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.

Active discovery

We will now look at various techniques for the active discovery of APIs in the real world. By active, we mean that we will interact with the API and/or its network by monitoring the traffic or directly accessing the API or its host.

Note – ensure that you have permission to access the computing resources

The use of active discovery using the tools and techniques described in this section may be against the terms and conditions of use of various services, ranging from your ISP to the relevant cloud hosting service. If you are unsure whether you are authorized to perform such scanning, you should err on the side of caution and seek explicit permission. In many cases, such scanning may also be against the applicable laws within your country, and any violations may have serious consequences. Fortunately, many of the scenarios described can easily be recreated in a laboratory environment that is totally under your control.
