The Kubernetes component PKI must be owned by root.
An XCCDF Rule
Description
The Kubernetes PKI directory contains all certificates (.crt files) supporting secure network communications in the Kubernetes Control Plane. If these files can be modified, data traversing within the architecture components would become unsecure and compromised. Many of the security settings within the document are implemented through this file.
