CKs

CKS is an acronym with multiple meanings, depending on the context. In technology and IT, it most commonly denotes the Certified Kubernetes Security Specialist, a professional credential offered by the Cloud Native Computing Foundation (CNCF) in collaboration with the Linux Foundation.

The CKS certification validates expertise in securing Kubernetes environments. It covers topics such as cluster hardening, identity and access management, network security, secret management, supply chain security, logging and monitoring, and incident response. The exam is hands-on and performance-based, requiring candidates to complete tasks in a live Kubernetes cluster within a set time. Prerequisites are not strictly fixed, but many candidates pursue prior certifications such as the Certified Kubernetes Administrator (CKA) or gain equivalent practical experience before attempting CKS. Certification maintenance typically involves recertification or continuing education to remain in good standing.

Beyond IT, CKS can refer to a variety of other terms in different domains, including organizations, programs, or product names. Because it is an acronym with diverse uses, the precise meaning of CKS should be determined from the surrounding context. In general, when encountered in a professional or technical setting, CKS most often points to the Kubernetes security credential; elsewhere, it may denote unrelated entities that share the same initials.
