Using managed policies for EC2 Image Builder

An AWS managed policy is a standalone policy that is created and administered by AWS. AWS managed policies are designed to provide permissions for many common use cases so that you can start assigning permissions to users, groups, and roles.

Keep in mind that AWS managed policies might not grant least-privilege permissions for your specific use cases because they're available for all AWS customers to use. We recommend that you reduce permissions further by defining customer managed policies that are specific to your use cases.

You cannot change the permissions defined in AWS managed policies. If AWS updates the permissions defined in an AWS managed policy, the update affects all principal identities (users, groups, and roles) that the policy is attached to. AWS is most likely to update an AWS managed policy when a new AWS service is launched or new API operations become available for existing services.

For more information, see AWS managed policies in the IAM User Guide.

AWSImageBuilderFullAccess policy

The AWSImageBuilderFullAccess policy grants full access to Image Builder resources for the role it's attached to, allowing the role to list, describe, create, update, and delete Image Builder resources. The policy also grants targeted permissions to related AWS services that are needed, for example, to verify resources, or to display current resources for the account in the AWS Management Console.

Permissions details

This policy includes the following permissions:

• Image Builder – Administrative access is granted, so that the role can list, describe, create, update, and delete Image Builder resources.

• Amazon EC2 – Access is granted for Amazon EC2 Describe actions that are needed to verify resource existence or get lists of resources belonging to the account.

• IAM – Access is granted to get and use instance profiles whose name contains "imagebuilder", to verify the existence of the Image Builder service-linked role via the iam:GetRole API action, and to create the Image Builder service-linked role.

• License Manager – Access is granted to list license configurations or licenses for a resource.

• Amazon S3 – Access is granted to list buckets belonging to the account, and also Image Builder buckets with "imagebuilder" in their names.

• Amazon SNS – Write permissions are granted to Amazon SNS to verify topic ownership for topics containing "imagebuilder".

AWSImageBuilderReadOnlyAccess policy

The AWSImageBuilderReadOnlyAccess policy provides read-only access to all Image Builder resources. Permissions are granted to verify that the Image Builder service-linked role exists via the iam:GetRole API action.

Permissions details

This policy includes the following permissions:

• Image Builder – Access is granted for read-only access to Image Builder resources.

• IAM – Access is granted to verify the existence of the Image Builder service-linked role via the iam:GetRole API action.

Policy example

The following is an example of the AWSImageBuilderReadOnlyAccess policy.

{
    "Version": "2012-10-17",
    "Statement": [
        {
            "Effect": "Allow",
            "Action": [
                "imagebuilder:Get*",
                "imagebuilder:List*"
            ],

            ],
            "Resource": "arn:aws:iam::*:role/aws-service-role/imagebuilder.amazonaws.com/AWSServiceRoleForImageBuilder"
        }
    ]
}

AWSServiceRoleForImageBuilder policy

The AWSServiceRoleForImageBuilder policy allows Image Builder to call AWS services on your behalf.

Permissions details

This policy is attached to the Image Builder service-linked role when the role is created through Systems Manager. To review specific permissions that are granted, see the policy example in this section. For more information about the Image Builder service-linked role, see Using service-linked roles for EC2 Image Builder.

The policy includes the following permissions:

• CloudWatch Logs – Access is granted to create and upload CloudWatch Logs to any log group whose name starts with /aws/imagebuilder/.

• Amazon EC2 – Access is granted for Image Builder to create images and launch EC2 instances in your account, using related snapshots, volumes, network interfaces, subnets, security groups, license configuration and key pairs as required, as long as the image, instance, and volumes that are being created or used are tagged with CreatedBy: EC2 Image Builder or CreatedBy: EC2 Fast Launch.

  Image Builder can get information about Amazon EC2 images, instance attributes, instance status, the instance types that are available to your account, launch templates, subnets, hosts, and tags on your Amazon EC2 resources.

  Image Builder can update image settings to enable or disable faster launching of Windows instances in your account, where the image is tagged with CreatedBy: EC2 Image Builder.

  Additionally, Image Builder can start, stop, and terminate instances that are running in your account, share Amazon EBS snapshots, create and update images and launch templates, de-register existing images, add tags, and replicate images across accounts that you have granted permissions to via the Ec2ImageBuilderCrossAccountDistributionAccess policy. Image Builder tagging is required for all of these actions, as described previously.

• Amazon ECR – Access is granted for Image Builder to create a repository if needed for container image vulnerability scans, and tag the resources it creates to limit the scope of its operations. Access is also granted for Image Builder to delete the container images that it created for the scans after it takes snapshots of the vulnerabilities.

• EventBridge – Access is granted for Image Builder to create and manage EventBridge rules.

• IAM – Access is granted for Image Builder to pass any role in your account to Amazon EC2, and to VM Import/Export.

• Amazon Inspector – Access is granted for Image Builder to determine when Amazon Inspector completes build instance scans, and to collect findings for images that are configured to allow it.

• AWS KMS – Access is granted for Amazon EBS to encrypt, decrypt, or re-encrypt Amazon EBS volumes. This is crucial to ensure that encrypted volumes work when Image Builder builds an image.

• License Manager – Access is granted for Image Builder to update License Manager specifications via license-manager:UpdateLicenseSpecificationsForResource.

• Amazon SNS – Write permissions are granted for any Amazon SNS topic in your account.

• Systems Manager – Access is granted for Image Builder to list Systems Manager commands and their invocations, inventory entries , describe instance information and automation execution statuses, and get command invocation details. Image Builder can also send automation signals, and stop automation executions for any resource in your account.

  Image Builder is able to issue run command invocations to any instance that is tagged "CreatedBy": "EC2 Image Builder" for the following script files: AWS-RunPowerShellScript, AWS-RunShellScript, or AWSEC2-RunSysprep. Image Builder is able to start an Systems Manager automation execution in your account for automation documents where the name starts with ImageBuilder.

  Image Builder is also able to create or delete State Manager associations for any instance in your account, as long as the association document is AWS-GatherSoftwareInventory, and to create the Systems Manager service-linked role in your account.

• AWS STS – Access is granted for Image Builder to assume roles named EC2ImageBuilderDistributionCrossAccountRole from your account to any account where the Trust policy on the role permits it. This is used for cross-account image distribution.

AWSServiceRoleForImageBuilder – Update to an existing policy	Image Builder made the following changes to the service role to allow Image Builder workflows to collect vulnerability findings for both AMI and ECR container image builds. The new permissions support the CVE detection and reporting feature. Added inspector2:ListCoverage and inspector2:ListFindings to allow Image Builder to determine when Amazon Inspector completes test instance scans, and to collect findings for images that are configured to allow it. Added ecr:CreateRepository, with a requirement for Image Builder to tag the repository with CreatedBy: EC2 Image Builder (tag-on-create). Also added ecr:TagResource (required for tag-on-create) with the same CreatedBy tag constraint, and an additional constraint that requires the repository name to start with image-builder-*. The name constraint prevents the escalation of privileges and prevents changes to repositories that Image Builder didn't create.
