You have a Microsoft 365 E5 subscription that uses Microsoft Defender XDR and contains a user named User1. You need to ensure that User1 can manage…

The Security Administrator role is the appropriate choice as it grants the necessary permissions to manage security configurations across Microsoft 365 services. This role allows a user to manage security policies and settings in both Microsoft Defender XDR and Microsoft Intune. Specifically, it provides the required access to create and manage custom detection rules in advanced hunting and to configure Endpoint security policies (such as antivirus, firewall, and EDR) in the Intune admin center. Among the given options, this is the role that meets all requirements while adhering to the principle of least privilege, as the other roles are either too restrictive or irrelevant.

A. Desktop Analytics Administrator: This role is specific to managing the Desktop Analytics service for Windows client deployment insights and is unrelated to security policy management.

B. Security Operator: This role is focused on security operations, such as managing alerts and incidents. It has read-only permissions for policies and cannot create or modify them.

D. Cloud Device Administrator: This role manages the lifecycle of devices in Azure AD and Intune (e.g., enrolling, disabling, deleting) but lacks the specific permissions to manage security policies.
