Implementing Kubernetes Pod Security Standards
Overview
Pod Security Standards (PSS) define three levels of security policies -- Privileged, Baseline, and Restricted -- enforced by the Pod Security Admission (PSA) controller built into Kubernetes 1.25+. PSA replaces the deprecated PodSecurityPolicy and provides namespace-level enforcement with three modes: enforce, audit, and warn.
When to Use
- When deploying or configuring implementing kubernetes pod security standards capabilities in your environment
- When establishing security controls aligned to compliance requirements
- When building or improving security architecture for this domain
- When conducting security assessments that require this implementation
Prerequisites
- Kubernetes cluster 1.25+ (PSA GA)
- kubectl configured with cluster-admin access
- Understanding of Linux capabilities and security contexts
