Ensure that Kubernetes PKI key files have permissions of 600.


Kubernetes makes use of a number of key files as part of the operation of its components. The permissions on these files should be set to 600 to protect their integrity and confidentiality.




Run the below command (based on the file location on your system) on the Control Plane node. For example,

chmod -R 600 /etc/kubernetes/pki/*.key

Default Value:

By default, the keys used by Kubernetes are set to have permissions of 600
