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 | Frequent DNS resolution of same domain with rotating IPs | 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 |
|---|---|
ResolverConfigPaths | Whitelist of expected DNS resolvers configured on ESXi |
ExternalDomainWhitelist | Known trusted external domains for hypervisor services |
