Attacking and Defending Insecure Direct Object References (IDOR) with Java EE is a comprehensive course designed for developers, security professionals, and Java enthusiasts to understand the risks associated with Insecure Direct Object References (IDOR) and learn how to mitigate them in Java EE applications. IDOR is a vulnerability that occurs when an attacker can access or modify resources they are not authorized to interact with, simply by manipulating input parameters such as URLs or request data. This course provides a hands-on, practical approach to both exploiting and defending against IDOR vulnerabilities within the context of Java EE applications.
