# S3 on Outposts 和 Amazon S3 的 CloudTrail 日誌檔案項目
<a name="cloudtrail-logging-understanding-s3-entries"></a>

**重要**  
Amazon S3 現在將伺服器端加密與 Amazon S3 受管金鑰 (SSE-S3) 套用為 Amazon S3 中每個儲存貯體的基本加密層級。從 2023 年 1 月 5 日起，所有上傳到 Amazon S3 的新物件都會自動加密，無需額外費用，也不會影響效能。S3 儲存貯體預設加密組態和新物件上傳的自動加密狀態可在 CloudTrail 日誌、S3 庫存、S3 Storage Lens、Amazon S3 主控台，以及 AWS CLI 和 AWS SDKs 中的其他 Amazon S3 API 回應標頭中使用。如需詳細資訊，請參閱[預設加密常見問答集](https://docs.aws.amazon.com/AmazonS3/latest/userguide/default-encryption-faq.html)。

一個事件代表任何來源提出的單一請求，並包含請求 API 操作的相關資訊、操作的日期和時間、請求參數等。CloudTrail 日誌檔案不是公有 API 呼叫的已排序堆疊追蹤，因此事件不會以任何特定順序顯示。

**注意**  
若要檢視 Amazon S3 Express One Zone 的 CloudTrail 日誌檔案範例，請參閱 [S3 Express One Zone 的 CloudTrail 日誌檔案範例](https://docs.aws.amazon.com/AmazonS3/latest/userguide/s3-express-log-files.html)。

如需詳細資訊，請參閱下列範例。
