Certified Kubernetes Security Specialist (CKS)

Kubernetes adoption expands the attack surface across clusters, workloads, images, secrets, APIs, and CI/CD pipelines. IT Directors should assign this professional-level CKS training to DevOps, platform engineering, Kubernetes administration, and DevSecOps practitioners who already have Kubernetes experience; the catalog positions it for DevOps professionals with three to five years of experience. Plan for about 27 hours per learner, plus time for hands-on reinforcement and exam review.

The course maps to practical security work: hardening clusters with CIS Benchmarks, limiting GUI and API access, securing secrets with Kubernetes and Vault, enforcing pod and resource policies, auditing cluster activity, scanning and signing container images, detecting runtime threats, and validating configurations with policy tools. For change management, Team Leads can sequence this training before production hardening initiatives, compliance reviews, or a CKS certification push so the team shares common tooling and terminology. CBT Nuggets Playlists and Team Reporting can help Training Managers assign the path and track progress across the team.

IT teams complete this CKS training to move Kubernetes security from ad hoc fixes to repeatable operating practices across clusters and pipelines.

• Reduce cluster risk: Apply CIS Benchmark concepts, pod security standards, admission controllers, and API priority controls to strengthen Kubernetes environments.
• Improve supply chain security: Scan Linux container images with Trivy, automate image scanning in GitHub Actions, and validate signed container images before deployment.
• Protect access and secrets: Limit Kubernetes GUI access, manage secrets securely, and use Vault and Teleport concepts to strengthen authentication and secret storage workflows.
• Increase detection and audit readiness: Work with Kubernetes events, audit logs, Falco runtime detection, Sumo Logic monitoring, and PowerShell-based log processing to support investigation and compliance evidence.

Knowledge

• Kubernetes security domains covered by the CKS exam, including cluster hardening, workload controls, runtime security, and supply chain protection.
• How network policies, Open Service Mesh, and access controls affect traffic flow and exposure inside Kubernetes environments.
• How CIS Benchmarks, pod security policies, pod security standards, admission controllers, Kyverno, Datree, OPA, and Rego relate to policy enforcement.
• How Kubernetes secrets, Vault, signed images, Trivy scans, and GitHub Actions contribute to secure deployment workflows.
• How audit logs, Kubernetes events, Falco, Sumo Logic, and PowerShell support monitoring and investigation.

Ability

• Evaluate Kubernetes cluster security using CIS Benchmark concepts and configuration validation approaches.
• Enforce workload and resource requirements with admission controllers, Kyverno policies, Open Policy Agent, Rego, and Datree.
• Secure container delivery by scanning images, signing images, and validating image signatures before deployment.
• Strengthen access and secret-management practices using Kubernetes controls, Vault, and Teleport concepts.
• Analyze Kubernetes events and audit logs, detect runtime threats with Falco, and process audit data with PowerShell.
