Create a Windows Information Protection policy in Microsoft Intune

  • Artigo

Note

Starting in July 2022, Microsoft is deprecating Windows Information Protection (WIP). Microsoft will continue to support WIP on supported versions of Windows. New versions of Windows won't include new capabilities for WIP, and it won't be supported in future versions of Windows. For more information, see Announcing sunset of Windows Information Protection.

For your data protection needs, Microsoft recommends that you use Microsoft Purview Information Protection and Microsoft Purview Data Loss Prevention. Purview simplifies the configuration set-up and provides an advanced set of capabilities.

Applies to:

  • Windows 10
  • Windows 11

Microsoft Intune has an easy way to create and deploy a Windows Information Protection (WIP) policy. You can choose which apps to protect, the level of protection, and how to find enterprise data on the network. The devices can be fully managed by Mobile Device Management (MDM), or managed by Mobile Application Management (MAM), where Intune manages only the apps on a user's personal device.

Differences between MDM and MAM for WIP

You can create an app protection policy in Intune either with device enrollment for MDM or without device enrollment for MAM. The process to create either policy is similar, but there are important differences:

  • MAM has more Access settings for Windows Hello for Business.
  • MAM can selectively wipe company data from a user's personal device.
  • MAM requires an Microsoft Entra ID P1 or P2 license.
  • A Microsoft Entra ID P1 or P2 license is also required for WIP auto-recovery, where a device can re-enroll and regain access to protected data. WIP auto-recovery depends on Microsoft Entra registration to back up the encryption keys, which requires device auto-enrollment with MDM.
  • MAM supports only one user per device.
  • MAM can only manage enlightened apps.
  • Only MDM can use BitLocker CSP policies.
  • If the same user and device are targeted for both MDM and MAM, the MDM policy will be applied to devices joined to Microsoft Entra ID. For personal devices that are workplace-joined (that is, added by using Settings > Email & accounts > Add a work or school account), the MAM-only policy will be preferred but it's possible to upgrade the device management to MDM in Settings. Windows Home edition only supports WIP for MAM-only; upgrading to MDM policy on Home edition will revoke WIP-protected data access.

Prerequisites

Before you can create a WIP policy using Intune, you need to configure an MDM or MAM provider in Microsoft Entra ID. MAM requires an Microsoft Entra ID P1 or P2 license. A Microsoft Entra ID P1 or P2 license is also required for WIP auto-recovery, where a device can re-enroll and regain access to protected data. WIP auto-recovery relies on Microsoft Entra registration to back up the encryption keys, which requires device auto-enrollment with MDM.

Configure the MDM or MAM provider

  1. Sign in to the Azure portal.

  2. Select Microsoft Entra ID > Mobility (MDM and MAM) > Microsoft Intune.

  3. Select Restore Default URLs or enter the settings for MDM or MAM user scope and select Save:

    Configure MDM or MAM provider.

Create a WIP policy

  1. Sign in to the Microsoft Intune admin center.

  2. Open Microsoft Intune and select Apps > App protection policies > Create policy.

    Open Client apps.

  3. In the App policy screen, select Add a policy, and then fill out the fields:

    • Name. Type a name (required) for your new policy.

    • Description. Type an optional description.

    • Platform. Choose Windows 10.

    • Enrollment state. Choose Without enrollment for MAM or With enrollment for MDM.

    Add a mobile app policy.

  4. Select Protected apps and then select Add apps.

    Add protected apps.

    You can add these types of apps:

Note

An application might return access denied errors after removing it from the list of protected apps. Rather than remove it from the list, uninstall and reinstall the application or exempt it from WIP policy.

Select Recommended apps and select each app you want to access your enterprise data or select them all, and select OK.

Microsoft Intune management console: Recommended apps.

Add Store apps

Select Store apps, type the app product name and publisher, and select OK. For example, to add the Power BI Mobile App from the Store, type the following:

  • Name: Microsoft Power BI
  • Publisher: CN=Microsoft Corporation, O=Microsoft Corporation, L=Redmond, S=Washington, C=US
  • Product Name: Microsoft.MicrosoftPowerBIForWindows

Add Store app.

To add multiple Store apps, select the ellipsis ….

If you don't know the Store app publisher or product name, you can find them by following these steps.

