Testing Web Security Headers with Chrome Lighthouse

Securing web applications starts with understanding the vulnerabilities visible to the outside world. Many developers overlook basic security configurations, leaving their sites exposed to cross-site scripting and injection attacks. This text-based course guides you through the process of using Chrome Lighthouse to audit your website's security posture. You will learn how to analyze security headers, detect outdated JavaScript dependencies, and implement robust defensive configurations to protect your users. What you'll learn: - Understand the fundamentals of web security headers and how they prevent common browser-based attacks. - Run Chrome Lighthouse security audits to identify missing headers and vulnerable front-end libraries. - Configure essential HTTP headers including Content Security Policy, HSTS, and X-Frame-Options. - Analyze audit reports to pinpoint outdated third-party JavaScript packages containing known vulnerabilities. - Apply best practices for ongoing security monitoring and front-end vulnerability mitigation. You will start by learning core web security concepts and the role of HTTP response headers. From there, you will progress to executing Lighthouse audits, interpreting the security recommendations, and writing secure configuration rules through written explanations and practical examples. This course is designed for beginner web developers, QA testers, and security enthusiasts who want to learn the basics of web vulnerability scanning. No prior security experience is required.
