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:syslog | boot logs | DC0064 Command Execution |
| esxi:shell | admin command usage | DC0061 File Modification |
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 |
|---|---|
script_section | Tunable script section edited by adversary (beginning, end, inline) |
command_type | Nature of embedded command or payload affects detection scope |
execution_trigger | Boot vs. manual script re-invocation |
