To get the most out of this book

Before starting with this book, it is expected that you have a preliminary understanding of cloud-native technologies such as Kubernetes and Terraform. This book was written to explain security solutions possible using the following cloud-native tools, and so it is expected that you should adopt a security mindset when learning about the tools or using them. This book has a lot of examples and references for you to follow and implement; it is expected that you don’t use the code, as provided, verbatim, as each environment is different. Instead, approach each chapter carefully, and apply your learnings in your own environment. I hope that you spend more time learning about the tool itself, as that provides a holistic understanding of what this book aims to achieve – cloud-native security.
