What you'll learn

Broken access control flaws are among the most common and dangerous vulnerabilities in modern applications, often leading to data leaks, account compromise, and unauthorized actions. In this course, OWASP: Broken Access Control, you’ll learn to recognize, test, and prevent the most critical access control weaknesses defined in the latest OWASP Top 10. First, you’ll explore how access control works, why it fails, and how to spot broken patterns in real applications. Next, you’ll discover practical testing techniques—both manual and automated—for uncovering IDORs, privilege escalation paths, and other access control flaws. Finally, you’ll learn how to implement secure, scalable access control patterns that eliminate these vulnerabilities at their root. When you’re finished with this course, you’ll have the skills and knowledge of broken access control required to confidently identify, exploit, and remediate these issues in any application.
