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 | esxcli network firewall set commands | DC0064 Command Execution |
| esxi:hostd | vSphere API calls modifying firewall settings | DC0051 Firewall Rule Modification |
Mutable elements

| Field | Description |

APIMethods | Whitelist of authorized vSphere API methods for firewall configuration. |
