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:exchange | Admin Audit Logs, Transport Rules | DC0038 Application Log Content |
| WinEventLog:PowerShell | Exchange Cmdlets | DC0064 Command Execution |
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 |
|---|---|
CmdletFilter | Include `New-TransportRule`, `Set-TransportRule`, `Remove-*` actions |
UserRoleScope | Track role assignments for admins performing deletions |
