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:

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