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 |
| Windows:perfmon | Sudden spike in outbound throughput without corresponding inbound traffic | DC0018 Host Status |
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 | Interval for measuring sudden outbound spike or volume pattern |
AmplificationProtocolPorts | List of known ports used for reflection amplification (e.g., 53/DNS, 123/NTP, 11211/Memcached) |
PacketToByteRatio | Heuristic threshold where the response volume far outweighs the request volume |
