A mid-sized company is transitioning to a Zero-Trust security model in Google Cloud (GCP). Previously, they relied on perimeter security but lacked identity-based access controls, making them vulnerable to unauthorized access and insider threats. Their new Zero-Trust strategy focuses on:
For all resources in this lab, we are using the GCP
us-east1
region.
In this GCP lab, you will complete the following exercises:
Navigate to Google Cloud Console and open IAM & Admin.
Under Users, select Bulk Import.
Download the CSV template and populate it with user details.
Modify the file to add users in bulk. Ensure fields like username, display name, and initial password are filled.
Upload the CSV file and submit the bulk creation request.
Create a new IAM Group named Management and add the imported users.
Navigate to Google Cloud Console and open IAM & Admin.
Under IAM Policies, click Create Policy and name it Zero-Trust Access Control.
Navigate to Security > Identity-Aware Proxy in the Google Cloud Console.
Enable IAP for applications that require Zero-Trust access.
Configure access policies to enforce context-aware authentication.
Navigate to Google Cloud Console and open IAM & Admin.
Under Security Settings, enable Multi-Factor Authentication (MFA).
Require authentication via Google Authenticator or hardware security keys.
Apply MFA enforcement to all users in the Management IAM Group.
Open Google Cloud Console and navigate to VPC Networks.
Private Service Connect ensures private connectivity to GCP services without exposing workloads to the internet.
Steps to implement:
Navigate to Google Cloud Console and open Cloud Logging.
SELECT * FROM audit_logs WHERE eventName = 'ConsoleLogin' AND riskLevel != 'None'
By following these steps, you successfully implemented a Zero-Trust Architecture in GCP, securing identity access and network traffic. The organization now has a robust identity-based security model, protecting against unauthorized access and insider threats.
