Securing, observing, and troubleshooting containerized workloads on Kubernetes can be a daunting task. It requires a comprehensive range of considerations, including infrastructure choices, cluster configuration, deployment controls, runtime and network security. This practical book aims to provide you with the knowledge and skills necessary to adopt a holistic security and observability strategy for building and securing cloud-native applications running on Kubernetes. Whether you are already working on cloud-native applications or are in the process of migrating to Kubernetes architecture, this guide will introduce key security and observability concepts and best practices to help you unlock the full potential of cloud-native applications.

Authors Brendan Creane and Amit Gupta from Tigera have extensively researched and authored this guide to cover the full breadth of new cloud-native approaches for establishing security and observability for applications running on Kubernetes.

In the first chapter, the authors delve into the importance of having a security and observability strategy for cloud-native applications. They explain why such a strategy is crucial and help you determine your scope of coverage. They also introduce key concepts behind the book's security and observability approach, which is based on a layered defense model and the principles of least privilege and continuous monitoring.

The second chapter explores the technology choices available to support this strategy. The authors discuss various tools and frameworks, such as Kubernetes security plugins, intrusion detection systems (IDS), log aggregation and analysis tools, and container security scanning tools. They provide an in-depth analysis of each tool, highlighting their features, benefits, and limitations.

In the third chapter, the authors guide you through the process of architecting Kubernetes security and observability for multicloud and hybrid environments. They discuss best practices for securing inter-cluster communication, managing access controls, and implementing network security measures. They also provide insights into how to share security responsibilities across multiple teams or roles and how to integrate security and observability into your development and operations processes.

The fourth chapter focuses on runtime security and observability. The authors discuss best practices for securing container images, enforcing container runtime policies, and monitoring container activity. They also provide tips and tricks for identifying and mitigating security vulnerabilities in your applications.

The fifth chapter covers network security and observability. The authors discuss best practices for securing Kubernetes clusters, implementing network segmentation, and monitoring network traffic. They also provide insights into how to detect and respond to security incidents and how to integrate network security with other security measures.

The final chapter summarizes the key concepts covered in the book and provides practical guidance for implementing a security and observability strategy for your cloud-native applications running on Kubernetes.

In conclusion, this practical book is a valuable resource for anyone who wants to build and secure cloud-native applications running on Kubernetes. Whether you are a seasoned Kubernetes administrator or a newcomer to the platform, this guide will help you develop the skills and knowledge necessary to establish a robust security and observability strategy. By following the best practices and principles outlined in this book, you can ensure that your applications are protected from threats, and you can gain valuable insights into their performance and behavior.
