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 | FileAccessed, MailboxAccessed | DC0055 File Access |
| m365:unified | UserLoggedIn | DC0067 Logon Session Creation |
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 |
|---|---|
DevicePlatformMismatch | Raise alerts on login from CLI when user typically uses web-only |
SensitiveDocumentAccessPattern | Track access to documents labeled as internal/confidential |
AccessFrequencyThreshold | Tune for high-volume document reads post login |
