Edit the Kubernetes API Server manifest file in the /etc/kubernetes/manifests directory on the Kubernetes Master Node. Set the value of "--tls-min-version" to either "VersionTLS12" or higher.

Check Contents

Change to the /etc/kubernetes/manifests directory on the Kubernetes Master Node. Run the command:

grep -i tls-min-version *

If the setting tls-min-version is not configured in the Kubernetes API Server manifest file or it is set to "VersionTLS10" or "VersionTLS11", this is a finding.
