GitHub has security features that help keep code and secrets secure in repositories and across organizations. 某些功能可用于 所有存储库。 使用 GitHub Advanced Security 的企业可以使用其他功能。 有关详细信息，请参阅“关于 GitHub Advanced Security”。
The GitHub Advisory Database contains a curated list of security vulnerabilities that you can view, search, and filter. 有关详细信息，请参阅“在 GitHub Advisory Database 中浏览安全公告”。
Make it easy for your users to confidentially report security vulnerabilities they've found in your repository. For more information, see "Adding a security policy to your repository."
View alerts about dependencies that are known to contain security vulnerabilities, and choose whether to have pull requests generated automatically to update these dependencies. For more information, see "About Dependabot alerts" and "About Dependabot security updates."
Use Dependabot to automatically raise pull requests to keep your dependencies up-to-date. This helps reduce your exposure to older versions of dependencies. Using newer versions makes it easier to apply patches if security vulnerabilities are discovered, and also makes it easier for Dependabot security updates to successfully raise pull requests to upgrade vulnerable dependencies. For more information, see "About Dependabot version updates."
The dependency graph allows you to explore the ecosystems and packages that your repository depends on and the repositories and packages that depend on your repository.
You can find the dependency graph on the Insights tab for your repository. For more information, see "About the dependency graph."
The security overview shows which security features are enabled for the repository, and offers you the option of configuring any available security features that are not already enabled.
GitHub Advanced Security features are available for enterprises with a license for GitHub Advanced Security. The features are restricted to repositories owned by an organization. 有关详细信息，请参阅“关于 GitHub Advanced Security”。
Automatically detect security vulnerabilities and coding errors in new or modified code. Potential problems are highlighted, with detailed information, allowing you to fix the code before it's merged into your default branch. For more information, see "About code scanning."
Automatically detect tokens or credentials that have been checked into a repository. You can view alerts for any secrets that GitHub finds in your code, so that you know which tokens or credentials to treat as compromised. For more information, see "About secret scanning."
Show the full impact of changes to dependencies and see details of any vulnerable versions before you merge a pull request. For more information, see "About dependency review."
Review the security configuration and alerts for your organization and identify the repositories at greatest risk. For more information, see "About the security overview."