  1. Go to the Microsoft Store for Business website, and find your app. For example, Power BI Mobile App.

  2. Copy the ID value from the app URL. For example, the Power BI Mobile App ID URL is https://www.microsoft.com/store/p/microsoft-power-bi/9nblgggzlxn1, and you'd copy the ID value, 9nblgggzlxn1.

  3. In a browser, run the Store for Business portal web API, to return a JavaScript Object Notation (JSON) file that includes the publisher and product name values. For example, run https://bspmts.mp.microsoft.com/v1/public/catalog/Retail/Products/9nblgggzlxn1/applockerdata, where 9nblgggzlxn1 is replaced with your ID value.

    The API runs and opens a text editor with the app details.

     {
 	"packageIdentityName": "Microsoft.MicrosoftPowerBIForWindows",
 	"publisherCertificateName": "CN=Microsoft Corporation, O=Microsoft Corporation, L=Redmond, S=Washington, C=US"
 }

  4. Copy the publisherCertificateName value into the Publisher box and copy the packageIdentityName value into the Name box of Intune.

    Important

    The JSON file might also return a windowsPhoneLegacyId value for both the Publisher Name and Product Name boxes. This means that you have an app that's using a XAP package and that you must set the Product Name as windowsPhoneLegacyId, and set the Publisher Name as CN= followed by the windowsPhoneLegacyId.

    For example:

    {
    "windowsPhoneLegacyId": "ca05b3ab-f157-450c-8c49-a1f127f5e71d",
}

Add Desktop apps

To add Desktop apps, complete the following fields, based on what results you want returned.

Field Manages
All fields marked as * All files signed by any publisher. (Not recommended and may not work)
Publisher only If you only fill out this field, you'll get all files signed by the named publisher. This might be useful if your company is the publisher and signer of internal line-of-business apps.
Publisher and Name only If you only fill out these fields, you'll get all files for the specified product, signed by the named publisher.
Publisher, Name, and File only If you only fill out these fields, you'll get any version of the named file or package for the specified product, signed by the named publisher.
Publisher, Name, File, and Min version only If you only fill out these fields, you'll get the specified version or newer releases of the named file or package for the specified product, signed by the named publisher. This option is recommended for enlightened apps that weren't previously enlightened.
Publisher, Name, File, and Max version only If you only fill out these fields, you'll get the specified version or older releases of the named file or package for the specified product, signed by the named publisher.
All fields completed If you fill out all fields, you'll get the specified version of the named file or package for the specified product, signed by the named publisher.

To add another Desktop app, select the ellipsis …. After you've entered the info into the fields, select OK.

Microsoft Intune management console: Adding Desktop app info.

If you're unsure about what to include for the publisher, you can run this PowerShell command:

Get-AppLockerFileInformation -Path "<path_of_the_exe>"

Where "<path_of_the_exe>" goes to the location of the app on the device. For example:

Get-AppLockerFileInformation -Path "C:\Program Files\Windows NT\Accessories\wordpad.exe"

In this example, you'd get the following info:

Path                   Publisher
----                   ---------
%PROGRAMFILES%\WINDOWS NT\ACCESSORIES\WORDPAD.EXE O=MICROSOFT CORPORATION, L=REDMOND, S=WASHINGTON, C=US

Where O=MICROSOFT CORPORATION, L=REDMOND, S=WASHINGTON, C=US is the Publisher name and WORDPAD.EXE is the File name.

Regarding to how to get the Product Name for the Apps you wish to Add, contact the Windows Support Team to request the guidelines

Import a list of apps

This section covers two examples of using an AppLocker XML file to the Protected apps list. You'll use this option if you want to add multiple apps at the same time.

For more info about AppLocker, see the AppLocker content.

</AppLockerPolicy>

  13. After you've created your XML file, you need to import it by using Microsoft Intune.

Create an Executable rule for unsigned apps

The executable rule helps to create an AppLocker rule to sign any unsigned apps. It enables adding the file path or the app publisher contained in the file's digital signature needed for the WIP policy to be applied.

  1. Open the Local Security Policy snap-in (SecPol.msc).

  2. In the left pane, select Application Control Policies > AppLocker > Executable Rules.

  3. Right-click Executable Rules > Create New Rule.

    Local security snap-in, showing the Executable Rules.

  6. On the Conditions page, select Path and then select Next.

    Screenshot with Path conditions selected in the Create Executable Rules wizard.

