Learn CKS Training

Prepare for the Certified Kubernetes Security Specialist (CKS) exam with a structured, hands-on learning path. This roadmap focuses on practical Kubernetes security across cluster and system hardening, minimizing microservice vulnerabilities, supply chain security, and monitoring, logging, and runtime security, plus performance-based exam tasks and real-world cloud-native scenarios. Guided CKS courses, labs, and mock exam practice will be added over time to help you build skills aligned with CKS objectives.
