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 | subsystem: com.apple.network | DC0085 Network Traffic Content |
| macos:osquery | process_events/socket_events | DC0082 Network Connection 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 |
|---|---|
TargetService | Known services abused for D2 (e.g., iCloud, Dropbox) |
UserContext | Useful to isolate rare users accessing web services for C2 |
TimeWindow | Max time gap between dead drop resolver fetch and follow-on traffic |
