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 |
| WinEventLog:Security | EventCode=4672 | DC0088 Logon Session Metadata |
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 | Tune for normal business hours to reduce false positives from legitimate after-hours work. |
UserContext | Define list of legitimate local users for interactive access. |
