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:Sysmon | EventCode=1 | DC0032 Process Creation |
| WinEventLog:Sysmon | EventCode=11 | DC0039 File Creation |
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 |
|---|---|
mutex_name_entropy_threshold | Filter out common benign mutex names; highlight suspicious high-entropy/dynamic names. |
parent_process_path | Limit alerting to non-standard parent-child relationships indicative of malware staging or self-spawning. |
TimeWindow | Correlate mutex creation + rapid process exit or lack of further activity within a short timeframe. |
