Welcome back to GitHub for Beginners, season three! So far this year, we’ve covered GitHub Issues and Projects, as well as GitHub Actions. This time around, we’re going to be talking a little bit about security, and what tools GitHub provides to help you keep your code secure. By the end of this post, you’ll understand how to fix vulnerabilities in your repository using built-in tools like secret scanning, Dependabot, code scanning, and Copilot Autofix.
Why security matters
Vulnerabilities are weaknesses in your code or the libraries you use that attackers can exploit. It’s important to realize that you inherit any risk from a library the moment you import it into your project, even though you didn’t write the vulnerable code yourself. This is why even small or brand-new projects can have vulnerabilities—almost all software relies on third-party packages.
GitHub makes finding and fixing these issues easier than ever with GitHub Advanced Security (GHAS), a suite of products that helps you improve and maintain the quality of your code. On public repositories, you have access to Dependabot, code scanning, secret scanning, and Copilot Autofix. If you want to learn even more about the different features, check out our documentation about GHAS. Or keep reading as we walk through enabling and using some of these features.
