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:auth | None | DC0088 Logon Session Metadata |
| esxi:shell | None | DC0064 Command Execution |
| esxi:vmkernel | port 22 access | DC0078 Network Traffic Flow |
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 |
|---|---|
AllowedUsers | Legitimate SSH users to this host |
TimeWindow | Correlate SSH login and unauthorized commands or shell access |
CommandList | Flag commands like esxcli, rm, chmod post-login |
