Intune and Zimperium – Part 2: Conditional access and mobile threat defense level

This week the second part about the integration between Microsoft Intune and Zimperium. A quick reminder, Zimperium is one of the available third-party Mobile Threat Defense connectors for Microsoft Intune. The first part, which is available here, was mainly about integrating Zimperium with Microsoft Intune. Including an overview of the total solution. In this second part, I’ll be providing a short introduction about the mobile threat defense levels and I’ll show how to configure conditional access in combination with these threat levels. Including how the different configurations are related. I’ll end this post with the end-user experience.

Introduction

Like last week, I’ll start with short introduction. Last week this introduction was about providing an overview about the integrated solution. This week is all about looking at the Mobile Threat Response Policy, the Conditional access policy and the Device compliance policy. To understand how these policies work together, it’s important to know how the Severity of a Mobile Threat Response Policy in Zimperium is related to the Mobile Threat Level of a Device compliance policy in Microsoft Intune. Below is an overview of how these two are related and how it’s used within the Require the device to be at or under the Mobile Threat Level setting of a Device compliance policy in Microsoft Intune.

Intune Zimperium Explanation from Intune-perspective
Secured Normal This is the most secure. The device is compliant only if no threats are found. If any threats are found, the device is evaluated as non-compliant.
Low Low The device is compliant if only low level threats are present. If anything higher is found, the device is evaluated as non-compliant.
Medium Elevated The device is compliant if only low or medium level threats are present. If high level threats are found, the device is evaluated as non-compliant.
High Critical This is the least secure. The device is compliant, no matter what threats are found. It only requires devices to have the MTD app installed and activated.

Configuration

Now let’s have a look at the configuration. The configuration flow basically contains three configuration levels. First configure the Mobile Threat Response Policy in Zimperium to specify the Severity of a threat, second configure the Device compliance policy in Microsoft Intune to specify the minimal Mobile Threat Level of the device and third, configure the Conditional access policy in Azure AD to require a compliant device to connect to cloud apps.

Zimperium configuration

Let’s start with the first configuration, the Mobile Threat Response Policy in Zimperium. The following 2 steps show how to locate the Mobile Threat Response Policy and how the configurations in that policy can influence the compliance state of device.

1 Open the Zimperium zConsole and navigate to POLICY and select a group to open the related Mobile Thread Response Policy;
2 In the Mobile Threat Response Policy, there are 2 important configurations (see below) that impact the mobile threat defense level of a device in Microsoft Intune.

Zimperium_MTRP

  1. Configure the Severity for a Threat. This configures the actual threat level that is reported to Microsoft Intune;
  2. Configure the MDM Action and Mitigation Action for a Threat. This configures the if the configured threat level is reported to Microsoft Intune or not.

Microsoft Intune configuration

Let’s continue with the second configuration, the Device compliance policy in Microsoft Intune. The following 4 steps show the minimum configuration of a Device compliance policy that is required to use the Mobile Threat Level in the compliance state of a device.

1 Open the Azure portal and navigate to Intune > Device compliance > Policies;
2 On the Device compliance – Policies blade, click Create Policy to open the Create Policy blade;
3 On the Create Policy blade, provide a unique Name select a Platform (iOS or Android) and click Configure > Device Health to open the Device Health blade;
4 On the Device Health blade, configure Require the device to be at or under the Mobile Threat Level setting and click OK;

Intune_DHP

Note: As mentioned in the introduction, this Mobile Threat Level corresponds to the different Severity levels that are sent by Zimperium.

Azure AD configuration

Let’s finish with the third configuration, the Conditional access policy in Azure AD. This can also be done via the Microsoft Intune section, but I like to use the Azure AD section for conditional access (related) configurations. The following 4 steps show the minimum configuration of a Conditional access policy that is required to use the compliance state of a device to grant or block access to cloud apps.

1 Open the Azure portal and navigate to Azure Active Directory > Conditional access;
2 On the Conditional access – Policies blade, click New Policy to open the New blade;
3 On the New blade, provide a unique Name, configure the Assignment (Users and groups and Cloud apps) and click Grant to open the Grant blade;
4 On the Grant blade, there are 2 important configurations (see below) that are required to require a compliant device;

AzureAD_CAP

    1. The conditional access policy must be enabled. This makes sure that the policy is applied;
    2. Select Grant access and at least Require device to be marked as compliant. This configures that a device is required to be compliant to be able to access the configured cloud apps.

End-user experience

Now let’s have a look at the end-user experience, from a Microsoft Intune perspective. Basically the end-user can receive two separate compliance issues related to Zimperium. Below are those examples for an Android device. On the left is an example of when the Zimperium connector is active, the Require the device to be at or under the Mobile Threat Level setting is configured and the Zimperium app (zIPS) is not installed. On the right is an example of when zIPS is installed and a threat is detected with a higher threat level as configured in the Require the device to be at or under the Mobile Threat Level setting. In that case, the end-user will be advised to look at zIPS for more information.

