Auditing Web Services and APIs for Security Vulnerabilities

As modern applications rely heavily on interconnected web services and APIs, securing these endpoints is more critical than ever. This course introduces you to the structured process of identifying vulnerabilities before malicious actors can exploit them. You will transition from understanding basic web concepts to systematically analyzing web services using industry-standard auditing methodologies. By reading our detailed explanations and analyzing real-world code and configuration scenarios, you will build the practical mindset needed to uncover security gaps. What you'll learn: - Understand the fundamental architecture of web services, REST, and modern GraphQL APIs. - Differentiate and apply black box, white box, and grey box auditing methodologies. - Identify common vulnerabilities outlined in the OWASP API Security guidelines. - Analyze web service configurations and source code to spot authorization and authentication flaws. - Read and interpret security scan reports to prioritize remediation efforts. - Formulate actionable security recommendations to patch discovered vulnerabilities and harden services. The course begins with foundational web service concepts and API architectures before moving into hands-on auditing strategies and vulnerability analysis. You will work through structured text-based scenarios to apply auditing principles to real-world security challenges. This course is designed for beginner cybersecurity enthusiasts, web developers, and system administrators looking to enter the field of application security testing. No prior security auditing experience is required. Start reading today to build your skills in securing modern web services.
