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

Congratulations on reaching the end of this chapter – we have covered a lot of in-depth information on the practicality of attacking an API. At this point, you should have an appreciation for the fundamentals of many of the different attack types, and hopefully, you’re curious to try out some of these attacks yourself.

The attack techniques we covered align with the OWASP API Security Top 10 vulnerabilities, with a focus on authentication, authorization, and data-oriented attacks. By some measure, the most significant topic was the variety of ways in which authentication can be attacked and subverted in API systems — as a defender, this should be your first attack vector. Second only to authentication is the broad range of attacks that can be leveraged against authorization at both the object and function levels. We also learned key skills in attacking API data regarding both requests and responses. Finally, we covered a miscellany of attack types (injection...
