Google Updated Professional-Cloud-Security-Engineer Exam Questions and Answers by aliyah

To access a user's Google Drive on their behalf without relying on the user's credentials and following Google-recommended practices, you should use a service account with domain-wide delegation.

Create a Service Account:

Go to the Cloud Console, navigate to IAM & Admin > Service Accounts.

Click "Create Service Account" and provide necessary details.

Grant Domain-Wide Delegation:

Edit the service account to enable "G Suite Domain-wide Delegation".

Download the JSON key file.

Configure API Access in G Suite:

Go to the Google Admin Console.

Navigate to Security > API Controls > Domain-wide Delegation.

Add a new API client and use the client ID from the service account.

Authorize the necessary API scopes (e.g., https://www.googleapis.com/auth/drive).

Implement in Application:

Use the Google API Client Library for the desired language.

Load the service account credentials and perform user impersonation to access Google Drive.

Access Google Cloud Console:

Log in to the Google Cloud Console with administrative privileges.

Navigate to the "IAM & Admin" section.

Set Session Length Timeout:

Go to the "Settings" page within IAM & Admin.

Locate the "Session control" settings.

Configure the session length timeout to a shorter duration, such as 15 or 30 minutes. This ensures that user sessions expire automatically after the specified time of inactivity.

Apply and Enforce the Policy:

Save the changes and ensure the new session timeout policy is applied across all users and services.

Communicate the new policy to employees, highlighting the importance of session security and the rationale behind the change.

Additional Security Measures:

Consider implementing additional measures such as automatic screen locks and secure session management practices.

Educate employees on the importance of logging out of their sessions and securing their devices when not in use.

To ensure that data is encrypted while in use by the virtual machines (VMs) and enforce this policy across your organization, you should use Confidential VM instances. Here are the steps:

Enable Confidential VM:

Ensure that Confidential VMs are available in your selected regions and enabled for your project.

Set Organization Policy:

Implement an organization policy to enforce the use of Confidential VM instances for all VMs across your organization.

Use the Google Cloud Console or the gcloud command-line tool to set this policy. Example command:

gcloud resource-manager org-policies set-policy my_policy.yaml

Example my_policy.yaml:

name: organizations/1234567890/policies/compute.requireConfidentialCompute spec: rules: - enforce: true

Verify and Monitor:

Ensure that all newly created VMs across your organization are Confidential VMs.

Regularly monitor compliance through the Google Cloud Console and set up alerts if non-compliant VMs are created.

Benefits:

Data Encryption in Use: Confidential VMs ensure that data is encrypted not just at rest and in transit but also while in use.

Policy Enforcement: Organization policies provide a way to enforce security configurations across all projects under your organization.

To ensure that a Compute Engine instance does not have access to the internet or to any Google APIs or services, you need to disable the following settings:

Public IP: Disabling the public IP address ensures that the instance does not have a direct connection to the internet. Without a public IP address, the instance cannot be accessed from or communicate with the internet directly.

Private Google Access: Disabling Private Google Access ensures that the instance does not have access to Google APIs and services through the internal Google network. Private Google Access allows instances without a public IP to reach Google APIs and services using private IP addresses, but disabling it will block this path.

Disabling these settings will effectively isolate the instance from both the public internet and Google's internal API services.
