The Organization Policy Service provides a specific constraint called constraints/gcp.restrictServiceUsage. This is the most direct and efficient way to "Allow" or "Deny" specific Google Cloud APIs (services) at any node in the hierarchy (Org, Folder, or Project).

According to Google Cloud Documentation (Restricting Resource Service Usage):

"The Restrict Resource Service Usage constraint allows enterprise administrators to control which Google Cloud services can be used within their Google Cloud resource hierarchy. This constraint can be enforced on an Organization, Folder, or Project. When applied at the folder level, it restricts service usage for all descendant projects within that folder."

Why Option C is the most efficient:

Targeted: By applying it directly to the folder, you don't need to manage complex "exceptions" at the Org level (as in Option B).

Simple: It is a single policy rule that defines an "Allowlist" of services.

IAM vs. Org Policy: IAM (Option A) controls who can do something, but Org Policy controls what can be done. Even if a user is an Editor, the Org Policy will block them from enabling a restricted API.

VPC-SC (Option D): VPC Service Controls is much more complex and is used for data exfiltration prevention, not for simply restricting which APIs can be enabled/used in a project.

To maintain a historical record of what was running in Google Cloud Platform at any point in time, you should use Forseti Security to automate inventory snapshots. Forseti Security is an open-source toolkit that helps to automate security and compliance in GCP by taking inventory snapshots of GCP resources.

Step-by-Step:

Install Forseti Security:

Follow the installation guide to deploy Forseti Security on your GCP environment.

Configure Inventory:

Set up the inventory module in Forseti to capture and store snapshots of GCP resources.

Schedule Snapshots:

Use Forseti’s configuration to schedule regular inventory snapshots.

Access Historical Data:

Review and access historical records through Forseti’s dashboard or by querying the Forseti database.

Compliance and Monitoring: Use Forseti to ensure compliance and monitor changes over time.

Generate Supply Chain Levels for Software Artifacts (SLSA) level 3 assurance by using Cloud Build: SLSA is a framework for ensuring the integrity of software artifacts. By using Cloud Build, you can automate the build process and generate SLSA level 3 compliance, which includes verifiable build steps and provenance.

View the build provenance in the Security insights side panel within the Google Cloud console: The build provenance provides a detailed history of how the software was built, including the source code, build process, and any dependencies. This information is accessible through the Security insights side panel in the Google Cloud console, allowing you to verify the integrity and authenticity of your software artifacts.
