# Security in AWS CodeBuild
Cloud security at AWS is the highest priority. As an AWS customer, you benefit from data centers and network architectures that are built to meet the requirements of the most security-sensitive organizations.
Security is a shared responsibility between AWS and you. The [shared responsibility model](https://aws.amazon.com/compliance/shared-responsibility-model/) describes this as security *of* the cloud and security *in* the cloud:
+ **Security of the cloud** – AWS is responsible for protecting the infrastructure that runs AWS services in the AWS Cloud. AWS also provides you with services that you can use securely. Third-party auditors regularly test and verify the effectiveness of our security as part of the [AWS Compliance Programs](https://aws.amazon.com/compliance/programs/). To learn about the compliance programs that apply to AWS CodeBuild, see [AWS Services in Scope by Compliance Program](https://aws.amazon.com/compliance/services-in-scope/).
+ **Security in the cloud** – Your responsibility is determined by the AWS service that you use. You are also responsible for other factors including the sensitivity of your data, your company's requirements, and applicable laws and regulations.
This documentation helps you understand how to apply the shared responsibility model when using CodeBuild. The following topics show you how to configure CodeBuild to meet your security and compliance objectives. You also learn how to use other AWS services that help you to monitor and secure your CodeBuild resources.

# Data protection in AWS CodeBuild
The AWS [shared responsibility model](https://aws.amazon.com/compliance/shared-responsibility-model/) applies to data protection in AWS CodeBuild. As described in this model, AWS is responsible for protecting the global infrastructure that runs all of the AWS Cloud. You are responsible for maintaining control over your content that is hosted on this infrastructure. You are also responsible for the security configuration and management tasks for the AWS services that you use. For more information about data privacy, see the [Data Privacy FAQ](https://aws.amazon.com/compliance/data-privacy-faq/). For information about data protection in Europe, see the [AWS Shared Responsibility Model and GDPR](https://aws.amazon.com/blogs/security/the-aws-shared-responsibility-model-and-gdpr/) blog post on the *AWS Security Blog*.
For data protection purposes, we recommend that you protect AWS account credentials and set up individual users with AWS IAM Identity Center or AWS Identity and Access Management (IAM). That way, each user is given only the permissions necessary to fulfill their job duties. We also recommend that you secure your data in the following ways:
+ Use multi-factor authentication (MFA) with each account.
+ Use SSL/TLS to communicate with AWS resources. We require TLS 1.2 and recommend TLS 1.3.
+ Set up API and user activity logging with AWS CloudTrail. For information about using CloudTrail trails to capture AWS activities, see [Working with CloudTrail trails](https://docs.aws.amazon.com/awscloudtrail/latest/userguide/cloudtrail-trails.html) in the *AWS CloudTrail User Guide*.
+ Use AWS encryption solutions, along with all default security controls within AWS services.
+ Use advanced managed security services such as Amazon Macie, which assists in discovering and securing sensitive data that is stored in Amazon S3.
+ If you require FIPS 140-3 validated cryptographic modules when accessing AWS through a command line interface or an API, use a FIPS endpoint. For more information about the available FIPS endpoints, see [Federal Information Processing Standard (FIPS) 140-3](https://aws.amazon.com/compliance/fips/).
We strongly recommend that you never put confidential or sensitive information, such as your customers' email addresses, into tags or free-form text fields such as a **Name** field. This includes when you work with CodeBuild or other AWS services using the console, API, AWS CLI, or AWS SDKs. Any data that you enter into tags or free-form text fields used for names may be used for billing or diagnostic logs. If you provide a URL to an external server, we strongly recommend that you do not include credentials information in the URL to validate your request to that server.
To protect sensitive information, the following are hidden in CodeBuild logs:
+ Strings specified using the Parameter Store in CodeBuild project environment variables or the buildspec `env/parameter-store` section. For more information, see [Systems Manager Parameter Store](https://docs.aws.amazon.com/systems-manager/latest/userguide/systems-manager-paramstore.html) and [Systems Manager Parameter Store console walkthrough](https://docs.aws.amazon.com/systems-manager/latest/userguide/sysman-paramstore-walk.html#sysman-paramstore-console) in the *Amazon EC2 Systems Manager User Guide*.
+ Strings specified using AWS Secrets Manager in CodeBuild project environment variables or the buildspec `env/secrets-manager` section. For more information, see [Key management](security-key-management.md).
For more information about data protection, see the [AWS shared responsibility model and GDPR](https://aws.amazon.com/blogs/security/the-aws-shared-responsibility-model-and-gdpr/) blog post on the *AWS Security Blog*.

# Data encryption
Encryption is an important part of CodeBuild security. Some encryption, such as for data in-transit, is provided by default and does not require you to do anything. Other encryption, such as for data at-rest, you can configure when you create your project or build.
+ **Encryption of data at-rest** - Build artifacts, such as a cache, logs, exported raw test report data files, and build results, are encrypted by default using AWS managed keys. If you do not want to use these KMS keys, you must create and configure a customer managed key. For more information [Creating KMS Keys](https://docs.aws.amazon.com/kms/latest/developerguide/create-keys.html) and [AWS Key Management Service concepts](https://docs.aws.amazon.com/kms/latest/developerguide/concepts.html) in the *AWS Key Management Service User Guide*.
+ You can store the identifier of the AWS KMS key that CodeBuild uses to encrypt the build output artifact in the `CODEBUILD_KMS_KEY_ID` environment variable. For more information, see [Environment variables in build environments](build-env-ref-env-vars.md)
+ You can specify a customer managed key when you create a build project. For more information, see [Set the Encryption Key Using the Console](create-project.md#encryptionkey-console) and [Set the encryption key using the CLI](create-project.md#cli.encryptionkey).
The Amazon Elastic Block Store volumes of your build fleet are encrypted by default using AWS managed keys.
+ **Encryption of data in-transit** - All communication between customers and CodeBuild and between CodeBuild and its downstream dependencies is protected using TLS connections that are signed using the Signature Version 4 signing process. All CodeBuild endpoints use SHA-256 certificates that are managed by AWS Private Certificate Authority. For more information, see [Signature Version 4 signing process](https://docs.aws.amazon.com/general/latest/gr/signature-version-4.html) and [What is ACM PCA](https://docs.aws.amazon.com/privateca/latest/userguide/).
+ **Build artifact encryption** - The CodeBuild service role associated with the build project requires access to a KMS key in order to encrypt its build output artifacts. By default, CodeBuild uses an AWS managed key for Amazon S3 in your AWS account. If you do not want to use this AWS managed key, you must create and configure a customer managed key. For more information, see [Encrypt build outputs](setting-up-kms.md) and [Creating keys](https://docs.aws.amazon.com/kms/latest/developerguide/create-keys.html) in the *AWS KMS Developer Guide*.
# Key management
You can protect your content from unauthorized use through encryption. Store your encryption keys in AWS Secrets Manager, and then give the CodeBuild service role associated with the build project permission to obtain the encryption keys from your Secrets Manager account. For more information, see [Encrypt build outputs using a customer managed key](setting-up-kms.md), [Create a build project in AWS CodeBuild](create-project.md), [Run AWS CodeBuild builds manually](run-build.md), and [Tutorial: Storing and retrieving a secret](https://docs.aws.amazon.com/secretsmanager/latest/userguide/tutorials_basic.html).
Use the `CODEBUILD_KMS_KEY_ID` environment variable in a build command to obtain the AWS KMS key identifier. For more information, see [Environment variables in build environments](build-env-ref-env-vars.md).
You can use Secrets Manager to protect credentials to a private registry that stores a Docker image used for your runtime environment. For more information, see [Private registry with AWS Secrets Manager sample for CodeBuild](sample-private-registry.md).
