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.

Implementation vulnerabilities

In the final portion of this chapter, we will cover the remaining vulnerabilities without going into a deep level of detail. Many of these vulnerabilities are not specific to APIs but affect many software systems, and there is already a body of knowledge in the industry on how to address these issues. I have included a Further reading section at the end of this chapter, and as always, the reader is well advised to consult the OWASP project, which maintains excellent guides and resources on these topics.

Injection

Injection vulnerabilities have plagued software systems for over two decades already; fortunately, it is a vulnerability class that can be totally eliminated by implementing patterns for secure coding. Injection attacks occur when a system trusts user input without validating it, allowing an attacker to launch attacks against underlying components such as databases, operating systems, and filesystems. Typical examples include SQL injection...
