To reduce the scope of systems subject to PCI audit standards, segregate the cardholder data environment (CDE) into a separate GCP project. This ensures that only the project containing the CDE will be subject to PCI DSS compliance, reducing the audit scope for other projects.

Create Separate GCP Project:

Go to the Cloud Console, navigate to IAM & Admin > Manage Resources.

Click "Create Project" and set up a new project for the CDE.

Migrate CDE:

Transfer the systems processing, storing, or transmitting cardholder data to the new project.

Apply PCI DSS Controls:

Implement PCI DSS required controls on the new project.

Use appropriate security measures such as firewalls, access controls, and encryption.
