Configure Cloud Interconnect:

Cloud Interconnect provides high-bandwidth, low-latency connectivity between your on-premises network and Google Cloud. You can choose between Dedicated Interconnect or Partner Interconnect depending on your requirements.

Set up the physical connection and establish the interconnect through the Google Cloud Console or by working with a partner.

Set Up HA VPN:

High Availability (HA) VPN provides a robust, reliable VPN connection to Google Cloud with SLA guarantees. This is crucial for ensuring secure and high-bandwidth connectivity.

Configure two VPN tunnels to ensure redundancy and failover capabilities.

Update Default Route:

Replace the default 0.0.0.0/0 route in your Google Cloud VPC to direct traffic to your on-premises network via the Cloud Interconnect and HA VPN setup.

This ensures all internet-facing traffic is securely routed through your on-premises internet connection.

Ensure Proper Security and Routing Policies:

Implement appropriate firewall rules and security policies on both Google Cloud and on-premises environments to control traffic and ensure secure communication.

Monitor the traffic and connectivity status to maintain optimal performance and security.

To evaluate Google Cloud Platform (GCP) for PCI compliance and identify Google's inherent controls, you should review the "Google Cloud Platform: Customer Responsibility Matrix". This document provides detailed information about the shared responsibility model, outlining the security controls managed by Google and those that are the responsibility of the customer.

Steps to access and use the document:

Access the Document:

Go to the Google Cloud compliance resource center.

Locate the "Customer Responsibility Matrix" for PCI DSS compliance.

Review Inherent Controls:

The document lists various controls and specifies whether they are managed by Google, the customer, or both.

It covers different aspects such as infrastructure security, data protection, and compliance requirements.

Analyze PCI Compliance:

Use the matrix to understand which PCI DSS requirements are inherently addressed by Google Cloud.

Identify the controls you need to implement and manage as a customer to ensure full compliance.

By reviewing this document, you can gain a comprehensive understanding of the inherent controls provided by Google Cloud and the responsibilities you must fulfill to achieve PCI compliance.

PCI DSS Compliance on Google Cloud

Use Pub/Sub and Cloud Functions to trigger a Cloud Data Loss Prevention scan every time a file is uploaded to the administrator's bucket. If the scan does not detect PII, have the function move the objects into the shared Cloud Storage bucket:

Configure a Pub/Sub topic to publish notifications when new files are uploaded to the administrator's bucket.

Create a Cloud Function that is triggered by the Pub/Sub topic. This function uses the Cloud Data Loss Prevention (DLP) API to scan the uploaded files for PII.

If the scan does not detect PII, the function moves the file to the shared Cloud Storage bucket. This ensures that only non-sensitive data is accessible to analysts, while PII remains secure in the administrator's bucket.

Comprehensive and Detailed Explanation From Exact Extract:

The most efficient and recommended way to achieve real-time/near real-time ingestion of logs (including Google Workspace Audit Logs, which feed into Cloud Logging) to a third-party system is by using a Cloud Logging sink to a Pub/Sub topic.

Cloud Logging Sink: Creates a stream of logs filtered by type (e.g., authentication events).

Pub/Sub Topic: A messaging service that acts as a reliable, real-time message queue.

SIEM Subscription: The SIEM system can subscribe directly to the Pub/Sub topic, receiving log events as soon as they are published, meeting the real-time requirement.

Extracts:

"Cloud Logging sinks let you route logs to destinations like Cloud Storage, BigQuery, or Pub/Sub... Routing logs to Pub/Sub enables real-time streaming of log data for consumption by external services or applications, such as a third-party SIEM." (Source 7.1)

Option B (polling) and Option D (Cloud Storage bucket) are batch-oriented methods, which do not meet the real-time/near real-time requirement.
