Log sources and channels
Exactly as MITRE states them in x_mitre_log_source_references. Where a channel is vague, it is vague in the source; kevmap does not tidy it.
| Log source | Channel | Data component |
|---|---|---|
| azure:signinlogs | Multiple MFA challenge requests without successful primary login | DC0002 User Account Authentication |
| NSM:Connections | PushNotificationSent | DC0038 Application Log Content |
Mutable elements
Parameters MITRE marks as environment-specific. These are the knobs you are expected to tune; they are why an analytic is not a rule.
| Field | Description |
|---|---|
TimeWindow | Threshold of MFA prompts per user within a short time period |
GeoIPAllowList | Expected login locations for workforce; deviations can be tuned |
