Identity-based policy examples for zonal autoshift

By default, users and roles don't have permission to create or modify Route 53 ARC resources. They also can't perform tasks by using the Amazon Web Services Management Console, Amazon Command Line Interface (Amazon CLI), or Amazon API. To grant users permission to perform actions on the resources that they need, an IAM administrator can create IAM policies. The administrator can then add the IAM policies to roles, and users can assume the roles.

To learn how to create an IAM identity-based policy by using these example JSON policy documents, see Creating IAM policies in the IAM User Guide.

For details about actions and resource types defined by Route 53 ARC, including the format of the ARNs for each of the resource types, see Actions, resources, and condition keys for Amazon Route 53 Application Recovery Controller in the Service Authorization Reference.

Policy best practices

Identity-based policies determine whether someone can create, access, or delete Route 53 ARC resources in your account. These actions can incur costs for your Amazon Web Services account. When you create or edit identity-based policies, follow these guidelines and recommendations:

  • Get started with Amazon managed policies and move toward least-privilege permissions – To get started granting permissions to your users and workloads, use the Amazon managed policies that grant permissions for many common use cases. They are available in your Amazon Web Services account. We recommend that you reduce permissions further by defining Amazon customer managed policies that are specific to your use cases. For more information, see Amazon managed policies or Amazon managed policies for job functions in the IAM User Guide.

  • Apply least-privilege permissions – When you set permissions with IAM policies, grant only the permissions required to perform a task. You do this by defining the actions that can be taken on specific resources under specific conditions, also known as least-privilege permissions. For more information about using IAM to apply permissions, see Policies and permissions in IAM in the IAM User Guide.

  • Use conditions in IAM policies to further restrict access – You can add a condition to your policies to limit access to actions and resources. For example, you can write a policy condition to specify that all requests must be sent using SSL. You can also use conditions to grant access to service actions if they are used through a specific Amazon Web Service, such as Amazon CloudFormation. For more information, see IAM JSON policy elements: Condition in the IAM User Guide.

  • Use IAM Access Analyzer to validate your IAM policies to ensure secure and functional permissions – IAM Access Analyzer validates new and existing policies so that the policies adhere to the IAM policy language (JSON) and IAM best practices. IAM Access Analyzer provides more than 100 policy checks and actionable recommendations to help you author secure and functional policies. For more information, see IAM Access Analyzer policy validation in the IAM User Guide.

  • Require multi-factor authentication (MFA) – If you have a scenario that requires IAM users or a root user in your Amazon Web Services account, turn on MFA for additional security. To require MFA when API operations are called, add MFA conditions to your policies. For more information, see Configuring MFA-protected API access in the IAM User Guide.

For more information about best practices in IAM, see Security best practices in IAM in the IAM User Guide.

Example: Zonal autoshift console access

To access the Amazon Route 53 Application Recovery Controller console, you must have a minimum set of permissions. These permissions must allow you to list and view details about the Route 53 ARC resources in your Amazon Web Services account. If you create an identity-based policy that is more restrictive than the minimum required permissions, the console won't function as intended for entities (users or roles) with that policy.

You don't need to allow minimum console permissions for users that are making calls only to the Amazon CLI or the Amazon API. Instead, allow access to only the actions that match the API operation that they're trying to perform.

To perform some tasks, users must have permission to create the service-linked role that is associated with zonal autoshift in Route 53 ARC. To learn more, see Using the service-linked role for zonal autoshift in Route 53 ARC.

To give users full access to use zonal autoshift in the Amazon Web Services Management Console, attach a policy like the following to the user:

{
    "Version": "2012-10-17",
    "Statement": [
        {
            "Effect": "Allow",
            "Action": [
                   "arc-zonal-shift:ListManagedResources",
                   "arc-zonal-shift:GetManagedResource",
                   "arc-zonal-shift:ListZonalShifts",
                   "arc-zonal-shift:StartZonalShift",
                   "arc-zonal-shift:UpdateZonalShift",
                   "arc-zonal-shift:CancelZonalShift",
                   "arc-zonal-shift:CreatePracticeRunConfiguration",
                   "arc-zonal-shift:DeletePracticeRunConfiguration",
                   "arc-zonal-shift:ListAutoshifts",
                   "arc-zonal-shift:UpdatePracticeRunConfiguration",
                   "arc-zonal-shift:UpdateZonalAutoshiftConfiguration"
             ],
            "Resource": "*"
        },
        {
            "Effect": "Allow",
            "Action": "ec2:DescribeAvailabilityZones",
            "Resource": "*"
        },
        {
            "Effect": "Allow",
            "Action": "cloudwatch:DescribeAlarms",
            "Resource": "*"
        }
    ]
}

Examples: Route 53 ARC API actions

You can use a policy to ensure that a user can use Route 53 ARC API actions for zonal autoshift to configure zonal autoshift so that Amazon shifts away application resource traffic from an Availability Zone, on your behalf, to healthy AZs in the Amazon Web Services Region, to help reduce your time to recovery during events. To provide these permissions, attach a policy that corresponds to the API operations that the user needs to work with, as described below.

To perform some tasks, users must have permissions for the service-linked role that is associated with Route 53 ARC. Permissions needed to create the service-linked role are included in the following example policy. To learn more, see Using the service-linked role for zonal autoshift in Route 53 ARC.

To work with API operations for zonal autoshift, attach a policy such as the following to the user:

{
    "Version": "2012-10-17",
    "Statement": [
        {
            "Effect": "Allow",
            "Action": [		
                   "arc-zonal-shift:ListManagedResources",
                   "arc-zonal-shift:GetManagedResource",
                   "arc-zonal-shift:ListZonalShifts",
                   "arc-zonal-shift:StartZonalShift",
                   "arc-zonal-shift:UpdateZonalShift",
                   "arc-zonal-shift:CancelZonalShift",
                   "arc-zonal-shift:CreatePracticeRunConfiguration",
                   "arc-zonal-shift:DeletePracticeRunConfiguration",
                   "arc-zonal-shift:ListAutoshifts",
                   "arc-zonal-shift:UpdatePracticeRunConfiguration",
                   "arc-zonal-shift:UpdateZonalAutoshiftConfiguration"
             ],
            "Resource": "*"
        },
        {
            "Effect" : "Allow",
            "Action" : [
                    "cloudwatch:DescribeAlarms",
                    "health:DescribeEvents"
            ],
            "Resource" : "*"
        },
        {
            "Effect" : "Allow",
            "Action" : [
                    "arc-zonal-shift:CancelZonalShift",
                    "arc-zonal-shift:GetManagedResource",
                    "arc-zonal-shift:StartZonalShift",
                    "arc-zonal-shift:UpdateZonalShift"
            ],
            "Resource" : "*"
        }
    ]
