4.2.2.1 Ensure blocking access from unapproved geographic locations

Profile Applicability

Enterprise Level 1

Description

Restrict access to selected Google applications by geographic location.

Rationale

Restricting access to known/approved geographic locations is a simple way to limit where attacks can originate from. Especially for smaller organizations that do not need global access to applications.

Impact

Valid/approved users traveling to a geographic region outside of those defined in the Access Level will not be able to access their applications.

Audit

To verify this setting via the Google Workspace Admin Console:

Verify an appropriate Access Level has been defined

Log in to https://admin.google.com as an administrator
Select Security
Select Access and Data Control
Select Context-Aware Access
Select Access levels
Review the list of Access Levels displayed and determine if there is an appropriate restriction on geographic access

Verify the appropriate Access Level has been assigned to the application(s) that need the restriction

Log in to https://admin.google.com as an administrator
Select Security
Select Access and Data Control
Select Context-Aware Access
Select Assign access levels
Review the list of Google Applications displayed and make sure the appropriate access level for geographic access is assigned to each

NOTE: CIS recommends geographically restricting access to the following Google applications at minimum:

Admin Console
Drives and Docs
Gmail
Google Vault

Remediation
