ScubaGoggles

Developed by CISA, ScubaGoggles is an assessment tool that verifies a Google Workspace (GWS) organization’s configuration conforms to the policies described in the Secure Cloud Business Applications (SCuBA) Secure Configuration Baseline documents.

For the Microsoft 365 (M365) rendition of this tool, see ScubaGear.

Overview

We use a three-step process:

1. Export. In this step, we primarily use the Google Admin SDK API to export and serialize all the relevant logs and settings into json. ScubaGoggles also uses various other Google APIs to grab organization metadata, user privileges etc.
2. Verify. Compare the exported settings from the previous step with the configuration prescribed in the baselines. We do this using OPA Rego, a declarative query language for defining policy.
3. Report. Package the results as HTML and JSON.
