“Ideally you will have separate computers for work and personal use; this will offer a different type of protection” – Unites States Computer emergency Team.

In this post we’ll configure Windows Information Protection with enrollment for devices managed with Intune. If you’ve configured automatic MDM enrollment for Windows 10, then all devices for users in the MDM user scope will automatically enroll in MDM. Therefore the Windows Information Protection with enrollment (WIP-MDM) policy will apply. In a previous post I wrote about configuring Intune MDM User Scope and MAM User Scope for Windows 10. It contains lots of relevant information so have a look at it.

For many organizations, data is something we take for granted as being safe, stored somewhere in the cloud or on-site servers hidden in a broom closet. A common misconception is that only the big organizations, governments, and businesses get targeted by cyber criminals. That’s just not true.

“There are only two types of companies: those that have been hacked, and those that will be.” Robert Mueller FBI Director, 2012

No matter what kind of data you’re storing in the cloud or on-site, data protection should be one of your biggest priorities.

Prerequisites

Make sure you have all the prerequisites in place;

• Intune enabled as the MDM authority
• Windows 10 1703 and above (Pro, Enterprise, Education)
• EMS E3 licenses (or at the very least Intune and Azure AD premium P1)

Configuring your MDM user scope

Although it’s not a requirement, I recommend setting up Windows 10 automatic enrollment by configuring your MDM user scope in Azure AD. I dedicated another blog post on configuring MDM users scope and MAM user scope. If you need to know more about configuring these scopes make sure to read that post before you continue.

Creating a WIP Protection Policy

• Sign in to the Azure portal and Choose All Services > Intune.
• Select Client apps > App protection policies
• Click on Create policy to create your Windows Information Protection with enrollment policy

• Give the policy a name and a description. Choose Windows 10 as the platform from the drop-down menu.
• Finally select the Enrollment state. In this case we are creating a WIP policy for MDM managed devices, so select “with enrollment”

Adding apps to your WIP Policy

Let’s continue and select apps you want to allow or deny access to your corporate data. There are two kinds of applications you need to know about; Enlightened applications (MAM aware)and Unenlightened (MAM Unaware) applications. The difference is that enlightened apps can differentiate between corporate and personal data whereas unenlightened apps cannot. Read my previous post about WIP Basics to fully understand the solution. Also read the Microsoft blog for more information about configuring WIP policies and adding apps to your WIP policy.

When you are ready to continue, click on Protected apps and then click on Add apps

• On the Add apps blade choose Recommended apps from the drop-down menu.
• Click on the select box next to NAME (See the arrow below). This will select all the recommended applications in the list.
• When you add applications to your protected apps list, they are setup as allowed by default. Make changes here before you continue
• click on OK at the bottom of the page.

The Action column shows which applications are allowed or denied access.

• On the protected apps blade, click on OK at the bottom of the page.

Note: There is no need to add all of the Office 365 Pro Plus suite applications manually to this list. Read more here. 

Microsoft helps by adding the “Office-365-ProPlus-1810-Allowed.xml” applocker file when you add recommended apps. Download the XML file from the above link, to have a look at the code if you like.

• Back on the Create policy blade, click on Configure required settings

Configure required settings

For the required settings you will need to set the protection mode, and your corporate identity.

Windows Information Protection Modes

For the remainder of this post I will assume you have set the Windows Information Protection mode to Allow Overrides. Have a look at the Microsoft documentation for a complete description of all modes.

• Block: Blocks enterprise data from leaving protected apps
• Allow overrides: User is prompted when attempting to relocate data from a protected to a non-protected app.
• Silent: User is free to relocate data off of protected apps.
• Off: User is free to relocate data off of protected apps.

Note: The Off mode is not recommended. It’s best to start with Silent and from there update to Allow Override or Block.

• Select Allow Overrides and continue with setting your corporate identity

The corporate identity field should contain only your primary domain. Add additional domains as ‘Protected domains’ under the ‘Network perimeter’ in the ‘Advanced settings’ tab. The corporate identity field is auto-defined so check it and if it’s not correct, change it and click on Save to close the Required Settings blade.

WIP Learning Mode

When you first start with Windows Information Protection and don’t know if the recommended apps will be enough, consider starting with the Protection Mode set to Silent.

WIP Learning mode essentially monitors all applications that access corporate data. Because in silent mode WIP will not block any action but will log inappropriate data sharing, giving you the opportunity to monitor your WIP enabled apps but also apps you did not add to your WIP policy.