  7. Select Browse Folders... and select the path for the unsigned apps. For this example, we're using "C:\Program Files".

    Screenshot of the Path field of the Create Executable Rules wizard.

  8. On the Exceptions page, add any exceptions and then select Next.

  9. On the Name page, type a name and description for the rule and then select Create.

  10. In the left pane, right-click AppLocker > Export policy.

  11. In the Export policy box, browse to where the policy should be stored, give the policy a name, and then select Save.

    The policy is saved and you'll see a message that says one rule was exported from the policy.

  12. After you've created your XML file, you need to import it by using Microsoft Intune.

To import a list of protected apps using Microsoft Intune

  1. In Protected apps, select Import apps.

    Import protected apps.

    Then import your file.

    Microsoft Intune, Importing your AppLocker policy file using Intune.

  2. Browse to your exported AppLocker policy file, and then select Open.

    The file imports and the apps are added to your Protected apps list.

Exempt apps from a WIP policy

If your app is incompatible with WIP, but still needs to be used with enterprise data, then you can exempt the app from the WIP restrictions. This means that your apps won't include auto-encryption or tagging and won't honor your network restrictions. It also means that your exempted apps might leak.

  1. In Client apps - App protection policies, select Exempt apps.

    Exempt apps.

  2. In Exempt apps, select Add apps.

    When you exempt apps, they're allowed to bypass the WIP restrictions and access your corporate data.

  3. Fill out the rest of the app info, based on the type of app you're adding:

  4. Select OK.

Manage the WIP protection mode for your enterprise data

After you've added the apps you want to protect with WIP, you'll need to apply a management and protection mode.

We recommend that you start with Silent or Allow Overrides while verifying with a small group that you have the right apps on your protected apps list. After you're done, you can change to your final enforcement policy, Block.

  1. From App protection policy, select the name of your policy, and then select Required settings.

    Microsoft Intune, Required settings shows Windows Information Protection mode.

    Mode Description
    Block WIP looks for inappropriate data sharing practices and stops the employee from completing the action. This can include sharing info across non-enterprise-protected apps in addition to sharing enterprise data between other people and devices outside of your enterprise.
    Allow Overrides WIP looks for inappropriate data sharing, warning employees if they do something deemed potentially unsafe. However, this management mode lets the employee override the policy and share the data, logging the action to your audit log. For info about how to collect your audit log files, see How to collect Windows Information Protection (WIP) audit event logs.
    Silent WIP runs silently, logging inappropriate data sharing, without blocking anything that would have been prompted for employee interaction while in Allow Override mode. Unallowed actions, like apps inappropriately trying to access a network resource or WIP-protected data, are still stopped.
    Off WIP is turned off and doesn't help to protect or audit your data.

    After you turn off WIP, an attempt is made to decrypt any WIP-tagged files on the locally attached drives. Your previous decryption and policy info isn't automatically reapplied if you turn WIP protection back on. For more information, see How to disable Windows Information Protection.

  2. Select Save.

Define your enterprise-managed corporate identity

Corporate identity, typically expressed as your primary Internet domain (for example, contoso.com), helps to identify and tag your corporate data from apps you've marked as protected by WIP. For example, emails using contoso.com are identified as being corporate and are restricted by your Windows Information Protection policies.

Starting with Windows 10, version 1703, Intune automatically determines your corporate identity and adds it to the Corporate identity field.

To change your corporate identity

  1. From App policy, select the name of your policy, and then select Required settings.

  2. If the auto-defined identity isn't correct, you can change the info in the Corporate identity field.

    Microsoft Intune, Set your corporate identity for your organization.

  3. To add domains, such your email domain names, select Configure Advanced settings > Add network boundary and select Protected domains.

    Add protected domains.

Choose where apps can access enterprise data

After you've added a protection mode to your apps, you'll need to decide where those apps can access enterprise data on your network. Every WIP policy should include your enterprise network locations.

There are no default locations included with WIP, you must add each of your network locations. This area applies to any network endpoint device that gets an IP address in your enterprise's range and is also bound to one of your enterprise domains, including SMB shares. Local file system locations should just maintain encryption (for example, on local NTFS, FAT, ExFAT).

To define the network boundaries, select App policy > the name of your policy > Advanced settings > Add network boundary.

Microsoft Intune, Set where your apps can access enterprise data on your network.

Select the type of network boundary to add from the Boundary type box. Type a name for your boundary into the Name box, add your values to the Value box, based on the options covered in the following subsections, and then select OK.

