To organize GCP projects based on different business units and manage IAM permissions, you should create an organization node and assign folders for each business unit. This approach allows you to logically separate projects under folders and apply IAM policies at the folder level.

Step-by-Step:

Create Organization Node: Ensure that your GCP account is linked to an organization.

Create Folders for Business Units:

Navigate to the GCP Console > IAM & Admin > Resource Manager.

Create a folder for each business unit under the organization node.

Move Projects to Folders:

Move existing projects into the respective folders according to the business unit.

Set IAM Policies:

Assign IAM roles and permissions at the folder level to manage access for each business unit independently.

Monitor and Manage: Use Cloud Audit Logs and other GCP tools to monitor the activities and ensure compliance with the organization’s policies.

The minimum length for passwords in Cloud Identity can be set to 8 characters. This aligns with common security best practices for password policies, ensuring a basic level of complexity and security.

Step-by-Step:

Access Admin Console: Log in to the Google Admin console.

Navigate to Security Settings: Go to Security > Password Management.

Set Minimum Length: Set the minimum length for passwords to 8 characters.

Save Changes: Save the settings and ensure that all user accounts adhere to the new policy.

Provision a Cloud NAT Instance:

Cloud NAT (Network Address Translation) allows instances without external IP addresses to access the internet securely.

In the Google Cloud Console, navigate to the VPC Network section and select Cloud NAT.

Create a new Cloud NAT configuration, specifying the VPC and region where your Compute Engine VMs are deployed.

Configure Cloud NAT:

Ensure that the Cloud NAT instance is configured to provide outbound internet connectivity for the VMs in your specified subnet.

This setup allows the VMs to access the internet for package updates and external installations without requiring public IP addresses.

Enable Private Google Access:

Private Google Access allows VMs in a subnet to reach Google APIs and services using internal IP addresses.

In the Google Cloud Console, navigate to the VPC Network section and select Subnets.

Edit the subnet used by your Compute Engine VMs and enable Private Google Access.

Update DevOps Scripts:

Ensure that your DevOps scripts are updated to work with the new network configuration.

Test the build process to confirm that the VMs can access necessary resources and complete the build pipeline successfully.

Billing Account Costs Manager (roles/billing.costsManager)

- Manage budgets and view and export cost information of billing accounts (but not pricing information)

Billing Account Viewer (roles/billing.viewer)

- View billing account cost information and transactions.

"To support common use cases like setting a Time to Live (TTL) for objects, retaining noncurrent versions of objects, or "downgrading" storage classes of objects to help manage costs, Cloud Storage offers the Object Lifecycle Management feature. This page describes the feature as well as the options available when using it. To learn how to enable Object Lifecycle Management, and for examples of lifecycle policies, see Managing Lifecycles." https://cloud.google.com/storage/docs/lifecycle

To prevent developers from creating user-managed service account keys and reduce the risk of key mismanagement, you should enable an organization policy that specifically prohibits the creation of these keys.

Enable an organization policy to prevent service account keys from being created (C):

Google Cloud provides the capability to enforce organizational policies that restrict various actions, including the creation of service account keys. By enabling this policy, you ensure that developers cannot create new user-managed service account keys, thus minimizing the risk of key mismanagement and potential security breaches.

To ensure that the developers can view audit logs for the development environment and the security team can review all logs, you should grant IAM roles at the appropriate resource levels:

Grant logging.admin Role to the Security Team:

Assign the logging.admin role to the security team at the organization resource level.

This grants the security team full access to all logging data across the organization, including both production and development environments.

Grant logging.viewer Role to the Developer Team:

Assign the logging.viewer role to the developer team at the folder resource level that contains all the development projects.

This restricts the developers' access to only view logs in the development environment, ensuring they do not have access to production logs.

By using these roles and assigning them at the appropriate levels, you ensure that each team has the access they need while adhering to the principle of least privilege.

Uniform bucket-level access allows you to manage permissions at the bucket level, rather than at the object level. This simplifies permission management and ensures that access to objects is controlled consistently via IAM roles, without allowing uploaders full control over the objects.

Steps:

Enable Uniform Bucket-Level Access: In the Google Cloud Console, enable uniform bucket-level access for the Cloud Storage bucket.

Configure IAM Policies: Assign appropriate IAM roles to users and groups to control access to the bucket.

Audit Logging: Enable Cloud Audit Logs to track access and modifications to the bucket.

Managing access with IAM

Cloud Bigtable is a fully managed NoSQL database service designed to handle large analytical and operational workloads. One of its key features is the ability to replicate data across multiple geographic locations automatically, ensuring high availability and resilience. Here’s a detailed explanation:

Replication: Cloud Bigtable supports multi-cluster routing and replication across different geographic regions. This means that data can be replicated across multiple zones within a region or even across regions, providing geo-redundancy.

Automatic Handling: Once configured, Bigtable automatically manages replication without requiring manual intervention. This is in line with the company's policy for long-term data storage that necessitates automatic replication over at least two geographic places.

Use Case Suitability: Bigtable is ideal for applications that require low-latency access to large amounts of data, which makes it suitable for various use cases including analytical applications, IoT, and financial data processing.

Configuration: Setting up replication involves creating instances in multiple zones and configuring them to replicate data. Google Cloud’s management interface and APIs make this straightforward to configure and monitor.
