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 | Non-standard Office startup component detected (e.g., unexpected DLL path) | DC0016 Module Load |
| m365:office | Startup execution includes non-default component | 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 |
|---|---|
TrustedLocationBypass | DLL may be placed in location trusted by Office configuration or signed to evade alerts |
AuditPolicyScope | Only specific tenants or users may have Office auditing enabled at granular DLL load level |
