CERTIFICATION

The Certified Kubernetes Security Specialist (CKS) program provides assurance that a CKS has the skills, knowledge, and competence on a broad range of best practices for securing container-based applications and Kubernetes platforms during build, deployment and runtime. CKA certification is required to sit for this exam.

Who Is It For

A Certified Kubernetes Security Specialist (CKS) is an accomplished Kubernetes practitioner (must be CKA certified) who has demonstrated competence on a broad range of best practices for securing container-based applications and Kubernetes platforms during build, deployment and runtime.

About This Certification

CKS is a performance-based certification exam that tests candidates' knowledge of Kubernetes and cloud security in a simulated, real world environment. Candidates must have taken and passed the Certified Kubernetes Administrator (CKA) exam prior to attempting the CKS exam. CKS may be purchased but not scheduled until CKA certification has been achieved.
CKA Certification must be active (non-expired) on the date the CKS exam (including Retakes) is scheduled.

Scan images for known vulnerabilities

Monitoring, Logging and Runtime Security20%

Perform behavioral analytics of syscall process and file activities at the host and container level to detect malicious activities
Detect threats within physical infrastructure, apps, networks, data, users and workloads
Detect all phases of attack regardless where it occurs and how it spreads
Perform deep analytical investigation and identification of bad actors within environment
Ensure immutability of containers at runtime
Use Audit Logs to monitor access

Exam Details & Resources

This exam is an online, proctored, performance-based test that requires solving multiple tasks from a command line running Kubernetes. Candidates have 2 hours to complete the tasks.

Candidates who register for the Certified Kubernetes Security Specialist (CKS) exam will have 2 attempts (per exam registration) to an exam simulator, provided by Killer.sh.

Certified Kubernetes Security Specialist (CKS) candidates must have taken and passed the Certified Kubernetes Administrator (CKA) exam prior to attempting the CKS exam.

CKS may be purchased but not scheduled until CKA certification has been achieved.
CKA Certification must be active (non-expired) on the date the CKS exam (including Retakes) is scheduled.

The exam is based on Kubernetes v1.27
The CKS exam environment will be aligned with the most recent K8s minor version within approximately 4 to 8 weeks of the K8s release date
