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 |
|---|---|---|
| m365:unified | FileAccessed: Access of email attachments by Office applications | DC0038 Application Log Content |
| WinEventLog:Sysmon | EventCode=1 | DC0032 Process Creation |
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 |
|---|---|
ParentProcessList | Parent processes expected to execute child processes (e.g., Office apps). |
MacroExecutionThreshold | Threshold for number of macros executed before raising alerts. |
