Business Logic Vulnerability

Securing Business Logic: Identifying, Exploiting, and Mitigating Vulnerabilities in Web Applications

What you'll learn

Understanding Business Logic in Software Applications

Common Types of Business Logic Vulnerabilities

Identifying Business Logic Vulnerabilities

Security in the Software Development Lifecycle

Requirements

Basic Web Development Knowledge

Description

In this course, you will dive deep into the world of business logic vulnerabilities and learn how they can jeopardize the security of web applications. Business logic flaws occur when the core processes and rules governing an application's operation are incorrectly implemented, leaving room for exploitation. These vulnerabilities often go unnoticed, yet they can lead to severe consequences like unauthorized access, financial fraud, and system manipulation.Throughout the course, you'll explore the fundamentals of business logic, how these vulnerabilities arise, and real-world examples of attacks that exploit business logic flaws. You’ll gain hands-on experience in identifying these vulnerabilities within web applications, understanding how attackers manipulate business rules, and learning how to effectively mitigate these risks.By the end of the course, you’ll have the knowledge and skills to:Recognize common business logic vulnerabilities, such as privilege escalation, improper access control, and manipulation of business workflows.Use both manual and automated testing techniques to find vulnerabilities in web applications.Implement best practices to secure business logic and prevent exploitation.Understand the role of business logic in the overall security architecture of an application and how to protect it during development.This course is ideal for developers, security professionals, and anyone interested in securing applications from overlooked yet highly impactful vulnerabilities. Whether you're a beginner or have prior experience, you'll walk away with practical knowledge that can be applied immediately in real-world projects.
