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 |
|---|---|---|
| ApplicationLog:CallRecords | Outbound or inbound calls to high-risk or blocklisted numbers | 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 |
|---|---|
PhoneNumberBlocklist | List of known malicious or suspicious phone numbers; must be tuned per environment |
TimeWindow | Threshold for correlating call events with subsequent suspicious system activity |
