Device Classification for Android

You can classify Android devices based on these criteria:

Create Device Classification Rule for Versions From 127.0.0 Or Later

Earlier, the Device Classification Rules webUI provided only the Match Any or Match All operators to choose  between criteria in a Device Classification rule. With the release of version 127.0.0, Netskope extends the support for the usage of logical operators AND/OR between criteria in a Device Classification rule.

The logical operators work at three levels in a Device Classification Rule:

• Apply logical operators globally across all Criteria Groups within a device classification rule.
• Apply logical operators within a Criteria Group.

To create a device classification rule for Android:

1. Go to Settings > Manage > Device Classification.
2. Select Android on the New Device Classification dropdown list.
3. Follow these steps to classify your iOS device. Select options and enter the requested parameters.
   • Rule Name: Enter a name for this classification rule.
   • Device Classification: From the options displayed in the dropdown menu, choose the desired label you want to assign to this rule. You cannot assign more than one label to a rule.
   • Classification Criteria: In  Add Criteria Group, select one of the following options. You can create up to 16 criteria groups within a device classification rule.
     • OS – Minimum OS Version: Select an OS version from the dropdown list or create a custom OS version.
     • Passcode Required: Passcode check is an API call that validates if the device has configured any unlock code. The check fails for devices with no unlock code. No parameters required.
     • Compromise – Device Not Compromised:  To check if the critical system files in Android devices are compromised such as Jailbreaking or rooting. No parameters required.
     • Encryption – Primary Storage Encrypted: To determine whether the device is encrypted. No parameters required.
     • Managed Configuration: If you already added a managed configuration for this device on the MDM Distribution page, the key-value pair is shown here. This key-value pair is sent from the MDM to the device so the Netskope app can validate the key-value pair and mark it as Managed or Unmanaged. To regenerate the key-value pair, click Regenerate.

       Note

       Managed Configuration does not work when an app is installed on an Android device using the onboarding email or with the AirWatch SDK.

4. Click Add Criterion to add more than one device classification option. You cannot add the same option twice in a single Criteria Group. The selected options remain greyed-out in a Criteria Group.
5. After you complete adding all the required criteria in the first group, select the logical operator Match All (AND) or Match Any (OR) to compare the criteria in the Device Classification Rule.
6. Choose and add the required criteria in the second group along with the logical operator for that Criteria Group.
7. Choose the logical operator to match the various criteria added in each group.
8. When finished, click Save.

Create Device Classification Rule for Versions Prior to 127.0.0

Go to Settings > Manage > Device Classification and select Android on the New Device Classification dropdown list, and then follow these steps to classify your Android device. Select options and enter the requested parameters.

Configure a Real-time Protection Policy

After creating a device classification rule, you can use it in a Real-time Protection policy.

1. To use this Device Classification in a Real-time Protection policy, click Policies > Real-time Protection in the Netskope UI. Select an existing policy or click New Policy and choose a policy type.

2. Proceed through the Users, Cloud Apps + Web, DLP/Threat Protection, and Select Activities sections.

3. For Additional Attributes, click Access Method and select either Client, Mobile Profile, or Reverse Proxy, and then click Save. Click Device Classification, and then select label from Custom Device Management and Managed or Unmanaged from Device Classification, based on the devices you just classified.

   • Managed means the device is managed; the device posture information sent by the Client matches at least one of the device classification checks configured for that Client’s OS.

   • Unmanaged means the device is unmanaged; the device posture information sent by the Client matches none of the device classification checks configured for that Client’s OS.

4. When finished, click Save and then Next.

5. Combine device classification with other policy elements, like using the Block Action for specified applications for activities like uploading files from managed or unmanaged devices. Finish creating or updating this policy to establish this device classification. Click Apply Changes for this policy.

6. After the policy has been created, perform the process for which the policy was created. Next go to Skope IT > Application Events and click the magnifying icon for an event to open the Application Event Details panel. In the User section you’ll see a Device Classification field, which shows one of these device classifications.
