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 |
|---|---|---|
| WinEventLog:Security | EventCode=4624, 4648 | DC0067 Logon Session Creation |
| m365:unified | SendOnBehalf/SendAs: Emails sent where the sending identity mismatches account ownership | 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 |
|---|---|
KeywordList | Adjust impersonation detection keywords based on local business risk terms (e.g., 'ACH', 'Invoice'). |
GeoLocationBaseline | Define trusted geographic regions for normal user email activity. |
