Configuring code scanning for your appliance

About code scanning

Code scanning 是一项功能，可用于分析 GitHub 仓库中的代� �，以查找安全漏洞和编� �错误。 分析发现的任何问题都显示在 GitHub Enterprise Server 中。

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.

分析类型	用于生成警报的选项
CodeQL	使用 GitHub Actions（请参阅“使用操作设置 code scanning”），或在第三方持续集成 (CI) 系统中运行 CodeQL 分析（请参阅“关于 CI 系统中的 CodeQL code scanning”）。
第三方	使用 GitHub Actions（请参阅“使用操作设置 code scanning”）或从外部生成并上� 到 GitHub Enterprise Server（请参阅“将 SARIF 文件上� 到 GitHub”）。

Checking whether your license includes GitHub Advanced Security

可通过查看企业设置来识别企业是否具有 GitHub Advanced Security 许可证。 有关详细信息，请参阅“为企业启用 GitHub 高级安全性”。

Prerequisites for code scanning

• A license for GitHub Advanced Security (see "About billing for GitHub Advanced Security")

• Code scanning enabled in the management console (see "Enabling GitHub Advanced Security for your enterprise")

• A VM or container for code scanning analysis to run in.

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 both GitHub Enterprise Server 3.2 and your GitHub Actions runner have access to the internet, the action will automatically download the CodeQL 2.6.3 bundle required to perform analysis. Alternatively, you can use a synchronization tool to make the latest released version of 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

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."
