Easy to use PowerShell script to enumerate access permissions in an Azure Active Directory environment.

Background details can be found in the accompanied blog posts:

• Untangling Azure Active Directory Principals & Access Permissions
• Untangling Azure Active Directory Permissions II: Privileged Access

Requirements

To run this script you'll need these two PowerShell modules:

• Microsoft.Graph
• AADInternals
• AzureADPreview

All of these can be installed directly within PowerShell:

PS:> Install-Module Microsoft.Graph
PS:> Install-Module AADInternals
PS:> Install-Module AzureADPreview

Usage

First time use

The script uses a browser-based Login UI to connect to Azure. If you run the tool for the first time you might experience the following error

[*] Connecting to Microsoft Graph...
WARNING: WebBrowser control emulation not set for PowerShell or PowerShell ISE!
Would you like set the emulation to IE 11? Otherwise the login form may not work! (Y/N): Y
Emulation set. Restart PowerShell/ISE!

To solve this simply allow PowerShell to emulate the browser and rerun your command.

Example use

Import and run, no argumentes needed.

Note: On your first run you will likely have to authenticate twice (once Microsoft Graph and once against Azure AD Graph). I might wrap this into a single login in the future...

PS:> Import-Module .\Azure-AccessPermissions.ps1
