Then, starting in late June, they’ll receive the following prompt during sign-in: Global admins of eligible tenants will be notified through email. Due to the power admins have to make changes to your environment, they’re required to perform MFA every time they sign in.īased on usage patterns, Microsoft will start with organizations that are a good fit for security defaults, aka customers who aren’t using Conditional Access, haven’t used security defaults before, and aren’t actively using legacy authentication clients. Security defaults challenge users with MFA when necessary, based on factors such as location, device, role, and task. Microsoft introduced security defaults in October 2019 for new tenants, ensuring that new customers would be created and maintained with basic security hygiene in place – especially MFA and modern auth requirements – regardless of license, but tenants created before October 2019 were not included in security defaults and were vulnerable unless they explicitly enabled features like Conditional Access, Identity Protection, and MFA. Microsoft has begun the rollout of security defaults to existing customers who haven’t yet rolled out security defaults or Azure AD Conditional Access.

That’s it! as always, Happy PowerShelling. If you want to skip a couple of them, just enter their default domain names in the skiplist variable.

Finally, click on “Grant Admin Consent for Company Name.

Do the same for “Delegate Permissions”.

Search for “Policy” and click on “ and ”.

Choose “Microsoft Graph” and “Application permission”.

Go to “API Permissions” and click Add a permission.

You can search based on the ApplicationID.

Find your Secure App Model application.

Click on Azure Active Directory, now click on “App Registrations”.

You’ll also need to add some permissions: PermissionsĪs always you’ll need the secure application model for this script.

The users will then always get prompted on the method they configured for Security Defaults, you can use the script below to enable Security Defaults on all tenants, or a single tenant. You’ll have to go to the Multifactor admin page and click ‘enable’ for each user, after enabling Security Defaults. If you still want users to get prompted as each logon, as opposed to only some. Microsoft has a neat little table with the exact definition. If you want to know exactly what a risky event is, click here for some more information. Users get a little less trigger-happy on MFA prompts when they are unusual, so that should help you in your security practices. Microsoft believes that with the data they gathered around security and multi-factor authentication this is the best solution as it avoids creating a pattern of “muscle” memory where users are continually prompted for MFA and just start quickly clicking “Approve”. This has been done on purpose by our friends at Microsoft. So that last point is pretty big Users are not prompted for MFA each time they logon. This one is key: it requires users to logon with MFA only when the logon is seen as risky.It requires MFA for each login into a protected portal such as Azure, and the O365 admin portal.Protects all privileged account logons, like your global administrator.It also Disables legacy authentication protocols.This allows a user to take up to 14 days to register MFA. Requires users to register for Multi-factor authentication.Secure Defaults is Microsoft’s answer to our questions about deploying multi factor authentication to an entire tenant, of course security defaults does a lot more than just that.

In one of the groups I am in there was some confusion about how Secure Defaults work and how to deploy the Secure Defaults centrally, so I figured I would try to help with this.
