This is a security-focused release of the AWS Deployment Framework (ADF) that aims to restrict the default access required and provided by ADF via the least-privilege principle. __Key security enhancements include:__ - Applying IAM best practices by restricting excessive permissions granted to IAM roles and policies used by ADF. - Leveraging new IAM features to further limit access privileges granted by default, reducing the potential attack surface. - Where privileged access is required for specific ADF use cases, the scope and duration of elevated privileges have been minimized to limit the associated risks. By implementing these security improvements, ADF now follows the principle of least privilege, reducing the risk of unauthorized access or privilege-escalation attacks. Please make sure to go through the list of changes breaking changes carefully. As with every release, it is strongly recommended to thoroughly review and test this version of ADF in a non-production environment first. ### Breaking changes #### Security: Confused Deputy Problem Addressed the [Confused Deputy problem](https://docs.aws.amazon.com/IAM/latest/UserGuide/confused-deputy.html) in IAM roles created by ADF to use by the AWS Services. Where supported, the roles are restricted to specific resources via an `aws:SourceArn` condition. If you were using the ADF roles for other resources or use cases not covered by ADF, you might need to patch the Assume Role policies accordingly. #### Security: Cross-Account Access Role and the new Jump Role ADF relies on the privileged Cross-Account Access Role to bootstrap accounts. In the past, ADF used this role for every update and deployment of the bootstrap stacks, as well as account management features. With the release of v4.0, a jump role is introduced to lock-down the usage of the privileged cross-account access role. Part of the bootstrap stack, the `adf-bootstrap-update-deployment-role` is created. This role grants access to perform restricted updates that are frequently performed via the `aws-deployment-framework-bootstrap` pipeline. By default, the jump role is granted access to assume into this update deployment role. A dedicated jump role manager is responsible to grant the jump role access to the cross-account access role for AWS accounts where ADF requires access and the `adf-bootstrap-update-deployment-role` is not available yet. For example, accounts that are newly created only have the cross-account access role to assume into. Same holds for ADF managed accounts that are not updated to the new v4.0 bootstrap stack yet. During the installation/update of ADF, a new parameter enables you to grant the jump role temporary access to the cross-account access role as an privileged escalation path. This parameter is called `GrantOrgWidePrivilegedBootstrapAccessUntil`. By setting this to a date/time in the future you will grant access to the cross-account access role until that date/time. This would be required if you modify ADF itself or the bootstrap stack templates. Changing permissions like the `adf-cloudformation-deployment-role` is possible without relying on the cross-account access role. For most changes deployed via the bootstrap pipeline it does not require elevated privileged access to update. With the above changes, the `aws-deployment-framework-bootstrap` CodeBuild project no longer has unrestricted access to the privileged cross-account role. Starting from version 4.0, access to assume the privileged cross-account access role is restricted and must be obtained through the Jump Role as described above. #### Security: Restricted account management access Account Management is able to access non-protected organization units. Prior to ADF v4.0, the account management process used the privileged cross-account assess role to operate. Hence it could move an account or update the properties of an account that is located in a protected organization unit too. With the release of v4.0, it is only able to move or manage accounts if they are accessible via the Jump Role. The Jump Role is restricted to non-protected organization units only. This enhances the security of ADF, as defining a organization unit as protected will block access to that via the Jump Role accordingly. #### Security: Restricted bootstrapping of management account The `adf-global-base-adf-build` stack in the management account was initially deployed to facilitate bootstrap access to the management account. It accomplished this by creating a cross-account access role with limited permissions in the management account ahead of the bootstrapping process. ADF created this role as it is not provisioned by AWS Organizations or AWS Control Tower in the management account itself. However, ADF required some level of access to deploy the necessary bootstrap stacks when needed. It is important to note that deploying this role and bootstrapping the management account introduces a potential risk. A pipeline created via a deployment map could target the management account and create resources within