CKS Supply Chain Security Practice Question
Which of the following is a static analysis tool for Kubernetes manifests that can be used to find misconfigurations?
⚠ Common exam trap
The CKS exam often tests the distinction between tools that scan container images (like Trivy) versus tools that scan Kubernetes manifest files (like Kubesec), causing candidates to confuse vulnerability scanning with static configuration analysis.
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Kubesec
Kubesec is a static analysis tool specifically designed to evaluate Kubernetes manifests against a set of built-in security policies. It scans YAML or JSON resource definitions and assigns a risk score based on misconfigurations such as running containers as root, missing resource limits, or insecure capability assignments. This makes it the correct choice for identifying misconfigurations in Kubernetes manifests without executing them.
