Contoh dua Amazon EC2

Dalam contoh berikut, prinsipal IAM yang menjalankan instans Amazon EC2 membuat dan memasang volume data yang dienkripsi di bawah kunci KMS. Tindakan ini menghasilkan beberapa catatan CloudTrail log.

Ketika volume dibuat, Amazon EC2, yang bertindak atas nama pelanggan, mendapatkan kunci data terenkripsi dari AWS KMS (GenerateDataKeyWithoutPlaintext). Kemudian, volume membuat izin (CreateGrant) yang memungkinkannya untuk mendekripsi kunci data. Ketika volume terpasang, Amazon EC2 memanggil AWS KMS untuk mendekripsi kunci data (Decrypt).

instanceId dari instans Amazon EC2, "i-81e2f56c", akan muncul dalam peristiwa RunInstances. ID instans yang sama memenuhi syarat granteePrincipal dari izin yang dibuat ("111122223333:aws:ec2-infrastructure:i-81e2f56c") dan asumsi peran yang merupakan perwakilan dalam panggilan Decrypt ("arn:aws:sts::111122223333:assumed-role/aws:ec2-infrastructure/i-81e2f56c").

Kunci ARN dari kunci KMS yang melindungi volume data,arn:aws:kms:us-west-2:111122223333:key/1234abcd-12ab-34cd-56ef-1234567890ab, muncul di ketiga AWS KMS panggilan (CreateGrant,GenerateDataKeyWithoutPlaintext, dan). Decrypt
