Why is adaptive MFA authentication important in Microsoft 365?
+
By default, per-user MFA uses basic authentication methods such as SMS (text) and call verification for initial authentication. However, these methods are more vulnerable to attacks like SIM swapping, potentially compromising your Microsoft 365 security.
Adaptive MFA is the strongest way to protect your Microsoft 365 accounts. It dynamically adjusts authentication requirements based on factors like user, role, location, etc. and uses pre-defined conditional access policies to enhance security. With adaptive MFA, you can configure multiple strong authentication methods and enforce policies based on user licenses.
- Navigate to Microsoft Entra admin center.
- Navigate to âConfigure Multi-factor authenticationâ under Setup and click on it.
- Click on âGet startedâ and configure your adaptive MFA policy.
- Configure your adaptive policy with recommended authentication methods and other conditions based on your requirements.
- Review and click âSave configurationâ.
Admins may need to disable MFA for users in certain scenarios, especially to create break glass accounts. These accounts are backup accounts with high admin privileges that can be used to access the organization's data in critical situations, such as when all users are blocked by MFA failing or during a cyberattack.
However, disabling MFA for users in Microsoft 365 is not recommended that can lead to identity compromises. Therefore, it is crucial to closely manage MFA usage activities in your organization.
- Deploy the âMFA disabled usersâ alert policy from the Alerts > Policy templates section in a few clicks. This policy will trigger alerts whenever MFA of a user disabled in your organization.
- Here's a pro tip: For enhanced multi-factor authentication management utilize the alert preview console. It analyzes past events in your organization and suggests possible alerts. You can customize your alert policies with perfect threshold limits and settings to address specific security threats, like an unusual number of MFA disabling activities.
