Microsoft Defender for Identity SIEM 日志参考

项目
09/24/2024

Defender for Identity 可以将安全警报和运行状况警报事件转发到 SIEM。警报和事件采用 CEF 格式。本参考文章提供了发送到 SIEM 的日志示例。

注意

建议使用流式处理 API 或 REST API 将 SIEM 工具与 Microsoft Defender XDR 集成。此方法使你能够转发来自所有 Defender XDR 产品的所有事件和警报，而不仅仅是 Defender for Identity 事件和警报。

CEF 格式的 Defender for Identity 安全警报示例

以下字段及其值将转发到 SIEM：

详细信息	说明
start	警报启动时间
suser	警报中涉及的帐户（通常为用户帐户）
shost	警报中涉及的帐户（通常为计算机帐户）
结果	警报中可疑活动成功或失败（如果相关）
msg	警报的描述
cnt	对于包含活动发生次数计数的警报（例如，暴力包含猜测的密码数）
应用程序	此警报中使用的协议
externalId	Defender for Identity 写入与每种警报对应的事件日志的事件 ID。
cs#label	CEF 允许的客户字符串，其中 cs#label 是新字段的名称
cs#	CEF 允许的客户字符串，其中 cs# 是值。

例如：cs1Label=url cs1=https\://security.microsoft.com/alerts/aa5909ae198ca1ec04d05e65fa
cs1 字段是警报 URL。
例如：cs2Label=trigger cs2=new
cs2 字段用于识别警报是新警报还是更新后的警报。
例如：cs3Label=shostfqdn cs3=client1.contoso.com cs3 字段用于标识源计算机名称的完全限定域名。

注意

如果计划为 Defender for Identity SIEM 日志创建自动化或脚本，建议使用 externalId 字段来标识警报类型，而不是使用警报名称实现此目的。警报名称有时可能会修改，而每个警报的 externalId 是永久性的。有关外部 ID 的列表，请参阅安全警报名称映射和唯一外部 ID。

示例日志

日志示例符合 RFC 5424 要求，但 Defender for Identity 同时支持 RFC 3164。

注意

下面的列表是发送到 SIEM 的日志示例。有关警报详细信息的完整列表，请参阅安全警报名称映射和唯一外部 ID。

优先级：

3 = 低
5 = 中等
10 = 高
