Google Professional-Cloud-Security-Engineer Exam With Confidence Using Practice Dumps

To grant read access to a third-party disk image stored in an external Google Cloud organization so it can be deployed into a VPC Service Controls perimeter, you need to update the service perimeter to allow egress traffic from your projects to the external project.

Update the Service Perimeter:

Go to the Google Cloud Console, navigate to Security > VPC Service Controls.

Select the appropriate service perimeter that includes your image repository project.

Configure Egress Policy:

Within the perimeter settings, configure the egressTo field to allow traffic to the external project.

Set the identityType to ANY_IDENTITY to permit any principal to access the external project for this specific egress rule.

Specify External Project and Service:

In the egressFrom field, include the external Google Cloud project number as an allowed resource.

Set the serviceName to compute.googleapis.com to specifically allow access to the Compute Engine service in the external project.

This configuration permits your internal projects to read the disk image from the external project while maintaining the security boundaries established by the service perimeter.

Understanding Unmanaged Users:

Unmanaged users are those who have created Google Cloud accounts using their company email addresses outside of the organization's management (e.g., through GCDS).

Challenge:

The goal is to bring these unmanaged accounts under your company's control without disrupting their existing accounts and access.

Using the Transfer Tool:

Google provides a transfer tool specifically designed to migrate unmanaged users to a managed state.

This tool allows administrators to invite unmanaged users to join the organization's Google Cloud Identity or Google Workspace account.

Steps to Use the Transfer Tool:

Step 1: Access the transfer tool from the Google Admin console.

Step 2: Identify the unmanaged users using their email addresses.

Step 3: Send invitations to these users to transfer their accounts.

Step 4: Users accept the invitations, allowing their accounts to be managed under the organization's domain.

Benefits:

This method ensures a smooth transition for users without losing access to their existing data and services.

It aligns with best practices for managing user accounts in a corporate environment.

Objective: Encrypt data using envelope encryption.

Solution: Follow the envelope encryption process.

Steps:

Step 1: Generate a Data Encryption Key (DEK) locally. The DEK is used to encrypt the actual data.

Step 2: Encrypt the data using the DEK.

Step 3: Use a Key Encryption Key (KEK) to wrap the DEK. The KEK is used to encrypt the DEK.

Step 4: Store the encrypted data and the wrapped DEK. This ensures that the data can be securely decrypted in the future using the KEK to unwrap the DEK.

Envelope encryption enhances security by adding an additional layer of encryption to the data encryption key, which is particularly useful for managing large volumes of encrypted data.
