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.

In this long chapter, we covered Kubernetes auditing, high availability for a Kubernetes cluster, managing secrets with Vault, detecting anomalous activities with Falco, and conducting forensics with CRIU and Sysdig. Though you may find it will take quite some time to get familiar with all the practices and tools, defense in depth is a huge topic and it is worth digging deeper into security so that you may build up a stronger fence for your Kubernetes cluster.

Most of the tools we talked about are easy to install and deploy. I would encourage you to try them out: add your own Kubernetes audit rules, use Vault to manage secrets in Kubernetes clusters, build your own Falco rules to detect anomalous behavior because you know your cluster better than anyone else, and use Sysdig to collect all the forensics data. Once you get familiar with all of these tools, you should feel confident that your Kubernetes cluster is a bit more under control.

In the next chapter, we're...
