Kubernetes NetworkPolicy for namespace isolation is enforced by applying baseline templates that control ingress and egress traffic across multi-tenant deployments. This prevents unauthorized network access by restricting pod communication between namespaces.

Pod Security Standards enforce workload security by replacing deprecated PodSecurityPolicy with baseline, restricted, and privileged policies. They harden Kubernetes by preventing privileged container escalation and restricting capabilities through admission control.

RBAC for least-privilege access controls is configured by scoping Role and ClusterRole bindings to specific namespaces. This restricts unauthorized access by ensuring service accounts and users only receive the exact permissions required for their operations.

Yes, these Kubernetes security policies support integration with admission-control policy engines like OPA Gatekeeper and Kyverno. This enables automated policy template enforcement during deployment to block misconfigurations before they reach the cluster.

This Skill applies PodSecurityPolicy and Pod Security Standards specifically for production-grade Kubernetes environments. It provides structured reference templates to harden clusters against misconfigurations and unauthorized access in multi-tenant deployments.
