Changing the M365 Tenant Security Defaults through Azure

Microsoft has put out a new standard for security defaults in a tenant that harden default settings in the org. Security defaults make it easier to help protect your organization from these attacks with preconfigured security settings:

  • Requiring all users to register for Azure Multi-Factor Authentication.
  • Requiring administrators to perform multi-factor authentication.
  • Blocking legacy authentication protocols.
  • Requiring users to perform multi-factor authentication when necessary.
  • Protecting privileged activities like access to the Azure portal.

Now, there might be many reasons why you would not want these defaults enabled in your tenant, just remember that you will need to setup these things manually should you change the security defaults setting.
