GitHub has security features that help keep code and secrets secure in repositories and across organizations. Some features are available for repositories on all plans. Additional features are available to enterprises that use GitHub Advanced Security. GitHub Advanced Security features are also enabled for all public repositories on GitHub.com. For more information, see "About GitHub Advanced Security."
The GitHub Advisory Database contains a curated list of security vulnerabilities that you can view, search, and filter. For more information, see "Browsing security vulnerabilities in the GitHub Advisory Database" and "About GitHub Security Advisories."
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."
Privately discuss and fix security vulnerabilities in your repository's code. You can then publish a security advisory to alert your community to the vulnerability and encourage community members to upgrade. For more information, see "About GitHub Security Advisories."
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."
For all public repositories, the security overview shows which security features are enabled for the repository, and offers the option to configure any available security features that are not currently enabled.
The following GitHub Advanced Security features are available and free of charge for public repositories on GitHub.com. Organizations that use GitHub Enterprise Cloud with a license for GitHub Advanced Security can use the full set of features in any of their repositories. For a list of the features available with GitHub Enterprise Cloud, see the GitHub Enterprise Cloud documentation.
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 leaked secrets across all public repositories. GitHub informs the relevant service provider that the secret may be compromised. For details of the supported secrets and service providers, see "Secret scanning patterns."
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."
