How AWS HealthImaging works with IAM

Before you use IAM to manage access to HealthImaging, learn what IAM features are available to use with HealthImaging.

To get a high-level view of how HealthImaging 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 HealthImaging

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 HealthImaging

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 HealthImaging

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 HealthImaging actions, see Actions defined by AWS HealthImaging in the Service Authorization Reference.

Policy actions in HealthImaging use the following prefix before the action:

AWS

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

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

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

Policy resources for HealthImaging

Supports policy resources: 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 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 HealthImaging resource types and their ARNs, see Resource types defined by AWS HealthImaging in the Service Authorization Reference. To learn with which actions and resources you can use an ARN, see Actions defined by AWS HealthImaging.

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

Policy condition keys for HealthImaging

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 HealthImaging condition keys, see Condition keys for AWS HealthImaging in the Service Authorization Reference. To learn with which actions and resources you can use a condition key, see Actions defined by AWS HealthImaging.

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

ACLs in HealthImaging

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.

RBAC with HealthImaging

The traditional authorization model used in IAM is called role-based access control (RBAC). RBAC defines permissions based on a person's job function, known outside of AWS as a role. For more information, see Comparing ABAC to the traditional RBAC model in the IAM User Guide.

ABAC with HealthImaging

Supports ABAC (tags in policies): Partial

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 HealthImaging

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.

Cross-service principal permissions for HealthImaging

Supports forward access sessions (FAS): Yes

When you use an IAM user or role to perform actions in AWS, you are considered a principal. Policies grant permissions to a principal. When you use some services, you might perform an action that then triggers another action in a different service. In this case, you must have permissions to perform both actions. To see whether an action requires additional dependent actions in a policy, see Actions, resources, and condition keys for AWS HealthImaging in the Service Authorization Reference.

Service roles for HealthImaging

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.

Service-linked roles for HealthImaging

Supports service-linked roles: No

A service-linked role is a type of service role that is linked to an AWS service. The service can assume the role to perform an action on your behalf. Service-linked roles appear in your AWS 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 AWS 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.
