Microsoft 365 Administration Foundations

Security in Microsoft 365 can feel like a nonstop stream of alerts, dashboards, and "urgent" recommendations. This book helps you turn that noise into a clear, repeatable security workflow using Microsoft Defender XDR as your command center.
Manage Security and Threats Using Microsoft Defender XDR is part of the Microsoft 365 Administration Foundations series, built for Microsoft 365 admins and security-minded IT pros who want practical guidance, not theory. You will learn how to prioritize real risk with Exposure Management and Microsoft Secure Score, investigate incidents and alerts with confidence (including guided hunting), and use threat intelligence to tighten your posture before the next attack hits.
You will also build strong protection across the areas attackers target most:

• Email and collaboration security with Defender for Office 365 (policies, investigations, simulations, and response)
• Endpoint protection with Defender for Endpoint (onboarding, settings, and vulnerability response)
• SaaS visibility and control with Microsoft Defender for Cloud Apps (connectors, policies, discovery, and issue response)
