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 stack resource exhaustion, tcp_accept queue overflow, repeated resets | DC0018 Host Status |
| macos:osquery | Execution of flooding tools or compiled packet generators | DC0032 Process Creation |
| NSM:Firewall | Anomalous TCP SYN or ACK spikes from specific source or interface | 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 |
|---|---|
SystemLoadThreshold | Observed CPU/network degradation level that triggers response |
ToolExecutionPath | Where DoS tools are commonly dropped or compiled |
