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:osquery | socket_events | DC0078 Network Traffic Flow |
| macos:unifiedlog | log stream --predicate | DC0064 Command Execution |
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 |
|---|---|
FilePathAccessed | e.g., ~/Documents, ~/Library/logs/ |
NetworkPortAnomaly | Non-standard FTP/TFTP ports used (e.g., FTP over 443) |
