Google Cloud Certified Professional-Cloud-Security-Engineer Question # 39 Topic 4 Discussion

To ensure that payment information is encrypted between the customer’s browser and Google Cloud Platform during checkout, the company should configure an SSL certificate on an L7 (Layer 7) Load Balancer. Here’s why this is the best solution:

SSL/TLS Termination: An L7 Load Balancer can handle SSL/TLS termination, which means it can decrypt HTTPS traffic, offloading the work from the backend servers. This is essential for handling encrypted connections securely.

HTTPS Configuration: By configuring an SSL certificate, the load balancer ensures that all traffic between the customer’s browser and the application is encrypted using HTTPS.

Security Best Practices: Using an L7 Load Balancer with an SSL certificate aligns with best practices for securing web applications, particularly for e-commerce sites handling sensitive payment information.

Managed Certificates: Google Cloud offers managed SSL certificates, which simplifies the process of obtaining, deploying, and renewing SSL certificates.

Implementation Steps:

Obtain an SSL certificate.

Configure the L7 Load Balancer in the GCP Console.

Associate the SSL certificate with the load balancer.

Ensure that the backend services are configured to handle HTTPS traffic.
