使用亚马逊 EventBridge

Amazon EventBridge 是一项无服务器事件总线服务，可以轻松地将您的应用程序与来自各种来源的数据连接起来。 EventBridge 提供来自您自己的应用程序、S oftware-as-a-Service (SaaS) 应用程序和 Amazon 服务的实时数据流，并将这些数据路由到 Lambda 等目标。这使您能够监控服务中发生的事件，并构建事件驱动的架构。有关更多信息，请参阅 Amazon EventBridge 用户指南。

作为受 S3 恶意软件防护保护的 S3 存储桶的所有者账户，在以下情况下向默认事件总线 GuardDuty发布 EventBridge 通知：

  • 您的任何受@@ 保护存储桶的恶意软件防护计划资源状态会发生变化。有关各种状态的信息，请参见恶意软件防护计划资源状态。

  • 标签事件失败的原因如下：

    • 您 PassRole 的 IAM 缺少标记对象的权限。

      该添加 IAM 策略权限模板包括为对象 GuardDuty 添加标签的权限。

    • IAM 中指定的存储桶资源或对象已 PassRole 不存在。

    • 关联的 S3 对象已达到最大标签限制。有关标签限制的更多信息，请参阅 Amazon S3 用户指南中的使用标签对存储进行分类。

  • S 3 对象扫描结果将发布到您的默认 EventBridge 事件总线。

设置 EventBridge 规则

您可以在账户中设置 EventBridge 规则，将资源状态、扫描后标签失败事件或 S3 对象扫描结果发送给其他 Amazon Web Service人。作为委托 GuardDuty 管理员帐户，当恶意软件防护计划资源状态发生变化时，您将收到恶意软件防护计划资源状态通知。

将适用标准 EventBridge 定价。有关更多信息，请参阅 S3 恶意软件防护的定价。

在该示例中，所有以红色显示的值均为占位符。这些值将根据您的 S3 对象的扫描结果而变化。

您可以根据以下场景创建 EventBridge 事件模式：

潜在detail-type值

  • "GuardDuty Malware Protection Resource Status Active"

  • "GuardDuty Malware Protection Resource Status Warning"

  • "GuardDuty Malware Protection Resource Status Error"

事件模式

{
      "detail-type": ["potential detail-type"],

        }]
    }
}

该resourceStatus值可以是 Warning 或Error。

当受保护存储桶的 “状态” 列更改为 “警告” 或 “错误” 时，将根据根本原因填充该statusReasons值。有关故障排除步骤的信息，请参阅恶意软件防护计划故障排除状态详细信息。
