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 connection events | DC0082 Network Connection Creation |
| NSM:Flow | Inbound HTTP POST with suspicious payload size or user-agent | DC0085 Network Traffic Content |
| macos:unifiedlog | exec logs | 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 |
|---|---|
UserAgentFingerprint | Flag browser-based sessions |
HeaderSignatureMatch | Specific HTTP header anomalies or patterns (e.g., spoofed User-Agent). |
