您可以使用 AWS CloudTrail 日誌來監控 AWS Nitro enclave 的 Decrypt、DeriveSharedSecret、 GenerateDataKey、 GenerateDataKeyPair 和 GenerateRandom 操作。在這些日誌項目，additionalEventData 欄位具 recipient 欄位，其中包含請求證明文件的模組 ID (attestationDocumentModuleId)、影像摘要 (attestationDocumentEnclaveImageDigest)，以及平台組態註冊 (PCR)。只有在請求中的 Recipient 參數指定來自 AWS Nitro enclave 的已簽署證明文件時，才會包含這些欄位。
模組 ID 是 Nitro enclave 的 enclave ID。影像摘要是 enclave 影像的 SHA384 雜湊。您可在金鑰政策與 IAM 政策的條件運用影像摘要及 PCR 值。如需 PCR 的相關資訊，請參閱《AWS Nitro Enclaves使用者指南》的Where to get an enclave's measurements。
本節針對每個支援的 Nitro enclave AWS KMS請求顯示 CloudTrail 日誌項目範例。
