ScubaGoggles

GWS Secure Configuration Baseline Assessment Tool

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.

Warning

This tool is in an alpha state and in active development. At this time, outputs could be incorrect and should be reviewed carefully.

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.

Limitations of the tool

The majority of the conformance checks done by ScubaGoggles rely on GWS Admin log events. If there is no log event corresponding to a SCuBA baseline policy, ScubaGoggles will indicate that the setting currently can not be checked on its HTML report output. In this situation, we recommend you manually review your GWS security configurations with the SCuBA security baselines. See Limitations for more details.
