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:vmkernel | egress log analysis | DC0078 Network Traffic Flow |
| esxi:hostd | execution + payload hints | DC0064 Command Execution |
| NSM:Flow | host switch egress data | 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 |
|---|---|
GuestVMExfilWatchlist | VMs with data sensitivity labels or outside normal behavior. |
ServiceEgressProfile | Expected egress destinations and volume for core services. |
