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 | process logs | DC0032 Process Creation |
| NSM:Flow | pf firewall logs | DC0078 Network Traffic Flow |
| macos:osquery | launchd or network_events | DC0082 Network Connection 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 |
|---|---|
LaunchAgentPath | Detect persistence used to restart proxy after reboot. |
ExternalPort | Often high or non-standard ports, configurable for outbound proxy detection. |
ProcessReputation | Flag unsigned or anomalous binaries making external connections. |