# Traffic privacy
You can improve the security of your builds by configuring CodeBuild to use an interface VPC endpoint. To do this, you do not need an internet gateway, NAT device, or virtual private gateway. It also is not required to configure PrivateLink, though it is recommended. For more information, see [Use VPC endpoints](use-vpc-endpoints-with-codebuild.md). For more information about PrivateLink and VPC endpoints, see [AWS PrivateLink](https://aws.amazon.com/privatelink/) and [Accessing AWS services through PrivateLink](https://docs.aws.amazon.com/vpc/latest/userguide/VPC_Introduction.html#what-is-privatelink).
# Identity and access management in AWS CodeBuild
Access to AWS CodeBuild requires credentials. Those credentials must have permissions to access AWS resources, such as storing and retrieving build artifacts in S3 buckets and viewing Amazon CloudWatch Logs for builds. The following sections describe how you can use [AWS Identity and Access Management](https://docs.aws.amazon.com/IAM/latest/UserGuide/introduction.html) (IAM) and CodeBuild to help secure access to your resources:
# Overview of managing access permissions to your AWS CodeBuild resources
Every AWS resource is owned by an AWS account, and permissions to create or access a resource are governed by permissions policies. An account administrator can attach permissions policies to IAM identities (that is, users, groups, and roles).
**Note**
An account administrator (or administrator user) is a user with administrator privileges. For more information, see [IAM Best Practices](https://docs.aws.amazon.com/IAM/latest/UserGuide/best-practices.html) in the *IAM User Guide*.
When you grant permissions, you decide who is getting the permissions, the resources they can access, and the actions that can be performed on those resources.

+ [Understanding resource ownership](#understanding-resource-ownership)
+ [Managing access to resources](#managing-access-resources)
+ [Specifying policy elements: Actions, effects, and principals](#actions-effects-principals)
## AWS CodeBuild resources and operations
In AWS CodeBuild, the primary resource is a build project. In a policy, you use an Amazon Resource Name (ARN) to identify the resource the policy applies to. Builds are also resources and have ARNs associated with them. For more information, see [Amazon Resource Names (ARN) and AWS Service Namespaces](https://docs.aws.amazon.com/general/latest/gr/aws-arns-and-namespaces.html) in the *Amazon Web Services General Reference*.
| Resource type | ARN format |
| --- | --- |
| Build project | `arn:aws:codebuild:region-ID:account-ID:project/project-name` |
| Build | `arn:aws:codebuild:region-ID:account-ID:build/build-ID` |
| Report group | arn:aws:codebuild:region-ID:account-ID:report-group/report-group-name |
| Report | arn:aws:codebuild:region-ID:account-ID:report/report-ID |
| Fleet | `arn:aws:codebuild:region-ID:account-ID:fleet/fleet-ID` |
| All CodeBuild resources | `arn:aws:codebuild:*` |
| All CodeBuild resources owned by the specified account in the specified AWS Region | `arn:aws:codebuild:region-ID:account-ID:*` |
**Important**
When using the reserved capacity feature, data cached on fleet instances, including source files, Docker layers, and cached directories specified in the buildspec, can be accessible to other projects within the same account. This is by design and allows projects within the same account to share fleet instances.
**Note**
Most AWS services treat a colon (:) or a forward slash (/) as the same character in ARNs. However, CodeBuild uses an exact match in resource patterns and rules. Be sure to use the correct characters when you create event patterns so that they match the ARN syntax in the resource.
For example, you can indicate a specific build project (*myBuildProject*) in your statement using its ARN as follows:
```
"Resource": "arn:aws:codebuild:us-east-2:123456789012:project/myBuildProject"
```
To specify all resources, or if an API action does not support ARNs, use the wildcard character (\$1) in the `Resource` element as follows:
```
"Resource": "*"
```
Some CodeBuild API actions accept multiple resources (for example, `BatchGetProjects`). To specify multiple resources in a single statement, separate their ARNs with commas, as follows:
```
"Resource": [
"arn:aws:codebuild:us-east-2:123456789012:project/myBuildProject",
"arn:aws:codebuild:us-east-2:123456789012:project/myOtherBuildProject"
]
```
CodeBuild provides a set of operations to work with the CodeBuild resources. For a list, see [AWS CodeBuild permissions reference](auth-and-access-control-permissions-reference.md).
## Understanding resource ownership
The AWS account owns the resources that are created in the account, regardless of who created the resources. Specifically, the resource owner is the AWS account of the [principal entity](https://docs.aws.amazon.com/IAM/latest/UserGuide/id_roles_terms-and-concepts.html) (that is, the root account, an user, or an IAM role) that authenticates the resource creation request. The following examples illustrate how this works:
+ If you use the root account credentials of your AWS account to create a rule, your AWS account is the owner of the CodeBuild resource.
+ If you create an user in your AWS account and grant permissions to create CodeBuild resources to that user, the user can create CodeBuild resources. However, your AWS account, to which the user belongs, owns the CodeBuild resources.
+ If you create an IAM role in your AWS account with permissions to create CodeBuild resources, anyone who can assume the role can create CodeBuild resources. Your AWS account, to which the role belongs, owns the CodeBuild resources.
## Managing access to resources
A permissions policy describes who has access to which resources.
**Note**
This section discusses the use of IAM in AWS CodeBuild. It doesn't provide detailed information about the IAM service. For complete IAM documentation, see [What Is IAM?](https://docs.aws.amazon.com/IAM/latest/UserGuide/introduction.html) in the *IAM User Guide*. For information about IAM policy syntax and descriptions, see [AWS IAM Policy Reference](https://docs.aws.amazon.com/IAM/latest/UserGuide/reference_policies.html) in the *IAM User Guide*.
Policies attached to an IAM identity are referred to as identity-based policies (IAM policies). Policies attached to a resource are referred to as resource-based policies. CodeBuild supports identity-based policies, and resource-based policies for certain read only APIs for the purpose of cross-account resource sharing.
### Secure access to S3 buckets
We strongly recommend that you include the following permissions in your IAM role to verify the S3 bucket associated with your CodeBuild project is owned by you or someone you trust. These permissions are not included in AWS managed policies and roles. You must add them yourself.
+ `s3:GetBucketAcl`
+ `s3:GetBucketLocation`
If the owner of an S3 bucket used by your project changes, you must verify you still own the bucket and update permissions in your IAM role if not. For more information, see [Allow users to interact with CodeBuild](setting-up-service-permissions-group.md) and [Allow CodeBuild to interact with other AWS services](setting-up-service-role.md).
## Specifying policy elements: Actions, effects, and principals
For each AWS CodeBuild resource, the service defines a set of API operations. To grant permissions for these API operations, CodeBuild defines a set of actions that you can specify in a policy. Some API operations can require permissions for more than one action in order to perform the API operation. For more information, see [AWS CodeBuild resources and operations](#arn-formats) and [AWS CodeBuild permissions reference](auth-and-access-control-permissions-reference.md).
The following are the basic policy elements:
+ **Resource** – You use an Amazon Resource Name (ARN) to identify the resource that the policy applies to.
+ **Action** – You use action keywords to identify resource operations you want to allow or deny. For example, the `codebuild:CreateProject` permission gives the user permissions to perform the `CreateProject` operation.
+ **Effect** – You specify the effect, either allow or deny, when the user requests the action. If you don't explicitly grant access to (allow) a resource, access is implicitly denied. You can also explicitly deny access to a resource. You might do this to make sure a user cannot access a resource, even if a different policy grants access.
+ **Principal** – In identity-based policies (IAM policies), the user the policy is attached to is the implicit principal. For resource-based policies, you specify the user, account, service, or other entity that you want to receive permissions.