it, which may have unintended consequences. To mitigate the potential risk, it is recommended to implement strict least-privilege policies and apply permission boundaries to protect the management account. Additionally, thoroughly reviewing all deployment map changes is crucial to ensure no unintended access is granted to the management account. With the release of ADF v4.0, the `adf-global-base-adf-build` stack is removed and its resources are moved to the main ADF CloudFormation template. These resources will only get deployed if the new `AllowBootstrappingOfManagementAccount` parameter is set to `Yes`. By default it will not allow bootstrapping of the management account. #### Security: Restricted bootstrapping of deployment account Considering the sensitive workloads that run in the deployment account, it is important to limit the permissions granted for pipelines to deploy to the deployment account itself. You should consider the deployment account a production account. It is recommended to apply the least-privilege principle and only allow pipelines to deploy resources that are required in the deployment account. Follow these steps after the changes introduced by the ADF v4.0 release are applied in the main branch of the `aws-deployment-framework-bootstrap` repository. Please take this moment to review the following: * Navigate to the `adf-boostrap/deployment` folder in that repository. * Check if it contains a `global-iam.yml` file: * If it does __not__ contain a `global-iam.yml` file yet, please ensure you copy the `example-global-iam.yml` file in that directory. * If it does, please compare it against the `example-global-iam.yml` file in that directory. * Apply the least-privilege principle on the permissions you grant in the deployment account. #### Security: Shared Modules Bucket ADF uses the Shared Modules Bucket as hosted in the management account in the main deployment region to share artifacts from the `aws-deployment-framework-bootstrap` repository. The breaking change enforces all objects to be owned by the bucket owner from v4.0 onward. #### Security: ADF Role policy restrictions With the v4.0 release, all ADF roles and policies were reviewed, applying the latest best-practices and granting access to ADF resources only where required. This review also includes the roles that were used by the pipelines generated by ADF. Please be aware of the changes made to the following roles: ##### adf-codecommit-role The `adf-codecommit-role` no longer grants read/write access to all buckets. It only grants access to the buckets created and managed by ADF where it needed to. Please grant access accordingly if you use custom S3 buckets or need to copy from an S3 bucket in an ADF-generated pipeline. ##### adf-codebuild-role The `adf-codebuild-role` can only be used by CodeBuild projects in the main deployment region. ADF did not allow running CodeBuild projects in other regions before. But in case you manually configured the role in a project in a different region it will fail to launch. The `adf-codebuild-role` is no longer allowed to assume any IAM Role in the target accounts if those roles would grant access in the Assume Role Policy Document. The `adf-codebuild-role` is restricted to assume only the `adf-readonly-automation-role` roles in the target accounts. And, in the case that the Terraform ADF Extension is enabled, it is allowed to assume the `adf-terraform-role` too. It is therefore not allowed to assume the `adf-cloudformation-deployment-role` any longer. If you were deploying with `cdk deploy` into target accounts from an ADF pipeline you will need to specifically grant the `adf-codebuild-role` access to assume the `adf-cloudformation-deployment-role`. However, we strongly recommend you synthesize the templates instead and let AWS CloudFormation do the deployment for you. For Terraform support, CodeBuild was granted access to the `adf-tflocktable` table in release v3.2.0. This access is restricted to only grant read/write access to that table if the Terraform extension is enabled. Please bear in mind that if you enable Terraform access the first time, you will need to use the `GrantOrgWidePrivilegedBootstrapAccessUntil` parameter if ADF v4.0 bootstrapped to accounts before. As this operation requires privileged access. The `adf-codebuild-role` is allowed to assume into the `adf-terraform-role` if the Terraform extension is enabled. As written in the docs, the `adf-terraform-role` is configured in the `global-iam.yml` file. This role is commented out by default. When you define this role, it is important to make sure to grant it [least-privilege access](https://docs.aws.amazon.com/IAM/latest/UserGuide/best-practices.html#grant-least-privilege) only. ##### adf-cloudformation-role The `adf-cloudformation-role` is no longer assumable by CloudFormation. This role is used by CodePipeline to orchestrate various deployment actions across accounts. For example, CodeDeploy, S3, and obviously the CloudFormation actions. For CloudFormation, it would instruct the service to use