The --auto-tls argument is set to True misconfiguration detected in code

Rule Details

Cortex AppSec Rule ID	APPSEC_K8S_118
Category - Subcategory	Kubernetes - Native Security Controls
Provider	OTHER
Severity	HIGH
Framework	Helm, Kubernetes, Kustomize

Impact

Do not use self-signed certificates for TLS. etcd is a highly-available key value store used by Kubernetes deployments for persistent storage of all of its REST API objects. These objects are sensitive in nature and should not be available to unauthenticated clients. You should enable the client authentication via valid certificates to secure the access to the etcd service.

How to Fix
