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 | unset HISTFILE or HISTFILESIZE modifications | DC0064 Command Execution |
Mutable elements
