Pod Security Standards: A Security-First Guide

Kubernetes Pod Security Standards TL;DR: I enforce PSS restricted on all production namespaces: runAsNonRoot: true , allowPrivilegeEscalation: false , all capabilities dropped, read-only root filesystem. Start with warn mode to find violations, then switch to enforce . This single change blocks the majority of container escape attacks. Imagine this: your Kubernetes cluster is humming along nicely, handling thousands of requests per second. Then, out of nowhere, you discover that one of your pods has been compromised. The attacker exploited a misconfigured pod to escalate privileges and access sensitive data. If this scenario sends chills down your spine, you're not alone. Kubernetes security is a moving target, and Pod Security Standards (PSS) are here to help. PSS is Kubernetes' answer to the growing need for solid, declarative security policies. They provide a framework for defining and enforcing security requirements for pods, ensuring that your workloads adhere to best practices. B
