How AWS User Notifications works with IAM

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

User Notifications Identity-based policies

With IAM identity-based policies, you can specify allowed or denied actions and resources. You can also specify the conditions under which actions are allowed or denied. User Notifications 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.

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 User Notifications use the following prefixes before the action:

For example, to grant someone permission to update notification configurations with the UpdateNotificationConfiguration API operation, you include the notifications:UpdateNotificationConfiguration action in their policy. Policy statements must include either an Action or NotAction element. User Notifications 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": [
      "notifications:action1",
      "notifications:action2"

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

"Action": "notifications:Get*"

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": "*"

For a list of resource types and their ARNs for User Notifications and User Notifications Contacts, see Resources Defined by AWS User Notifications and Resources Defined by AWS User Notifications Contacts in the IAM User Guide. To learn with which actions you can specify the ARN of each resource, see Actions Defined by AWS User Notifications .

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.

User Notifications 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 condition keys for User Notifications and User Notifications Contacts, see Condition Keys for AWS User Notifications and Condition Keys for AWS User Notifications Contacts in the IAM User Guide. To learn with which actions and resources you can use a condition key, see Actions Defined by AWS User Notifications and Actions Defined by AWS User Notifications Contacts.

Examples

To view examples of User Notifications identity-based policies, see AWS User Notifications identity-based policy examples.

Authorization based on User Notifications tags

You can attach tags to User Notifications resources or pass tags in a request to User Notifications. To control access based on tags, you provide tag information in the condition element of a policy using the notifications:ResourceTag/key-name, aws:RequestTag/key-name, or aws:TagKeys condition keys. For more information about tagging User Notifications resources, see Tagging your AWS User Notifications resources.

To view an example identity-based policy for limiting access to a resource based on the tags on that resource, see Viewing User Notifications notification configurations based on tags.

User Notifications IAM roles

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

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.

User Notifications supports service-linked roles. For details about creating or managing User Notifications service-linked roles, see Using Service-Linked Roles for User Notifications.
