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 | Set-Mailbox, Add-InboxRule, RegisterWebhook | DC0038 Application Log Content |
| saas:api | Webhook registrations or repeated POST activity | DC0078 Network Traffic Flow |
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 |
|---|---|
WebhookRegistrations | Monitor new webhook creation events in SaaS environments. |
ExternalDomains | Flag webhooks pointing to domains not owned by the enterprise. |
