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 |
|---|---|---|
| networkdevice:IDS | content inspection / PCAP / HTTP 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 |
|---|---|
EntropyThreshold | Adjust threshold to reduce false positives in compressed but benign data |
ProtocolScope | Refine by enabling inspection of specific exfil vectors (e.g., FTP, HTTP POST) |
