New Release Professional-Cloud-Security-Engineer Google Cloud Certified Questions

The problem requires ensuring that only images that have passed vulnerability scanning and meet corporate policies are allowed to be deployed to GKE, with the process being automated and integrated into the existing CI/CD pipeline.

Binary Authorization: This Google Cloud service is purpose-built to enforce deployment policies on images before they are run on Google Kubernetes Engine (GKE), Cloud Run, and other deployable platforms. It acts as a policy gate that prevents the deployment of non-compliant images.

Extract Reference: "Binary Authorization is a deploy-time security control that ensures only trusted container images are deployed on Google Kubernetes Engine (GKE), Cloud Run, and Anthos clusters." and "With Binary Authorization, you can require images to be signed by trusted authorities and enforce validation policies during deployment." (Google Cloud Documentation: "Binary Authorization overview" -

Artifact Analysis (part of Container Analysis): Artifact Analysis (which includes Container Analysis) provides vulnerability scanning capabilities for container images stored in Artifact Registry. It generates findings and metadata about vulnerabilities.

Extract Reference: "Container Analysis is a service that scans your images for known vulnerabilities and provides metadata about them." (Google Cloud Documentation: "Overview | Container Analysis" -

Binary Authorization can be configured to integrate with Artifact Analysis (or other attestors) to check for vulnerability scan results as part of its deployment policy.

Integration and Automation: Binary Authorization policies can require attestations before deployment. An attestation confirms that an image meets specific criteria (e.g., it has passed a vulnerability scan, it was signed by an approved CI/CD process, it adheres to corporate policies). Cloud Build can be configured to generate these attestations after a successful vulnerability scan (using Artifact Analysis). This fully automates the process and integrates directly into the CI/CD pipeline.

Extract Reference: "With Binary Authorization, you create a policy that enforces your requirements. The policy defines rules that govern deployment. For example, a policy can require all images to be signed by a trusted authority before deployment." (Google Cloud Documentation: "Binary Authorization overview" -

Let's evaluate the other options:

A. Custom script in Cloud Build... Fail the build: While scanning during the build is good practice (shift-left security), failing the build only prevents the image from being pushed. It doesn't prevent a developer or an automated process from manually deploying an old or non-compliant image that might already exist in Artifact Registry, or from bypassing the build system. The enforcement needs to happen at deployment time.

B. Configure GKE to use only images from a specific... trusted Artifact Registry repository. Manually inspect all images: Manually inspecting images is not automated and does not scale for a "large number of containerized applications." It also doesn't programmatically enforce vulnerability scan results or corporate policies.

D. Enable Artifact Analysis vulnerability scanning and regularly scan images... Remove any images that do not meet... before deployment: This describes scanning and remediation, which are important. However, it's a reactive approach ("remove any images") rather than a proactive enforcement ("only images that... are allowed to be deployed"). There's still a window where a non-compliant image could be deployed before it's removed. Binary Authorization is the enforcement gate.

Therefore, configuring Binary Authorization with a policy that integrates with Artifact Analysis (or requires attestations based on its findings) is the most robust, automated, and Google-recommended solution for enforcing deployment policies based on vulnerability scanning and corporate compliance.

The problem focuses on securing "super administrator accounts for the organization" when Cloud Identity is synced with Microsoft Entra ID and uses Entra ID for SSO. The key requirements are the principle of least privilege and strong authentication.

Principle of Least Privilege & Dedicated Accounts: Google's best practices strongly recommend creating dedicated, non-federated accounts for super administrators that are distinct from regular user accounts. These accounts should only be used for super administrator tasks and not for daily activities. This segregation ensures that the highest privilege accounts are isolated and adhere to the principle of least privilege by not having combined responsibilities.

Extract Reference: "Designate Organization Administrators... We recommend keeping your super admin account separate from your Organization Administrator group." and "Give super admins a separate account that requires a separate login. For example, user alice@example.com could have a super admin account alice-admin@example.com." and "Use the super admin account only when needed. Delegate administrator tasks to user accounts with limited admin roles. Use the least privilege approach..." (Google Cloud Documentation: "Super administrator account best practices | Resource Manager Documentation" -

Strong Authentication (Google 2-Step Verification): Even when using a third-party identity provider like Microsoft Entra ID for most users, Google recommends enforcing Google's own 2-Step Verification for the critical super administrator accounts. This provides a "break-glass" mechanism that is independent of the external IdP. If the Entra ID integration were to fail or become compromised, the Google-managed super administrator accounts, protected by Google's own 2SV, would still be accessible for emergency recovery.

Extract Reference: "Even when using the legacy SSO profile, super admins can't sign in with SSO in these cases: Admin console. When super administrators try to sign in to an SSO-enabled domain via admin.google.com, they must enter their full Google administrator account email address and associated Google password (not their SSO username and password), and click Sign in to directly access the Admin console. Google doesn't redirect them to the SSO sign-in page." (Google Cloud Identity Help: "Super administrator SSO" - - This highlights that super admin accounts can bypass SSO for direct Admin console access, making Google 's 2SV crucial.

Extract Reference: "It's especially important for super admins to use 2SV because their accounts control access to all business and employee data in the organization. Protect your business with 2-Step Verification. Use security keys for 2-Step Verification." (Cloud Identity Help: "Security best practices for administrator accounts" -

Options C and D are incorrect because combining "organization administrator" (IAM role for GCP resources) and "super administrator" (Google Workspace/Cloud Identity domain-level control) privileges violates the principle of least privilege. Option A is less secure than B because relying solely on Entra ID's 2SV for super administrators means a compromise of Entra ID or an outage would leave the Google Cloud organization vulnerable without an independent break-glass mechanism.

To ensure that PII data is separated from non-PII data, using Cloud Pub/Sub and Cloud Functions to trigger a scan by the Data Loss Prevention (DLP) API is an effective approach. This method allows for automated detection and handling of PII.

Steps:

Set Up Cloud Pub/Sub: Configure a Cloud Pub/Sub topic to receive notifications whenever a file is uploaded to the shared Cloud Storage bucket.

Deploy Cloud Functions: Create a Cloud Function that is triggered by the Pub/Sub topic. This function will invoke the DLP API to scan the uploaded file for PII.

Move Detected PII Files: If the scan detects PII, the Cloud Function will move the file to a secure Cloud Storage bucket accessible only by the administrator.

Set Permissions: Ensure that appropriate permissions are set on the Cloud Storage buckets to restrict access to files containing PII.

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.
