A company is implementing a Zero Trust security model using Microsoft 365 Defender. Which THREE of the following are key principles they should follow?
Minimizes the blast radius of a breach.
Why this answer
Zero Trust mandates least privilege access, and Microsoft 365 Defender integrates with Azure AD Privileged Identity Management (PIM) to enforce Just-In-Time (JIT) and Just-Enough-Access (JEA) policies. This ensures users receive only the permissions necessary for a specific task, for a limited duration, reducing the risk of lateral movement and privilege escalation.
Exam trap
The trap here is that candidates often confuse Zero Trust with traditional perimeter-based security, mistakenly believing that internal network origin or known user status should be trusted implicitly, when in fact Zero Trust requires explicit verification for every access request regardless of source.
