NRT Modified domain federation trust settings
Description
'This will alert when a user or application modifies the federation settings on the domain or Update domain authentication from Managed to Federated.
For example, this alert will trigger when a new Active Directory Federated Service (ADFS) TrustedRealm object, such as a signing certificate, is added to the domain.
Modification to domain federation settings should be rare. Confirm the added or modified target domain/URL is legitimate administrator behavior.
To understand why an authorized user may update settings for a federated domain in Office 365, Azure, or Intune, see: https://docs.microsoft.com/office365/troubleshoot/active-directory/update-federated-domain-office-365.
For details on security realms that accept security tokens, see the ADFS Proxy Protocol (MS-ADFSPP) specification: https://docs.microsoft.com/openspecs/windows_protocols/ms-adfspp/e7b9ea73-1980-4318-96a6-da559486664b.
