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 13: Learning from Kubernetes CVEs

Common Vulnerabilities and Exposures (CVEs) are identifications for publicly known security vulnerabilities and exposures that are found in popular applications. The CVE ID is made up of the CVE string followed by the year and the ID number for the vulnerability. The CVE database is publicly available and is maintained by the MITRE Corporation. The CVE entries include a brief description of each issue, which is helpful to understand the root cause and severity of the issue. These entries do not include technical details about the issue. CVEs are useful for IT professionals to coordinate and prioritize updates. Each CVE has a severity associated with it. MITRE uses a Common Vulnerability Scoring System (CVSS) to assign a severity rating to a CVE. It is recommended to patch high-severity CVEs immediately. Let's look at an example of a CVE entry on
