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:shell | Execution of cat, tail, grep targeting /var/log/vmkernel.log or /var/log/hostd.log | DC0064 Command Execution |
| esxi:hostd | read: Access to sensitive log files by non-admin users | DC0055 File Access |
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 |
|---|---|
AdminSessions | Correlate with legitimate administrator access sessions to reduce noise. |
