Description

This check verifies if the Kubernetes Dashboard add-on is enabled in the cluster configuration by examining the addon_profile block and specifically whether kube_dashboard { enabled = true } has been set. Enabling the Kubernetes Dashboard can expose sensitive cluster information and administrative controls via a web interface, increasing the risk of unauthorized access if not properly secured or restricted. For better security, the dashboard should be disabled by setting enabled = false:

addon_profile {
  kube_dashboard {
    enabled = false
  }
}

This reduces the potential attack surface and protects against possible privilege escalation or data exposure vulnerabilities.
