Web Application Security Testing & Vulnerability Assessment

"|| Unofficial Course ||Master the essential principles and methodologies of web application security testing with this comprehensive course designed to take you from core concepts to professional security assessment and reporting. This course provides a structured understanding of how modern web applications are built, how security controls work, where common weaknesses occur, and how security professionals systematically evaluate applications for vulnerabilities. You will begin by developing a strong foundation in web application architecture and client-server communication, including HTTP and HTTPS protocols, headers, status codes, and the fundamental objectives of web application security testing. You will also explore the core principles of confidentiality, integrity, and availability and understand how these principles apply to modern web environments. The course then introduces established security testing methodologies and industry standards, including the OWASP Web Security Testing Guide (WSTG), Penetration Testing Execution Standard (PTES), and NIST SP 800-115. You will learn the differences between black-box, white-box, and gray-box testing approaches, along with how professional testers define engagement scope, establish rules of engagement, perform threat modeling, and distinguish between passive and active reconnaissance.A major part of the course focuses on authentication and session management. You will explore password-based authentication, multi-factor authentication, OAuth, common authentication design weaknesses, session architecture, cookies, tokens, expiration mechanisms, and important concepts surrounding session hijacking, session fixation, and Cross-Site Request Forgery (CSRF). The goal is to help you understand how authentication and session controls can be evaluated from a security testing perspective. You will also develop a strong under…
