APIs are increasingly targeted by cyberattacks, and many applications remain vulnerable due to insufficient security awareness. The OWASP API Security Top 10 provides a valuable framework to identify and address the most common and critical risks to API security. In this course, Dr. Sunny Wear will guide you through real-world API attacks and teach you actionable methods for securing your APIs, ensuring that you can mitigate risks before they become threats.
