Google Professional-Cloud-Security-Engineer Exam With Confidence Using Practice Dumps

Objective: Implement external web application protection and validate policy changes before enforcement.

Solution: Use Google Cloud Armor's preconfigured rules in preview mode.

Steps:

Step 1: Open the Google Cloud Console.

Step 2: Navigate to the Google Cloud Armor section.

Step 3: Create or select a security policy.

Step 4: Apply preconfigured rules to the policy.

Step 5: Enable preview mode to simulate the effects of the rules without enforcing them.

Step 6: Monitor the logs to validate the policy changes.

Google Cloud Armor's preview mode allows you to test and validate the impact of security policies on your application traffic before applying them, ensuring that they work as intended without disrupting the service.

Workload Identity is the Google-recommended method for GKE workloads to access Google Cloud services. It eliminates the need for manual management of service account keys (JSON files), which are a major security risk if leaked.1

According to Google Cloud Documentation (Workload Identity Federation for GKE):

"Workload Identity is the recommended way for your workloads running on GKE to access Google Cloud services in a secure and manageable way. It allows a Kubernetes service account in your GKE cluster to act as a Google IAM service account.2 When you use Workload Identity, you don't need to manage service account keys or store them as Kubernetes secrets."

Why other options are incorrect:

A is incorrect: Service account keys are long-lived and difficult to rotate. Using them increases the risk of credential theft.

C & D are incorrect: Attaching a service account to a Node gives every pod running on that node the same permissions. This violates the Principle of Least Privilege because different workloads on the same node should have different permissions.

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.
