GitHub has security features that help keep code and secrets secure in repositories and across organizations. Some features are available for all repositories and others are only available for public repositories and for repositories with a GitHub Advanced Security license.
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 alerts for vulnerable dependencies" and "About Actualizaciones de seguridad del Dependabot de GitHub."
Use Dependabot de GitHub 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 Actualizaciones de seguridad del Dependabot de GitHub to successfully raise pull requests to upgrade vulnerable dependencies. For more information, see "About Actualizaciones de versión para el Dependabot de GitHub."
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."
These features are available for all public repositories, and for private repositories owned by organizations with an Advanced Security license. For more information, see "About 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."
For private repositories, 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."
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."