To learn more about IAM policy syntax and descriptions, see [AWS IAM Policy Reference](https://docs.aws.amazon.com/IAM/latest/UserGuide/reference_policies.html) in the *IAM User Guide*.
For a table showing all of the CodeBuild API actions and the resources they apply to, see the [AWS CodeBuild permissions reference](auth-and-access-control-permissions-reference.md).
# Using identity-based policies for AWS CodeBuild
This topic provides examples of identity-based policies that demonstrate how an account administrator can attach permissions policies to IAM identities (that is, users, groups, and roles) and thereby grant permissions to perform operations on AWS CodeBuild resources.
**Important**
We recommend that you first review the introductory topics that explain the basic concepts and options available to manage access to your CodeBuild resources. For more information, see [Overview of managing access permissions to your AWS CodeBuild resources](auth-and-access-control-iam-access-control-identity-based.md).
**Topics**
+ [Permissions required to use the AWS CodeBuild console](#console-permissions)
+ [Permissions required for AWS CodeBuild to connect to Amazon Elastic Container Registry](#ecr-policies)
+ [Permissions required for the AWS CodeBuild console to connect to source providers](#console-policies)

+ [CodeBuild managed policies and notifications](#notifications-permissions)
+ [CodeBuild updates to AWS managed policies](#security-iam-awsmanpol-updates)
+ [Customer-managed policy examples](#customer-managed-policies)
The following shows an example of a permissions policy that allows a user to get information about build projects only in the `us-east-2` region for account `123456789012` for any build project that starts with the name `my`:
------
#### [ JSON ]
****
```
{
"Version":"2012-10-17",
"Statement": [
{
"Effect": "Allow",
"Action": "codebuild:BatchGetProjects",
"Resource": "arn:aws:codebuild:us-east-2:111122223333:project/my*"
}
]
}
```
------
## Permissions required to use the AWS CodeBuild console
A user who uses the AWS CodeBuild console must have a minimum set of permissions that allows the user to describe other AWS resources for the AWS account. You must have permissions from the following services:
+ AWS CodeBuild
+ Amazon CloudWatch
+ CodeCommit (if you are storing your source code in an AWS CodeCommit repository)
+ Amazon Elastic Container Registry (Amazon ECR) (if you are using a build environment that relies on a Docker image in an Amazon ECR repository)
**Note**
As of July 26, 2022, the default IAM policy has been updated. For more information, see [Permissions required for AWS CodeBuild to connect to Amazon Elastic Container Registry](#ecr-policies).
+ Amazon Elastic Container Service (Amazon ECS) (if you are using a build environment that relies on a Docker image in an Amazon ECR repository)
+ AWS Identity and Access Management (IAM)
+ AWS Key Management Service (AWS KMS)
+ Amazon Simple Storage Service (Amazon S3)
If you create an IAM policy that is more restrictive than the minimum required permissions, the console won't function as intended.
## Permissions required for AWS CodeBuild to connect to Amazon Elastic Container Registry
As of July 26, 2022, AWS CodeBuild has updated its default IAM policy for Amazon ECR permission. The following permissions have been removed from the default policy:
```
"ecr:PutImage",
"ecr:InitiateLayerUpload",
"ecr:UploadLayerPart",
"ecr:CompleteLayerUpload"
```
For CodeBuild projects that were created before July 26, 2022, we recommend you update your policy with the following Amazon ECR policy:
```
"Action": [
"ecr:BatchCheckLayerAvailability",
"ecr:GetDownloadUrlForLayer",
"ecr:BatchGetImage"
]
```
For more information on updating your policy, see [Allow users to interact with CodeBuild](setting-up-service-permissions-group.md).
## Permissions required for the AWS CodeBuild console to connect to source providers
The AWS CodeBuild console uses the following API actions to connect to source providers (for example, GitHub repositories).
+ `codebuild:ListConnectedOAuthAccounts`
+ `codebuild:ListRepositories`
+ `codebuild:PersistOAuthToken`
+ `codebuild:ImportSourceCredentials`
You can associate source providers (such as GitHub repositories) with your build projects using the AWS CodeBuild console. To do this, you must first add the preceding API actions to IAM access policies associated with the user you use to access the AWS CodeBuild console.
The `ListConnectedOAuthAccounts`, `ListRepositories`, and `PersistOAuthToken` API actions are not intended to be called by your code. Therefore, these API actions are not included in the AWS CLI and AWS SDKs.
## AWS managed (predefined) policies for AWS CodeBuild
AWS addresses many common use cases by providing standalone IAM policies that are created and administered by AWS. These AWS managed policies grant necessary permissions for common use cases so you can avoid having to investigate what permissions are needed. The managed policies for CodeBuild also provide permissions to perform operations in other services, such as IAM, AWS CodeCommit,Amazon EC2, Amazon ECR, Amazon SNS, and Amazon CloudWatch Events, as required for the responsibilities for the users who have been granted the policy in question. For example, the `AWSCodeBuildAdminAccess` policy is an administrative-level user policy that allows users with this policy to create and manage CloudWatch Events rules for project builds and Amazon SNS topics for notifications about project-related events (topics whose names are prefixed with `arn:aws:codebuild:`), as well as administer projects and report groups in CodeBuild. For more information, see [AWS Managed Policies](https://docs.aws.amazon.com/IAM/latest/UserGuide/access_policies_managed-vs-inline.html#aws-managed-policies) in the *IAM User Guide*.
The following AWS managed policies, which you can attach to users in your account, are specific to AWS CodeBuild.
**AWSCodeBuildAdminAccess**
Provides full access to CodeBuild including permissions to administrate CodeBuild build projects.
**AWSCodeBuildDeveloperAccess**
Provides access to CodeBuild but does not allow build project administration.
**AWSCodeBuildReadOnlyAccess**
Provides read-only access to CodeBuild.
To access build output artifacts that CodeBuild creates, you must also attach the AWS managed policy named `AmazonS3ReadOnlyAccess`.
To create and manage CodeBuild service roles, you must also attach the AWS managed policy named `IAMFullAccess`.
You can also create your own custom IAM policies to allow permissions for CodeBuild actions and resources. You can attach these custom policies to the users or groups that require those permissions.
**Topics**
+ [AWSCodeBuildAdminAccess](#admin-access-policy)
+ [AWSCodeBuildDeveloperAccess](#developer-access-policy)
+ [AWSCodeBuildReadOnlyAccess](#read-only-access-policy)
### AWSCodeBuildAdminAccess
The `AWSCodeBuildAdminAccess` policy provides full access to CodeBuild, including permissions to administer CodeBuild build projects. Apply this policy only to administrative-level users to grant them full control over CodeBuild projects, report groups, and related resources in your AWS account, including the ability to delete projects and report groups.
For the full managed policy, see [ AWSCodeBuildAdminAccess ](https://docs.aws.amazon.com/aws-managed-policy/latest/reference/AWSCodeBuildAdminAccess.html) in the IAM managed policy reference.
### AWSCodeBuildDeveloperAccess
The `AWSCodeBuildDeveloperAccess` policy allows access to all of the functionality of CodeBuild and project and report group-related resources. This policy does not allow users to delete CodeBuild projects or report groups, or related resources in other AWS services, such as CloudWatch Events. We recommend that you apply this policy to most users.
For the full managed policy, see [ AWSCodeBuildDeveloperAccess ](https://docs.aws.amazon.com/aws-managed-policy/latest/reference/AWSCodeBuildDeveloperAccess.html) in the IAM managed policy reference.
### AWSCodeBuildReadOnlyAccess
The `AWSCodeBuildReadOnlyAccess` policy grants read-only access to CodeBuild and related resources in other AWS services. Apply this policy to users who can view and run builds, view projects, and view report groups, but cannot make any changes to them.
