# Using service-linked roles for Amazon Inspector
<a name="using-service-linked-roles"></a>

Amazon Inspector uses an Amazon Identity and Access Management (IAM) [service-linked role](https://docs.amazonaws.cn/IAM/latest/UserGuide/id_roles_terms-and-concepts.html#iam-term-service-linked-role) named `AWSServiceRoleForAmazonInspector2`. This service-linked role is an IAM role that is linked directly to Amazon Inspector. It is predefined by Amazon Inspector and it includes all the permissions that Amazon Inspector requires to call other Amazon Web Services services on your behalf. 

A service-linked role makes setting up Amazon Inspector easier because you don’t have to manually add the necessary permissions. Amazon Inspector defines the permissions of its service-linked role and, unless defined otherwise, only Amazon Inspector can assume the role. The defined permissions include the trust policy and the permissions policy, and that permissions policy cannot be attached to any other IAM entity.

You must configure permissions to allow an IAM entity (such as a group or role) to create, edit, or delete a service-linked role. For more information, see [Service-linked role permissions](https://docs.amazonaws.cn/IAM/latest/UserGuide/using-service-linked-roles.html#service-linked-role-permissions) in the *IAM User Guide*. You can delete a service-linked role only after deleting its related resources. This protects your Amazon Inspector resources because you can't inadvertently remove permission to access the resources.

For information about other services that support service-linked roles, see [Amazon services that work with IAM](https://docs.amazonaws.cn/IAM/latest/UserGuide/reference_aws-services-that-work-with-iam.html) and look for the services that have **Yes **in the **Service-linked roles** column. Choose a **Yes** with a link to review the service-linked role documentation for that service.

## Creating a service-linked role for Amazon Inspector
<a name="create-slr"></a>

You don't need to manually create a service-linked role. When you activate Amazon Inspector in the Amazon Web Services Management Console, the Amazon CLI, or the Amazon API, Amazon Inspector creates the service-linked role for you. 

## Editing a service-linked role for Amazon Inspector
<a name="edit-slr"></a>

Amazon Inspector does not allow you to edit the `AWSServiceRoleForAmazonInspector2` service-linked role. After a service-linked role is created, you cannot change the name of the role because various entities might reference the role. However, you can edit the description of the role by using IAM. For more information, see [Editing a service-linked role](https://docs.amazonaws.cn/IAM/latest/UserGuide/using-service-linked-roles.html#edit-service-linked-role) in the *IAM User Guide*.

## Deleting a service-linked role for Amazon Inspector

If you no longer need to use Amazon Inspector, we recommend that you delete the `AWSServiceRoleForAmazonInspector2` service-linked role. Before you can delete the role, you must deactivate Amazon Inspector in each Amazon Web Services Region where it's activated. When you deactivate Amazon Inspector, it doesn't delete the role for you. Therefore, if you activate Amazon Inspector again, it can use the existing role. That way you can avoid having an unused entity that's not actively monitored or maintained. However, you must clean up the resources for your service-linked role before you can manually delete it.

If you delete this service-linked role and then need to create it again, you can use the same process to re-create the role in your account. When you activate Amazon Inspector, Amazon Inspector re-creates the service-linked role for you. 

**Note**  
If the Amazon Inspector service is using the role when you try to delete the resources, the deletion might fail. If that happens, wait a few minutes and then try the operation again.

You can use the IAM console, the Amazon CLI, or the Amazon API to delete the `AWSServiceRoleForAmazonInspector2` service-linked role. For more information, see [Deleting a service-linked role](https://docs.amazonaws.cn/IAM/latest/UserGuide/using-service-linked-roles.html#delete-service-linked-role) in the *IAM User Guide*.

If you no longer need to use a feature or service that requires a service-linked role, we recommend that you delete that role. That way you don't have an unused entity that isn't actively monitored or maintained. 

**Important**  
In order to delete the `AWSServiceRoleForAmazonInspector2Agentless` role, you must set your scan mode to agent-based in all Regions where agentless scanning is available.
