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 |
|---|---|---|
| macos:unifiedlog | DNS responses followed by connections to ports outside standard ranges | DC0085 Network Traffic Content |
| macos:unifiedlog | Unexpected processes making network calls based on DNS-derived ports | DC0032 Process 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 |
|---|---|
ProcessAllowlist | Expected processes allowed to open non-standard ports (e.g., developer tools) |
ConnectionVolumeThreshold | Volume of unusual connections needed before flagging as suspicious |