the CloudFormation Deployment role for the actual deployment. The CloudFormation deployment role is the role that is assumed by the CloudFormation service. This change should not impact you, unless you use this role in relation with CloudFormation that is not managed by ADF. With v4.0, the `adf-cloudformation-role` is only allowed to pass the CloudFormation Deployment role to CloudFormation and no other roles to other services. If you were/want to make use of a custom CloudFormation deployment role for specific pipelines, you need to make sure that the `adf-cloudformation-role` is allowed to perform an `iam:PassRole` action with the given role. It is recommended to limit this to be passed to the CloudFormation service only. You can find an example of this in the `adf-bootstrap/deployment/global.yml` file where it allows the CloudFormation role to perform `iam:PassRole` with the `adf-cloudformation-deployment-role`. When required, please grant this access in the `adf-bootstrap/deployment/global-iam.yml` file in the `aws-deployment-framework-bootstrap` repository. Additionally, the `adf-cloudformation-role` is not allowed to access S3 buckets except the ADF buckets it needs to transfer pipeline assets to CloudFormation. ##### adf-codepipeline-role The `adf-codepipeline-role` is no longer assumable by CloudFormation, CodeDeploy, and S3. The role itself was not passed to any of these services by ADF. If you relied on the permissions that were removed, feel free to extend the role permissions via the `global-iam.yml` stack. #### Security: Restricted access to ADF-managed S3 buckets only With v4.0, access is restricted to ADF-managed S3 buckets only. If a pipeline used the S3 source or deployment provider, it will require the required access to those buckets. Please add the required access to the `global-iam.yml` bootstrap stack in the OU where it is hosted. Grant read access to the `adf-codecommit-role` for S3 source buckets. Grant write access to the `adf-cloudformation-role` for S3 buckets an ADF pipeline deploys to. #### Security: Bootstrap stack no longer named after organization unit The global and regional bootstrap stacks are renamed to `adf-global-base-bootstrap` and `adf-regional-base-bootstrap` respectively. In prior releases of ADF, the name ended with the organization unit name. As a result, an account could not move from one organization unit to another without first removing the bootstrap stacks. Additionally, it made writing IAM policies and SCPs harder in a least-privilege way. When ADF v4.0 is installed, the legacy stacks will get removed by the `aws-deployment-framework-bootstrap` pipeline automatically. Shortly after removal, it will deploy the new bootstrap stacks. With v4.0, accounts can move from one organization unit to another, without requiring the removal of the ADF bootstrap stacks. #### Security: KMS Encryption required on Deployment Account Pipeline Buckets The deployment account pipeline buckets only accepts KMS Encrypted objects from v4.0 onward. Ensuring that all objects are encrypted with the same KMS Key. Before, some objects used KMS encryption while others did not. The bucket policy now requires all objects to be encrypted via the KMS key. All ADF components have been adjusted to upload with this key. If, however, you copy files from systems that are not managed by ADF, you will need to adjust these to encrypt the objects with the KMS key as well. #### Security: TLS Encryption required on all ADF-managed buckets S3 Buckets created by ADF will require TLS 1.2 or later. All actions that occur on these buckets with older TLS versions will be denied via the bucket policies that these buckets received. #### New installer The dependencies that are bundled by the move to the AWS Cloud Development Kit (CDK) v2 increased the deployment size of ADF. Unfortunately it increased the deployment size beyond the limit that is supported by the Serverless Application Repository (SAR). Hence a new installation mechanism is required. Please read the [installation instructions](https://github.com/awslabs/aws-deployment-framework/blob/master/docs/installation-guide.md) carefully. In case you are upgrading an existing installation of ADF, please consider following the [upgrade steps as defined in the admin guide](https://github.com/awslabs/aws-deployment-framework/blob/master/docs/admin-guide.md#updating-between-versions). #### CDK v2 ADF v4.0 is built on the AWS Cloud Development Kit (CDK) v2. Which is an upgrade to CDK v1 that ADF relied on before. For most end-users, this change would not have an immediate impact. If, however, you made customizations to ADF it might require you to upgrade these customizations to CDK v2 as well. #### CodeBuild default image As written in the [CodeBuild provider docs](./docs/providers-guide.md#properties-3), it is a best-practice to define the exact CodeBuild container image you would like to use for each pipeline. However, in case you rely on the default, in prior ADF releases it would default to `UBUNTU_14_04_PYTHON_3_7_1`. This