ScubaGear is an assessment tool that verifies that a Microsoft 365 (M365) tenant’s configuration conforms to the policies described in the Secure Cloud Business Applications (SCuBA) Security Configuration Baseline documents.
Note: This documentation can be read using GitHub Pages.
ScubaGear is for M365 administrators who want to assess their tenant environments against CISA Secure Configuration Baselines.
ScubaGear uses a three-step process:
- Step One - PowerShell code queries M365 APIs for various configuration settings.
- Step Two - It then calls Open Policy Agent (OPA) to compare these settings against Rego security policies written per the baseline documents.
- Step Three - Finally, it reports the results of the comparison as HTML, JSON, and CSV.
