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:osquery | process_events | DC0032 Process Creation |
| macos:unifiedlog | log stream - file provider subsystem | DC0055 File Access |
| NSM:Flow | ssl.log, x509.log | 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 |
|---|---|
OutboundTrafficVolumeThreshold | Trigger detection for large amounts of outbound encrypted data. |
FileSensitivityContext | Tagging and prioritizing high-value directories/files in detection logic. |
