To meet the requirements of rotating the master key every 45 days, achieving FIPS 140-2 Level 3 validation, and ensuring the master key is stored redundantly in multiple US regions, you should use Customer-managed encryption keys with Cloud HSM. Here’s how:

Set Up Cloud HSM:

Deploy Cloud HSM in your Google Cloud environment. Cloud HSM provides a hardware-based key management solution that meets FIPS 140-2 Level 3 compliance.

Create and Manage Keys:

Create your encryption keys in Cloud HSM. These keys can be managed and rotated per your policy requirements.

Key Rotation:

Set up a key rotation schedule to rotate the master key every 45 days. Cloud HSM allows you to automate this process.

Geographic Redundancy:

Ensure that your Cloud HSM configuration spans multiple regions within the US to achieve redundancy. This will ensure that your keys are available even if a particular region experiences an outage.

Compliance:

Cloud HSM’s FIPS 140-2 Level 3 validation ensures that your encryption keys are managed in a secure and compliant manner.

Benefits:

Security and Compliance: Meets stringent compliance requirements.

Automated Management: Simplifies key management and rotation.

Redundancy: Ensures high availability of keys across multiple regions.

To organize GCP projects based on different business units and manage IAM permissions, you should create an organization node and assign folders for each business unit. This approach allows you to logically separate projects under folders and apply IAM policies at the folder level.

Step-by-Step:

Create Organization Node: Ensure that your GCP account is linked to an organization.

Create Folders for Business Units:

Navigate to the GCP Console > IAM & Admin > Resource Manager.

Create a folder for each business unit under the organization node.

Move Projects to Folders:

Move existing projects into the respective folders according to the business unit.

Set IAM Policies:

Assign IAM roles and permissions at the folder level to manage access for each business unit independently.

Monitor and Manage: Use Cloud Audit Logs and other GCP tools to monitor the activities and ensure compliance with the organization’s policies.

Managing IAM Policies

Configure Binary Authorization:

Binary Authorization is a deploy-time security control that ensures only trusted container images are deployed on GKE. It uses attestations to verify the authenticity and integrity of the images.

Enable Binary Authorization in your project through the Google Cloud Console or using the gcloud command-line tool.

Define attestation policies that specify which attestors (trusted entities) must sign off on container images before deployment.

Set Up Attestors:

Create and configure attestors that will sign the container images. This involves generating cryptographic keys and setting up trusted authorities.

Attestors can be configured to sign images based on criteria such as vulnerability scanning results, compliance checks, and other security policies.

Create a Custom Organization Policy Constraint:

Define an organization policy constraint that enforces Binary Authorization across your GKE clusters.

This custom constraint ensures that all clusters in the organization must adhere to the Binary Authorization policy, preventing the deployment of unsigned or unauthorized container images.

Implement and Enforce the Policies:

Apply the Binary Authorization policy and the organization policy constraint to your GKE clusters.

Regularly review and update the policies and attestation rules to align with your security and compliance requirements.

TCP Proxy Load Balancing is implemented on GFEs that are distributed globally. If you choose the Premium Tier of Network Service Tiers, a TCP proxy load balancer is global. In Premium Tier, you can deploy backends in multiple regions, and the load balancer automatically directs user traffic to the closest region that has capacity. If you choose the Standard Tier, a TCP proxy load balancer can only direct traffic among backends in a single region. https://cloud.google.com/load-balancing/docs/load-balancing-overview#tcp-proxy-load-balancing

Uniform bucket-level access allows you to manage permissions at the bucket level, rather than at the object level. This simplifies permission management and ensures that access to objects is controlled consistently via IAM roles, without allowing uploaders full control over the objects.

Steps:

Enable Uniform Bucket-Level Access: In the Google Cloud Console, enable uniform bucket-level access for the Cloud Storage bucket.

Configure IAM Policies: Assign appropriate IAM roles to users and groups to control access to the bucket.

Audit Logging: Enable Cloud Audit Logs to track access and modifications to the bucket.

Managing access with IAM

In Google Cloud's Logging service, log entries are automatically routed to the _Default log bucket unless configured otherwise. When you create a new log bucket and intend to redirect all log entries from the _Default bucket to this new bucket, the most efficient approach is to modify the existing _Default sink to point to the new log bucket.​

Option A: Creating a new user-defined sink with filters replicated from the _Default sink is redundant and may lead to configuration complexities.​

Option B: Implementing exclusion filters on the _Default sink and then creating a new sink introduces unnecessary steps and potential for misconfiguration.​

Option C: Disabling the _Default sink would stop all log routing to it, but creating a new sink to replicate its functionality is inefficient.​

Option D: Editing the _Default sink to change its destination to the new log bucket ensures a seamless transition of log routing without additional configurations.​

Therefore, Option D is the most efficient and straightforward method to achieve the desired log routing.​

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.
