Best and Fastest way to implement Device-Based Conditional Access Policies in AzureAD. No compliance required !

Up to a few weeks ago, we needed to fully enroll the devices in Microsoft Endpoint Manager #MEM (a.k.a. Intune) to be able to use device-based conditional access policies. Similarly, we needed to evaluate the compliance of the device which was not the most reliable technology. However, this new feature allows to easily evaluate these conditions based on the type of registration of the device. Therefore, fully enrolling the devices in Intune is not required anymore. As long as the device has been integrated with AzureAD, we can create conditional access policies. The properties filter we can use are as the following:

  1. AzureAD Joined
  2. Hybrid Azure AD Joined
  3. Azure AD registered

What is a trustType attribute: It is a valid registered state for devices. Supported values are: AzureAD (used for Azure AD joined devices), ServerAD (used for Hybrid Azure AD joined devices), Workplace (used for Azure AD registered devices)              

This is a great feature and adds a lot of value to the implementation. In my case, I currently have a customer on a highly secured industry that is evaluating Office365 and requires to limit access to only corporate-owned Win10 devices, but it is not implementing Endpoint Management nor is interested in enrolling the devices to evaluate compliancy. By synchronizing the devices using AzureAD Connect and automatically joining the devices as Hybrid AzureAD we can accomplish their specific requirement.

Please note that Device state and filters for devices cannot be used together in Conditional Access policy.

Hope you like this policy as much as I do.

Until next time !

Fastest way to capture and upload the hardware hashes into Intune AutoPilot (Microsoft Device Management #MEM)

We expect the vendors to provide the Windows Autopilot hardware hashes or onboard the devices directly into our tenant. However, that is not usually the case. While the process has improved over the years, there are situation where vendors may not be able to generate the hardware hashes on a timely manner, or not at all. That is why Windows Autopilot device registration can be done within your organization by manually collecting the hardware hashes and uploading this information in a comma-separated-value (CSV) file.

STOP THERE… that process has been updated and improved, making our life much easier. Thank to a newly available option as part of the Windows10 devices, you can manually generate the hashes and automatically upload the hashes to your tenant without the need exporting it into a .CSV file.

During the OOBE (Out of the Box Experience) you also can initiate the hardware hash upload by launching a command prompt (Shift+F10 at the sign in prompt), and using the following commands.

Prerequisite: Your device needs to be connected either a wired or wireless network with internet access.

Powershell.exe 
Install-Script -name Get-WindowsAutopilotInfo -Force
Set-ExecutionPolicy Unrestricted
Get-WindowsAutoPilotInfo -Online

At this point you will be prompted to sign in, an account with the Intune Administrator role is sufficient, and the device hash will then be uploaded automatically. If MFA is enabled, you will be required to use it. (Always make sure to have MFA enabled in all your accounts)

Upon confirmation of the uploaded device hash details, run a sync in the Microsoft Endpoint Manager Admin Center and wait for your new device to appear.

Once the device is shown in your device list, and an autopilot profile is assigned, restarting the device will result in OOBE running through Windows Autopilot provisioning process.

Azure Application Proxy for RDS (Finally fully supported)

This is a continuation of one of my past blogs. Finally this came out, and I am excited about this announcement. The new Azure Application Proxy for RDS permits the clients to use App Proxy with RDS to reduce the attack surface of the RDS deployment by enforcing pre-authentication and Conditional Access policies like requiring Multi-Factor Authentication (MFA) or using a compliant device before users can access RDS, if using conditional access. App Proxy also doesn’t require to open inbound connections through your firewall, Yeah!!!.

To use the RDS web client with App Proxy, first you need to upgrade to App Proxy version, 1.5.1975.0. If you haven’t already, you will need to configure RDS to work with App Proxy. App Proxy will handle the internet facing component of your RDS deployment and protect all traffic with pre-authentication and any Conditional Access policies in place. For steps on how to do this, see my previous blog.
