Security Command Center API を使用して知見を管理する

このガイドでは、Security Command Center API を使用した検出結果の作成、更新について説明します。

要件: 検出結果を作成するには、Security Command Center を組織レベルで有効にする必要があります。

始める前に

知見を作成および更新する前に、次の手順を行う必要があります。

• Security Command Center API で認証する
• 検出結果のソースがあること

このガイドを完了するには、組織レベルで Identity and Access Management（IAM）のSecurity Center 検出結果編集者（securitycenter.findingsEditor）ロールが必要です。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。

セキュリティ マークが付いた知見を作成するには、使用するマークの種類に対する権限を含む次の IAM ロールも必要です。

• Asset セキュリティ マーク ライター（securitycenter.assetSecurityMarksWriter）
• セキュリティ マーク ライターの検出（securitycenter.findingSecurityMarksWriter）

マークの詳細については、Security Command Center のセキュリティ マークの使用をご覧ください。

知見の作成

ソースに対してアクティブな検出結果を作成します。

注: Security Command Center がプロジェクト レベルで有効になっている場合、検出結果の作成はサポートされません。

検出結果のデータが Security Command Center に保存される期間については、検出結果の保持をご覧ください。

ソース プロパティを使用して知見を作成する

Security Command Center では、「ソース プロパティ」と呼ばれる Key-Value メタデータを使用して、コンテキストを知見に追加できます。ソース プロパティは作成時に初期化できます。以下の例は、ソース プロパティを使用して知見を作成する方法を示しています。

ソース プロパティを使用して知見を作成します。source_properties マップ内のキー名の長さは 1〜255 文字で、文字で始まり、英数字またはアンダースコアのみを含む必要があります。Security Command Center は、ブール値、数値、文字列の値のみをサポートしています。

検出結果の権限の確認

知見を作成または更新するには、次のいずれかの IAM 権限が必要です。

• 知見の作成と更新: securitycenter.findings.update。
• 知見の更新のみ: securitycenter.findings.setState。

ソースの検出結果を作成できない場合は、次のコードを使用して、始める前にのセクションに記載されている必要な権限がアカウントに付与されていることを確認してください。必要な権限が付与されていない場合は、セキュリティ ソースの作成と管理を参照して適切な IAM ポリシーを設定してください。
