Professional-Cloud-Security-Engineer Exam Dumps - Google Cloud Certified - Professional Cloud Security Engineer

Objective: Store and retrieve sensitive configuration data for an application running on Compute Engine.

Solution: Use Secret Manager to securely store and manage access to sensitive configuration data.

Steps:

Step 1: Open the Google Cloud Console.

Step 2: Navigate to the Secret Manager section.

Step 3: Create a new secret and add the sensitive configuration data.

Step 4: Set appropriate IAM policies to control access to the secret.

Step 5: Update the application to retrieve the secret from Secret Manager using the appropriate client libraries or APIs.

Secret Manager provides a secure and centralized way to manage sensitive information, with fine-grained access control and audit logging capabilities.

Storing and Accessing Secrets

Set the Resource Location Restriction organization policy constraint at the Folder level:

Setting the constraint at the folder level allows for very granular control over data residency requirements.

Each folder can represent a specific geographical location, and projects within those folders will inherit the location constraint, ensuring compliance with regulatory requirements.

This approach provides flexibility to manage data residency across different regions within the same organization.

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.

Session Management Best Practices

Setting up a Shared VPC allows you to create a centrally managed network that spans multiple projects. Here's how you can achieve this while ensuring separation of duties:

Create a Host Project:

Create a project that will act as the host project for your Shared VPC.

Configure Shared VPC:

In the host project, enable the Shared VPC feature.

Create Service Projects:

Create separate service projects for different teams, such as developers and other stakeholders.

Assign Roles:

Security Team: Grant the Compute Network Admin role. This allows the security team to manage network resources, such as firewall rules, subnets, and routes.

Developers: Share the host project’s network with the service projects. Assign roles like Compute Instance Admin to developers in the service projects, enabling them to create and manage VM instances without altering network configurations.

Firewall Management:

The security team will define and manage firewall rules within the host project, ensuring consistent and secure network policies.

Benefits:

Separation of Duties: Security teams handle networking, and developers focus on application deployment and management.

Centralized Control: Network policies are centrally managed, ensuring compliance and security.

Scalability: Easy to add new projects and teams without compromising the overall network security.

Managing Resources with Shared VPC

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.

Using OAuth 2.0 for Server to Server Applications

Objective: Create a Service Account that can list Compute Engine instances in the project following Google-recommended practices.

Solution: Create a custom role and assign it to the Service Account.

Steps:

Step 1: Open the Google Cloud Console.

Step 2: Navigate to the IAM & Admin page and select "Roles".

Step 3: Click on "Create Role" and define a new role with a suitable name and description.

Step 4: Add the permission compute.instances.list to the custom role.

Step 5: Save the custom role.

Step 6: Go to the "Service Accounts" section.

Step 7: Create a new Service Account or select an existing one.

Step 8: Assign the newly created custom role to the Service Account.

By creating a custom role with the specific permission to list Compute Engine instances, you follow the principle of least privilege, which is a recommended security practice.

Best Practices for IAM

Objective: Ensure private communication between application tiers in different GCP Organizations.

Solution: Use VPC peering to enable private communication without traversing the public internet.

Steps:

Step 1: Open the Google Cloud Console.

Step 2: Navigate to the VPC Network Peering page.

Step 3: Create a new VPC peering connection in the project hosting the application tier.

Step 4: Specify the VPC network in the other organization (hosting the storage tier) to peer with.

Step 5: Accept the peering request in the other project.

Step 6: Configure the necessary routes and firewall rules to allow traffic between the peered VPC networks.

VPC peering allows you to connect two VPC networks privately and directly, ensuring that traffic between them does not traverse the public internet.

VPC Network Peering Guide

Objective: Ensure that the analytics workload on Compute Engine instances accessing Cloud Storage does not interact with the public internet.

Solution:

Private Google Access: This allows Compute Engine instances that only have internal IP addresses to reach Google APIs and services through a private connection without the need for a public IP address.

No Public IP Addresses: By avoiding public IP addresses for the instances, you ensure that they are not accessible from the internet and do not initiate internet connections.

Steps:

Step 1: Open the Google Cloud Console.

Step 2: Navigate to the VPC Network page and select the subnet where the Compute Engine instances are located.

Step 3: Enable Private Google Access for the subnet.

Step 4: Ensure that when launching the Compute Engine instances, no public IP addresses are assigned to them.
