GCP Terraform Misconfiguration: GKE Cluster HTTP Basic Authentication
Abstract
Terraform 構成は、GKE クラスターでの HTTP 基本認証を有効にします。
Explanation
クラスターの中央管理エンティティである Kubernetes API サーバーは、HTTP 基本認証を受け入れてユーザーを認証します。HTTP 基本認証は非推奨であり、ブルートフォース攻撃の影響を受けやすく、誤って設定された環境では攻撃者にユーザー資格情報を漏らす可能性があります。
例 1: 次の例は、
例 1: 次の例は、
master_auth
ブロックの username
と password
を空でない値に設定することにより、GKE クラスターで HTTP 基本認証を有効にする Terraform 構成を示しています。
resource "google_container_cluster" "container_cluster_demo" {
...
master_auth {
username = "foo"
password = "bar"
}
...
}
