The following example records an IAM principal creating an encrypted volume using the default volume key in the Amazon EC2 management console.
The following example shows a CloudTrail log entry in which user Alice creates an encrypted volume
with a default volume key in the Amazon EC2 management console. The EC2 log file record includes a
volumeId field with a value of "vol-13439757". The AWS KMS record
contains an encryptionContext field with a value of "aws:ebs:id":
"vol-13439757". Similarly, the principalId and accountId
between the two records match. The records reflect the fact that creating an encrypted volume
generates a data key that is used to encrypt the volume content.
