About GitHub's security features
GitHub has security features that help keep code and secrets secure in repositories and across organizations. Some features are available for all repositories. Additional features are available to enterprises that use GitHub Advanced Security. 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 about advisory data, see "Browsing security vulnerabilities in the GitHub Advisory Database" in the GitHub.com documentation.
Available for all repositories
Security policy
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."
Dependabot alerts and security updates
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 alerts for vulnerable dependencies" and "About Dependabot security updates."
Dependabot version 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."
Dependency graph
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."
Available with GitHub Advanced Security
GitHub Advanced Security is available if your enterprise has a license for GitHub Advanced Security. It is restricted to repositories owned by an organization. For more information, see "About GitHub Advanced Security."
Code scanning
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."
Secret scanning
Automatically detect tokens or credentials that have been checked into a repository. View any secrets that GitHub has found in your code. You should treat tokens or credentials that have been checked into the repository as compromised. For more information, see "About secret scanning."
Dependency review
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."
