Ensure that the --secure-port argument is not set to 0 (API Server)
Do not disable the secure port. The secure port is used to serve https with authentication and authorization. If you disable it, no https traffic is served and all traffic is served unencrypted.
Risk Level: High
Cloud Entity: Pods
CloudGuard Rule ID: D9.K8S.NET.08
Covered by Spectral: Yes
Category: Compute
GSL LOGIC
KubernetesPod where labels contain [value='kube-apiserver'] and namespace = 'kube-system' should have spec.containers with [(parsedArgs contain [key like 'secure-port' and value > 0]) or (parsedArgs contain-none [key like 'secure-port'])]
REMEDIATION
Edit the API server pod specification file $apiserverconf
on the master node and either remove the --secure-port parameter or
set it to a different (non-zero) desired port.

Pods are the smallest deployable units of computing that can be created and managed in Kubernetes.A Pod is a group of one or more containers (such as Docker containers), with shared storage/network, and a specification for how to run the containers.