For iOS the end-user will receive similar messages. Below are the same examples, in the same order, for an iOS device.

Intune and Zimperium – Part 1: Configure the integration

This week and next week I’ll be looking at integrating Microsoft Intune with Zimperium. Zimperium is one the available third-party Mobile Threat Defense connectors for Microsoft Intune. This enables organizations to add an additional layer of protection to their corporate resources. More specifically, prevent access from compromised mobile devices. In the first part of this week I’ll be providing a short introduction about the integration and I’ll show how to configure the integration. I’ll end this post with the configuration results.

Introduction

Let’s start with a little introduction. Organizations can control mobile device access to corporate resources by using conditional access based on a risk assessment conducted by Zimperium. For this, Zimperium must be integrated with Microsoft Intune. The risk is assessed based on telemetry collected from devices running the Zimperium app. This enables organizations to configure conditional access policies based on the Zimperium risk assessment. The conditional access policy requires compliant devices and the compliance policy requires a minimum Mobile Threat Defense level. That combination enables organizations to allow or block non-compliant devices to access corporate resources based on detected threats.

To visualize this a bit more, it could be summarized in the following flow.

  1. The Zimperium app, on an iOS 8+ device or an Android 4.1+ device, detects a threat and sends an alert to the Zimperium cloud;
  2. The Zimperium cloud determines, based on the Mobile Thread Response Policy, the severity of the alert and sends the threat severity level to Microsoft Intune;
  3. Microsoft Intune determines, based on the configured mobile threat level, in the Device Compliance Policy, the compliance of the device and writes the device compliance to Azure AD;
  4. Azure AD determines, based on the configured access controls, in the Conditional Access Policy, if the device is allowed access to the cloud app.

Configuration

Now let’s have a look at the actual configuration of the integration between Zimperium and Microsoft Intune. The connector. Before starting with the configuration make sure that the following is available:

  • Microsoft Intune subscription;
  • Azure Active Directory administrative credentials;
  • Zimperium zConsole administrative credentials.

Zimperium configuration

The actual configuration starts in the Zimperium zConsole and not in the Intune section of the Azure portal. The Intune section in the Azure portal will only refer to the Zimperium zConsole. The 6 steps below walk through the configuration in cloud version of Zimperium.

1 Open the Zimperium zConsole and navigate to MANAGEMENT > MDM Settings;
2 Click Edit to open the Edit MDM dialog box;

Note: This environment had a previous MDM configuration. A clean environment has an Add MDM option. In that case every screen will show Edit instead of Add.

3 EditMDM01At Step 1, select Microsoft Intune and click Next;.
4a EditMDM02At Step 2, click Add to Azure Active Directory for the different components and click Next;

Note: Step 4b, 4c and 4d provide more details about the required permissions per component.

4b EditMDM02_zConsoleZimperium zConsole needs the following permissions:

  • Send device threat information to Microsoft Intune;
  • Read directory data;
  • Sign in and read user profile;
  • Read directory data.

Note: This makes sure that Zimperium can synchronize user and devices from Microsoft Intune and that Zimperium can sent threat information to Microsoft Intune.

4c EditMDM02_zIPSiOSZimperium zIPS iOS needs the following permissions:

  • Access Zimperium zConsole (Zimperium zConsole);
  • Sign in and read user profile.

Note: This makes sure that the Zimperium zIPS iOS app can use the auto sign-in functionality by using the Microsoft Intune enrollment user information.

4d EditMDM02_zIPSAndroidZimperium zIPS Android needs the following permissions:

  • Access Zimperium zConsole (Zimperium zConsole);
  • Sign in and read user profile.

Note: This makes sure that the Zimperium zIPS Android app can use the auto sign-in functionality by using the Microsoft Intune enrollment user information.

5 EditMDM03At Step 3, verify the information and click Next;
6 EditMDM04At Step 4, select the MDM group(s) that should be synchronized and used for the integration between Microsoft Intune and Zimperium and click Finish.

Note: The users in this group, and their devices, are synchronized to Zimperium.

Note: The connector between Zimperium and Intune automatically synchronizes and the synchronization schedule can be customized. This synchronization can also be manually triggered (see the Results section).

Microsoft Intune configuration

After performing the configuration in the Zimperium zConsole, the connector will be created in Microsoft Intune. This enables a few tuning options from Microsoft Intune perspective. The following 3 steps walk through the configuration options.

1 Open the Azure portal and navigate to Intune > Device compliance > Mobile Threat Defense;
2 On the Device compliance – Mobile Threat Defense blade, select the automatically created MTD CONNECTOR Zimperium;
3 IntuneZimperiumConnectorOn the Edit Connector blade, configure the connected devices and click Save.

Note: This enables the administrator to differentiate between the available platforms.

Results

When the configurations are completed, a successful configuration can be verified in the Zimperium zConsole (below on the right) and in the Azure portal (below on the left). Both will show the same synchronization time.
