XSS Vulnerabilities: Detection and Defense

Web applications are constantly targeted by malicious actors. Cross-Site Scripting (XSS) remains one of the most prevalent and dangerous client-side vulnerabilities. This course will equip you with the foundational knowledge and practical skills to recognize, analyze, and effectively mitigate various types of XSS attacks, enhancing the security posture of any web application. What you'll learn: * Learn the fundamental principles of Cross-Site Scripting (XSS) and its impact on web security. * Understand the different types of XSS vulnerabilities: Stored, Reflected, and DOM-based. * Practice identifying XSS vulnerabilities through common attack vectors and payloads. * Apply robust mitigation techniques, including input validation, output encoding, and Content Security Policy (CSP). * Configure and implement secure coding practices to prevent XSS in modern web development. * Analyze real-world examples of XSS exploits and their prevention strategies. Beginning with core concepts and terminology, the course progressively introduces common attack scenarios and then delves into practical defense mechanisms, concluding with best practices for secure web development. This course is designed for web developers, security enthusiasts, and anyone new to web application security who wants to build a strong foundation in protecting against XSS attacks.
