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

In this chapter, we have looked at various technologies that can be used to protect APIs at runtime; this is the shield-right approach to API security. Adding additional protection at runtime can add a further layer of protection to an API that can build upon the strong foundations of a secure design and implementation. Firstly, we looked at some basic techniques to harden the runtime environments of our APIs. WAFs play an important role in protecting web applications and APIs, particularly against some of the older attack methods. We then looked in detail at the vital role that API gateways and API management portals fulfill in securing APIs. In particular, we saw how an open source gateway can provide various protections at runtime, such as rate-limiting, IP address restriction, and JWT validation.

Dedicated API firewalls provide a dedicated layer 7 protection for APIs by enforcing OpenAPI contracts at runtime. Finally, it is important to monitor your API runtimes to identify...
