Learn Kubernetes Security
Secure your container environment against cyberattacks and deliver robust deployments with this practical guide Key FeaturesExplore a variety of Kubernetes components that help you to prevent cyberattacksPerform effective resource management and monitoring with Prometheus and built-in Kubernetes toolsLearn techniques to prevent attackers from compromising applications and accessing resources for crypto-coin miningBook Description Kubernetes is an open source orchestration platform for managing containerized applications. Despite widespread adoption of the technology, DevOps engineers might be unaware of the pitfalls of containerized environments. With this comprehensive book, you'll learn how to use the different security integrations available on the Kubernetes platform to safeguard your deployments in a variety of scenarios. Learn Kubernetes Security starts by taking you through the Kubernetes architecture and the networking model. You'll then learn about the Kubernetes threat model and get to grips with securing clusters. Throughout the book, you'll cover various security aspects such as authentication, authorization, image scanning, and resource monitoring. As you advance, you'll learn about securing cluster components (the kube-apiserver, CoreDNS, and kubelet) and pods (hardening image, security context, and PodSecurityPolicy). With the help of hands-on examples, you'll also learn how to use open source tools such as Anchore, Prometheus, OPA, and Falco to protect your deployments. By the end of this Kubernetes book, you'll have gained a solid understanding of container security and be able to protect your clusters from cyberattacks and mitigate cybersecurity threats. What you will learnUnderstand the basics of Kubernetes architecture and networkingGain insights into different security integrations provided by the Kubernetes platformDelve into Kubernetes' threat modeling and security domainsExplore different security configurations from a variety of practical examplesGet to grips with using and deploying open source tools to protect your deploymentsDiscover techniques to mitigate or prevent known Kubernetes hacksWho this book is for This book is for security consultants, cloud administrators, system administrators, and DevOps engineers interested in securing their container deployments. If you're looking to secure your Kubernetes clusters and cloud-based deployments, you'll find this book useful. A basic understanding of cloud computing and containerization is necessary to make the most of this book.

Securing, observing, and troubleshooting containerized workloads on Kubernetes can be daunting. It requires a range of considerations, from infrastructure choices and cluster configuration to deployment controls and runtime and network security. With this practical book, you'll learn how to adopt a holistic security and observability strategy for building and securing cloud native applications running on Kubernetes. Whether you're already working on cloud native applications or are in the process of migrating to its architecture, this guide introduces key security and observability concepts and best practices to help you unleash the power of cloud native applications. Authors Brendan Creane and Amit Gupta from Tigera take you through the full breadth of new cloud native approaches for establishing security and observability for applications running on Kubernetes. Learn why you need a security and observability strategy for cloud native applications and determine your scope of coverage Understand key concepts behind the book's security and observability approach Explore the technology choices available to support this strategy Discover how to share security responsibilities across multiple teams or roles Learn how to architect Kubernetes security and observability for multicloud and hybrid environments
Learning Kubernetes Security
Get practical, hands-on experience in Kubernetes security-from mastering the fundamentals to implementing advanced techniques to safeguard your Kubernetes deployments against malicious threats Key Features Understand Kubernetes security fundamentals through real-world examples of threat actor tactics Navigate the complexities of securing container orchestration with practical, expert insights Deploy multiple Kubernetes components, plugins, and third-party tools to proactively defend against cyberattacks Purchase of the print or Kindle book includes a free PDF eBook Book Description With readily available services, support, and tools, Kubernetes has become a foundation for digital transformation and cloud-native development, but it brings significant security challenges such as breaches and supply chain attacks. This updated edition equips you with defense strategies to protect your applications and infrastructure while understanding the attacker mindset, including tactics like container escapes and exploiting vulnerabilities to compromise clusters. The author distills his 25+ years of experience to guide you through Kubernetes components, architecture, and networking, addressing authentication, authorization, image scanning, resource monitoring, and traffic sniffing. You’ll implement security controls using third-party plugins (krew) and tools like Falco, Tetragon, and Cilium. You’ll also secure core components, such as the kube-apiserver, CoreDNS, and kubelet, while hardening images, managing security contexts, and applying PodSecurityPolicy. Through practical examples, the book teaches advanced techniques like redirecting traffic from misconfigured clusters to rogue pods and enhances your support incident response with effective cluster monitoring and log analysis. By the end of the book, you'll have a solid grasp of container security as well as the skills to defend your clusters against evolving threats. What you will learn Implement Kubernetes security best practices, from threat detection to network protection Build strong security layers and controls using core Kubernetes components Apply theory through hands-on labs to secure Kubernetes systems step by step Use security plugins and open-source tools to help mitigate container-based threats Set up monitoring and logging to quickly detect and respond to cybersecurity threats Analyze attacker tactics to build stronger cluster defense strategies Who this book is for This book is for DevOps and Platform teams managing Kubernetes environments. As security is a shared responsibility, it also addresses on-premises and cloud security professionals, as well as beginner and advanced incident responders. No expert knowledge is required; a basic tech background is all you need as this book covers Kubernetes fundamentals and security principles, delivering practical insights for anyone looking to stay current with modern tech and strengthen their security skills.
