GitHub

When you want to add new integrations to your Snyk account you need to first decide the level type at which you want to install the integration.

• Group level - Add integrations to your Snyk application that will be available for your Snyk AppRisk Essentials or Snyk AppRisk Pro. To set up integrations for Snyk AppRisk, use the Integrations menu at the Group level.

• Organization level - Add integrations for your Snyk application that will be available for all Snyk products, except Snyk AppRisk.

Organization level - Snyk integrations

Prerequisites for GitHub integration

• Internet-accessible repositories. If your repositories are not internet-accessible, you must use Snyk Broker.

• A public or private GitHub project.

• The required PAT and GitHub repository access scope permissions. For more information, see GitHub and GitHub Enterprise permissions requirements.

Known limitations of the GitHub integration

You cannot use the GitHub integration with a Snyk Service Account, as the GitHub integration is associated with your user account, not with the Snyk Organization.

Use the GitHub Enterprise integration to import public and private Projects using the API with a Snyk Service Account.

GitHub integration features

The GitHub integration allows you to:

• Continuously perform security scanning across all the integrated repositories

• Detect vulnerabilities in your open-source components

• Provide automated fixes and upgrades

Per user, not per Organization

The GitHub integration is set up for your user account, not for a Snyk Organization. GitHub integration settings apply to all Organizations associated with your user account but do not automatically apply to other user accounts in an Organization.

When you import a Snyk Project using your GitHub integration with the Snyk PR functionality enabled, Snyk PRs are created for that Project. However, if another user imports Projects with their GitHub integration after disabling the Snyk PR functionality, Snyk PRs are not created for the Projects they import.

How to set up the GitHub integration

To connect your GitHub repositories to Snyk for scanning, you need to set up the integration and then import Projects. For details, see Getting started.

GitHub integration settings

To see all settings for your GitHub integration, go to the GitHub Integration settings page, then navigate to Organization Settings, and select GitHub in the Integrations section:

You can then scroll down to the section required, and set the options accordingly:

• General settings

• Pull requests:

  • Opening fix and upgrade pull requests from a fixed GitHub account

  • Automatic fix PRs

  • Automatic dependency upgrade PRs

  • Pull request assignees

  • Snyk vulnerability patches

• Pull request status checks (PR Checks)

  • Open Source security and licenses

  • Code analysis

• Dockerfiles

  • Scan you Dockerfile

  • Fix vulnerable base images in your Dockerfile

General GitHub integration settings

Select General to view general settings:

GitHub integration general settings

• Integration ID: The unique ID for this integration, needed if you use the Snyk API.

• Repository access: Whether Snyk can access private repos (in addition to public repos). Changing this setting affects existing Projects.

GitHub integration features

After you have connected GitHub to Snyk, you can use:

• Project-level security reports

• Project monitoring and automatic fix pull requests

• Commit signing

• Pull request testing

Project-level security reports

Feature availability

Reports are available only for Enterprise plans. For more information, see plans and pricing.

Snyk produces advanced security reports that let you explore the vulnerabilities found in your repositories and fix them right away by opening a fix pull request directly in your repository, with the required upgrades or patches.

This example shows a Project-level security report.

Project-level security report

Project monitoring and automatic fix pull requests

Snyk scans your Projects on either a daily or a weekly basis. When new vulnerabilities are found, Snyk notifies you via email and opens automated pull requests with fixes for your repositories.

The example that follows shows a fix pull request opened by Snyk.

Fix pull request opened by Snyk

To review and adjust the automatic fix pull request settings in the Snyk GitHub Integration settings page, navigate to Organization Settings > Integrations > Source control > GitHub.

Scroll down to the Automatic fix PRs section and set the options. For definitions, see Configure automatic fix PRs at the integration level.

Automatic fix pull request settings

Commit signing

Feature availability

For availability with Snyk Broker, see the Commit signing page in the Broker docs.

All the commits in Snyk's pull requests are done by [e-mail] (a verified user on GitHub), and signed with a PGP key. All Snyk pull requests appear as verified on GitHub, thus providing your developers with the confidence that the fix and upgrade pull requests are generated by a trusted source.

Pull request status checks

The Snyk PR Checks feature allows Snyk to test any new PR in your repositories for security vulnerabilities and sends a status check to GitHub. This lets you see, directly in GitHub, whether or not the pull request introduces new security issues.

This example shows how Snyk PR checks appear on the GitHub pull request page.

Snyk pull request checks on GitHub pull request page

You can review and adjust the pull request test settings using the Snyk GitHub Integration settings page in Organization Settings > Integrations > Source control > GitHub.

GitHub user permissions and actions

In non-brokered GitHub integrations, operations that are triggered through the Snyk Web UI, for example, opening a Fix PR or re-testing a Project, are performed on behalf of the acting user.

Therefore, a user who wants to perform this operation on GitHub through the Snyk UI must connect their GitHub account to Snyk with the required permission scope for the repositories where they want to perform these operations. See GitHub and GitHub Enterprise permissions requirements for details.

Operations that are not triggered through the Snyk Web UI, such as daily and weekly tests and automatic PRs (fix and upgrade), are performed on behalf of random Snyk Organization members who have connected their GitHub accounts to Snyk and have the required permission scope for the repository.

For public repositories that are non-brokered, some operations, such as creating the PR, may occasionally be performed by [e-mail].

A Snyk Organization administrator can designate a specific GitHub account to use for opening fix and upgrade PRs.

Note that Snyk will continue to use a random Snyk Organization member's GitHub account to perform all the other operations. Therefore using this feature does not eliminate the need to connect users' GitHub accounts to Snyk.

How to set up a GitHub account to open Snyk PRs

Snyk lets you designate a specific GitHub account to open fix and upgrade pull requests.

