Dans l'exemple suivant, un directeur IAM exécutant une EC2 instance Amazon crée et monte un volume de données chiffré sous une clé KMS. Cette action génère plusieurs enregistrements de CloudTrail journal.
Lorsque le volume est créé, Amazon EC2, agissant pour le compte du client, obtient une clé de données cryptée auprès de AWS KMS (GenerateDataKeyWithoutPlaintext). Ensuite, il crée un octroi (CreateGrant) qui lui permet de déchiffrer la clé de données. Lorsque le volume est monté, Amazon EC2 appelle AWS KMS pour déchiffrer la clé de données (Decrypt).
Le instanceId de l' EC2 instance Amazon apparaît dans l'RunInstancesévénement. "i-81e2f56c" Le même ID d'instance qualifie le granteePrincipal de l'octroi créé ("111122223333:aws:ec2-infrastructure:i-81e2f56c") et le rôle supposé qui est le principal dans l'appel Decrypt ("arn:aws:sts::111122223333:assumed-role/aws:ec2-infrastructure/i-81e2f56c").
La clé ARN de la clé KMS qui protège le volume de données apparaît dans les trois AWS KMS appels (CreateGrantGenerateDataKeyWithoutPlaintext, etDecrypt). arn:aws:kms:us-west-2:111122223333:key/1234abcd-12ab-34cd-56ef-1234567890ab
