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 | Get-MsolServicePrincipal, ListAppRoles: Service discovery operations executed by accounts not normally performing administrative tasks | DC0083 Cloud Service Enumeration |
| m365:signinlogs | UserLogin: Discovery operations shortly after account logins from new geolocations | 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 |
|---|---|
MonitoredAppIntegrations | Specific Office Suite applications or plugins that may be enumerated or targeted. |
GeoLocationDeviation | Geographic deviation threshold for discovery actions linked to recent logins. |
