Microsoft Defender for Identity

Microsoft Defender for Identity helps Active Directory admins defend against advanced persistent threats (APTs) targeting their Active Directory Domain Services infrastructures.

It is a cloud-based service, where agents on Domain Controllers provide signals to Microsoft's Machine Learning (ML) algorithms to detect and report on attacks. Its dashboard allows Active Directory admins to investigate (potential) breaches related to advanced threats, compromised identities and malicious insider actions.

Microsoft Defender for Identity was formerly known as Azure Advanced Threat Protection (Azure ATP) and Advanced Threat Analytics (ATA).

This detection relies on Windows event 4662, so it must be configured beforehand.
