A current guide to CKS, including the CKA prerequisite, 2-hour Kubernetes security performance format, Kubernetes v1.34 context, 67% passing score, and six security domain weights.
CKS validates practical Kubernetes security skills across cluster setup, hardening, host security, workload isolation, supply chain controls, and runtime detection. Preparation should be terminal-heavy and grounded in real security remediation tasks.
Use these points before scheduling the Linux Foundation CKS exam or starting Kubernetes security practice.
Linux Foundation requires CKS candidates to have taken and passed CKA before attempting CKS.
CKS is an online, proctored, performance-based exam with command-line Kubernetes security tasks.
Linux Foundation lists the CKS exam duration as 2 hours.
Linux Foundation currently lists the CKS product page as based on Kubernetes v1.34.
Linux Foundation FAQ lists 67% or above as the passing score for CKS.
Linux Foundation lists one retake and two exam simulator attempts with the CKS purchase.
CKS is a specialist exam, and Linux Foundation requires candidates to have passed CKA before attempting it. Confirm prerequisite status before buying or scheduling the exam.
Cluster Setup and Cluster Hardening together account for 30%. Practice NetworkPolicies, CIS benchmark review, Ingress TLS, metadata protection, binary verification, RBAC, service account hygiene, API restriction, and Kubernetes upgrades.
Minimize Microservice Vulnerabilities and Supply Chain Security together account for 40%. Review Pod Security Standards, Secrets, isolation, sandboxing, pod-to-pod encryption, base image minimization, SBOMs, permitted registries, artifact signing, and static analysis tools.
Monitoring, Logging and Runtime Security is 20%. Practice behavioral analytics, audit logs, identifying attack phases, investigating suspicious workload behavior, and enforcing immutability expectations at runtime.
Use this Certified Kubernetes Security Specialist (CKS) exam help page for exam-specific context, then compare the broader online exam help services page or contact HiraEdu if you need a direct handoff. This page stays focused on Certified Kubernetes Security Specialist (CKS) while the linked service pages cover broader exam support options.
Certified Kubernetes Security Specialist is a vendor-neutral certification created by the Linux Foundation and CNCF for Kubernetes practitioners who secure container-based applications and Kubernetes platforms during build, deployment, and runtime. CKS candidates must have taken and passed Certified Kubernetes Administrator before attempting CKS. The CKS exam is an online, proctored, performance-based exam with 2 hours to solve command-line tasks in a Kubernetes environment. Linux Foundation's current product page lists Kubernetes v1.34, 12 months of exam eligibility, one retake, two exam simulator attempts, a PDF certificate and digital badge, and certification validity of 2 years. Current domain weights are Cluster Setup 15%, Cluster Hardening 15%, System Hardening 10%, Minimize Microservice Vulnerabilities 20%, Supply Chain Security 20%, and Monitoring, Logging and Runtime Security 20%. The Linux Foundation FAQ lists a 67% passing score for CKS.
Yes. Linux Foundation requires Certified Kubernetes Security Specialist candidates to have taken and passed CKA before attempting CKS.
Linux Foundation lists the CKS exam duration as 2 hours.
Linux Foundation FAQ lists 67% or above as the passing score for CKS.
The current weights are Cluster Setup 15%, Cluster Hardening 15%, System Hardening 10%, Minimize Microservice Vulnerabilities 20%, Supply Chain Security 20%, and Monitoring, Logging and Runtime Security 20%.
Practice Kubernetes security tasks hands-on: RBAC, service accounts, NetworkPolicies, CIS benchmark checks, Ingress TLS, API and kubelet hardening, seccomp, AppArmor, Pod Security Standards, image and supply chain controls, audit logs, and runtime detection.
Confirm CKA status and check Linux Foundation candidate instructions for the current CKS Kubernetes minor version before your exam date.
Build study time around 15%, 15%, 10%, 20%, 20%, and 20% security domain weights.
Practice RBAC, service accounts, NetworkPolicies, Ingress TLS, CIS benchmark checks, kubelet and API restrictions, seccomp, AppArmor, and Pod Security Standards.
Work through image minimization, SBOM concepts, permitted registries, artifact signing, static analysis, audit policies, logs, runtime detection, and incident triage.
Run the included simulator attempts after enough hands-on practice to identify final speed and accuracy gaps.
Use the guide to self-serve, or talk to a coordinator if you need help mapping timelines, official requirements, or troubleshooting day-of logistics.
