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=4688 | DC0032 Process Creation |
| WinEventLog:Sysmon | EventCode=11 | DC0039 File Creation |
| NSM:Flow | Unexpected script or binary content returned in HTTP response body | DC0085 Network Traffic Content |
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 |
|---|---|
MonitoredExtensions | File extensions to flag (exe, dll, js, vbs, sh, etc.). |
SuspiciousParentProcesses | Browser processes (chrome.exe, firefox.exe, edge.exe, etc.) monitored as possible parents for malicious activity. |
RedirectList | List of suspicious domains or URLs used for malicious redirects. |
