Understanding the CKS Certification

The Certified Kubernetes Security Specialist (CKS) program provides assurance that a CKS possesses the skills, knowledge, and competence needed to implement best practices for securing container-based applications and Kubernetes platforms. This includes securing applications during build, deployment, and runtime. To be eligible for the CKS exam, candidates must hold the Certified Kubernetes Administrator (CKA) certification, making it a natural progression for experienced Kubernetes practitioners.

Who Is the CKS certification for?

A Certified Kubernetes Security Specialist is not just any Kubernetes professional. To earn this title, one must already be a CKA-certified expert. The CKS certification is tailored for accomplished Kubernetes practitioners who aim to demonstrate their proficiency in securing container-based applications and Kubernetes platforms during various phases – from the initial build to deployment and runtime.

About the CKS Certification

The CKS certification is a performance-based exam that challenges candidates' knowledge of Kubernetes and cloud security in a real-world, simulated environment. To attempt the CKS exam, candidates must have already passed the CKA exam, ensuring they possess a strong foundation in Kubernetes administration. Additionally, the CKA certification must be active (non-expired) on the date the CKS exam is scheduled, emphasizing the importance of continuous learning and certification maintenance.

What Does It Demonstrate?

Earning a CKS certification is not just a badge of honor; it's a testament to a candidate's ability to secure container-based applications and Kubernetes platforms during build, deployment, and runtime. With this certification, you prove your capability to perform these critical tasks professionally, adding immense value to your career and the organizations you work for.

Domains & Competencies

The CKS exam covers a range of domains and competencies, each vital in ensuring the security of Kubernetes environments. Here's a breakdown of the key areas tested in the exam:

Cluster Setup – 10%

  • Use Network security policies to restrict cluster-level access.
  • Employ CIS benchmarks to review the security configuration of Kubernetes components.
  • Properly configure Ingress objects with security controls.
  • Protect node metadata and endpoints.
  • Minimize the use of GUI elements.
  • Verify platform binaries before deploying.

Cluster Hardening – 15%

  • Restrict access to the Kubernetes API.
  • Utilize Role-Based Access Controls (RBAC) to minimize exposure.
  • Exercise caution when using service accounts.
  • Keep Kubernetes updated to mitigate vulnerabilities.

System Hardening – 15%

  • Minimize the host OS footprint to reduce the attack surface.
  • Restrict IAM roles.
  • Minimize external network access.
  • Employ kernel hardening tools like AppArmor and seccomp.

Minimize Microservice Vulnerabilities – 20%

  • Establish appropriate OS-level security domains.
  • Effectively manage Kubernetes secrets.
  • Implement container runtime sandboxes in multi-tenant environments.
  • Ensure pod-to-pod encryption using mTLS.

Supply Chain Security – 20%

  • Minimize the base image footprint.
  • Secure your supply chain with whitelisted registries and image signing.
  • Use static analysis for Kubernetes resources and Docker files.
  • Scan images for known vulnerabilities.

Monitoring, Logging, and Runtime Security – 20%

  • Conduct behavioral analytics of system activities at both the host and container levels.
  • Detect and respond to threats at all stages of an attack.
  • Perform deep analytical investigations to identify security threats.
  • Ensure the immutability of containers at runtime.
  • Use audit logs to monitor access and actions.

The CKS Exam Experience

The CKS exam is an online, proctored, performance-based test. Candidates have 2 hours to complete multiple tasks using the command line in a Kubernetes environment. To help candidates prepare for the exam, each CKS exam registration includes two attempts in an exam simulator provided by Killer.sh, a valuable resource to refine your skills.


To reiterate, the prerequisites for the CKS certification are as follows:

  • Active (non-expired) CKA certification is a mandatory prerequisite.
  • The CKS exam may be purchased but not scheduled until CKA certification has been achieved.

Your Path to Kubernetes Security Excellence

The Certified Kubernetes Security Specialist (CKS) certification is the ultimate validation of your expertise in securing container-based applications and Kubernetes platforms. By obtaining the CKS certification, you distinguish yourself as a Kubernetes professional capable of ensuring the utmost security at every stage of your deployment. Plus, with the rising importance of Kubernetes in modern IT, this certification can significantly enhance your career prospects.