For the full managed policy, see [ AWSCodeBuildReadOnlyAccess ](https://docs.aws.amazon.com/aws-managed-policy/latest/reference/AWSCodeBuildReadOnlyAccess.xml) in the IAM managed policy reference.
## CodeBuild managed policies and notifications
CodeBuild supports notifications, which can notify users of important changes to build projects. Managed policies for CodeBuild include policy statements for notification functionality. For more information, see [What are notifications?](https://docs.aws.amazon.com/codestar-notifications/latest/userguide/welcome.html).
### Permissions related to notifications in read-only managed policies
The `AWSCodeBuildReadOnlyAccess` managed policy includes the following statements to allow read-only access to notifications. Users with this managed policy applied can view notifications for resources, but cannot create, manage, or subscribe to them.
```
{
"Sid": "CodeStarNotificationsPowerUserAccess",
"Effect": "Allow",
"Action": [
"codestar-notifications:DescribeNotificationRule"
],
"Resource": "*",

## Customer-managed policy examples
In this section, you can find example user policies that grant permissions for AWS CodeBuild actions. These policies work when you are using the CodeBuild API, AWS SDKs, or AWS CLI. When you are using the console, you must grant additional, console-specific permissions. For information, see [Permissions required to use the AWS CodeBuild console](#console-permissions).
You can use the following sample IAM policies to limit CodeBuild access for your users and roles.

# AWS CodeBuild permissions reference
You can use AWS-wide condition keys in your AWS CodeBuild policies to express conditions. For a list, see [Available Keys](https://docs.aws.amazon.com/IAM/latest/UserGuide/reference_policies_elements.html#AvailableKeys) in the *IAM User Guide*.
You specify the actions in the policy's `Action` field. To specify an action, use the `codebuild:` prefix followed by the API operation name (for example, `codebuild:CreateProject` and `codebuild:StartBuild`). To specify multiple actions in a single statement, separate them with commas (for example, `"Action": [ "codebuild:CreateProject", "codebuild:StartBuild" ]`).
**Using Wildcard Characters**
You specify an ARN, with or without a wildcard character (\$1), as the resource value in the policy's `Resource` field. You can use a wildcard to specify multiple actions or resources. For example, `codebuild:*` specifies all CodeBuild actions and `codebuild:Batch*` specifies all CodeBuild actions that begin with the word `Batch`. The following example grants access to all build project with names that begin with `my`:
```
arn:aws:codebuild:us-east-2:123456789012:project/my*

# Using tags to control access to AWS CodeBuild resources
Conditions in IAM policy statements are part of the syntax that you can use to specify permissions to CodeBuild project-based actions. You can create a policy that allows or denies actions on projects based on the tags associated with those projects, and then apply those policies to the IAM groups you configure for managing users. For information about applying tags to a project using the console or AWS CLI, see [Create a build project in AWS CodeBuild](create-project.md). For information about applying tags using the CodeBuild SDK, see [CreateProject ](https://docs.aws.amazon.com/codebuild/latest/APIReference/API_CreateProject.html#API_CreateProject_RequestSyntax) and [Tags](https://docs.aws.amazon.com/codebuild/latest/APIReference/API_Tag.html) in the *CodeBuild API Reference*. For information about using tags to control access to AWS resources, see [Controlling Access to AWS Resources Using Resource Tags](https://docs.aws.amazon.com/IAM/latest/UserGuide/access_tags.html) in the *IAM User Guide*.
**Important**
When using the reserved capacity feature, data cached on fleet instances, including source files, Docker layers, and cached directories specified in the buildspec, can be accessible to other projects within the same account. This is by design and allows projects within the same account to share fleet instances.
**Example 1: Limit CodeBuild project actions based on resource tags**
The following example denies all `BatchGetProjects` actions on projects tagged with the key `Environment` with the key value of `Production`. A user's administrator must attach this IAM policy in addition to the managed user policy to unauthorized users. The `aws:ResourceTag` condition key is used to control access to resources based on their tags.
****
```
{
"Version":"2012-10-17",
"Statement": [
{
"Effect": "Deny",
"Action": [
"codebuild:BatchGetProjects"
],
"Resource": "*",
"Condition": {
"ForAnyValue:StringEquals": {
"aws:ResourceTag/Environment": "Production"
}
}
}
]
}
```
**Example 2: Limit CodeBuild project actions based on request tags**
The following policy denies users permission to the `CreateProject` action if the request contains a tag with the key `Environment` and the key value `Production`. In addition, the policy prevents these unauthorized users from modifying projects by using the `aws:TagKeys` condition key to not allow `UpdateProject` if the request contains a tag with the key `Environment`. An administrator must attach this IAM policy in addition to the managed user policy to users who are not authorized to perform these actions. The `aws:RequestTag` condition key is used to control which tags can be passed in an IAM request
****
```
{
"Version":"2012-10-17",
"Statement": [
{
"Effect": "Deny",
"Action": [
"codebuild:CreateProject"
],
"Resource": "*",
"Condition": {
"ForAnyValue:StringEquals": {
"aws:RequestTag/Environment": "Production"
}
}
},
{
"Effect": "Deny",
"Action": [
"codebuild:UpdateProject"
],
"Resource": "*",
"Condition": {
"ForAnyValue:StringEquals": {
"aws:TagKeys": ["Environment"]
}
}
}
]
}
```
**Example 3: Deny or allow actions on report groups based on resource tags**
You can create a policy that allows or denies actions on CodeBuild resources (projects and report groups) based on the AWS tags associated with those resources, and then apply those policies to the IAM groups you configure for managing users. For example, you can create a policy that denies all CodeBuild actions on any report group with the AWS tag key `Status` and the key value of `Secret`, and then apply that policy to the IAM group you created for general developers (*Developers*). You then need to make sure that the developers working on those tagged report groups are not members of that general *Developers* group, but belong instead to a different IAM group that does not have the restrictive policy applied (`SecretDevelopers`).
The following example denies all CodeBuild actions on report groups tagged with the key `Status` and the key value of `Secret`:
****
```
{
"Version":"2012-10-17",
"Statement": [
{
"Effect": "Deny",
"Action": [
"codebuild:BatchGetReportGroups",
"codebuild:CreateReportGroup",
"codebuild:DeleteReportGroup",
"codebuild:ListReportGroups",
"codebuild:ListReportsForReportGroup",
"codebuild:UpdateReportGroup"
],
"Resource": "*",
"Condition": {
"StringLike": {
"aws:RequestedRegion": "us-east-1"
}
}
}
]
}
```
**Example 4: Limit CodeBuild actions to AWSCodeBuildDeveloperAccess based on resource tags**
You can create policies that allow CodeBuild actions on all report groups and projects that are not tagged with specific tags. For example, the following policy allows the equivalent of [AWSCodeBuildDeveloperAccess](auth-and-access-control-iam-identity-based-access-control.md#developer-access-policy) permissions for all report groups and projects except those tagged with the specified tags:
****

# Viewing resources in the console
The AWS CodeBuild console requires the `ListRepositories` permission to display a list of repositories for your AWS account in the AWS Region where you are signed in. The console also includes a **Go to resource** function to quickly perform a case insensitive search for resources. This search is performed in your AWS account in the AWS Region where you are signed in. The following resources are displayed across the following services:
+ AWS CodeBuild: Build projects
+ AWS CodeCommit: Repositories
+ AWS CodeDeploy: Applications
+ AWS CodePipeline: Pipelines
To perform this search across resources in all services, you must have the following permissions:
+ CodeBuild: `ListProjects`
+ CodeCommit: `ListRepositories`
+ CodeDeploy: `ListApplications`
+ CodePipeline: `ListPipelines`
Results are not returned for a service's resources if you do not have permissions for that service. Even if you have permissions for viewing resources, some resources are not returned if there is an explicit `Deny` to view those resources.
