Google Cloud Professional Cloud Security Engineer — Question 47

You are the security admin of your company. Your development team creates multiple GCP projects under the "implementation" folder for several dev, staging, and production workloads. You want to prevent data exfiltration by malicious insiders or compromised code by setting up a security perimeter. However, you do not want to restrict communication between the projects.
What should you do?

Answer options

• A. Use a Shared VPC to enable communication between all projects, and use firewall rules to prevent data exfiltration.
• B. Create access levels in Access Context Manager to prevent data exfiltration, and use a shared VPC for communication between projects.
• C. Use an infrastructure-as-code software tool to set up a single service perimeter and to deploy a Cloud Function that monitors the "implementation" folder via Stackdriver and Cloud Pub/Sub. When the function notices that a new project is added to the folder, it executes Terraform to add the new project to the associated perimeter.
• D. Use an infrastructure-as-code software tool to set up three different service perimeters for dev, staging, and prod and to deploy a Cloud Function that monitors the "implementation" folder via Stackdriver and Cloud Pub/Sub. When the function notices that a new project is added to the folder, it executes Terraform to add the new project to the respective perimeter.

Correct answer: C

Explanation

The correct answer is C because it effectively establishes a single service perimeter to prevent data exfiltration while allowing communication between projects. Options A and B do not create a service perimeter, which is essential for security. Option D creates multiple perimeters, which contradicts the requirement of having a single security boundary.
