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 | logline inspection | DC0064 Command Execution |
| esxi:vmkernel | protocol egress | DC0082 Network Connection Creation |
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 |
|---|---|
GuestTrafficBaseline | Expected protocols used by VMs attached to host interfaces. |
ServiceAccountProfile | Unexpected network activity from hypervisor processes or monitoring agents. |
