ScubaGear – Ensuring Microsoft 365 Security Compliance

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.

Target Audience

ScubaGear is for M365 administrators who want to assess their tenant environments against CISA Secure Configuration Baselines.

Overview

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.

Getting Started

To install ScubaGear from PSGallery, open a PowerShell 5 terminal on a Windows computer and install the module:

# Install ScubaGear
Install-Module -Name ScubaGear

To install its dependencies:

# Install the minimum required dependencies
Initialize-SCuBA 

To verify that it is installed:

# Check the version
Invoke-SCuBA -Version

To run ScubaGear:

# Assess all products
Invoke-SCuBA -ProductNames *
