KCSA exam facts, domains and practice
The KCSA validates foundational knowledge of securing Kubernetes and the cloud native stack: cluster component security, threat modeling, platform security, and compliance frameworks. Multiple-choice, so it tests security reasoning rather than terminal speed.
Who this exam is for
Engineers and security folks who want a vendor-neutral cloud native security credential without a hands-on prerequisite, and the natural step before CKS.
