Intune compliance with Lenovo dynamic BIOS configuration

Introduction

Using compliance policies in Intune is a great idea for many reasons. Main reason is to be able to set certain security standards before granting your users’ access to company resources.

Letting your users deal with setup configurations in BIOS might be to much of a task to be asking, so this blog post will show how we can regulate device BIOS configurations with a dynamic configuration stored in the cloud.

 

Requirements

• Microsoft Endpoint Manager
• Lenovo device
• GitHub

 

Setup BIOS script and configuration

We need to know the configuration available for the system.

Start an elevated PowerShell Prompt

(Get-WmiObject -Class Lenovo_BiosSetting -Namespace root\wmi).CurrentSetting | Where-Object {$_ -ne ""} | Sort-Object

 

Here we see the parameter we need to use for configuring SecureBoot. Copy that.

 

Go to GitHub (if you don’t have one already start creating one, or use another storage type that can host your csv.)

Add file

Create new files

 

Give it a name

 

Add these values to it (you can add as many you like, to configure on your device)

 

Setting,Value; SecureBoot,Enable;

   

Commit changes

 

Click on the CSV file

 

Click RAW

 

Copy the URL

 

Download this script

Paste your link into the script

Save it locally.

 

Go to Endpoint Manager https://endpoint.microsoft.com/

 

Go to Endpoint analytics

 

Proactive remediations

 

Create script package

 

Give it a name

 

Insert detection script and Remediation script.

Detection script can be downloaded here

Remediation script is the one you where you added the URL.

 

Click next

 

Select groups to include

Choose a test group with few clients and work your way toward full production.

My flow will run every day.

Create

 

Now sit back and relax enjoy a cup of coffee and see your remediation data stream into Endpoint Manager.

 

On the client a local log is placed for the Intune diagnostics collector to collect if you need to debug

 

Next time compliance check happens

 

Summary

Compliance settings is great once you found out how to use them correctly. They can be somewhat difficult, as some use cases are difficult to cover.

Hope this post helped you to see the benefit of configuring your setup as dynamic as possible for you to easily add new changes without to much effort.

Happy testing!
