• 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
