项目
01/15/2025

通过将 Microsoft Defender for Cloud 的数据与 Microsoft Power BI 连接，你可以轻松监视和分析安全指标。通过集成，你可以可视化安全见解并快速识别潜在威胁和漏洞。本文指导你完成将 Defender for Cloud 数据连接到 Power BI 的步骤，帮助你将复杂的安全信息转换为清晰、可操作的见解。

先决条件

下载并安装 Power BI Desktop。
确保你具有访问 Azure Resource Graph 的正确权限。

将 Power BI 连接到 Azure Resource Graph

必须先将 Power BI 连接到 Azure Resource Graph，然后才能将 Defender for Cloud 的数据连接到 Power BI。

在桌面上打开 Power BI Desktop。
选择空白报表。
选择获取数据>更多。
搜索并选择 Azure Resource Graph。
选择“连接” 。

在 Power BI 中查询 Defender for Cloud 数据

将 Power BI Desktop 连接到 Azure Resource Graph 后，你可以使用 Azure Resource Graph 在 Power BI 中查询 Defender for Cloud 的各种数据源。

本页提供的查询是提供结果的示例。 Azure Resource Graph 允许你查询各种数据，你可以创建和自定义这些数据以返回适合您特定要求的结果。

将提供的查询之一复制并粘贴到 Power BI Desktop 内的查询编辑器中。

此查询从 MDC 按风险检索安全建议，让你能够分析评估并确定需要关注的领域。

| summarize count() by assignmentStatus

此查询从 MDC 检索符合性数据，这对于维护和证明遵守各种法规要求至关重要。

securityresources
| where type == "microsoft.security/regulatorycompliancestandards/regulatorycompliancecontrols/regulatorycomplianceassessments" | extend scope = properties.scope
| where isempty(scope) or  scope in~("Subscription", "MultiCloudAggregation")
| parse id with * "regulatoryComplianceStandards/" complianceStandardId "/regulatoryComplianceControls/" complianceControlId "/regulatoryComplianceAssessments" *

选择“确定”。

注意

默认情况下，Resource Graph 限制任何查询都只能返回 1,000 条记录。这项控制措施可保护你和服务不受会生成大型数据集的意外查询影响。如果你希望查询结果不会因 1000 条记录的限制而被截断，请将“高级选项 - $resultTruncated (可选)”的值设置为 FALSE。
选择“加载”。

借助 Azure Resource Graph，你可以灵活地检索和分析 Defender for Cloud 环境中提供的任何数据，确保获得全面的定制见解。将数据添加到 Power BI 后，你可以创建可视化效果和仪表板，以有效地监视和管理安全状况。
