重要
Amazon S3 现在将具有 Amazon S3 托管密钥的服务器端加密（SSE-S3）作为 Amazon S3 中每个存储桶的基本加密级别。从 2023 年 1 月 5 日起，上传到 Amazon S3 的所有新对象都将自动加密，不会产生额外费用，也不会影响性能。S3 存储桶默认加密配置和上传的新对象的自动加密状态可在 AWS CloudTrail 日志、S3 清单、S3 Storage Lens 存储统计管理工具、Amazon S3 控制台中获得，并可用作 AWS Command Line Interface 和 AWS SDK 中的附加 Amazon S3 API 响应标头。有关更多信息，请参阅默认加密常见问题解答。
一个事件表示一个来自任何源的请求，包括有关所请求的 API 操作、操作的日期和时间、请求参数等方面的信息。CloudTrail 日志文件不是公用 API 调用的有序堆栈跟踪，因此事件不会按任何特定顺序显示。
注意
