4.1.1.1 Ensure 2-Step Verification (MFA) is enforced for all users in administrative roles

Profile Applicability

• Enterprise Level 1

Description

Enforce 2-Step Verification (Multi-Factor Authentication) for all users assigned administrative roles. These include roles such as:

• Help Desk Admin
• Groups Admin
• Super Admin
• Services Admin
• User Management Admin
• Mobile Admin
• Android Admin
• Custom Admin Roles

Rationale

Add an extra layer of security to users accounts by asking users to verify their identity when they enter a username and password. 2-Step Verification (Multi-factor authentication) requires an individual to present a minimum of two separate forms of authentication before access is granted. 2-Step Verification provides additional assurance that the individual attempting to gain access is who they claim to be. With 2-Step Verification, an attacker would need to compromise at least two different authentication mechanisms, increasing the difficulty of compromise and thus reducing the risk.

Impact

Implementation of 2-Step Verification (multi-factor authentication) for all users in administrative roles will necessitate a change to user routine. All users in administrative roles will be required to enroll in 2-Step Verification using phone, SMS, or an authentication application. After enrollment, use of 2-Step Verification will be required for future access to the environment.

Audit

To verify this setting via the Google Workspace Admin Console:

1. Log in to https://admin.google.com as an administrator
2. Go to Security and click on 2-Step Verification
3. Select the appropriate group with ALL ADMIN ROLES -- Create this group if needed
4. Under Authentication, ensure Allow users to turn on 2-Step Verification is checked
5. Ensure Enforcement is set to On
6. Ensure New user enrollment period is set to 2 weeks
7. Under Frequency, ensure Allow user to trust device is unchecked
8. Under Methods, ensure Any except verification codes via text, phone call is selected