# Compliance validation for AWS CodeBuild
To learn whether an AWS service is within the scope of specific compliance programs, see [AWS services in Scope by Compliance Program](https://aws.amazon.com/compliance/services-in-scope/) and choose the compliance program that you are interested in. For general information, see [AWS Compliance Programs](https://aws.amazon.com/compliance/programs/).
You can download third-party audit reports using AWS Artifact. For more information, see [Downloading Reports in AWS Artifact](https://docs.aws.amazon.com/artifact/latest/ug/downloading-documents.html).
Your compliance responsibility when using AWS services is determined by the sensitivity of your data, your company's compliance objectives, and applicable laws and regulations. For more information about your compliance responsibility when using AWS services, see [AWS Security Documentation](https://docs.aws.amazon.com/security/).
# Resilience in AWS CodeBuild
The AWS global infrastructure is built around AWS Regions and Availability Zones. AWS Regions provide multiple physically separated and isolated Availability Zones, which are connected with low-latency, high-throughput, and highly redundant networking. With Availability Zones, you can design and operate applications and databases that automatically fail over between Availability Zones without interruption. Availability Zones are more highly available, fault tolerant, and scalable than traditional single or multiple data center infrastructures.
For more information about AWS Regions and Availability Zones, see [AWS global infrastructure](https://aws.amazon.com/about-aws/global-infrastructure/).
# Infrastructure Security in AWS CodeBuild
As a managed service, AWS CodeBuild is protected by AWS global network security. For information about AWS security services and how AWS protects infrastructure, see [AWS Cloud Security](https://aws.amazon.com/security/). To design your AWS environment using the best practices for infrastructure security, see [Infrastructure Protection](https://docs.aws.amazon.com/wellarchitected/latest/security-pillar/infrastructure-protection.html) in *Security Pillar AWS Well‐Architected Framework*.
You use AWS published API calls to access CodeBuild through the network. Clients must support the following:
+ Transport Layer Security (TLS). We require TLS 1.2 and recommend TLS 1.3.
+ Cipher suites with perfect forward secrecy (PFS) such as DHE (Ephemeral Diffie-Hellman) or ECDHE (Elliptic Curve Ephemeral Diffie-Hellman). Most modern systems such as Java 7 and later support these modes.
# Access your source provider in CodeBuild
For GitHub or GitHub Enterprise Server, you use a personal access token, a Secrets Manager secret, a connection, or an OAuth app to access the source provider. For Bitbucket, you use either an access token, an app password, a Secrets Manager secret, a connection, or an OAuth app to access the source provider.
**Topics**
+ [Create and store a token in a Secrets Manager secret](asm-create-secret.md)
+ [GitHub and GitHub Enterprise Server access in CodeBuild](access-tokens-github-overview.md)
+ [Bitbucket access in CodeBuild](access-tokens-bitbucket-overview.md)
+ [GitLab access in CodeBuild](access-tokens-gitlab-overview.md)
# Create and store a token in a Secrets Manager secret
If you choose to use to store your access token using Secrets Manager, you can use either an existing secret connection or create a new secret. To create a new secret, do the following:
------
#### [ AWS Management Console ]
**To create a Secrets Manager secret in the AWS Management Console**
1. For **Source provider**, choose **Bitbucket**, **GitHub**, or **GitHub Enterprise**.
1. For **Credential**, do one of the following:
+ Choose **Default source credential** to use your account's default source credential to apply to all projects.
1. If you aren't connected to your source provider, choose **Manage default source credential**.
1. For **Credential type**, choose a credential type other than **CodeConnections**.
1. For **Service**, choose **Secrets Manager** and for **Secrets** choose **New secret**.
1. In **Secret name**, enter the name of your secret.
1. In **Secret description - optional**, enter a description for your secret.
1. Depending on the source provider you chose, enter your token or username and app password and choose **Save**.
+ Choose **Custom source credential** to use a custom source credential to override your account's default settings.
1. For **Credential type**, choose a credential type other than **CodeConnections**.
1. In **Connection**, choose **Create a secret**.
1. In **Secret name**, enter the name of your secret.
1. In **Secret description - optional**, enter a description for your secret.
1. Depending on the source provider you chose, enter your token or username and app password, and choose **Create**.
------
#### [ AWS CLI ]
**To create a Secrets Manager secret in the AWS CLI**
+ Open a terminal (Linux, macOS, or Unix) or command prompt (Windows). Use the AWS CLI to run the Secrets Manager **create-secret** command.
```
aws secretsmanager create-secret --region \
--name '' \
--description '' \
--secret-string '{
"ServerType":"",
"AuthType":"",
"Token":""
}' \
--tags Key=codebuild:source,Value='' \
Key=codebuild:source:type,Value= \
Key=codebuild:source:provider,Value=
```
The Secrets Manager secrets that CodeBuild accept must be in the same account and AWS Region as the CodeBuild project and must be in the following JSON format:
```
{
"ServerType": ServerType,
"AuthType: AuthType,
"Token": string,
"Username": string // Optional and is only used for Bitbucket app password
}
```
[\[See the AWS documentation website for more details\]](http://docs.aws.amazon.com/codebuild/latest/userguide/asm-create-secret.html)
Additionally, CodeBuild uses the following resource tags on the secret to ensure the secrets are easily selectable when creating or editing projects.
[\[See the AWS documentation website for more details\]](http://docs.aws.amazon.com/codebuild/latest/userguide/asm-create-secret.html)

# GitHub and GitHub Enterprise Server access in CodeBuild
For GitHub, you can use a personal access token, an OAuth app, a Secrets Manager secret, or a GitHub App connection to access the source provider. For GitHub Enterprise Server, you can use a personal access token, a Secrets Manager secret, or a GitHub App connection to access the source provider.
**Topics**
+ [GitHub App connections for GitHub and GitHub Enterprise Server](connections-github-app.md)
+ [GitHub and GitHub Enterprise Server access token](access-tokens-github.md)
+ [GitHub OAuth app](oauth-app-github.md)
# GitHub App connections for GitHub and GitHub Enterprise Server
You can use GitHub App to connect with CodeBuild. GitHub App connections are supported through [AWS CodeConnections](https://docs.aws.amazon.com/dtconsole/latest/userguide/welcome-connections.html).
The source provider access enables you to trigger a build by subscribing to [GitHub webhook events](github-webhook.md) using [ CreateWebhook](https://docs.aws.amazon.com/codebuild/latest/APIReference/API_CreateWebhook.html), or to use [Tutorial: Configure a CodeBuild-hosted GitHub Actions runner](action-runner.md) in CodeBuild.
**Note**
CodeConnections is available in fewer regions than CodeBuild. You can use cross-region connections in CodeBuild. Connections created in opt-in regions, cannot be used in other regions. For more information, see [AWS CodeConnections endpoints and quotas](https://docs.aws.amazon.com/general/latest/gr/codestar_connections.html).

+ [Step 3: Configure CodeBuild to use the new connection](#connections-github-account-credential)
+ [Troubleshooting the GitHub App](#connections-github-troubleshooting)
## Step 1: Create a connection to GitHub App (console)
Use these steps to use the CodeBuild console to add a connection for your project in GitHub.
**To create a connection to GitHub**
+ Follow the instructions in the *Developer Tools User Guide* for [Create a connection to GitHub](https://docs.aws.amazon.com/dtconsole/latest/userguide/connections-create-github.html).
