5 min readThe Certified Kubernetes Security Specialist (CKS) is an advanced, performance-based certification offered by the Linux Foundation and the Cloud Native Computing Foundation (CNCF). It is intended for professionals who already hold a valid Certified Kubernetes Administrator (CKA) certification, as a strong foundation in Kubernetes administration is a prerequisite for sitting the exam. The CKS focuses specifically on the security aspects of Kubernetes, covering everything from initial cluster hardening through to runtime threat detection.
Like the CKA and CKAD, the CKS is a fully hands-on exam conducted in a live terminal environment. Candidates are given two hours to complete a series of performance-based tasks on real Kubernetes clusters. There are no multiple-choice questions. The exam tests your ability to apply security best practices under time pressure, using the same tools and workflows you would use in a production environment.
To achieve certification, candidates must score at least 67%. The exam covers six weighted domains: Cluster Setup (10%), Cluster Hardening (15%), System Hardening (15%), Minimise Microservice Vulnerabilities (20%), Supply Chain Security (20%), and Monitoring, Logging and Runtime Security (20%). These domains span the full breadth of Kubernetes security, from network policies and CIS benchmarks to image scanning and audit logging.
Preparing for the CKS requires more than just theoretical knowledge. You need to be comfortable configuring Pod Security Admission, working with Open Policy Agent and Gatekeeper, using tools such as Falco, Trivy, and kubesec, and hardening the Kubernetes API server and node components. Familiarity with Linux security primitives, including seccomp profiles, AppArmor, and kernel capabilities, is also essential.
These practice question sets are structured around the official CKS exam domains to help you identify gaps in your knowledge and build confidence before exam day. Each question includes a detailed explanation so you can understand the reasoning behind secure configurations, not just the correct commands.
