Pearson Professional-Cloud-Security-Engineer New Attempt

App Engine ingress firewall rules are available, but egress rules are not currently available. Per requirements 1.2.1 and 1.3.4, you must ensure that all outbound traffic is authorized. SAQ A-EP and SAQ D–type merchants must provide compensating controls or use a different Google Cloud product. Compute Engine and GKE are the preferred alternatives. https://cloud.google.com/solutions/pci-dss-compliance-in-gcp

To allow a large number of users to access the GCP Console while keeping the existing Active Directory or LDAP server for identity management, use Google Cloud Directory Sync (GCDS).

Install GCDS:

Download and install Google Cloud Directory Sync from here.

Configure GCDS:

Set up the synchronization by specifying the LDAP server details and the Google domain.

Map the LDAP attributes to Google attributes to ensure user data is synchronized correctly.

Run Synchronization:

Perform an initial synchronization to populate the Google domain with existing users from the LDAP server.

Schedule regular synchronizations to keep the data up-to-date.

Benefits:

Automated Sync: Ensures that user data is consistently updated without manual intervention.

Secure Access: Users can log in to the GCP Console using their existing credentials, enhancing security and user experience.

Enable Dry Run Mode: Start by enabling the dry run mode for your VPC Service Controls perimeter. This mode allows you to test changes without actually enforcing them, thus preventing any disruption to your current setup.

Add Access Level: Add your new access level to the dry run configuration. This way, you can monitor how the new access level would behave and interact with your existing setup without any real impact.

Vetting Process: Carefully vet the new access level by analyzing logs and monitoring the behavior in the dry run mode. Ensure that the new configuration meets your security and operational requirements.

Update Perimeter: Once you are confident that the new access level will not disrupt existing services and meets all requirements, update the actual perimeter configuration with the new access level. This approach minimizes risk by allowing you to test changes before they take effect, ensuring seamless updates with minimal disruption. References:

A service account represents an identity associated with an instance. Only one service account can be associated with an instance. You control access to the service account by controlling the grant of the Service Account User role for other IAM principals. For an IAM principal to start an instance by using a service account, that principal must have the Service Account User role to at least use that service account and appropriate permissions to create instances (for example, having the Compute Engine Instance Admin role to the project).