The configured account is only used for opening PRs. All other operations are still performed on behalf of a randomly selected Snyk Organization member who has connected their GitHub accounts to Snyk.

To use this feature, follow these steps:

1. Go to the GitHub Integrations settings page in the Snyk Web UI using Organization Settings > Integrations > Source control > GitHub.

2. In the Open Snyk automatic PRs from a fixed GitHub account section, enter your GitHub personal access token. You can generate this from your GitHub account.

3. Click Save to enable this feature.

Set an account to open Snyk PRs

Ensure that the GitHub account that you designate to open Snyk PRs has write-level permissions or higher for the repos you want to monitor with Snyk.

See GitHub and GitHub Enterprise permissions requirements for more information.

How to assign pull requests to users

Feature availability

The Auto-assign PRs feature is supported only for private repositories.

Snyk can automatically assign the pull requests it creates to ensure that they are handled by the right team members.

Auto-assign for PRs can be enabled for the GitHub and GitHub Enterprise integration and all Projects imported via GitHub, or on a per-Project basis.

Users can either be manually specified, and all will be assigned, or automatically selected based on the last commit user account.

Enable Auto-assign for all Projects in the GitHub integration

To configure the Auto-assign settings for all the Projects from an imported private repository, go to the Github integration settings using Organization Settings > Integrations > Source control > GitHub and select Enable pull request assignees.

You can then choose to assign PRs to the last user to change the manifest file or specified contributors.

Auto-assign PRs in private repos

For pull request assignees, the option The last user to change the manifest file is based on blame data, not Git commits.

Enable Auto-assign for a single Project

To configure the Auto-assign settings for a specific Project from an imported private repository, follow these steps:

1. In the Projects tab for your Organization, select and expand the relevant private repository, select a Target, and click the Settings cog. This opens the Project page.

2. On the Project page, apply unique settings for that specific Project. Select the Settings tab in the upper right and the Github integration __ option in the left sidebar.

3. Go to the Pull request assignees for private repos section at the bottom of the page and choose to Inherit from integration settings or Customize only for this Project.

4. Ensure Auto-assign PRs for this private Project is enabled.

5. Choose to assign PRs to the last user to change the manifest file or named contributors.

Auto-assign PRs for this private Project

How to disable the GitHub integration

The GitHub SCM integration leverages the OAuth app integration. If you integrated GitHub without using Snyk Broker, you can disconnect it by following these steps:

1. In GitHub, log in to the GitHub account that you used to create the integration.

2. Go to your GitHub account settings and select the Applications option in the left sidebar.

3. Select the Authorized OAuth Apps tab. You can also reach the Authorized OAuth Apps tab directly.

4. Find the Snyk entry, click the three (3) dots on the right, and select Revoke.

Revoke OAuth authorization

Revoking this access effectively disconnects Snyk’s access to that GitHub account.

• Existing imported snapshots will persist in Snyk and continue to be re-scanned based on the existing snapshots until deleted.

• Snyk will no longer be able to import new Projects from the GitHub integration and will no longer re-scan on new code merges.

In addition, you must confirm that Snyk is not enabled on any existing Branch protection rules.

Note that branch protection is active only after a PR has been raised.

1. From the main page of your GitHub repository, go to Settings > Branches > Branch protection rules.

2. Ensure there are no Status checks found in the last week for this repository.

A disconnected GitHub integration will still appear as configured in the Integrations menu of the Snyk UI. However, clicking on the integration settings will show that it is not connected. In this case, the "configured" integration can safely be ignored.

Migrate to the GitHub Enterprise integration

Before deleting Snyk Projects imported using the GitHub integration, consider the impact on reporting. If you decide to delete Projects, and none remain for a Target, delete the Target too. For details, contact your Snyk account team or Snyk support.

Before you configure and Import Projects using the GitHub Enterprise integration, Snyk recommends removing all Projects imported using the GitHub integration. This avoids having duplicate Snyk Projects.

You can remove Projects imported using the GitHub integration manually by removing the Projects from Snyk. However, depending on how many Projects you have already imported using the GitHub integration, it may be easier for you to create a new Snyk Organization.

If you have already created multiple Snyk Organizations and Projects have been imported from GitHub to each Organization, it may be easier to re-create the Snyk Organizations to use the Snyk GitHub Enterprise integration than to update each one manually. If you choose to do this, you can copy integration settings from an existing Organization to avoid having to re-configure other integrations.

Migration steps

If you already have multiple Snyk Organizations with Projects imported using the GitHub integration, follow these steps to migrate from GitHub integration to GitHub Enterprise integration.

1. Create a new Snyk Organization that will be used as the template for all others. You can copy integration settings from an existing Organization if required.

2. In this new template Organization, set up the Snyk GitHub Enterprise integration using the steps on the page GitHub Enterprise integration. The dedicated GitHub service account in those steps is a separate user account that you will use as the connection between Snyk and GitHub.

3. When the Snyk GitHub Enterprise integration is configured, you can import a Project to your template Organization to test that the integration is working as expected.

4. You can now create new Organizations that will replace the existing Organizations that were configured using the GitHub integration. As you create each new Organization, ensure that you copy the integration settings from this template Organization so that the GitHub Enterprise integration is available.

5. Now that your new Organizations are created, you can import your Projects, choosing the GitHub Enterprise integration when you select the source.

6. You can now remove the previous Organizations that were configured using the GitHub integration.

You may want to disconnect your GitHub integration to avoid unintentionally importing Projects using the GitHub integration in the future. Because the GitHub integration is configured per user account, rather than per Organization, each user who has set up the GitHub integration must complete this disconnection process individually.
