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 | log stream (subsystem: com.apple.system.networking) | DC0085 Network Traffic Content |
| macos:osquery | process_events | DC0032 Process Creation |
| macos:osquery | file_events | DC0039 File 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 |
|---|---|
ProtocolUnusualnessScore | Weight rarely-used protocols in user space. |
ExecutableBaselining | Track which binaries usually call curl/nc and alert on deviation. |
