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.

Thinking like an attacker

The most powerful piece of advice I could offer any API builder or defender is to think like an attacker. As discussed in the opening section, developers may not have a perspective on or insight into how an attacker can exploit an API. Unfortunately, as we have seen in Chapter 4, Case Studies of Recent Breaches, it is all too easy to become the victim of an API attack.

So, where does a developer start on their journey toward building more secure APIs?

  • Equip yourself with a toolbox and set of resources: By far the most comprehensive list of API-security resources is the Awesome API Security GitHub repository: https://github.com/arainho/awesome-api-security.
  • Start with learning material: There are great tutorials on YouTube, and an API-security course is even available for free online. OWASP as always is a fantastic reference.
  • Test your own APIs: Use Postman and/or the reverse proxy tool to interact with your own APIs. Try to do things in...
