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 | datastore file access | DC0055 File Access |
| esxi:vmkernel | HTTPS POST connections to webhook endpoints | 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 |
|---|---|
DatastoreExfilThreshold | Minimum data volume to flag exfiltration attempts from VM files. |
ApprovedIntegrations | Whitelisted CI/CD or automation webhooks tied to vSphere/ESXi. |
