OWASP Web Application Security

This course introduces the world of web application security using the OWASP framework, helping you understand how applications are attacked and how to defend them using secure coding and security best practices. You’ll begin by exploring how modern web applications are structured and how attackers identify and exploit vulnerabilities. The course familiarizes you with the OWASP Top 10 risk categories, common attack patterns, and real-world security challenges. From there, you’ll move into the practical side of security analysis, examining vulnerabilities such as SQL injection, cross-site scripting (XSS), authentication flaws, and misconfigurations. You’ll learn how these vulnerabilities arise and how they impact application behavior, data security, and user trust. You will also gain hands-on exposure to dynamic security testing using OWASP ZAP, enabling you to analyze running applications, intercept traffic, and identify vulnerabilities through automated and real-time testing. The course then shifts to mitigation and defense. You’ll learn how to apply secure coding practices, implement proper input validation and output handling, and strengthen authentication, session management, and configuration security to reduce risk. By the end of this course, you will be able to: • Explain the fundamentals of web application security and the OWASP risk model. • Analyze common vulnerabilities such as injection attacks, XSS, and authentication flaws. • Identify how attackers exploit application weaknesses and assess their impact. • Perform dynamic vulnerability analysis using OWASP ZAP. • Apply secure coding techniques to prevent common web vulnerabilities. • Implement configuration hardening and defensive security practices. • Evaluate application risks and recommend structured mitigation strategies. Designed for aspiring application security professionals, developers, cybersecurity learners, and IT practitioners, this course provides a practical foundation for understan
