ソフトウェアのセキュリティは、セキュリティ ソフトウェアではありません。ここでは、認証、アクセス制御、機密性、暗号化、権限管理などのトピックについて説明します。
Kubernetes Misconfiguration: readOnlyPort Enabled
Abstract
オープンアクセスの Kubelet API はシステム情報を漏洩します。
Explanation
下位互換性を維持するため、Kubelet は、認証や承認を必要とせずに、読み取り専用ポートで API のサブセットに対応できます。これらの API の戻り値には、Kubelet が提供するノードの非常に詳細な仕様とパフォーマンス メトリック、およびそのノードにデプロイされたポッドのメタデータが含まれます。
例 1: 次の設定では、Kubelet の読み取り専用ポートが
例 1: 次の設定では、Kubelet の読み取り専用ポートが
12345 に設定されます。
...
kind: KubeletConfiguration
...
readOnlyPort: 12345
