Add apps to your Windows Information Protection (WIP) policy by using Microsoft Intune custom URI functionality (Windows 10) Add apps to your Windows Information Protection (WIP) allowed app list, by using the Microsoft Intune custom URI functionality and AppLocker. b50db35d-a2a9-4b78-a95d-a1b066e66880 WIP, Enterprise Data Protection, protected apps, protected app list w10 explore security library eross-msft high

Add apps to your Windows Information Protection (WIP) policy by using the Microsoft Intune custom URI functionality

Applies to:

  • Windows 10, version 1703
  • Windows 10 Mobile, version 1703

You can add apps to your Windows Information Protection (WIP) protected app list using the Microsoft Intune custom URI functionality and AppLocker. For more info about how to create a custom URI using Intune, Windows 10 custom policy settings in Microsoft Intune.

Important

Results can be unpredictable if you configure your policy using both the UI and the Custom URI method together. We recommend using a single method for each policy.

Add Store apps

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

  2. In the left pane, expand Application Control Policies, expand AppLocker, and then click Packaged App Rules, and then right-click and choose Automatically Generate Rules.

    The Automatically Generate Packaged app Rules wizard opens, letting you create WIP-protected app policies for all the installed apps on a device or for packaged apps within a specific folder.

  3. In the Applications and Permissions screen, keep the default of Everyone in the User or security group that the rules will apply to box.

    Keeping this value applies your WIP policy to the managed device, not to a single user or group of users.

  4. Type the name youll use to tag the rules into the Name to identify this set of rules box, and then click Next.

    This name should be easily recognizable. For the purposes of this topic, we've used WIP_StoreApps_Rules.

  5. In the Rule Preferences screen, keep the default settings, and then click Next to start generating the rules.

    Note

    We recommend that you use Publisher rules because they only work with apps you've specifically defined and they can be configured to not require updating simply because a new version came out.

    If you can't use Publisher rules, we then recommend that you use File hash rules. File hash rules are a secure alternative that can be used on unsigned code. The primary disadvantage to File hash is that every time a binary changes (such as, through servicing updates or upgrades), you'll need to create a new rule.

  6. In the Review Rules screen, look over your rules to make sure theyre right, and then click Create to add them to your collection of rules.

  7. In the left pane, right-click AppLocker, click Export Policies, go to where you want to save the XML file and type a file name, click Save, and then clear your AppLocker rules.

    Important

    Be aware that what you're saving are the actual AppLocker rules using your local policy. You don't want to apply these rules to your employee devices, you just want to use them to create and export the XML content. You must delete the AppLocker rules before you apply your policy.

    Important

    You can also use Path rules instead of the File hash if you have concerns about unsigned files potentially changing the hash value if they're updated in the future.

    Note

    We recommend that you use Publisher rules because they only work with apps you've specifically defined and they can be configured to not require updating simply because a new version came out.

    If you can't use Publisher rules, we then recommend that you use File hash rules. File hash rules are a secure alternative that can be used on unsigned code. The primary disadvantage to File hash is that every time a binary changes (such as, through servicing updates or upgrades), you'll need to create a new rule.

    Finally, there's Path rules. Path rules are easier to set up and maintain, but can let apps bypass Windows Information Protection (WIP) by simply renaming and moving an unallowed file to match one of the apps on the Protected App list. For example, if your Path rule says to allow %PROGRAMFILES%/NOTEPAD.EXE, it becomes possible to rename DisallowedApp.exe to Notepad.exe, move it into the specified path above, and have it suddenly be allowed.

  6. In the Review Rules screen, look over your rules to make sure theyre right, and then click Create to add them to your collection of rules.
