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:hostd | Service-Based Network Connection | DC0082 Network Connection Creation |
| NSM:Content | TLS Fingerprint and Certificate Analysis | DC0085 Network Traffic 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 |
|---|---|
TLSFingerprintMatch | Allows matching against known-good or known-bad JA3/JA3S hashes. |
AllowedServicePorts | Tune for expected network ports per ESXi role. |
