列表 detectionRules
命名空间：microsoft.graph.security
重要
Microsoft Graph /beta 版本下的 API 可能会发生更改。 不支持在生产应用程序中使用这些 API。 若要确定 API 是否在 v1.0 中可用，请使用 版本 选择器。
获取 自定义检测规则的列表。 借助自定义检测，可以主动监视和响应各种事件和系统状态，包括可疑的泄露活动和组织网络中配置错误的资产。 自定义检测规则是用 Kusto 查询语言 (KQL) 编写的，一旦发生与其 KQL 查询匹配的事件，就会自动触发 警报 和响应操作。
此 API 可用于以下国家级云部署。
| 全局服务 | 美国政府 L4 | 美国政府 L5 (DOD) | 由世纪互联运营的中国 |
|---|---|---|---|
| ✅ | ❌ | ❌ | ❌ |
权限
为此 API 选择标记为最低特权的权限。 只有在应用需要它时，才使用更高的特权权限。 有关委派权限和应用程序权限的详细信息，请参阅权限类型。 要了解有关这些权限的详细信息，请参阅 权限参考。
