amazon Web Services service in the IAM User Guide.

Service-linked roles for Account Management

Supports service-linked roles: No

A service-linked role is a type of service role that is linked to an Amazon Web Services service. The service can assume the role to perform an action on your behalf. Service-linked roles appear in your Amazon Web Services account and are owned by the service. An IAM administrator can view, but not edit the permissions for service-linked roles.

For details about creating or managing service-linked roles, see Amazon services that work with IAM. Find a service in the table that includes a Yes in the Service-linked role column. Choose the Yes link to view the service-linked role documentation for that service.