**Note**
Instead of creating or using an existing connection in your account, you can use a connection shared from another AWS account. For more information, see [Share connections with AWS accounts](https://docs.aws.amazon.com/dtconsole/latest/userguide/connections-share.html).
## Step 2: Grant CodeBuild project IAM role access to use the connection
You can grant CodeBuild project IAM role access to use the GitHub tokens vended by your connection.
**To grant CodeBuild project IAM role access**
1. Create an IAM role for your CodeBuild project by following the instructions to [Allow CodeBuild to interact with other AWS services](setting-up-service-role.md) for your CodeBuild project.
1. While following the instructions, add the following IAM policy to your CodeBuild project role to grant access to the connection.
------
#### [ JSON ]
****
```
{
"Version":"2012-10-17",
"Statement": [
{
"Effect": "Allow",
"Action": [
"codeconnections:GetConnectionToken",
"codeconnections:GetConnection"
],
"Resource": [
"arn:aws:iam::*:role/Service*"
]
}
]
}
```
------
## Step 3: Configure CodeBuild to use the new connection
You can configure a connection as an account level credential and use it in a project.
------
#### [ AWS Management Console ]
**To configure a connection as an account level credential in the AWS Management Console**
1. For **Source provider**, choose **GitHub**.
1. For **Credential**, do one of the following:
+ Choose **Default source credential** to use your account's default source credential to apply to all projects.
1. If you aren't connected to GitHub, choose **Manage default source credential**.
1. For **Credential type**, choose **GitHub App**.
1. In **Connection**, choose to use an existing connection or create a new connection.
+ Choose **Custom source credential** to use a custom source credential to override your account's default settings.
1. For **Credential type**, choose **GitHub App**.
1. In **Connection**, choose to use an existing connection or create a new connection.
------
#### [ AWS CLI ]
**To configure a connection as an account level credential in the AWS CLI**
+ Open a terminal (Linux, macOS, or Unix) or command prompt (Windows). Use the AWS CLI to run the **import-source-credentials** command, specifying the `--auth-type`, `--server-type`, and `--token` for your connection.
Use the following command:
```
aws codebuild import-source-credentials --auth-type CODECONNECTIONS --server-type GITHUB --token
```
------
You can also set up multiple tokens for your CodeBuild projects. For more information, see [Configure multiple tokens as source level credentials](multiple-access-tokens.md#asm-source-credential).
## Troubleshooting problems with the GitHub App
The following information can help you troubleshoot common issues with the GitHub App.
**Topics**
+ [Install the AWS Connector for GitHub app in an undesired region](#connections-github-troubleshooting.undesired-region)
+ [The GitHub App connection doesn't have access to repositories](#connections-github-troubleshooting.repo-access)
+ [The AWS service's IAM role is missing necessary IAM permissions.](#connections-github-troubleshooting.iam-permissions)
### Install the AWS Connector for GitHub app in an undesired region
**Issue:** You installed the AWS Connector for GitHub from the GitHub Marketplace, but the connection was created in an undesired region. If you attempt to reconfigure the app on the GitHub website, it won't work because the app is already installed on your GitHub account.
**Possible cause:** The app is already installed in your GitHub account, so you can only reconfigure the app permissions.
**Recommended solution:** You can create a new connection with the installation ID in the desired region.
1. Open the CodeConnections console at [https://console.aws.amazon.com/codesuite/settings/connections](https://console.aws.amazon.com/codesuite/settings/connections) and navigate to the desired region using the region selector in the AWS console navigation bar.
1. Follow the instructions in the *Developer Tools User Guide* for [Create a connection to GitHub](https://docs.aws.amazon.com/dtconsole/latest/userguide/connections-create-github.html).
**Note**
Since you've already installed the AWS Connector for GitHub app, you can choose it instead of installing a new app.
### The GitHub App connection doesn't have access to repositories
**Issue:** An AWS service using the connection, such as CodeBuild or CodePipeline, reports that it doesn't have access to the repository or the repository doesn't exist. Some possible error messages include:
+ `Authentication required for primary source.`
+ `Unable to create webhook at this time. Please try again later.`
+ `Failed to create webhook. GitHub API limit reached. Please try again later.`
***Possible cause:** You might have been using the GitHub app and haven't granted the webhook permission scope.*
**Recommended solution:** To grant the required permission scope, follow the instructions in [ Navigating to the GitHub App you want to review or modify](https://docs.github.com/en/apps/using-github-apps/reviewing-and-modifying-installed-github-apps#navigating-to-the-github-app-you-want-to-review-or-modify) to configure the installed app. Under the permissions section, you'll see the app doesn't have webhooks permission, and there is an option for you to review the newly requested permissions. Review and accept the new permissions. For more infomation, see [ Approving updated permissions for a GitHub App](https://docs.github.com/en/apps/using-github-apps/approving-updated-permissions-for-a-github-app).
***Possible cause:** The connection was working as expected, but suddenly doesn’t have access to the repositories.*
**Possible solution:** Start by reviewing your [ authorizations](https://docs.github.com/en/apps/using-github-apps/reviewing-and-revoking-authorization-of-github-apps) and your [ installations](https://docs.github.com/en/apps/using-github-apps/reviewing-and-modifying-installed-github-apps), then verify the GitHub App is authorized and installed. If the GitHub App installation is suspended, then you need to unsuspended it. If the GitHub App is not authorized for a [UAT (User Access Token)](https://docs.github.com/en/apps/creating-github-apps/authenticating-with-a-github-app/authenticating-with-a-github-app-on-behalf-of-a-user) connection, or not installed for an [ IAT (Installation Access Token)](https://docs.github.com/en/apps/creating-github-apps/authenticating-with-a-github-app/authenticating-as-a-github-app-installation) connection, the existing connection is not usable any more, and you will need to create a new connection. Note that reinstalling the GitHub App will not revive the previous connection that was associated to the old installation.
**Possible solution:** If the connection is a UAT connection, make sure the connection is not concurrently being used, such as a being used in multiple CodeBuild concurrent runs of build. This is because GitHub immediately invalidates a previously issued UAT if an expiring token is refreshed by the connection. If you need to use UAT connection for multiple concurrent CodeBuild builds, you can create multiple connections and use each connection independently.
**Possible solution:** If the UAT connection hasn't been used in the past 6 months, the connection will be invalidated by GitHub. To fix this, create a new connection.
***Possible cause:** You might have been using a UAT connection without installing the app.*
**Recommended solution:** Though creating a UAT connection doesn't require associating the connection with a GitHub App installation, an installation is required for the repository to be accessible. Follow the instructions to [ review installations](https://docs.github.com/en/apps/using-github-apps/reviewing-and-modifying-installed-github-apps) to make sure the GitHub App is installed. If it is not installed, navigate to the [GitHub App's page](https://github.com/marketplace/aws-connector-for-github) to install the app. For more information about UAT's access, see [About user access tokens](https://docs.github.com/en/apps/creating-github-apps/authenticating-with-a-github-app/generating-a-user-access-token-for-a-github-app#about-user-access-tokens).
### The AWS service's IAM role is missing necessary IAM permissions.
**Issue:** You see any of the following error messages:
+ `Access denied to connection `
+ `Failed to get access token from `
**Recommended solution:** Typically you use a connection with an AWS service, such as CodePipeline or CodeBuild. When you give the AWS service an IAM role, the AWS service can use the role's permission to act on your behalf. Make sure the IAM role has necessary permission. For more information about the necessary IAM permission, see [Grant CodeBuild project IAM role access to use the connection](#connections-github-role-access) and [Identity and access management for AWS CodeStar Notifications and CodeConnections](https://docs.aws.amazon.com/dtconsole/latest/userguide/security-iam.html) in the *Developer Tools console User Guide*.
