Fighting Identity-Based Attacks in Entra ID for Defenders
Identity is the primary perimeter to secure — and also the most targeted in cloud. In this session, we’ll walk through the most common identity-based attacks in Microsoft Entra, including token theft, consent phishing, credential stuffing, and Business Email Compromise (BEC).
Using realistic scenarios, we’ll explore how to defend against these threats with M365 Business Premium, E3, and E5 — what’s actually possible across different licensing tiers. We’ll also reflect on how identity is now serving as the primary entry point for attackers.
With over 345 million daily password-based attacks and BEC losses in the billions, it’s no longer a matter of if you’ll be targeted — but when.
What you’ll learn:
• Key attack techniques targeting Entra tenants
• How Microsoft 365 licensing impacts defense strategies
• Actionable protection tactics for different business tiers
This session is for IT admins, Cloud architects, and Security defenders looking to strengthen their protection strategies
