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=4776, 4625 | DC0002 User Account Authentication |
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 | Adjustable window to correlate failed logons, e.g., 5-10 minutes |
UserContext | Define scope of monitored users (e.g., service accounts, admins) |
FailureThreshold | Count of failed logons before raising an alert (e.g., 10-15) |
