The company has branch offices in New York. London, and Singapore. Fabrikam has remote users located across the globe. The remote users access company resources, including cloud resources, by using a VPN connection to a branch office.

The network contains an Active Directory Domain Services (AD DS) forest named fabrikam.com that syncs with an Azure AD tenant named fabrikam.com. To sync the forest, Fabrikam uses Azure AD Connect with pass-through authentication enabled and password hash synchronization disabled. The fabrikam.com forest contains two global groups named Group1 and Group2.

All the users at Fabrikam are assigned a Microsoft 365 E5 license and an Azure Active Directory Premium Plan 2 license. Fabrikam implements Microsoft Defender for Identity and Microsoft Defender for Cloud Apps and enables log collectors.

Fabrikam has an Azure subscription that contains the resources shown in the following table.

• Microsoft Defender for Cloud

• Microsoft Sentinel

Fabrikam identifies the following business requirements:

• Use the principle of least privilege, whenever possible.

• Minimize administrative effort.