# GitHub and GitHub Enterprise Server access token
## Access token prerequisites
Before you begin, you must add the proper permission scopes to your GitHub access token.
For GitHub, your personal access token must have the following scopes.
+ **repo**: Grants full control of private repositories.
+ **repo:status**: Grants read/write access to public and private repository commit statuses.
+ **admin:repo\$1hook**: Grants full control of repository hooks. This scope is not required if your token has the `repo` scope.
+ **admin:org\$1hook**: Grants full control of organization hooks. This scope is only required if you are using the organization webhook feature.
For more information, see [Understanding scopes for OAuth apps](https://developer.github.com/apps/building-oauth-apps/understanding-scopes-for-oauth-apps/) on the GitHub website.
If you are using fine-grained personal access tokens, depending on your use case, your personal access token might need the following permissions:
+ **Contents: Read-only**: Grants access to private repositories. This permission is required if you are using private repositories as source.
+ **Commit statuses: Read and write**: Grants permission to create commit statuses. This permission is required if your project has webhook set up, or you have report build status feature enabled.
+ **Webhooks: Read and write**: Grants permission to manage webhooks. This permission is required if your project has webhook set up.
+ **Pull requests: Read-only**: Grants permission to access pull requests. This permission is required if your webhook has a `FILE_PATH` filter on pull request events.
+ **Administration: Read and write**: This permission is required if you are using the self-hosted GitHub Actions runner feature with CodeBuild. For more details, see [Create a registration token for a repository](https://docs.github.com/en/rest/actions/self-hosted-runners?apiVersion=2022-11-28#create-a-registration-token-for-a-repository) and [Tutorial: Configure a CodeBuild-hosted GitHub Actions runner](action-runner.md).
**Note**
If you want to access organization repositories, make sure you specify the organization as the resource owner of the access token.

## Connect GitHub with an access token (console)
To use the console to connect your project to GitHub using an access token, do the following when you create a project. For information, see [Create a build project (console)](create-project.md#create-project-console).
1. For **Source provider**, choose **GitHub**.
1. For **Credential**, do one of the following:
+ Choose to use account credentials to apply your account's default source credential to all projects.
1. If you aren't connected to GitHub, choose **Manage account credential**.
1. For **Credential type**, choose **Personal access token**.
+ If you chose to use account level credentials for **Service**, choose which service you'd like to use to store your token and do the following:
1. If you choose to use **Secrets Manager**, you can choose to use an existing secret connection or create a new secret, and then choose **Save**. For more information how to create a new secret, see [Create and store a token in a Secrets Manager secret](asm-create-secret.md).
1. If you choose to use **CodeBuild**, enter your GitHub personal access token, and then choose **Save**.
+ Select **Use override credentials for this project only** to use a custom source credential to override your account's credential settings.
1. From the populated credential list, choose one of the options under **Personal access token**.
1. You can also create new personal access token by selecting **create a new personal access token connection** in the description.
## Connect GitHub with an access token (CLI)
Follow these steps to use the AWS CLI to connect your project to GitHub using an access token. For information about using the AWS CLI with AWS CodeBuild, see the [Command line reference](cmd-ref.md).
1. Run the **import-source-credentials** command:
```
aws codebuild import-source-credentials --generate-cli-skeleton
```
JSON-formatted data appears in the output. Copy the data to a file (for example, `import-source-credentials.json`) in a location on the local computer or instance where the AWS CLI is installed. Modify the copied data as follows, and save your results.
```
{
"serverType": "server-type",
"authType": "auth-type",
"shouldOverwrite": "should-overwrite",
"token": "token",
"username": "username"
}
```
Replace the following:
+ *server-type*: Required value. The source provider used for this credential. Valid values are GITHUB, BITBUCKET, GITHUB\$1ENTERPRISE, GITLAB, and GITLAB\$1SELF\$1MANAGED.
+ *auth-type*: Required value. The type of authentication used to connect to a repository. Valid values are OAUTH, BASIC\$1AUTH, PERSONAL\$1ACCESS\$1TOKEN, CODECONNECTIONS, and SECRETS\$1MANAGER. For GitHub, only PERSONAL\$1ACCESS\$1TOKEN is allowed. BASIC\$1AUTH is only allowed with Bitbucket app password.
+ *should-overwrite*: Optional value. Set to `false` to prevent overwriting the repository source credentials. Set to `true` to overwrite the repository source credentials. The default value is `true`.
+ *token*: Required value. For GitHub or GitHub Enterprise Server, this is the personal access token. For Bitbucket, this is the personal access token or app password. For the auth-type CODECONNECTIONS, this is the connection ARN. For the auth-type SECRETS\$1MANAGER, this is the secret ARN.
+ *username*: Optional value. This parameter is ignored for GitHub and GitHub Enterprise Server source providers.
1. To connect your account with an access token, switch to the directory that contains the `import-source-credentials.json` file you saved in step 1 and run the **import-source-credentials** command again.
```
aws codebuild import-source-credentials --cli-input-json file://import-source-credentials.json
```
JSON-formatted data appears in the output with an Amazon Resource Name (ARN).
```
{
"arn": "arn:aws:codebuild:region:account-id:token/server-type"
}
```
**Note**
If you run the **import-source-credentials** command with the same server type and auth type a second time, the stored access token is updated.
After your account is connected with an access token, you can use `create-project` to create your CodeBuild project. For more information, see [Create a build project (AWS CLI)](create-project.md#create-project-cli).
1. To view the connected access tokens, run the **list-source-credentials** command.
```
aws codebuild list-source-credentials
```
A JSON-formatted `sourceCredentialsInfos` object appears in the output:
```
{
"sourceCredentialsInfos": [
{
"authType": "auth-type",
"serverType": "server-type",
"arn": "arn"
}
]
}
```
The `sourceCredentialsObject` contains a list of connected source credentials information:
+ The `authType` is the type of authentication used by credentials. This can be `OAUTH`, `BASIC_AUTH`, `PERSONAL_ACCESS_TOKEN`, `CODECONNECTIONS`, or `SECRETS_MANAGER`.
+ The `serverType` is the type of source provider. This can be `GITHUB`, `GITHUB_ENTERPRISE`, `BITBUCKET`, `GITLAB`, or `GITLAB_SELF_MANAGED`.
+ The `arn` is the ARN of the token.
1. To disconnect from a source provider and remove its access tokens, run the **delete-source-credentials** command with its ARN.
```
aws codebuild delete-source-credentials --arn arn-of-your-credentials
```
JSON-formatted data is returned with an ARN of the deleted credentials.
```
{
"arn": "arn:aws:codebuild:region:account-id:token/server-type"
}
```

# GitLab access in CodeBuild
For GitLab, you use a GitLab connection to access the source provider.
**Topics**
+ [Connect CodeBuild to GitLab](#connections-gitlab)
## Connect CodeBuild to GitLab
Connections allow you to authorize and establish configurations that associate your third-party provider with your AWS resources using AWS CodeConnections. To associate your third-party repository as a source for your build project, you use a connection.
To add a GitLab or GitLab Self Managed source provider in CodeBuild, you can choose either to:
+ Use the CodeBuild console **Create build project** wizard or **Edit Source** page to choose the **GitLab** or **GitLab Self Managed** provider option. See [Create a connection to GitLab (console)](#connections-gitlab-console) to add the source provider. The console helps you create a connections resource.
+ Use the CLI to create your connections resources, see [Create a connection to GitLab (CLI)](#connections-gitlab-cli) to create a connections resource with the CLI.
**Note**
You can also create a connection using the Developer Tools console under **Settings**. See [Create a Connection](https://docs.aws.amazon.com/dtconsole/latest/userguide/connections-create.html).
