Kubernetes Hardening & Pod Security

Deploying containers on Kubernetes without proper hardening exposes your internal cloud network to container breakout attacks and privilege escalation.

Key K8s Hardening Checkpoints

1. Enforce Pod Security Admission (PSA): Restrict containers from running as root or with privileged: true.
2. Restrict K8s RBAC Roles: Eliminate wildcard permissions (*) on secrets, configmaps, and pods.
3. Scan Container Base Images: Integrate Trivy or Snyk in your CI/CD pipeline to catch OS-level CVEs before cluster deployment.
4. Isolate Control Plane Access: Never expose the API server (:6443) publicly without strict IP whitelisting or VPN access.
