What you'll learn

Exceptional conditions in an application can be hard to find because they’re often surprising in their complexity and have a big impact on security.

In this course, OWASP: Mishandling of Exceptional Conditions, you'll learn to recognize and remediate the logic vulnerabilities that undermine application security.

First, you'll explore how exceptional conditions fit within the OWASP Top 10 and what makes logic bugs uniquely dangerous. Next, you'll examine the exceptional conditions themselves, understanding how and why each one can be exploited. Finally, you'll learn how to implement an array of defensive techniques. When you're finished with this course, you'll have the skills and knowledge needed to handle exceptional conditions in a way that keeps your applications safe.
