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=3, 22 | DC0082 Network Connection 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 |
|---|---|
ScanRateThreshold | Defines the number of unique destination IPs or ports accessed within a time window that may indicate a scan. |
KnownScannerExeList | List of binaries allowed to scan or used by IT (e.g., Nmap, Nessus). |
TimeWindow | Temporal bounds for correlating sequential connections (e.g., 60 seconds). |
