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 | method=RemoveUser or esxcli system account remove invocation | DC0009 User Account Deletion |
| esxi:vpxa | user login from unexpected IP or non-admin user role | DC0002 User Account Authentication |
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 |
|---|---|
RemoteUserRole | ESXi role triggering the change (e.g., Administrator vs. Viewer) |
ExpectedIPs | IP ranges authorized to conduct admin-level actions |
