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 | network, socket, and http logs | DC0085 Network Traffic Content |
| macos:osquery | process_events | 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 |
|---|---|
UnsignedBinary | Helps tune detection when unsigned apps initiate fronted sessions. |
HostHeaderMatch | Threshold to flag inconsistent domain targeting in encrypted sessions. |
SOCKSPortAnomaly | Alert on unusual ports used in HTTPS+SOCKS activity patterns. |
