Amazon EC2 示例一

以下示例记录了 IAM 委托人使用亚马逊 EC2 管理控制台中的默认卷密钥创建加密卷。

以下示例显示了一个 CloudTrail 日志条目，在该日志条目中，用户 Alice 在 Amazon EC2 管理控制台中使用默认卷密钥创建了一个加密卷。 EC2 日志文件记录包括一个值为的volumeId字段"vol-13439757"。该 Amazon KMS 记录包含一个值为的encryptionContext字段"aws:ebs:id": "vol-13439757"。同样，这两个记录的 principalId 和 accountId 都相互匹配。这些记录反映了一个事实，即创建加密卷生成的数据密钥被用于加密卷内容。
