Disable profiling, if not needed. Rationale: Profiling allows for the identification of specific performance bottlenecks. It generates a significant amount of program data that could potentially be exploited to uncover system and program details. If you are not experiencing any bottlenecks and do not need the profiler for troubleshooting purposes, it is recommended to turn it off to reduce the potential attack surface. Impact: Profiling information would not be available.
Edit the API server pod specification file /etc/kubernetes/manifests/kube-apiserver.yaml on the Control Plane node and set the below parameter. --profiling=false Default Value: By default, profiling is enabled.
