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 |
|---|---|---|
| networkdevice:syslog | SIP REGISTER, INVITE, or unusual call destination metadata | DC0038 Application Log 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 |
|---|---|
CallDestinationPatterns | Regular expressions or rules for spotting abnormal call destinations |
UserContext | Expected users who initiate VoIP traffic vs. anomalous accounts |
