Configuring advanced setup for code scanning

You can configure advanced setup for a repository to find security vulnerabilities in your code using a highly customizable code scanning configuration.

Wer kann dieses Feature verwenden?

Repositorybesitzerinnen, Organisationsbesitzerinnen, Sicherheitsmanagerinnen und Benutzerinnen mit der Administratorrolle

Code scanning is available for the following repository types:

  • Public repositories on GitHub.com
  • Organization-owned repositories on GitHub Team, GitHub Enterprise Cloud, or GitHub Enterprise Server, with GitHub Code Security enabled.

About advanced setup for code scanning

Advanced setup for code scanning is helpful when you need to customize your code scanning. By creating and editing a workflow file, you can define how to build compiled languages, choose which queries to run, select the languages to scan, use a matrix build, and more. You also have access to all the options for controlling workflows, for example: changing the scan schedule, defining workflow triggers, specifying specialist runners to use. For more information about GitHub Actions workflows, see Workflows.

You can also configure code scanning with third-party tools. For more information, see Configuring code scanning using third-party actions.

Wenn du die Codeüberprüfung mit mehreren Konfigurationen ausführst, kann es passieren, dass eine Warnung mehrere Analyseursprünge aufweist. Wenn eine Warnung mehrere Analyseursprünge hat, kannst du den Status der Warnung für jeden Analyseursprung auf der Warnungsseite einsehen. Weitere Informationen finden Sie unter Informationen zu Codeüberprüfungswarnungen.

If you do not need a highly customizable code scanning configuration, consider using default setup for code scanning. For more information on eligibility for default setup, see Configuring default setup for code scanning.

Prerequisites

Your repository is eligible for advanced setup if it meets these requirements.

  • It uses CodeQL-supported languages or you plan to generate code scanning results with a third-party tool.
  • GitHub Actions sind aktiviert.
  • Es ist öffentlich sichtbar, oder GitHub Code Security ist aktiviert.

Configuring advanced setup for code scanning with CodeQL

You can customize your CodeQL analysis by creating and editing a workflow file. Selecting advanced setup generates a basic workflow file for you to customize using standard workflow syntax and specifying options for the CodeQL action. See Workflows and Customizing your advanced setup for code scanning.

  1. Navigieren Sie auf GitHub zur Hauptseite des Repositorys.

  2. Klicke unter dem Repositorynamen auf Settings. Wenn die Registerkarte „Einstellungen“ nicht angezeigt wird, wähle im Dropdownmenü die Option Einstellungen aus.

  3. Klicke im Abschnitt „Security“ der Randleiste auf Advanced Security.

  4. Scroll down to "Code Security", in the "CodeQL analysis" row select Set up , then click Advanced.

    Hinweis

    If you are switching from default setup to advanced setup, in the "CodeQL analysis" row, select , then click Switch to advanced. In the pop-up window that appears, click Disable CodeQL.

  5. To customize how code scanning scans your code, edit the workflow.

    Generally, you can commit the CodeQL-Analyseworkflow without making any changes to it. However, many of the third-party workflows require additional configuration, so read the comments in the workflow before committing.

    For more information, see Customizing your advanced setup for code scanning and CodeQL code scanning for compiled languages.

  6. Click Commit changes... to display the commit changes form.

    Screenshot of the form to create a new file. To the right of the file name, a green button, labeled "Commit changes...", is outlined in dark orange.

  7. In the commit message field, type a commit message.

  8. Choose whether you'd like to commit directly to the default branch, or create a new branch and start a pull request.

  9. Click Commit new file to commit the workflow file to the default branch or click Propose new file to commit the file to a new branch.

  10. If you created a new branch, click Create pull request and open a pull request to merge your change into the default branch.

In the suggested CodeQL-Analyseworkflow, code scanning is configured to analyze your code each time you either push a change to the default branch or any protected branches, or raise a pull request against the default branch. As a result, code scanning will now commence.

The on:pull_request and on:push triggers for code scanning are each useful for different purposes. See Customizing your advanced setup for code scanning and Auslösen eines Workflows.

Configuring code scanning using third-party actions

GitHub includes workflow templates for third-party actions, as well as the CodeQL action. Using a workflow template is much easier than writing a workflow unaided.

  1. Navigieren Sie auf GitHub zur Hauptseite des Repositorys.

  2. Klicke unter dem Repositorynamen auf Actions.

  3. If the repository has already at least one workflow configured and running, click New workflow to display workflow templates. If there are currently no workflows configured for the repository, go to the next step.

  4. In the "Choose a workflow" or "Get started with GitHub Actions" view, scroll down to the "Security" category and click Configure under the workflow you want to configure. You may need to click View all to find the security workflow you want to configure.

    Screenshot of the Security category of workflow templates. The Configure button and "View all" link are highlighted with an orange outline.

  5. Follow any instructions in the workflow to customize it to your needs. For more general assistance about workflows, click Documentation on the right pane of the workflow page.

  6. When you have finished defining your configuration, add the new workflow to your default branch.

Next steps

After your workflow runs successfully at least once, you are ready to start examining and resolving code scanning alerts. For more information on code scanning alerts, see Informationen zu Codeüberprüfungswarnungen and Bewerten von Warnungen der Codeüberprüfung für das Repository.

Learn how code scanning runs behave as checks on pull requests, see Filtern von Codescanbenachrichtigungen in Pull-Anforderungen.

You can find detailed information about your code scanning configuration, including timestamps for each scan and the percentage of files scanned, on the tool status page. For more information, see About the tool status page for code scanning.