Cloud resources

Specify the cloud resources to be treated as corporate and protected by WIP. For each cloud resource, you may also optionally specify a proxy server from your Internal proxy servers list to route traffic for this cloud resource. All traffic routed through your Internal proxy servers is considered enterprise.

Separate multiple resources with the "|" delimiter. For example:

URL <,proxy>|URL <,proxy>

Personal applications can access a cloud resource that has a blank space or an invalid character, such as a trailing dot in the URL.

To add a subdomain for a cloud resource, use a period (.) instead of an asterisk (*). For example, to add all subdomains within Office.com, use ".office.com" (without the quotation marks).

In some cases, such as when an app connects directly to a cloud resource through an IP address, Windows can't tell whether it's attempting to connect to an enterprise cloud resource or to a personal site. In this case, Windows blocks the connection by default. To stop Windows from automatically blocking these connections, you can add the /*AppCompat*/ string to the setting. For example:

URL <,proxy>|URL <,proxy>|/*AppCompat*/

When you use this string, we recommend that you also turn on Microsoft Entra Conditional Access, using the Domain joined or marked as compliant option, which blocks apps from accessing any enterprise cloud resources that are protected by conditional access.

Value format with proxy:

contoso.sharepoint.com,contoso.internalproxy1.com|contoso.visualstudio.com,contoso.internalproxy2.com

Value format without proxy:

contoso.sharepoint.com|contoso.visualstudio.com|contoso.onedrive.com,

Protected domains

Specify the domains used for identities in your environment. All traffic to the fully qualified domains appearing in this list will be protected. Separate multiple domains with the "|" delimiter.

exchange.contoso.com|contoso.com|region.contoso.com

Network domains

Specify the DNS suffixes used in your environment. All traffic to the fully qualified domains appearing in this list will be protected. Separate multiple resources with the "," delimiter.

corp.contoso.com,region.contoso.com

Proxy servers

Specify the proxy servers your devices will go through to reach your cloud resources. Using this server type indicates that the cloud resources you're connecting to are enterprise resources.

This list shouldn't include any servers listed in your Internal proxy servers list. Proxy servers must be used only for non-WIP-protected (non-enterprise) traffic. Separate multiple resources with the ";" delimiter.

proxy.contoso.com:80;proxy2.contoso.com:443

Internal proxy servers

Specify the internal proxy servers your devices will go through to reach your cloud resources. Using this server type indicates that the cloud resources you're connecting to are enterprise resources.

This list shouldn't include any servers listed in your Proxy servers list. Internal proxy servers must be used only for WIP-protected (enterprise) traffic. Separate multiple resources with the ";" delimiter.

contoso.internalproxy1.com;contoso.internalproxy2.com

IPv4 ranges

Specify the addresses for a valid IPv4 value range within your intranet. These addresses, used with your Network domain names, define your corporate network boundaries. Classless Inter-Domain Routing (CIDR) notation isn't supported.

Separate multiple ranges with the "," delimiter.

Starting IPv4 Address: 3.4.0.1
Ending IPv4 Address: 3.4.255.254
Custom URI: 3.4.0.1-3.4.255.254,
10.0.0.1-10.255.255.254

IPv6 ranges

Starting with Windows 10, version 1703, this field is optional.

Specify the addresses for a valid IPv6 value range within your intranet. These addresses, used with your network domain names, define your corporate network boundaries. Classless Inter-Domain Routing (CIDR) notation isn't supported.

Separate multiple ranges with the "," delimiter.

Starting IPv6 Address: 2a01:110::
Ending IPv6 Address: 2a01:110:7fff:ffff:ffff:ffff:ffff:ffff
Custom URI: 2a01:110:7fff:ffff:ffff:ffff:ffff:ffff,'<br>'fd00::-fdff:ffff:ffff:ffff:ffff:ffff:ffff:ffff

Neutral resources

Specify your authentication redirection endpoints for your company. These locations are considered enterprise or personal, based on the context of the connection before the redirection. Separate multiple resources with the "," delimiter.

sts.contoso.com,sts.contoso2.com

Decide if you want Windows to look for more network settings:

  • Enterprise Proxy Servers list is authoritative (do not auto-detect). Turn on if you want Windows to treat the proxy servers you specified in the network boundary definition as the complete list of proxy servers available on your network. If you turn this off, Windows will search for more proxy servers in your immediate network.

