Overview of this book

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.

Introduction to threat modeling

Threat modeling is a process of analyzing the system as a whole during the design phase of the software development life cycle (SDLC) to identify risks to the system proactively. Threat modeling is used to think about security requirements early in the development cycle to reduce the severity of risks from the start. Threat modeling involves identifying threats, understanding the effects of each threat, and finally developing a mitigation strategy for every threat. Threat modeling aims to highlight the risks in an ecosystem as a simple matrix with the likelihood and impact of the risk and a corresponding risk mitigation strategy if it exists.

After a successful threat modeling session, you're able to define the following:

  1. Asset: A property of an ecosystem that you need to protect.
  2. Security control: A property of a system that protects the asset against identified risks. These are either safeguards or countermeasures against the risk...
