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 | event stream | DC0064 Command Execution |
| NSM:Flow | flow records | DC0078 Network Traffic Flow |
| NSM:Flow | http.log | 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 |
|---|---|
VMConfigAccessPathWatchlist | Locations of VMX/CFG/SNAPSHOT files that should not be accessed by non-admin shells. |
OutboundProtocolProfile | Expected network protocols for guest and host interfaces. |
