APIs are the backbone of modern applications, but without proper security, they are vulnerable to DDoS attacks, data exfiltration, and business disruption. In this talk, we’ll explore key OWASP API security vulnerabilities, real-world breaches caused by misconfigured APIs, and mitigation strategies through proper security configurations.

We'll cover critical concepts like Broken Object Level Authorization (BOLA), Broken Function Level Authorization (BFLA), infrastructure security, and the importance of using Identity Providers (IDPs) instead of building custom authentication systems. Through live code examples, we’ll demonstrate common vulnerabilities and how to remediate them using robust validation and access control mechanisms.
