Updated 08/10/2024—Microsoft Defender for Identity expands coverage with 10 new Active Directory security posture recommendations. These recommendations, part of Microsoft Secure Score, are new security posture reports related to Active Directory infrastructure and Group policy Objects (GPO).Updated 20/09/2024 — Microsoft Defender for Identity expands to Microsoft Entra Connect Server (formerly Azure AD Connect or AAD Connect). This includes new detections, security recommendations, and activity types in the “IdentityDirectoryEvents” table Advanced Hunting. Make sure to install the latest version of the sensor on the server with Entra ID Connect installed as you usually would do on domain controllers, etc.Updated 16/08/2023 — Microsoft Defender for Identity team released Active Directory Certificate Services (AD CS) sensor. AD CS is a Windows Server role that issues and manages public key infrastructure (PKI) certificates in secure communication and authentication protocols.Securing sensitive data and maintaining a robust cybersecurity posture is paramount in today’s digital landscape. Microsoft Defender for Identity (MDI) is a cutting-edge solution that offers advanced threat protection by leveraging cloud intelligence and behavioral analytics.This guide is your go-to resource for understanding the deployment process of Microsoft Defender for Identity (MDI).

As Microsoft’s attention and priorities pivot towards Azure, Microsoft Entra, Microsoft 365, and cloud-based services, on-premises AD has experienced limited advancements over the past decade, though it continues to receive support!The current trajectory leans towards adopting Microsoft Entra ID (formerly Azure AD), Microsoft Intune, and similar cloud-based services. However, a substantial number of organizations, especially those with large operations or complex infrastructures, will persist in a hybrid condition. This entails the continued deployment of synchronized on-premises AD in conjunction with Microsoft Entra ID (formerly Azure AD) for a considerable duration.A while ago, we wrote a step-by-step guide on how to install and evaluate Microsoft Advanced Threat Analytics (ATA). Advanced Threat Analytics (ATA) is an on-premises platform that helps protect your enterprise from multiple types of advanced targeted cyber attacks and insider threats.ATA was discontinued by Microsoft and was replaced with Microsoft Defender for Identity service. The mainstream support of Microsoft Advanced Threat Analytics (ATA) was ended on January 12, 2021, and the extended support will be continued until January 13, 2026.

To complete this step, you require the permissions of at least the Security Administrator role (Use always least privileged accounts).To create the MDI workspace, take the following steps:1) In the Microsoft 365 Defender portal, as a Security Administrator or Global Administrator, then navigate to Settings | Identities. Allow Microsoft 365 Defender (60 seconds) for the workspace to provision successfully.Preparing Microsoft Defender for Identity Workspace2) Next, we will add both the Directory Service Account (DSA) and action gMSA service accounts that we provisioned earlier.3) Go to Settings | Identities | Directory service accounts | + Add credentials as shown in the figure below.

Password Hash Sync is not in use.* Change Password for Entra Seamless SSO Account: Microsoft Entra seamless SSO account (AZUREADSSOACC) with passwords older than 90 days should have their passwords rotated to prevent attackers from exploiting these accounts to impersonate users.* Remove Resource-Based Constrained Delegation: If configured, resource-based constrained delegation on the Azure SSO account should be removed to prevent potential lateral movement attacks from on-premises Active Directory to Entra ID.Installing the MDI sensor on the Microsoft Entra ID Connect server follows the steps described below when installing it on domain controllers, etc. Take note of the following prerequisites:Install the latest version of the MDI Sensor, which is now version 2.240.18224.34815.Install the latest Entra ID Connect Server version 2.3.20.0 (Microsoft Entra Connect: Version release history).The audit 4624 logon event must be enabled on Entra Connect servers that are not Domain Controllers.Add a directory service account (e.g., gMSA) to Log on as a Service policy on the Entra Connect server.The MDI team is working on adding additional health checks around the Entra Connect server over the next few months. The new Microsoft Defender for Identity sensor for Entra ID Connect servers improves security by monitoring synchronization activities, detecting potential threats, and providing specific security alerts and posture recommendations for hybrid identity environments.Note: As of today, there is no estimated time for Microsoft Entra Cloud Sync support, but we hope it’s coming soon!PrerequisitesYou now understand that MDI is deployed to your on-premises AD domain to defend the hybrid identity infrastructure. Defender for Identity comprises the Defender for Identity cloud service, the Microsoft 365 Defender portal, and the Defender for Identity sensor.Deploy Microsoft Defender for IdentityTo follow this article, you need to have the following:1) Tenant – Microsoft 365 / Microsoft Entra (formerly Azure AD) Tenant. If you don’t have a tenant yet, you can create a free one here.2) Permissions:To create your Defender for Identity instance, you’ll need a Microsoft Entra ID (formerly Azure AD) tenant with at least one global/security administrator.You need to be a global administrator or security administrator on the tenant to access the Identity section on the Microsoft 365 Defender portal and be able to create the workspace. We strongly recommend using the Security Admin role and NOT the Global Admin. Please check the types of Defender for Identity security groups.Please note that any global administrator or security administrator on the tenant is automatically a Defender for Identity administrator.3) Active Directory (AD) – One or more AD domain controllers deployed on-premises or as an Azure IaaS VM:Suppose you still have Windows Server 2012 and 2012 R2. In that case, you should plan to upgrade those servers as Microsoft will no longer support the Defender for Identity sensor on devices running Windows Server 2012 and Windows Server 2012 R2.MDI sensors installed on Windows Server 2019 without the following update (KB4487044) will be automatically stopped.The domain controller can be a read-only domain controller (RODC).The Defender for Identity sensor requires a minimum of 2 cores, 6 GB of RAM, and 10
