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

This chapter focused on the critical topic of securing your languages and frameworks when developing APIs. Many of the most serious vulnerabilities we covered in this book originate from vulnerable code implementations or misconfigurations of frameworks. It is vital for the reader to understand the best practices for secure coding and safe framework usage.

First, we examined how to manage the design-first process in practice, covering the important topic of incorporating the OpenAPI definitions in the development lifecycle to ensure that the definition is the source of truth for the API and that all API code is derived from the definition. To do this, we examined two different code-generation tools: Swagger Codegen and the OpenAPI Generator. For the latter, we took a deep dive into understanding how to use it to generate secure server code stubs for various languages. As an API developer, you should become familiar with the fundamentals of generating server implementations...
