Web Security Essentials: Mitigating Common Web Vulnerabilities

Web applications are constant targets for cyber threats, making security a fundamental skill for any modern developer. This text-based course provides a clear, step-by-step introduction to identifying and neutralizing the most common web security risks. By learning how vulnerabilities are exploited, you will gain the practical knowledge needed to defend your applications. You will progress from foundational security concepts to implementing industry-standard defenses in your own code. What you'll learn: - Understand core security terminology, threat modeling, and the principles of secure system design. - Detect and mitigate common vulnerabilities including Cross-Site Request Forgery (CSRF) and Cross-Site Scripting (XSS). - Prevent Man-in-the-Middle (MITM) attacks by securing data in transit using modern transport layer security. - Implement secure authentication flows, token management, and modern session-handling best practices. - Configure essential security headers, such as Content Security Policy (CSP), to protect your front-end applications. The course begins with foundational concepts and security terminology before diving into detailed explanations of vulnerability mechanics and written code examples for mitigation. This course is designed for beginner developers, system administrators, and anyone curious about web security. No prior security experience is required.
