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 took us on a complete journey from zero knowledge of a target right through to being able to determine the version of the database used. The passive reconnaissance techniques principally used Google and the query operators, as well as the Shodan database, to determine a range of likely candidate targets for exploration.

We learned how to use active reconnaissance to actively focus on the API implementations on the hosts by examining their behavior under live probing using nmap or Massscan, while OWASP ZAP can provide a wealth of insight using spider scanning. Finally, we learned how to use information leakage to gain insight into the inner details of the implementation, allowing us to understand details such as the host OS and database.

By conducting a thorough discovery phase, you will have placed yourself in a perfect position to move on to the final chapter in the section—on attacking APIs.
