Mastering API Security Testing

APIs power today’s digital platforms—and are frequent targets for injection attacks, cross-site scripting, and other security vulnerabilities. This course guides you through a practical testing process to find and exploit flaws, ensure data integrity, and secure access for only authorized users. You'll also understand how components like an API gateway play a role in strengthening overall API security.

You’ll begin with foundational concepts like API types, attack surfaces, and authentication models, then move to practical testing using tools such as Postman, Burp Suite, and OWASP ZAP.

Core modules walk through the OWASP API Top 10, including Broken Object Level Authorization (BOLA), mass assignment, security misconfigurations, and more. Labs using Swagger UI, Docker, and vAPI provide guided exercises for practical learning.

You’ll also explore modern topics like AI in API attacks and defense, and how to embed testing into CI/CD pipelines. Case studies and bug bounty insights give you context from real-world API breaches.

• Scan and analyze API endpoints for flaws and misconfigurations
• Execute practical exploits like token manipulation and sensitive data exposure
• Harden APIs using authentication, rate limiting, and secure logging practices
• Use API security testing tools and automated tools for efficient assessments
• Apply OWASP API Security Top 10 guidelines and DAST (Dynamic Application Security Testing) methods
• Test API security by fuzzing inputs and sending crafted API requests
• Learn to write and submit professional reports on application programming interfaces for bug bounties or internal fixes

Whether you're validating authentication mechanisms or helping prevent major security risks, this course prepares you to secure and responsibly test modern APIs.
