Implementing Zero Trust Architecture with Google's BeyondCorp: A Comprehensive Guideline

This tutorial provides a comprehensive, step-by-step guide for implementing Zero Trust Architecture using Google's BeyondCorp. This process is essential for enhancing network security by denying trust by default and encrypting and logging all traffic. Learn how to set up and configure this innovative solution to protect your IT environment from cybersecurity threats.

1. Understanding the Basics of BeyondCorp

BeyondCorp is a security model promoted by Google which shifts access controls from the network perimeter to individual devices and users. This permits employees to work securely from any location without the need for traditional VPNs.

2. Getting Started: Creating Your Google Identity-Aware Proxy (IAP)

Before deploying BeyondCorp, set up Google’s Identity-Aware Proxy (IAP) to manage access to your applications deployed in Google Cloud Platform. Here are the steps you need to follow:

• Go to the Google Cloud Console and click on 'IAM & Admin' -> 'Identity-Aware Proxy'.
• Select the project you want to secure with IAP.
• On the right-hand panel, toggle the 'Activate Cloud IAP' switch.

3. Setting Up Access Levels

Access levels in BeyondCorp determine who can access the applications in your network. Here are the steps to create access levels:

• Go to the 'Access Context Manager’ in the Google Cloud Console.
• Click 'Create an access level'.
• Fill the required details as per your needs and click 'CREATE'.

4. Setting Up Identity Platform

The Google Cloud Identity Platform is used to manage users and set authentication policies. Follow the steps below to set it up:

• Go to the Google Cloud Console and click on 'Identity Platform'.
• Add your first user and then click on 'ADD USER'.
• Next, set up the authentication by clicking 'Add a provider' and selecting 'Email & Password'.
• Turn on the 'Enable authentication' switch.

5. Connecting Your Applications

You can connect your applications to be protected by BeyondCorp. The steps will vary based on your setup.

6. Testing and Troubleshooting

Finally, after fully implementing BeyondCorp in your network, you should test the access policies and troubleshoot any issues that arise.

BeyondCorp's Zero-Trust Architecture is an excellent solution for companies that want to enhance their cybersecurity practices and protect against modern threats. By never trusting and always verifying, companies are taking proactive steps to protect their resources and sensitive information, irrespective of where their employees choose to work from.
