Managing IAM permissions at the KeyRing level is more efficient and scalable compared to managing them at the individual Key level. By creating a single KeyRing and placing all encryption keys within it, you can apply uniform IAM permissions to the entire KeyRing, simplifying the management of permissions.

Steps:

Create a KeyRing: Set up a single KeyRing in Cloud KMS for all the encryption keys required for the persistent disks.

Create Encryption Keys: Generate the necessary encryption keys within this KeyRing.

Set IAM Permissions: Assign IAM roles and permissions to the KeyRing to manage access control at this level, ensuring that all keys within the KeyRing inherit these permissions.

The standard and most efficient way to stream logs from Google Cloud (including Workspace logs that are shared with Google Cloud) to an external SIEM is via Cloud Logging Sinks pointing to Pub/Sub.5

According to Google Cloud Documentation (Architecture for exporting Cloud Logging logs):

"To stream logs to a third-party SIEM in real-time, you should create a log sink in Cloud Logging. The sink filters for specific logs (e.g., resource.type="audited_resource" and methodName:"login") and exports them to a Pub/Sub topic. The SIEM can then subscribe to this topic to pull events immediately as they are generated."

Why other options are incorrect:

A is incorrect: Exporting to Cloud Storage is for long-term archiving/compliance and is not real-time (it usually involves batched files every few hours).

C is incorrect: Polling via CLI is not scalable, introduces latency, and is prone to failure in production environments.

D is incorrect: Google Workspace does not have a native "direct push" feature for SIEM endpoints; it typically requires an intermediate step like Pub/Sub or BigQuery.

Objective: Ensure VMs can access Cloud Storage without reaching the public internet.

Solution: Enable Private Google Access on the VPC network, allowing VMs with only internal IP addresses to access Google APIs and services privately.

Steps:

Step 1: Open the Google Cloud Console.

Step 2: Go to the VPC Network section.

Step 3: Select the relevant VPC network and subnet.

Step 4: Enable Private Google Access for the subnet.

Private Google Access ensures that instances can access Google APIs and services (such as Cloud Storage) over a private network connection, without requiring a public IP address.

To ensure that Vertex AI Workbench Instances are automatically kept up-to-date and that users cannot alter operating system settings, implementing specific organization policies is essential.​

Option A: Enabling VM Manager and adding Compute Engine instances assists in managing and monitoring VM instances but does not enforce automatic updates or restrict user modifications to the operating system.​

Option B: Enforcing the disableRootAccess organization policy prevents users from gaining root access, thereby restricting unauthorized changes to the operating system. Additionally, the requireAutoUpgradeSchedule policy ensures that instances are automatically updated according to a defined schedule. Together, these policies maintain system integrity and compliance with update requirements.​

Option C: Assigning AI Notebooks Runner and AI Notebooks Viewer roles controls user permissions related to running and viewing notebooks but does not directly influence operating system settings or update mechanisms.​

Option D: Implementing firewall rules to prevent SSH access limits direct access to instances but does not ensure automatic updates or prevent alterations through other means.​

Therefore, Option B is the most appropriate action, as it directly addresses both the enforcement of automatic updates and the prevention of unauthorized operating system modifications.​

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.

The problem requires restricting admin access to Google Cloud APIs based on geographic location (Canada and Germany) and environment (development and production projects).

VPC Service Controls (VPC SC): VPC Service Controls is designed to create security perimeters around Google Cloud resources and services. Its primary purpose is to prevent data exfiltration and control access to Google Cloud APIs based on the context of the request, which includes the source IP address.

Extract Reference: "VPC Service Controls provides an extra layer of security defense for Google Cloud services that is independent of Identity and Access Management (IAM). While IAM enables granular identity-based access control, VPC Service Controls enables broader context-based perimeter security, including controlling data egress across the perimeter." (Google Cloud Documentation: "Overview of VPC Service Controls" - https://cloud.google.com/vpc-service-controls/docs/overview)

Service Perimeters for Environments: Creating dedicated perimeters for development and production projects allows for logical separation of environments, which aligns with the "dedicated projects for development and production" structure.

Ingress Policies with Geographic Restrictions: VPC Service Controls uses "ingress rules" to define who and from where requests can enter a service perimeter. These ingress rules can be configured to allow access based on various attributes, including the source IP address of the request. By allowing access from specific IP ranges corresponding to Canada and Germany, you effectively restrict administrative access to APIs from those countries. You can define "access levels" (which can include IP subnets or geographical origins) and attach them to ingress policies.

Extract Reference: "To allow ingress to resources, VPC Service Controls evaluates sources and identityType attributes as an AND condition... You must specify an accessLevel or a resource (Google Cloud project or VPC network), or set accessLevel attribute to *." (Google Cloud Documentation: "Ingress and egress rules | VPC Service Controls" - https://cloud.google.com/vpc-service-controls/docs/ingress-egress-rules)

Extract Reference (for Context-Aware Access which underpins access levels): "You can create different types of Context-Aware Access policies for accessing apps: IP, device, geographic origin, and custom access-level attributes." (Google Workspace Admin Help: "Protect your business with Context-Aware Access" - https://support.google.com/a/answer/9275380) - While this references Workspace apps, the underlying mechanism of Access Context Manager (used by VPC SC) supports geographic restrictions.

Let's evaluate the other options:

A. Create dedicated firewall policies... restrict access based on geolocations: VPC firewall rules operate at the network level (Layers 3/4) within a VPC. They control traffic between VM instances or to/from the internet for network services. They do not directly control admin access to Google Cloud APIs (e.g., via the console or gcloud CLI calls) originating from outside the VPC.

B. Activate the organization policy on the folders to restrict resource location: The Resource Location Restriction organization policy constraint restricts where new resources can be created or stored (e.g., data residency requirements). It does not restrict where administrators can connect from to manage these resources or access APIs.

D. Create dedicated IAM Groups... Grant access: IAM (Identity and Access Management) controls who can access what resources and what actions they can perform. It does not natively provide control over where the access originates from (e.g., country-specific IP addresses).

Therefore, VPC Service Controls with properly configured ingress policies based on source IP/Access Levels is the recommended and most effective method for restricting admin access to Google Cloud APIs by geographic location and environment.

Create a new Service Account that should be able to list the Compute Engine instances in the project. You want to follow Google-recommended practices.

"You might have situations where you want to permanently destroy data encrypted with CMEK. To do this, you destroy the customer-managed encryption key version. You can't destroy the keyring or key, but you can destroy key versions of the key."