  • Enterprise IP Ranges list is authoritative (do not auto-detect). Turn on if you want Windows to treat the IP ranges you specified in the network boundary definition as the complete list of IP ranges available on your network. If you turn this off, Windows will search for more IP ranges on any domain-joined devices connected to your network.

Microsoft Intune, Choose if you want Windows to search for more proxy servers or IP ranges in your enterprise.

Upload your Data Recovery Agent (DRA) certificate

After you create and deploy your WIP policy to your employees, Windows begins to encrypt your corporate data on the employees' local device drive. If somehow the employees' local encryption keys get lost or revoked, the encrypted data can become unrecoverable. To help avoid this possibility, the Data Recovery Agent (DRA) certificate lets Windows use an included public key to encrypt the local data while you maintain the private key that can unencrypt the data.

Important

Using a DRA certificate isn't mandatory. However, we strongly recommend it. For more info about how to find and export your data recovery certificate, see Data Recovery and Encrypting File System (EFS). For more info about creating and verifying your EFS DRA certificate, see Create and verify an Encrypting File System (EFS) Data Recovery Agent (DRA) certificate.

To upload your DRA certificate

  1. From App policy, select the name of your policy, and then select Advanced settings from the menu that appears.

    Advanced settings shows.

  2. In the Upload a Data Recovery Agent (DRA) certificate to allow recovery of encrypted data box, select Browse to add a data recovery certificate for your policy.

    Microsoft Intune, Upload your Data Recovery Agent (DRA) certificate.

After you've decided where your protected apps can access enterprise data on your network, you can choose optional settings.

Advanced optional settings.

Revoke encryption keys on unenroll. Determines whether to revoke a user's local encryption keys from a device when it's unenrolled from Windows Information Protection. If the encryption keys are revoked, a user no longer has access to encrypted corporate data. The options are:

  • On, or not configured (recommended). Revokes local encryption keys from a device during unenrollment.

  • Off. Stop local encryption keys from being revoked from a device during unenrollment. For example, if you're migrating between Mobile Device Management (MDM) solutions.

Show the enterprise data protection icon. Determines whether the Windows Information Protection icon overlay appears on corporate files in the Save As and File Explorer views. The options are:

  • On. Allows the Windows Information Protection icon overlay to appear on corporate files in the Save As and File Explorer views. Also, for unenlightened but protected apps, the icon overlay also appears on the app tile and with Managed text on the app name in the Start menu.

  • Off, or not configured (recommended). Stops the Windows Information Protection icon overlay from appearing on corporate files or unenlightened, but protected apps. Not configured is the default option.

Use Azure RMS for WIP. Determines whether WIP uses Microsoft Azure Rights Management to apply EFS encryption to files that are copied from Windows 10 to USB or other removable drives so they can be securely shared with employees. In other words, WIP uses Azure Rights Management "machinery" to apply EFS encryption to files when they're copied to removable drives. You must already have Azure Rights Management set up. The EFS file encryption key is protected by the RMS template's license. Only users with permission to that template can read it from the removable drive. WIP can also integrate with Azure RMS by using the AllowAzureRMSForEDP and the RMSTemplateIDForEDP MDM settings in the EnterpriseDataProtection CSP.

  • On. Protects files that are copied to a removable drive. You can enter a TemplateID GUID to specify who can access the Azure Rights Management protected files, and for how long. The RMS template is only applied to the files on removable media, and is only used for access control—it doesn't actually apply Azure Information Protection to the files.

    If you don't specify an RMS template, it's a regular EFS file using a default RMS template that all users can access.

  • Off, or not configured. Stops WIP from encrypting Azure Rights Management files that are copied to a removable drive.

    Note

    Regardless of this setting, all files in OneDrive for Business will be encrypted, including moved Known Folders.

Allow Windows Search Indexer to search encrypted files. Determines whether to allow the Windows Search Indexer to index items that are encrypted, such as WIP protected files.

  • On. Starts Windows Search Indexer to index encrypted files.

  • Off, or not configured. Stops Windows Search Indexer from indexing encrypted files.

Encrypted file extensions

You can restrict which files are protected by WIP when they're downloaded from an SMB share within your enterprise network locations. If this setting is configured, only files with the extensions in the list will be encrypted. If this setting is not specified, the existing auto-encryption behavior is applied.

WIP encrypted file extensions.
