监控 Nitro Enclave 的请求

您可以使用 AWS CloudTrail 日志来监控 AWS Nitro 飞地的解密DeriveSharedSecretGenerateDataKeyGenerateDataKeyPair、、、和GenerateRandom操作。在这些日志条目中，该additionalEventDatarecipient字段包含请求中认证文档中的模块 ID (attestationDocumentModuleIdattestationDocumentEnclaveImageDigest)、图像摘要 (PCRs) 和平台配置寄存器 ()。只有当请求中的Recipient参数指定来自 AWS Nitro 飞地的签名认证文档时，才会包含这些字段。

模块 ID 是 Nitro Enclave 的 Enclave ID。图像摘要是安全区图像的 SHA384 哈希值。您可以在密钥政策和 IAM policy 的条件中使用映像摘要和 PCR 值。有关信息 PCRs，请参阅《AWS Nitro Enclaves 用户指南》中的从何处获取飞地的测量值。

本节显示了每个受支持的 Nitro 安全区请求的 CloudTrail 日志条目示例。 AWS KMS