container image is no longer supported. With ADF v4.0, the new default is `STANDARD_7_0`. Also referred to as: `aws/codebuild/standard:7.0`. #### ADF Renaming of Roles ADF v4.0 changes most of the roles that it relies on. The reason for this change is to make it easier to secure ADF with Service Control Policies and IAM permission boundaries. Where applicable, the roles received a new prefix. This makes it easier to identify what part of ADF relies on those roles and whom should have access to assume the role or modify it. | Previous prefix | Previous name | New prefix | New name | |------------------|---------------------------------------------------------------------|----------------------------|---------------------------------------------------------------| | / | ${CrossAccountAccessRoleName}-readonly | /adf/organizations/ | adf-organizations-readonly | | / | adf-update-cross-account-access-role | /adf/bootstrap/ | adf-update-cross-account-access | | /adf-automation/ | adf-create-repository-role | /adf/pipeline-management/ | adf-pipeline-management-create-repository | | /adf-automation/ | adf-pipeline-provisioner-generate-inputs | /adf/pipeline-management/ | adf-pipeline-management-generate-inputs | | /adf-automation/ | adf-pipeline-create-update-rule | /adf/pipeline-management/ | adf-pipeline-management-create-update-rule | | / | adf-event-rule-${AWS::AccountId}-${DeploymentAccountId}-EventRole-* | /adf/cross-account-events/ | adf-cc-event-from-${AWS::AccountId}-to-${DeploymentAccountId} | |------------------|---------------------------------------------------------------------|----------------------------|---------------------------------------------------------------| #### ADF Renaming of Resources | Type | Previous name | New name | |--------------|-----------------------------------------------|--------------------------------------------------------| | StateMachine | EnableCrossAccountAccess | adf-bootstrap-enable-cross-account | | StateMachine | ADFPipelineManagementStateMachine | adf-pipeline-management | | StateMachine | PipelineDeletionStateMachine-* | adf-pipeline-management-delete-outdated | | Lambda | DeploymentMapProcessorFunction | adf-pipeline-management-deployment-map-processor | | Lambda | ADFPipelineCreateOrUpdateRuleFunction | adf-pipeline-management-create-update-rule | | Lambda | ADFPipelineCreateRepositoryFunction | adf-pipeline-management-create-repository | | Lambda | ADFPipelineGenerateInputsFunction | adf-pipeline-management-generate-pipeline-inputs | | Lambda | ADFPipelineStoreDefinitionFunction | adf-pipeline-management-store-pipeline-definition | | Lambda | ADFPipelineIdentifyOutOfDatePipelinesFunction | adf-pipeline-management-identify-out-of-date-pipelines | |--------------|-----------------------------------------------|--------------------------------------------------------| #### ADF Parameters in AWS Systems Manager Parameter Store Some of the parameters stored by ADF in AWS Systems Manager Parameter Store were located at the root of the Parameter Store. This made it hard to maintain and restrict access to the limited set of ADF specific parameters. With ADF v4.0, the parameters used by ADF are located under the `/adf/` prefix. For example, `/adf/deployment_account_id`. The `global-iam.yml` bootstrap stack templates get copied from their `example-global-iam.yml` counterparts. When this was copied in v3.2.0, the default path for the `deployment_account_id` parameter should be updated to `/adf/deployment_account_id`. Please apply this new default value to the CloudFormation templates accordingly. If you forget to do this, the stack deployment of the `adf-global-base-iam` stack might fail with a failure stating that it does not have permission to fetch the `deployment_account_id` parameter. The error you run into if the parameter path is not updated: > An error occurred (ValidationError) when calling the CreateChangeSet > operation: User: > arn:aws:sts::111111111111:assumed-role/${CrossAccountAccessRoleName}/base_update > is not authorized to perform: ssm:GetParameters on resource: > arn:aws:ssm:${deployment_region}:111111111111:parameter/deployment_account_id > because no identity-based policy allows the ssm:GetParameters action > (Service: AWSSimpleSystemsManagement; Status Code: 400; > Error Code: AccessDeniedException; Request ID: xxx). If an application or customization to ADF relies on one of these parameters they will need to be updated to include this prefix. Unless the application code relies on ADF's ParameterStore class, in that case it will automatically prefix the `/adf/` to all parameters read or written. With the changes in the IAM policies, ADF's access is restricted to the `/adf/` prefix. This, unfortunately implies that old parameters are not deleted when you update your installation of ADF. There is no cost associated to these parameters, so you can leave them as is. Feel free to delete the old parameters. The parameters that are managed by ADF that got their path changed are: For the __management account__, in the __AWS