AWS WAF の情報 AWS CloudTrail
すべての AWS WAF アクションは によってログに記録 AWS CloudTrail され、 AWS WAF API リファレンス に記載されています。例えば、、ListWebACL、 を呼び出すとUpdateWebACL、 CloudTrail ログファイルにエントリDeleteWebACLが生成されます。
各イベントまたはログエントリには、誰がリクエストを生成したかという情報が含まれます。アイデンティティ情報は、以下を判別するのに役立ちます:
-
リクエストが、ルートユーザーの認証情報で行われたかどうか
-
リクエストが、ロールとフェデレーティッドユーザーのどちらの一時的なセキュリティ認証情報を使用して送信されたか
-
リクエストが別の AWS サービスによって行われたかどうか
詳細については、CloudTrailuserIdentity Element」を参照してください。
例: AWS WAF ログファイルエントリ
証跡は、指定した Amazon S3 バケットにイベントをログファイルとして配信できるようにする設定です。 AWS CloudTrail ログファイルには 1 つ以上のログエントリが含まれます。イベントは任意ソースからの単一リクエストを表し、リクエストされたアクション、アクションの日時、リクエストパラメータなどの情報を含みます。 CloudTrail ログファイルはパブリック API コールの順序付けられたスタックトレースではないため、特定の順序では表示されません。
AWS WAF ウェブ ACL オペレーションの CloudTrail ログエントリの例を次に示します。
