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 |

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 |
|---|---|
OperationName | Identify rare trust-modification operations (SetDomainAuthentication, Update-MsolFederatedDomain). |
InitiatedBy | Flag federated trust changes performed by unknown users, service principals, or tokens. |
UserAgent | Separate scripted/API interactions from GUI-based administrative changes. |
TimeWindow | Correlate trust change to federated login or SAML token injection within short window. |