**Note**
By authorizing this connection installation in GitLab, you grant our service permissions to process your data by accessing your account, and you can revoke the permissions at any time by uninstalling the application.
### Create a connection to GitLab
This section describes how to connect GitLab to CodeBuild. For more information about GitLab connections, see [Connect CodeBuild to GitLab](#connections-gitlab).
Before you begin:
+ You must have already created an account with GitLab.
**Note**
Connections only provide access to repositories owned by the account that was used to create and authorize the connection.
**Note**
You can create connections to a repository where you have the **Owner** role in GitLab, and then the connection can be used with the repository with resources such as CodeBuild. For repositories in groups, you do not need to be the group owner.
+ To specify a source for your build project, you must have already created a repository on GitLab.
**Topics**
+ [Create a connection to GitLab (console)](#connections-gitlab-console)
+ [Create a connection to GitLab (CLI)](#connections-gitlab-cli)
#### Create a connection to GitLab (console)
Use these steps to use the CodeBuild console to add a connection for your project (repository) in GitLab.
**Note**
Instead of creating or using an existing connection in your account, you can use a connection shared from another AWS account. For more information, see [Share connections with AWS accounts](https://docs.aws.amazon.com/dtconsole/latest/userguide/connections-share.html).
**To create or edit your build project**
1. Sign in to the CodeBuild console.
1. Choose one of the following.
+ Choose to create a build project. Follow the steps in [Create a build project (console)](create-project.md#create-project-console) to complete the first screen and in the **Source** section, under **Source Provider**, choose **GitLab**.
+ Choose to edit an existing build project. Choose **Edit**, and then choose **Source**. In the **Edit Source** page, under **Source provider**, choose **GitLab**.
1. Choose one of the following:
+ Under **Connection**, choose ** Default connection**. Default connection applies a default GitLab connection across all projects.
+ Under **Connection**, choose ** Custom connection**. Custom connection applies a custom GitLab connection that overrides your account's default settings.
1. Do one of the following:
+ Under **Default connection** or **Custom connection**, if you have not already created a connection to your provider, choose **Create a new GitLab connection**. Proceed to step 5 to create the connection.
+ Under **Connection**, if you have already created a connection to your provider, choose the connection. Proceed to step 10.
**Note**
If you close the pop-up window before a GitLab connection is created, you need to refresh the page.
1. To create a connection to a GitLab repository, under **Select a provider**, choose **GitLab**. In **Connection name**, enter the name for the connection that you want to create. Choose **Connect to GitLab**.
![\[Console screenshot showing connection option selected for GitLab.\]](http://docs.aws.amazon.com/codebuild/latest/userguide/images/connections-create-gitlab.png)
1. When the sign-in page for GitLab displays, log in with your credentials, and then choose **Sign in**.
1. If this is your first time authorizing the connection, an authorization page displays with a message requesting authorization for the connection to access your GitLab account.
Choose **Authorize**.
![\[Screenshot showing the message to authorize the connection for your GitLab account.\]](http://docs.aws.amazon.com/codebuild/latest/userguide/images/gitlab-authorization.png)
1. The browser returns to the connections console page. Under **GitLab connection settings**, the new connection is shown in **Connection name**.
1. Choose **Connect**.
After a GitLab connection is successfully created, a success banner will be displayed at the top.
1. On the **Create build project** page, in the **Default connection** or **Custom connection** drop-down list, make sure your connection ARN is listed. If not, choose the refresh button to have it appear.
1. In **Repository**, choose the name of your project in GitLab by specifying the project path with the namespace. For example, for a group-level repository, enter the repository name in the following format: `group-name/repository-name`. For more information about the path and namespace, see the `path_with_namespace` field in [https://docs.gitlab.com/ee/api/projects.html\$1get-single-project](https://docs.gitlab.com/ee/api/projects.html#get-single-project). For more information about the namespace in GitLab, see [https://docs.gitlab.com/ee/user/namespace/](https://docs.gitlab.com/ee/user/namespace/).
**Note**
For groups in GitLab, you must manually specify the project path with the namespace. For example, for a repository named `myrepo` in a group `mygroup`, enter the following: `mygroup/myrepo`. You can find the project path with the namespace in the URL in GitLab.
1. In **Source version - optional**, enter a pull request ID, branch, commit ID, tag, or reference and a commit ID. For more information, see [Source version sample with AWS CodeBuild](sample-source-version.md).
**Note**
We recommend that you choose Git branch names that don't look like commit IDs, such as `811dd1ba1aba14473856cee38308caed7190c0d` or `5392f7`. This helps you avoid Git checkout collisions with actual commits.
1. In **Git clone depth - optional**, you can create a shallow clone with a history truncated to the specified number of commits. If you want a full clone, choose **Full**.
1. In **Build Status - optional**, select **Report build statuses to source provider when your builds start and finish ** if you want the status of your build's start and completion reported to your source provider.
To be able to report the build status to the source provider, the user associated with the source provider must have write access to the repo. If the user does not have write access, the build status cannot be updated. For more information, see [Source provider access](access-tokens.md).
#### Create a connection to GitLab (CLI)
You can use the AWS Command Line Interface (AWS CLI) to create a connection.
To do this, use the **create-connection** command.
**Important**
A connection created through the AWS CLI or AWS CloudFormation is in `PENDING` status by default. After you create a connection with the CLI or CloudFormation, use the console to edit the connection to make its status `AVAILABLE`.
**To create a connection**
+ Follow the instructions in the *Developer Tools console User Guide* for [Create a connection to GitLab (CLI)](https://docs.aws.amazon.com/dtconsole/latest/userguide/connections-create-gitlab.html#connections-create-gitlab-cli).
# Cross-service confused deputy prevention
The confused deputy problem is a security issue where an entity that doesn't have permission to perform an action can coerce a more-privileged entity to perform the action. In AWS, cross-service impersonation can result in the confused deputy problem. Cross-service impersonation can occur when one service (the *calling service*) calls another service (the *called service*). The calling service can be manipulated to use its permissions to act on another customer's resources in a way it should not otherwise have permission to access. To prevent this, AWS provides tools that help you protect your data for all services with service principals that have been given access to resources in your account.
We recommend using the [https://docs.aws.amazon.com/IAM/latest/UserGuide/reference_policies_condition-keys.html#condition-keys-sourcearn](https://docs.aws.amazon.com/IAM/latest/UserGuide/reference_policies_condition-keys.html#condition-keys-sourcearn) and [https://docs.aws.amazon.com/IAM/latest/UserGuide/reference_policies_condition-keys.html#condition-keys-sourceaccount](https://docs.aws.amazon.com/IAM/latest/UserGuide/reference_policies_condition-keys.html#condition-keys-sourceaccount) global condition context keys in resource policies to limit the permissions that AWS CodeBuild gives another service to the resource. Use `aws:SourceArn` if you want only one resource to be associated with the cross-service access. Use `aws:SourceAccount` if you want to allow any resource in that account to be associated with the cross-service use.
The most effective way to protect against the confused deputy problem is to use the `aws:SourceArn` global condition context key with the full ARN of the resource. If you don't know the full ARN of the resource or if you are specifying multiple resources, use the `aws:SourceArn` global context condition key with wildcard characters (`*`) for the unknown portions of the ARN. For example, `arn:aws:codebuild:*:123456789012:*`.
If the `aws:SourceArn` value does not contain the account ID, such as an Amazon S3 bucket ARN, you must use both global condition context keys to limit permissions.
The value of `aws:SourceArn` must be the CodeBuild project ARN.
The following example shows how you can use the `aws:SourceArn` and `aws:SourceAccount` global condition context keys in CodeBuild to prevent the confused deputy problem.
