Introduction to API Security and Common Attack Methods

APIs are the backbone of modern web applications, making them prime targets for malicious actors. Understanding how attackers exploit these interfaces is the first step in building secure software. In this comprehensive text-only course, you will transition from a security novice to understanding the core mechanics of API vulnerabilities. You will learn to think like an attacker to identify flaws in RESTful APIs, analyze security risks, and apply fundamental defensive strategies to protect data. What you'll learn: - Understand foundational API concepts, REST architecture, and key security terminology - Identify common API vulnerabilities, including broken object-level authorization and improper assets management - Analyze JWT and authentication flaws to prevent unauthorized access - Explore rate limiting and throttling mechanisms to defend against denial-of-service attempts - Practice evaluating API endpoints through structured written scenarios and conceptual exercises - Discover modern defensive patterns to secure API gateways and handle input validation The course begins with essential API definitions and security concepts before guiding you through the OWASP API Security Top 10 vulnerabilities. You will read detailed breakdowns of exploit techniques and walk through step-by-step conceptual defense strategies. This course is designed for beginner developers, aspiring penetration testers, and security enthusiasts who want a solid foundation in API security. No prior security experience or advanced programming knowledge is required. Start reading today to build your foundational knowledge of API security and protect modern web applications.
