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.

Understanding APIs

With our understanding of the role APIs play and the security challenges associated with them, let’s take a deeper look at how APIs work in much more detail. By the conclusion of this chapter, you will have a full understanding of how APIs work, starting with the transport protocol and the choice of APIs available to developers. The two central tenets of API security are authentication and authorization—we will cover these in detail to understand their pivotal role. Finally, you’ll understand how keys and tokens are used in ensuring the security and integrity of APIs and the identity of API clients.

In this chapter, we’re going to cover the following main topics:

  • The fundamentals of HTTP
  • The different types of APIs that are currently in use
  • Authentication best practices and methods
  • Authorization best practices and methods
  • Using tokens and keys
