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 |
|---|---|---|
| esxi:syslog | DNS resolution events leading to outbound traffic on unexpected ports | DC0078 Network Traffic Flow |
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 |
|---|---|
ManagementPlaneIPs | Known trusted ESXi management plane IPs to exclude from alerts |
DomainReputationFeed | Integrate external feeds for reputation context on DNS-derived domains |
