Defending APIs

By: Colin Domoney

Overview of this book

Along with the exponential growth of API adoption comes a rise in security concerns about their implementation and inherent vulnerabilities. For those seeking comprehensive insights into building, deploying, and managing APIs as the first line of cyber defense, this book offers invaluable guidance. Written by a seasoned DevSecOps expert, Defending APIs addresses the imperative task of API security with innovative approaches and techniques designed to combat API-specific safety challenges. The initial chapters are dedicated to API building blocks, hacking APIs by exploiting vulnerabilities, and case studies of recent breaches, while the subsequent sections of the book focus on building the skills necessary for securing APIs in real-world scenarios. Guided by clear step-by-step instructions, you’ll explore offensive techniques for testing vulnerabilities, attacking, and exploiting APIs. Transitioning to defensive techniques, the book equips you with effective methods to guard against common attacks. There are plenty of case studies peppered throughout the book to help you apply the techniques you’re learning in practice, complemented by in-depth insights and a wealth of best practices for building better APIs from the ground up. By the end of this book, you’ll have the expertise to develop secure APIs and test them against various cyber threats targeting APIs.

Summary

It was a long journey through this chapter—by now, you will have a strong understanding of flaws, vulnerabilities, and threats and how they present a risk to your APIs. The key vulnerabilities that affect APIs include broken object-level and function-level authorization, broken authentication, data vulnerabilities, and finally, implementation and configuration vulnerabilities. Even if your API is free of vulnerabilities, it can still be abused or susceptible to business logic attacks.

While this chapter has focused on the theoretical nature of vulnerabilities, we are about to see just how easily these vulnerabilities can result in major breaches as we take a deep dive into twelve recent API breaches.
