Adopting Zero Trust in Kubernetes: The Fundamentals

This article outlines how organizations can apply zero-trust principles to Kubernetes environments: it reviews the historical context and recent government guidance, recommends using Kubernetes network policies for micro-segmentation, workload identity (e.g., SPIFFE) and service mesh (e.g., Linkerd) for service-to-service authentication/authorization, and suggests proxy-based controls for user-to-service access; it stresses that moving to zero trust is a gradual process and only part of an overall security strategy.
