## Overview

Phishing-resistant MFA SHALL be required for highly privileged roles.

Rationale: This is a backup security policy to help protect privileged access to the tenant if the Conditional Access policy, which requires MFA for all users, is disabled or misconfigured.

#### Remediation action:

Create a Conditional Access policy enforcing phishing-resistant MFA for highly privileged roles. Configure the following policy settings in the new Conditional Access policy, per the values below:

1. In **Entra** under **Protection** and **Conditional Access**, select **[Policies](https://entra.microsoft.com/#view/Microsoft_AAD_ConditionalAccess/ConditionalAccessBlade/~/Policies/fromNav/)**.
2. Click on **New policy**
3. Under **New Conditional Access policy**, configure the following policy settings in the new Conditional Access policy, per the values below:
    * Users > Include > Select users and groups > Directory roles > select each of the roles listed in the **[Highly Privileged Roles](https://github.com/cisagov/ScubaGear/blob/main/PowerShell/ScubaGear/baselines/aad.md#highly-privileged-roles)** listed.
    * Target resources > Cloud apps > **All cloud apps**
    * Access controls > Grant > Grant Access > Require authentication strength > **Phishing-resistant MFA**
4. Click **Save**.
