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.

Analyzing crypto-mining attacks

In this section, we will first provide a brief introduction to crypto-mining attacks, and then we will analyze some publicly disclosed crypto-mining attacks. We hope that you are aware of the crypto-mining attack patterns as well as the flaws that make the attack possible.

An introduction to crypto-mining attacks

Blockchain forms the basis for cryptocurrency. In short, blockchain is a chain of digital assets represented as blocks. These blocks have information about the transaction and who was involved in the transaction as a digital signature. Each cryptocurrency is associated with a blockchain. The process of verifying transactional records is called mining. Mining adds history to the blockchain to ensure that blocks cannot be modified in the future. Mining is designed to be resource-intensive to ensure the decentralized property of a blockchain. By successfully mining blocks, miners earn the transaction fee that is associated with the transaction...
