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 |
|---|---|---|
| azure:signinlogs | InteractiveUser, ServicePrincipalSignIn | DC0067 Logon Session Creation |
| azure:audit | Add delegated admin / Assign admin roles / Update application consent | DC0088 Logon Session Metadata |

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 |
|---|---|
TrustedPartnerTenantIDs | Tenant IDs of approved partners; any others are suspicious. |
RequiredMFA | Require MFA for partner sessions; alert on bypass or step-up failure. |
RoleScopeAllowList | Roles third-parties may hold (e.g., Helpdesk Admin); flag broader scopes. |
