<a name="security-iam-readiness"></a>

**Note**  
The readiness check feature in Amazon Application Recovery Controller (ARC) is no longer open to new customers. Existing customers can continue to use the service as normal. For more information, see [Amazon Application Recovery Controller (ARC) readiness check availability change](https://docs.aws.amazon.com/r53recovery/latest/dg/arc-readiness-availability-change.html).

AWS Identity and Access Management (IAM) is an AWS service that helps an administrator securely control access to AWS resources. IAM administrators control who can be *authenticated* (signed in) and *authorized* (have permissions) to use ARC resources. IAM is an AWS service that you can use with no additional charge.
