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=3, 22 | DC0082 Network Connection Creation |
| etw:Microsoft-Windows-WinINet | WinINet API telemetry | 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 |
|---|---|
DestinationDomain | Can tune for popular web services (e.g., googleapis.com, github.com) based on threat actor tooling |
TimeWindow | May adjust temporal window to catch beaconing patterns (e.g., every 10-30 mins) |
ProcessName | Environment-specific tuning to exclude expected update or telemetry tools |
