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=4625, 4771, 4648 | 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 |
|---|---|
PasswordReuseThreshold | Number of distinct accounts a password is used against before alerting |
TimeWindow | Window over which the correlation is measured (e.g., 10 mins) |
TargetGroupFilter | Limit detection to sensitive or monitored user groups (e.g., Admins) |
