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 | Storage access and file ops | DC0059 File Metadata |
| esxi:hostd | Service initiated connections | DC0082 Network Connection Creation |
| NSM:Flow | Transferred file observations | 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 |
|---|---|
FilenamePattern | Tune for likely stego file names (e.g., wallpaper.jpg, template.iso). |
UnusualDestinationIP | Destination outside vCenter management subnet. |
