Security incidents can occur even when companies follow protocols, as seen in the recent Uber breach where an 18-year-old used social engineering to bypass multi-factor authentication. To protect code from vulnerabilities, developers can use tools like Snyk's Code Checker to scan code before copying it into production environments. Snyk provides insights and advice on fixing vulnerabilities, categorizing them by severity, and offers a report card for teams to prioritize fixes based on resources and personnel. The tool also supports creating a pull request with a fix, allowing developers to learn more about the vulnerability and share details if necessary. Additionally, Snyk offers interactive lessons and a YouTube channel for expanding security expertise, as well as connecting with Snyk Ambassadors for security advice.
