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 execution of ssh with -L/-R forwarding flags | DC0032 Process Creation |
| macos:unifiedlog | encrypted outbound traffic carrying unexpected application data | 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 |
|---|---|
ExpectedDoHResolvers | Known legitimate DoH resolvers used in environment. |
PayloadEntropyThreshold | Flag excessive randomness in payloads on standard ports. |
