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.

Chapter 12: Analyzing and Detecting Crypto-Mining Attacks

Crypto-mining attacks are becoming more notable as blockchain and cryptocurrency are becoming more and more popular. Cryptocurrency is earned as the transaction fee of decentralized transactions on a blockchain for utilizing compute resources. The process of earning cryptocurrency for validating transactions using compute resources is called crypto-mining and is conducted by a software called a crypto-miner. Security researchers have found hacking incidents related to various crypto-miner binaries running within victims' infrastructures. The default openness of Kubernetes clusters and the availability of the extensive compute power required for mining makes Kubernetes clusters a perfect target for crypto-mining attacks. The complexity of Kubernetes clusters also makes crypto-mining activities hard to detect.
