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 | pfctl -d, socketfilterfw --setglobalstate off, or modifications to com.apple.alf | DC0064 Command Execution |

| Field | Description |

PFConfigFiles | Monitor for baseline pf.conf and custom rule file modifications. |
