Microsoft Intune administrators often struggle with managing Role-Based Access Control (RBAC) configurations. Ugur Koc has released IntuneRBAC, an open-source PowerShell tool that generates a detailed HTML report to visualize and analyze your Intune RBAC setup.

Key Features:

  • Complete overview of all roles and scope tags
  • Highlights unused roles and overlapping permissions
  • Visual relationship diagram for better understanding
  • Detailed permission breakdowns per role

How to Use IntuneRBAC:

1. Install PowerShell 7 (if not already installed).

2. Run the following commands:

Install-Script -Name IntuneRBAC
IntuneRBAC

3. The tool generates an HTML report for easy analysis.

Essential PowerShell Commands for Intune Admins

Here are some useful PowerShell commands for managing Intune RBAC:

1. List All Intune Roles

Get-MgDeviceManagementRoleDefinition

2. Get Role Assignments

Get-MgDeviceManagementRoleAssignment

3. Check Unused Roles

$allRoles = Get-MgDeviceManagementRoleDefinition 
$assignedRoles = Get-MgDeviceManagementRoleAssignment | Select -ExpandProperty RoleDefinitionId 
$unusedRoles = $allRoles | Where-Object { $_.Id -notin $assignedRoles } 
$unusedRoles | Format-Table DisplayName, Description

4. Export RBAC Config to CSV

Get-MgDeviceManagementRoleAssignment | Export-Csv -Path "Intune_RBAC_Assignments.csv" -NoTypeInformation

5. Check Overlapping Permissions

 Compare two roles for permission overlaps 
$role1 = Get-MgDeviceManagementRoleDefinition -RoleDefinitionId "Role1_ID" 
$role2 = Get-MgDeviceManagementRoleDefinition -RoleDefinitionId "Role2_ID" 
Compare-Object $role1.RolePermissions $role2.RolePermissions -Property ResourceActions -IncludeEqual

Linux Equivalent (Azure CLI)

If you’re managing Intune from a Linux system, use Azure CLI: 

az account set --subscription "Your_Sub_ID" 
az rest --method get --url "https://graph.microsoft.com/v1.0/deviceManagement/roleDefinitions"

What Undercode Say

Managing RBAC in Intune is critical for security and operational efficiency. Tools like IntuneRBAC simplify auditing and optimizing permissions. Always:
– Audit roles regularly to remove unused permissions.
– Follow least privilege to minimize risks.
– Automate reports with PowerShell for continuous monitoring.

For advanced automation, integrate with Microsoft Graph API for dynamic role management.

Expected Output:

A clean HTML report displaying:

  • Role assignments
  • Unused roles
  • Permission overlaps
  • Visual RBAC diagram

Use this tool to strengthen your Intune security posture and ensure compliance.
