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 | Remove-InboxRule, Clear-Mailbox | DC0012 Scheduled Job Modification |
| m365:unified | PurgeAuditLogs, Remove-MailboxAuditLog | DC0038 Application Log Content |
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 |
|---|---|
TargetMailboxScope | Limit by VIP mailboxes or external-facing users |
AuditLogDepth | Tune for log deletion following lateral movement |
