This version of GitHub Enterprise was discontinued on 2022-06-03. No patch releases will be made, even for critical security issues. For better performance, improved security, and new features, upgrade to the latest version of GitHub Enterprise. For help with the upgrade, contact GitHub Enterprise support.

Configuring code scanning for your appliance

In this article

You can enable, configure and disable code scanning for your GitHub Enterprise Server instance. Code scanning allows users to scan code for vulnerabilities and errors.

Code scanning is available for organization-owned repositories where GitHub Advanced Security is enabled. For more information, see "About GitHub Advanced Security."

About code scanning

Code scanning is a feature that you use to analyze the code in a GitHub repository to find security vulnerabilities and coding errors. Any problems identified by the analysis are shown in GitHub Enterprise Server.

You can configure code scanning to run CodeQL analysis and third-party analysis. Code scanning also supports running analysis natively using GitHub Actions or externally using existing CI/CD infrastructure. The table below summarizes all the options available to users when you configure your GitHub Enterprise Server instance to allow code scanning using actions.

Type of analysisOptions for generating alerts
CodeQLUsing GitHub Actions (see "Setting up code scanning using actions") or running CodeQL analysis in a third-party continuous integration (CI) system (see "About CodeQL code scanning in your CI system").
Third‑partyUsing GitHub Actions (see "Setting up code scanning using actions") or generated externally and uploaded to GitHub Enterprise Server (see "Uploading a SARIF file to GitHub").

Checking whether your license includes GitHub Advanced Security

You can identify if your enterprise has a GitHub Advanced Security license by reviewing your enterprise settings. For more information, see "Enabling GitHub Advanced Security for your enterprise."

Prerequisites for code scanning

Running code scanning using GitHub Actions

Setting up a self-hosted runner

GitHub Enterprise Server can run code scanning using a GitHub Actions workflow. First, you need to provision one or more self-hosted GitHub Actions runners in your environment. You can provision self-hosted runners at the repository, organization, or enterprise account level. For more information, see "About self-hosted runners" and "Adding self-hosted runners."

You must ensure that Git is in the PATH variable on any self-hosted runners you use to run CodeQL actions.

Provisioning the actions for code scanning

If you want to use actions to run code scanning on GitHub Enterprise Server, the actions must be available on your appliance.

The CodeQL action is included in your installation of GitHub Enterprise Server. If GitHub Enterprise Server has access to the internet, the action will automatically download the CodeQL bundle required to perform analysis. Alternatively, you can use a synchronization tool to make the CodeQL analysis bundle available locally. For more information, see "Configuring CodeQL analysis on a server without internet access" below.

You can also make third-party actions available to users for code scanning, by setting up GitHub Connect. For more information, see "Configuring GitHub Connect to sync GitHub Actions" below.

Configuring CodeQL analysis on a server without internet access

If the server on which you are running GitHub Enterprise Server is not connected to the internet, and you want to allow users to enable CodeQL code scanning for their repositories, you must use the CodeQL action sync tool to copy the CodeQL analysis bundle from GitHub.com to your server. The tool, and details of how to use it, are available at https://github.com/github/codeql-action-sync-tool.

If you set up the CodeQL action sync tool, you can use it to sync the latest releases of the CodeQL action and associated CodeQL analysis bundle. These are compatible with GitHub Enterprise Server.

Configuring GitHub Connect to sync GitHub Actions

  1. If you want to download action workflows on demand from GitHub.com, you need to enable GitHub Connect. For more information, see "Enabling GitHub Connect."
  2. You'll also need to enable GitHub Actions for your GitHub Enterprise Server instance. For more information, see "Getting started with GitHub Actions for GitHub Enterprise Server."
  3. The next step is to configure access to actions on GitHub.com using GitHub Connect. For more information, see "Enabling automatic access to GitHub.com actions using GitHub Connect."
  4. Add a self-hosted runner to your repository, organization, or enterprise account. For more information, see "Adding self-hosted runners."

Running code scanning using the CodeQL CLI

If you don't want to use GitHub Actions, you should run code scanning using the CodeQL CLI.

The CodeQL CLI is a command-line tool that you use to analyze codebases on any machine, including a third-party CI/CD system. For more information, see "Installing CodeQL CLI in your CI system."

Running code scanning using the CodeQL runner

Note: The CodeQL runner is being deprecated. On GitHub Enterprise Server 3.0 and greater, you can install CodeQL CLI version 2.6.3 to replace CodeQL runner.

For more information, see the CodeQL runner deprecation. For information on migrating to CodeQL CLI, see "Migrating from the CodeQL runner to CodeQL CLI."

If you don't want to use GitHub Actions, you can run code scanning using the CodeQL runner.

The CodeQL runner is a command-line tool that you can add to your third-party CI/CD system. The tool runs CodeQL analysis on a checkout of a GitHub repository. For more information, see "Running code scanning in your CI system."
