Container Security

Preface

Many organizations are running applications in cloud native environments, using containers and orchestration to facilitate scalability and resilience. If you’re a member of the Operations, the DevOps, or even the DevSecOps team setting up these environments for your company, how do you know whether your deployments are secure? If you’re a security professional with experience in traditional server-based or virtual machine–based systems, how can you adapt your existing knowledge for container-based deployments? And as a developer in the cloud native world, what do you need to think about to improve the security of your containerized applications? This book delves into some of the key underlying technologies that containers and cloud native rely on, to leave you better equipped to assess the security risks and potential solutions applicable to your environment and to help you avoid falling into bad practices that will leave your technology deployments exposed.

In this book you will learn about many of the building block technologies and mechanisms that are commonly used in container-based systems, and how they are constructed in the Linux operating system. Together we will dive deep into the underpinnings of how containers work and how they communicate so that you are well versed not just in the “what” of container security but also, and more importantly, in the “why.” My goal in writing this book is to help you better understand what’s happening when you deploy containers. ...
