Objective: Reduce the risk of Google Cloud user accounts being compromised.

Solution: Implement strong password policies and post-SSO 2-Step Verification using security keys.

Steps:

Step 1: In Active Directory, configure a domain password policy with strong settings (e.g., complexity, length, expiration).

Step 2: In the Google Admin console, navigate to the Security settings.

Step 3: Enable 2-Step Verification and configure it to use security keys for post-SSO verification.

Step 4: Ensure all users enroll in the 2-Step Verification with security keys.

Using strong password policies in Active Directory along with security keys for 2-Step Verification post-SSO provides enhanced security against account compromises.

Objective: You want to limit the images that can be used as the source for boot disks to a set of images stored in a dedicated project.

Solution: Use the Organization Policy Service.

Steps:

Step 1: Open the Google Cloud Console.

Step 2: Navigate to the Organization Policies page.

Step 3: Create a new policy by clicking on "Create Policy".

Step 4: Select the constraint compute.trustedimageProjects.

Step 5: Set the policy to ALLOW and specify the project ID where the trusted images are stored in the whitelist.

Step 6: Save and apply the policy.

By creating a compute.trustedimageProjects constraint at the organization level and specifying the trusted project in the allow list, you ensure that only images from this project can be used for boot disks across the organization.

Google Cloud Storage provides an Object Lifecycle Management feature that can help automate data retention and deletion processes, ensuring compliance with data privacy regulations while minimizing storage costs.

Lifecycle Management: Object Lifecycle Management allows you to define rules that automatically delete objects after a specific period. This ensures that data is only retained for the required amount of time and is deleted once it expires.

Configuration: You can configure lifecycle rules to delete objects based on conditions such as the age of the object, the creation date, or custom metadata. This allows for precise control over the retention period of your data.

Cost Efficiency: By using lifecycle policies to delete data automatically, you can reduce storage costs, as you only pay for the storage you actively use.
