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.

Summary

In this chapter, we went through a couple of the crypto-mining attacks that occurred over the last two years that brought a lot of attention to the need for securing containerized environments. Then, we showed you how to detect crypto-mining attacks with different open source tools. Last but not the least, we talked about how to defend your Kubernetes clusters against attacks in general by recapping what we discussed in previous chapters.

We hope you understand the core concepts of securing a Kubernetes cluster, which means securing the cluster provisioning, build, deployment, and runtime stages. You should also feel comfortable with starting to use Anchore, Prometheus, Grafana, and Falco.

As we know, Kubernetes is still evolving and it's not perfect. In the next chapter, we're going to talk about some known Kubernetes Common Vulnerabilities and Exposures (CVEs) and some mitigations that can protect your cluster against unknown variations. The purpose of the...
