Block app access for unapproved device manufacturers or device models

This week is all about app protection. More specifically, this week is all about the just introduced capability to block app access for Android devices with unapproved device manufactures , or for iOS devices with unapproved device models. That capability actually has two separate actions to choose from, 1) block app access and 2) selective wipe of corporate data within the app. This capability will help with preventing access from untrusted devices to corporate data. Really useful, as we all can think of some low-end devices (loaded with malware, almost for free) that should not be used for accessing corporate data. In this post I’ll show the available configuration options, followed by the end-user experience.

Configuration

Now let’s start by having a look at the available configuration options. I’ll do that by walking through the steps for creating and configuring an app protection policy. These steps are shown below, with an extra focus on the policy settings (see step 5a and 5b). After the creation of the app protection policy, simply assign it the applicable user group.

1 Open the Azure portal and navigate to Intune > Mobile apps > App protection policies;
2 On the Mobile apps – App protection policies blade, click Add a policy to open the Add a policy blade;
3

On the Add a policy blade, select iOS or Android with Platform and select Yes with Target to all app types.

Note: The main configuration of this post can be used in combination with managed devices and unmanaged devices.

4 On the Add a policy blade, select Apps to open the Apps blade. On the Apps blade, select one or more apps from the list to associate them with the policy and click Select. Depending on the platform continue with step 5a, or step 5b;
5a

On the Add a policy blade, select Settings to open the Settings blade. On the Settings blade, and having iOS selected with Platform, navigate to Access Action and select Device model(s) on a new line as SETTING. As a VALUE specify the allowed models, select as ACTION to either Allow specified (Block non-specified) or Allow specified (Wipe non-specified) and click OK;

Note: The iOS model identifier can be found under the “Device Type” column in HockeyApp’s support documentation and to specify multiple allowed device models, use a semi-colon (;) to separate them.

On the Add a policy blade, select Settings to open the Settings blade. On the Settings blade, and having Android selected with Platform, navigate to Access Action and select Device manufacturer(s) on a new line as SETTING. As a VALUE specify the allowed manufacturers, select as ACTION to either Allow specified (Block non-specified) or Allow specified (Wipe non-specified) and click OK;

Note: To specify multiple allowed device manufacturers, use a semi-colon (;) to separate them.

Note: On iOS devices, this feature requires the participation of applications (such as WXP, Outlook, Managed Browser, Yammer) to integrate the Intune APP SDK for this feature to be enforced with the targeted applications. On Android, this feature requires the latest Company Portal app.

End-user experience

Now let’s end this post by having a look at the end-user experience. I’ll do that by showing the end-user behavior on an iOS device. For experiencing the different messages, I made sure that my iPad would not be allowed. Below on the left is an example of the App Access Blocked message in the Outlook app, which clearly explains to the end-user that the iOS model is not allowed. Below on the right is an example of the Org Data Removal message in the Outlook app, which clearly explains to the end-user that the iOS model is not allowed and that associated data will be removed.

App protection policies and device management state

This week is all about creating some additional awareness for the capability of assigning app protection policies and differentiating between the management state of the devices of the user. Since recently it’s possible to assign app protection policies to either Intune managed devices or unmanaged devices. This can help with differentiating between Intune managed devices and unmanaged (MAM only) devices. For example, have more strict data loss prevention configurations for MAM only devices compared to MDM managed devices. In this post I’ll show the available configuration followed by results from an administrator perspective.

Configuration

Let’s start by having a look at the available configuration options. I’ll do that by walking through the steps for creating and configuring an app protection policy. These steps are shown below, with an extra focus on the targeted app types (see step 3a and 3b). After the creation of the app protection policy, simply assign it the applicable user group.

1 Open the Azure portal and navigate to Intune > Mobile apps > App protection policies;
2 On the Mobile apps – App protection policies blade, click Add a policy to open the Add a policy blade. Depending on the platform continue with step 3a, or step 3b;
3a

MAM-iOSOn the Add a policy blade, select iOS as Platform and select No with Target to all app types. This enables the App types selection. In the App types selection choose between Apps on unmanaged devices and Apps on Intune managed devices;

Note: This enables the administrator to differentiate between MAM only devices and MDM managed devices.

3b MAM-Android

On the Add a policy blade, select Android as Platform and select No with Target to all app types. This enables the App types selection. In the App types selection choose between Apps on unmanaged devices, Apps on Intune managed devices and Apps in Android Work Profile;

Note: This enables the administrator to differentiate between MAM only devices, MDM managed devices and MDM managed devices with Android Enterprise.

4 On the Add a policy blade, select Apps to open the Apps blade. On the Apps blade, select one or more apps from the list to associate them with the policy and click Select;
5 On the Add a policy blade, select Settings to open the Settings blade. On the Settings blade, configure the policy settings related to data relocation (data movement in and out apps) and access (access apps in work context) and click OK;
6 On the Add a policy blade, click Create;

Note: This post is focused on iOS and Android devices, but for Windows 10 it’s also possible to differentiate between devices with enrollment and devices without enrollment.

Result

Now let’s end this post by looking at the results of the configuration. There are many things to look at, but it will be hard to show the difference in behavior via screenshots. That’s why an overview of my policies is the easiest way to show the difference in policies. Below is an overview of the different platforms and the different management types.