I will write about setting up and configuring WIP Learning Mode if you want to explore that path first, but that is for another post. It will explain how to setup Device Health and where to find the WIP learning app reports you can use to fine-tune your WIP policies.

Windows Information Protection Network boundary

Corporate cloud resources are identified by configuring WIP network boundaries and help protect corporate data by encrypting data that is downloaded from there to devices. In the next section you will add your network boundaries. The Cloud resource SharePoint is added by default. 

Have a look at the table below to get you started or check out the Microsoft documentation.

After adding your Cloud Resources the configuration should look like this: 

Note: Have a look at this /*AppCompat*/ notification:

When I started testing I missed this notification and later found that I could not use browsers like Chrome or FireFox. They would simply not load any internet page. I could use 3^rd party browsers after adding /*AppCompat*/ to my cloud resources.

When an unenlightened app tries to connect to a cloud resource through an IP and Windows can’t determine whether to allow the app to connect, it will automatically block the connection. Read thisMicrosoft document a few times and you will understand Here is a another important piece of information from the Microsoft blog post:

Note: I’ll write another post about troubleshooting WIP. There are some important limitations and considerations you need to be aware of when configuring the Network boundaries. I’ve found some undocumented domains you might want to add to your Cloud Resources list to make WIP even more secure, but for now suggest you start with a pilot and test everything you can, before you deploy WIP company wide.

Other settings to configure on the advanced settings blade

Data Protection

The tool-tips tells us and I quote;

“A recovery certificate is a special Encrypting File System (EFS) certificate you can use to recover encrypted files if your encryption key is lost or damaged. You need to create the recovery certificate, and specify it here. More information is here “

Using a DRA certificate isn’t mandatory. However, Microsoft strongly recommends using it.

Set up Azure Rights Management with WIP

WIP can integrate with Microsoft Azure Rights Management to enable secure sharing of files when users want to use removable drives such as USB drives. For this to work , you must already have Azure Rights Management set up. This feature works great and enables your users to share files among each other by encrypting files that are saved to USB with Azure Rights Management (Azure RMS). Azure RMS is the protection technology used by Azure Information Protection (AIP)

For now you will have to do with the official Microsoft documentation but I will be writing another dedicated blog post in this series on setting up and configuring Azure Rights Management with WIP.

• On the Advanced settings blade, click on OK at the bottom of the page.
• Back on the Create Policy blade, click on Create to wrap it up

Piloting and deploying WIP

Deploy your newly create WIP policy to a pilot group of users.

Once you’ve deployed a WIP policy, they will be applied the next time devices sync with Intune. Depending on you configuration the user experience can be different. Assuming you’ve set your protection mode to “Allow overrides” users will get notified when the mix corporate and private workspace and data. This protection mode will also audit when users change file ownership from corporate to private.

I will write another dedicated blog posts in this series on user experience with WIP and monitoring. Come back again or follow me on twitter to get notified.

Monitoring Deployment status

When you are piloting WIP policies, you’ll most likely have test devices at hand where you can immediately see the effect of your policies, once the device is in sync with Microsoft Intune. You can also monitor and report about your policies and their deployment status from Azure.

• Sign in to the Azure portal and Choose All Services > Intune.
• Select Client apps > App protection status
• Download the report you want
  • App Protection Report: WIP via MDM

The reports contain information about the user and device name but also the App Protection Policy that applied to the user. The example below shows testuser6 has 2 BYO devices where data is managed and protected with the “WIP Without Enrollment” policy.

Conclusion

Windows Information Protection with enrollment provides a robust solution by protecting work data that is downloaded to Windows 10 devices. It works by separating personal and work data, thus helping prevent unintentional information sharing. Combined with AIP it adds an extra layer of security making it possible for your users to share data amongst each other. For example on a USB drive.

As with other methods used to protect information and devices, you need to find a good balance between security and business productivity. If users really set their mind on stealing information, they will find a way to do so, no matter what you do. Lucky for us admins, most users don’t have malicious intent.

Please check the official Microsoft documentation as they are very complete and probably will update their documentation more frequently. Most importantly, this post (and any other) is based on my own experiences in the field deploying and configuring Microsoft solutions.I hope you have found this blog interesting and of added value considering there are so many other bloggers writing about Microsoft solutions. If you have any feedback I would appreciate it if you would write a line or two.
