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 | TokenIssued, FileAccessed | DC0007 Web Credential Usage |

| Field | Description |
|---|---|
UserAgentCheck | Tune to detect access from CLI agents or scripts rather than interactive browsers |
