Triage and Remediation

​
Remediation

Using Console

Automated AAC auditing has been modified to allow CIS-CAT to input a variable for the <PATH>/<FILENAME> of the kubelet config file. Please set $kubelet_config=<PATH> based on the file location on your system for example: export kubelet_config=/etc/kubernetes/kubelet.conf To perform the audit manually: Run the below command (based on the file location on your system) on each worker node. For example, stat -c %U %G /etc/kubernetes/kubelet.conf Verify that the ownership is set to root:root.