Organizations region__ (`us-east-1`, or `us-gov-west-1`): | Old Parameter Path | New Parameter Path | |------------------------------|----------------------------------| | `/adf_log_level` | `/adf/adf_log_level` | | `/adf_version` | `/adf/adf_version` | | `/bucket_name` | `/adf/bucket_name` | | `/confit` | `/adf/config` | | `/cross_account_access_role` | `/adf/cross_account_access_role` | | `/deployment_account_id` | `/adf/deployment_account_id` | | `/deployment_account_region` | `/adf/deployment_account_region` | | `/kms_arn` | `/adf/kms_arn` | | `/notification_channel` | `/adf/notification_channel` | | `/organization_id` | `/adf/organization_id` | | `/protected` | `/adf/protected` | | `/scp` | `/adf/scp` | | `/shared_modules_bucket` | `/adf/shared_modules_bucket` | | `/tagging-policy` | `/adf/tagging_policy` | | `/target_regions` | `/adf/target_regions` | For the __management account__, in __other ADF regions__: | Old Parameter Path | New Parameter Path | |------------------------------|----------------------------------| | `/adf_version` | `/adf/adf_version` | | `/bucket_name` | `/adf/bucket_name` | | `/cross_account_access_role` | `/adf/cross_account_access_role` | | `/deployment_account_id` | `/adf/deployment_account_id` | | `/kms_arn` | `/adf/kms_arn` | For the __deployment account__, in __the deployment region__: | Old Parameter Path | New Parameter Path | |------------------------------|-------------------------------------| | `/adf_log_level` | `/adf/adf_log_level` | | `/adf_version` | `/adf/adf_version` | | `/auto_create_repositories` | `/adf/scm/auto_create_repositories` | | `/cross_account_access_role` | `/adf/cross_account_access_role` | | `/default_scm_branch` | `/adf/scm//default_scm_branch` | | `/deployment_account_bucket` | `/adf/shared_modules_bucket` | | `/master_account_id` | `/adf/management_account_id` | | `/notification_endpoint` | `/adf/notification_endpoint` | | `/notification_type` | `/adf/notification_type` | | `/organization_id` | `/adf/organization_id` | For the __deployment account__, in __other ADF regions__: | Old Parameter Path | New Parameter Path | |------------------------------|----------------------------------| | `/adf_log_level` | `/adf/adf_log_level` | | `/adf_version` | `/adf/adf_version` | | `/cross_account_access_role` | `/adf/cross_account_access_role` | | `/deployment_account_bucket` | `/adf/shared_modules_bucket` | | `/master_account_id` | `/adf/management_account_id` | | `/notification_endpoint` | `/adf/notification_endpoint` | | `/notification_type` | `/adf/notification_type` | | `/organization_id` | `/adf/organization_id` | For a __target account__, in __each ADF region__: | Old Parameter Path | New Parameter Path | |--------------------------|------------------------------| | `/bucket_name` | `/adf/bucket_name` | | `/deployment_account_id` | `/adf/deployment_account_id` | | `/kms_arn` | `/adf/kms_arn` | #### AWS CodeStar Connections OAuth Token support dropped ADF v4.0 discontinued the support for the OAuth Token stored in SSM Parameter Store. As this method is not advised to be used by CodePipeline, and might leave the OAuth Token accessible to other users of the deployment account. As this is not a security best practice, ADF v4.0 no longer supports it. To upgrade, please read the [Administrator Guide on Using AWS CodeConnections for Bitbucket, GitHub, or GitLab](./docs/admin-guide.md#using-aws-codeconnections-for-bitbucket-github-github-enterprise-or-gitlab). #### AWS CodeStar Connections changed to AWS CodeConnections The AWS CodeStar Connection service [changed its name to AWS CodeConnections](https://docs.aws.amazon.com/dtconsole/latest/userguide/rename.html). If you configured a CodeStar Connection before, you can continue to use that. You do not need to update the CodeStar policy as defined in the `aws-deployment-framework-bootstrap/adf-bootstrap/deployment/global-iam.yml` stack. However, please update the pipeline definitions in your deployment map files. The changes you need to make are renaming the source provider from `codestar` to `codeconnections`. Also update the `codestar_connection_path` source property to `codeconnections_param_path`. Both of these changes can be seen in the following example: ```yaml pipelines: - name: sample-vpc default_providers: source: # provider: codestar provider: codeconnections properties: # codestar_connection_path: /adf/my_connection_arn_param codeconnections_param_path: /adf/my_connection_arn_param ``` If you are upgrading from the GitHub OAuth token or otherwise require a new source code connection, please proceed with the AWS CodeConnections configuration as defined in the [Admin Guide - Using AWS CodeConnections for Bitbucket, GitHub, or GitLab](./docs/admin-guide.md#using-aws-codeconnections-for-bitbucket-github-or-gitlab). ### Features - Update CDK from v1 to v2 (#619), by @pergardebrink, resolves #503, #614, and #617. -

The dependencies that go with it, unfortunately increased the deployment size beyond the limit that is supported by the Serverless Application Repository.
