Web Security Fundamentals for Modern Developers

Web applications face constant security threats, making a strong understanding of defensive coding essential for every developer. This text-based course takes you from foundational security concepts to practical mitigation strategies, helping you write secure code and protect user data from the ground up. You will learn to think like an attacker to better defend your systems. What you'll learn: - Learn core security principles, including the CIA triad, threat modeling, and defense-in-depth. - Understand the OWASP Top 10 vulnerabilities, including Cross-Site Scripting (XSS), SQL Injection, and CSRF. - Implement secure authentication and modern authorization flows to protect user sessions. - Configure critical HTTP security headers, including Content Security Policy (CSP) and HSTS. - Apply secure cookie attributes and modern browser security controls to prevent session hijacking. - Practice identifying security vulnerabilities in written code examples and designing appropriate fixes. This course begins with key terminology and foundational concepts before moving into practical, step-by-step breakdowns of common web attacks and their defenses. It is designed specifically for beginner web developers and software engineers with no prior security background. Start reading today to build safer, more resilient web applications.
