Master CKS exam: RBAC, Pod Security, Falco runtime defense, supply chain security & audit logging on real Kubernetes
What you’ll learn
Harden Kubernetes clusters against the CIS Benchmark and pass kube-bench audits with zero critical failures
Design and implement least-privilege RBAC with service account scoping, role boundaries, and audit verification
Enforce Pod Security Standards, OPA Gatekeeper policies, and Kyverno rules to block insecure workloads at admission
Secure the container supply chain using Trivy image scanning, Cosign signing, and registry admission enforcement
Apply AppArmor profiles, Seccomp policies, and Linux capability drops to confine containers at the kernel level
Detect runtime attacks in real time using Falco rules and investigate incidents with Kubernetes audit logs and jq
Encrypt etcd secrets at rest, implement NetworkPolicy default-deny isolation, and configure mutual TLS between pods
Pass the CKS exam with confidence — time management strategy, must-know kubectl commands, and worked scenario walkthroughs
Requirements
Basic Kubernetes knowledge — comfortable with kubectl, pods, deployments, and namespaces (CKA-level or equivalent)
Familiarity with Linux command line — file editing, grep, systemctl, and reading log files
A practice cluster for hands-on labs — kind, minikube, or any kubeadm cluster works
No prior security certifications required — OSCP, CEH, or security experience is helpful but not needed
Description
The Certified Kubernetes Security Specialist (CKS) is the hardest Kubernetes certification — and the most valuable one for engineers who secure production clusters.
This course prepares you for the CKS exam and gives you the hands-on security engineering skills to back up the credential.
What you’ll build and configure
Harden a Kubernetes cluster against the CIS Benchmark from scratch. Design RBAC with true least privilege — scoped service accounts, bounded roles, no wildcard verbs. Enforce Pod Security Standards and OPA Gatekeeper policies that block insecure workloads before they ever reach a node. Lock containers down at the kernel level with AppArmor profiles, Seccomp policies, and capability drops.
Secure your container supply chain with Trivy image scanning, Cosign cryptographic signing, and admission policies that reject unsigned or vulnerable images. Isolate workloads with default-deny NetworkPolicies and mutual TLS. Encrypt etcd secrets at rest with AES-CBC or AES-GCM providers.
Detect attacks in real time with Falco behavioral rules. Investigate incidents with Kubernetes audit logs and jq forensic queries. Build the complete observability stack that makes every API call in your cluster traceable.
Exam preparation built in
Every module maps directly to a CKS exam domain. The final module covers time management strategy, must-know kubectl commands by domain, worked walkthroughs of the five most common examStandards and OPA Gatekeeper policies that block insecure workloads before they ever reach a node. Lock containers down at the kernel level with AppArmor profiles, Seccomp policies, and capability drops.
