# Macie 调查结果的亚马逊 EventBridge 事件架构
为了支持与其他应用程序、服务和系统（例如监控或事件管理系统）的集成，Amazon Macie 会自动将调查结果 EventBridge 作为事件发布给亚马逊。 EventBridge，前身为 Amazon CloudWatch Events，是一种无服务器事件总线服务，可将来自应用程序和其他应用程序的实时数据流传输 AWS 服务 到目标，例如 AWS Lambda 函数、亚马逊简单通知服务主题和 Amazon Kinesis 流。要了解更多信息 EventBridge，请参阅 [Amazon EventBridge 用户指南](https://docs.aws.amazon.com/eventbridge/latest/userguide/eb-what-is.html)。
**注意**
如果您当前使用 CloudWatch 事件，请注意 EventBridge 和 CloudWatch 事件是相同的底层服务和 API。但是， EventBridge 包括其他功能，使您能够接收来自软件即服务 (SaaS) 应用程序和您自己的应用程序的事件。由于基础服务和 API 相同，因此 Macie 发现的事件架构也相同。
Macie 会自动发布所有新调查发现和现有策略的后续调查发现的事件，但使用[抑制规则](findings-suppression.md)自动存档的调查发现除外。这些事件是符合 AWS 事件 EventBridge 架构的 JSON 对象。每个事件都包含特定调查发现的 JSON 表示。由于数据结构化为 EventBridge 事件，因此您可以使用其他应用程序、服务和工具更轻松地监控、处理发现并根据发现采取行动。要详细了解 Macie 如何以及何时发布有关调查发现的事件，请参阅 [为调查发现配置发布设置](findings-publish-frequency.md)。

## Macie 调查发现的事件架构
以下示例显示了亚马逊 Macie [ EventBridge 搜索结果的亚马逊事件](https://docs.aws.amazon.com/eventbridge/latest/userguide/eb-events.html)架构。有关调查发现事件中包含字段的详细描述，请参阅 *Amazon Macie API 引用*中的[调查发现](https://docs.aws.amazon.com/macie/latest/APIReference/findings-describe.html)。调查发现事件的结构和字段与 Amazon Macie API 的 `Finding` 对象非常接近。

## 策略调查发现事件示例
以下示例使用示例数据演示[策略调查结果](findings-types.md#findings-policy-types)的 Amazon EventBridge 事件中对象和字段的结构和性质。在此示例中，该事件报告了后续出现的现有策略调查发现：Amazon Macie 检测到禁用阻止 S3 存储桶公开访问设置。以下字段和值可帮助您确定情况是否如此：
+ 该 `type` 字段设置为 `Policy:IAMUser/S3BlockPublicAccessDisabled`。
+ `createdAt` 和 `updatedAt` 字段的值不同。此指标表明，该事件报告了现有策略调查发现的后续发生。如果事件报告了新调查发现，则这些字段的值将相同。
+ `count` 字段设置为 `2`，表示这是调查发现的第二次出现。
+ 该 `category` 字段设置为 `POLICY`。
+ `classificationDetails` 字段值为 `null`，这有助于将此策略调查发现事件与敏感数据调查发现事件区分开来。对于敏感数据调查发现，此值将是一组对象和字段，这些对象和字段提供有关敏感数据的查找方式及数据内容。
请注意，`sample` 字段值设置为 `true`。此值强调这是文档中所使用的示例事件。

## 敏感数据调查发现事件示例
以下示例使用示例数据来演示[敏感数据发现](findings-types.md#findings-sensitive-data-types)的 Amazon EventBridge 事件中对象和字段的结构和性质。在此示例中，该事件报告了一项新调查发现的敏感数据：Amazon Macie 在 S3 对象中发现了多个类别和类型的敏感数据。以下字段和值可帮助您确定情况是否如此：
+ 该 `type` 字段设置为 `SensitiveData:S3Object/Multiple`。
+ `createdAt` 和 `updatedAt` 字段值相同。与策略调查发现不同的是，敏感数据调查发现总是如此。所有敏感数据调查发现均被视为新调查发现。
+ `count` 字段设置为 `1`，表示这是一项新调查发现。与策略调查发现不同的是，敏感数据调查发现总是如此。所有敏感数据调查发现都被认为具有唯一性（新）。
+ 该 `category` 字段设置为 `CLASSIFICATION`。
+ `policyDetails` 字段值为 `null`，这有助于将敏感数据调查发现事件与策略调查发现事件区分开来。对于策略调查发现，此值将是一组对象和字段，这些对象和字段提供有关 S3 存储桶可能违反策略、安全性或隐私问题的信息。
请注意，`sample` 字段值设置为 `true`。此值强调这是文档中所使用的示例事件。
