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.

"Isolate VMs using service accounts when possible" "even though it is possible to uses tags for target filtering in this manner, we recommend that you use service accounts where possible. Target tags are not access-controlled and can be changed by someone with the instanceAdmin role while VMs are in service. Service accounts are access-controlled, meaning that a specific user must be explicitly authorized to use a service account. There can only be one service account per instance, whereas there can be multiple tags. Also, service accounts assigned to a VM can only be changed when the VM is stopped." https://cloud.google.com/solutions/best-practices-vpc-design#isolate-vms-service-accounts

A. Create a Cloud Build pipeline that will monitor changes to your container templates in a Cloud Source Repositories repository. Add a step to analyze Container Analysis results before allowing the build to continue:

Use Cloud Build to automate your CI/CD pipeline.

Integrate Container Analysis to scan container images for vulnerabilities during the build process.

If vulnerabilities are found, configure the build to fail, preventing deployment of insecure containers.

E. In your CI/CD pipeline, add an attestation on your container image when no vulnerabilities have been found. Use a Binary Authorization policy to block deployments of containers with no attestation in your cluster:

Use Binary Authorization to enforce deploy-time security policies.

Configure your CI/CD pipeline to generate attestations for container images that pass vulnerability scans.

Binary Authorization will then block deployments of any containers without valid attestations, ensuring only secure images are deployed.

Security Command Center (SCC) in Google Cloud provides several features to help organizations detect and respond to security threats and misconfigurations.

Event Threat Detection: This feature continuously monitors and analyzes system logs to detect potential threats such as crypto mining. It uses machine learning and threat intelligence to identify suspicious activities and generate alerts.

Security Health Analytics: This feature helps identify common misconfigurations and compliance violations that could impact security. It provides visibility into security posture and helps remediate issues related to misconfigurations in your Google Cloud environment.

By using both Event Threat Detection and Security Health Analytics, you can effectively monitor for crypto mining activities and detect common misconfigurations that could compromise security.

The Standard Tier network only provides regional load balancing, while the Premium Tier supports global load balancing with a single anycast IP address. To distribute requests across multiple regions, you need to use the Premium Tier and update the load balancer configuration accordingly.

Steps:

Upgrade to Premium Tier: Update the load balancer to use the Premium Tier network in the Google Cloud Console.

Add New Instance Group: Add the instance group in the new region (us-east-2) to the backend configuration of the existing load balancer.

Verify Configuration: Ensure that the frontend configuration of the load balancer uses a single external IP address for global distribution.

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.

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.

Objective: Understand the security characteristics of VPC peering.

Security Characteristics:

Non-transitive Peering: VPC peering connections are non-transitive. This means that peering is strictly between two VPC networks. If VPC A is peered with VPC B, and VPC B is peered with VPC C, VPC A cannot communicate with VPC C unless a direct peering connection is established.

Inter-Organization Peering: VPC peering allows you to connect VPC networks across different Google Cloud Platform organizations, facilitating private communication between distinct organizational units.

These characteristics ensure controlled and secure connectivity between VPC networks while preventing unintended data exposure.
