监控您的 Amazon Bedrock 服务的加密密钥

当您将 AWS KMS 客户托管密钥与您的 Amazon Bedrock 资源一起使用时，您可以使用AWS CloudTrail或 Amazon CloudWatch Logs 来跟踪 Amaz on Bedrock 向其发送的请求。 AWS KMS

以下是 Amazon Bedrock CreateGrant为创建主拨款而调用的监控 AWS KMS 操作的示例 AWS CloudTrail 事件：

按照创建策略中的步骤，将以下基于资源的策略附加到KMS密钥。该策略包含两个声明。

  1. 角色对模型自定义构件进行加密的权限。将导入ARNs的自定义模型构建器角色添加到该Principal字段。

  2. 角色在推理中使用导入的自定义模型的权限。将导入ARNs的自定义模型用户角色添加到该Principal字段。
