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

By now, you should appreciate the key challenges of securing APIs on microservices. The biggest challenge is the increased complexity of the systems compared to a comparable monolithic application implementation. Due to the increased demands to innovate and deliver functionality, it is safe to say that microservices are here to stay, and security will need to embrace this changing landscape. The recommended approach is to build upon a solid and secure foundation, starting with securing the containers that are used and then the Kubernetes clusters that provide the runtime environments. We learned how to secure the critical connectivity between clients and the gateway using TLS and between the microservices themselves using mTLS. The service mesh promises to secure communications seamlessly while providing integration tracing and monitoring.

Finally, we learned about the foundations of zero trust, which is a key philosophy for ensuring strong access control in a complex, distributed...
