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 | MailItemsAccessed; AddedInboxRule; ConsentToApplication; SharingSet | DC0038 Application Log Content |
| m365:exchange | External sender message followed by user action involving links or attachments | DC0038 Application Log Content |
| m365:teams | External chat request or new tenant communication preceding approval activity | 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 |
|---|---|
ActionAfterMessageWindow | Time window between inbound communication and sensitive action |
TrustedDomainAllowlist | Known legitimate vendors or partner domains |
ApprovalAmountThreshold | Monetary threshold for finance workflows |
