Nell'esempio seguente, un principale IAM che esegue un' EC2 istanza Amazon crea e monta un volume di dati crittografato con una chiave KMS. Questa azione genera più record di CloudTrail log.
Quando il volume viene creato, Amazon EC2, agendo per conto del cliente, ottiene una chiave dati crittografata da AWS KMS (GenerateDataKeyWithoutPlaintext). Quindi crea un’autorizzazione (CreateGrant) che gli consente di decrittografare la chiave dati. Quando il volume è montato, Amazon EC2 chiama AWS KMS per decrittografare la chiave dati ()Decrypt.
L'instanceId EC2 istanza Amazon,"i-81e2f56c", appare nell'RunInstancesevento. Lo stesso ID dell’istanza qualifica l’elemento granteePrincipal dell’autorizzazione creato ("111122223333:aws:ec2-infrastructure:i-81e2f56c") e il ruolo assunto che è l'entità nella chiamata Decrypt ("arn:aws:sts::111122223333:assumed-role/aws:ec2-infrastructure/i-81e2f56c").
L'ARN della chiave KMS che protegge il volume di dati appare in tutte e tre le AWS KMS chiamate (CreateGrantGenerateDataKeyWithoutPlaintext, e). arn:aws:kms:us-west-2:111122223333:key/1234abcd-12ab-34cd-56ef-1234567890ab Decrypt
