Microsoft 365 Tenant Administration & Security Hardening

Frequently Asked Questions (Microsoft 365 Administration)

Why is disabling legacy authentication critical in Microsoft 365?

Legacy protocols (like POP3, IMAP, and basic SMTP) do not support Multi-Factor Authentication (MFA), making them primary targets for credential stuffing and brute-force attacks.

What is the difference between Security Defaults and Conditional Access?

Security Defaults provide baseline MFA rules for all users without customization. Conditional Access allows granular rules based on user risk, IP location, device compliance, and client application.

How do you enforce SharePoint permissions governance safely?

SharePoint sites should be restricted using security groups rather than individual user permissions, with external sharing links set to expire automatically.
