KNOX Device Management

KNOX Device Management commences with the process of creating a KNOX Container within the device. A KNOX License is the basic requirement to activate a KNOX Container on the device. KNOX License management includes the following:

Creating KNOX Portal Account

Managing KNOX devices requires a KNOX Workspace License that can be directly purchased from KNOX Marketplace. For purchasing KNOX Licenses, it is necessary to create a KNOX Portal Account. For creating the account and purchasing licenses, refer to this

Uploading Licenses to Mobile Device Manager Plus

On purchasing the required licenses, it is mandatory to upload the License Key to Mobile Device Manager Plusserver to facilitate the distribution of licenses and management of devices. Refer to the steps given below to upload licenses to Mobile Device Manager Plus:

  1. On the web console, navigate to KNOX -> Upload License

  2. Copy and Paste the License Key in the space provided and specify the number of devices to be managed using the licenses, in Device Count.

  3. Mention the Expiry Date provided by Samsung, to receive notification regarding License Expiry.

  4. Click Save

Mobile Device Manager Plus does not validate the License Key details or Expiry Date. Any error in the given data would reflect only when the KNOX container is created and the process would fail. If required, you can check the validity of the KNOX Workspace License Key using "Check License Key" option after logging in to your KNOX Portal Account.

Distributing Licenses to Groups/Devices

KNOX licenses can be distributed by following the steps given below:

  1. On the web console, go to  KNOX -> Distribute Licenses

  2. Select the License Distribution Option as Automatically or Manually.
    Selecting the option Automatically, enables you to apply KNOX licenses automatically to all KNOX devices or Groups during enrollment. In case you select Groups, mention the groups to which the licenses must be automatically applied. Choosing "Automatic Distribution" will distribute the licenses only to devices which will be enrolled henceforth. On selecting the option Manually, licenses can be manually applied to the devices listed in KNOX Devices tab after enrollment. This can be done by selecting the devices and then selecting Create Container button.                                                                                                                                                                                                                                                                                                                                        

  3. Enable the check box to "Overwrite the existing KNOX container created by user" if necessary.
    This option is applicable only for KNOX v1.0 devices, since other KNOX devices support multiple containers. If this check box is not enabled while distributing licenses to KNOX v1.0 devices, KNOX containers will not be created in the devices. However, the KNOX license would get distributed to the device. On overwriting the existing KNOX container present in the device, all data present in the existing container is lost and no notification is issued to the user for data backup.

  4. Click Save

When a license gets applied to a device, then a KNOX container is created within the device. Users can access all the corporate data and apps distributed to the device by entering the KNOX container.

In case the number of enrolled KNOX devices exceeds the count of available licenses, then the licenses would not get applied to the extra devices. This requires you to purchase new licenses and then upload to Mobile Device Manager Plusin order to distribute them to devices.

Revoking KNOX Licenses

When a particular user's device no longer needs to be managed, you can revoke the KNOX license from that device and reuse it on a different device. Refer to the steps given below to revoke KNOX licenses from devices:

  1. On the web console, go to KNOX -> KNOX Devices

  2. Select the devices from which you choose to revoke the licenses.

  3. Select Remove Container.

The licenses will be revoked from the selected devices. On revoking the licenses, the KNOX container would be removed from the devices.

In case you want to redistribute the revoked licenses, choose the required devices and then select Create Container. The licenses would get redistributed to the selected devices.

Adding more KNOX Licenses

If you purchase more licenses to manage additional devices, you have to modify the license details which were uploaded earlier. In that case, you may follow the steps mentioned below:

  1. On the web console, navigate to KNOX -> Upload License

  2. Select Modify and make the required modifications.

  3. Click Save

Now, the modified licenses would get automatically reapplied to the devices irrespective of the Distribution Settings.

You need to modify only the Device Count while purchasing additional licenses to manage extra devices, as it will not modify the License Key uploaded on Mobile Device Manager Plus.

KNOX License Expiry and Renewal

Mobile Device Manager Plus will start displaying notifications regarding the expiry of licenses, 30 days prior to the license Expiry Date. In case the license expires, the KNOX Container gets locked and the user will not be able to access the container. Hence, on expiry of KNOX licenses, you must purchase new licenses or renew the existing licenses from your KNOX Portal Account. Refer to this, to know more.

If you extend the validity of the existing licenses alone, mention the correct Expiry Date while modifying license details and the licenses will be automatically reapplied to the devices. To modify license details, navigate to KNOX -> Upload License and click on Modify tab.

Best Practices for KNOX

Disabling Device Administrator

If the user disables Device Administrator in the device, then the container will be removed from the device and the license will be disassociated in server. For exercising better management activities on mobile devices, it is recommended to restrict users from disabling Device Administrator from their devices. This limits users' ability to remove ME MDM App from their mobile devices.

Creating exclusive Group for KNOX

It is advisable to create a Group dedicated to KNOX devices in Mobile Device Manager Plus. This enables easy management of KNOX devices by saving time during Profile and App Management.

Restricting contact between Device and Container

Restricting the transfer of data between the device and container ensures higher level of security by not permitting corporate data loss. This can be carried out by configuring corporate Email to be accessed only from the container, disabling sharing of "Contacts" to device while creating profile for KNOX Container Restrictions, etc.

Passcode policy for Container

It is advisable to select a Complex Value type passcode to secure containers. Also, it is best to keep the maximum number of failed attempts at the lowest value for better security. Allowing the container to stay idle for the least value of time and setting it to Auto-lock on exceeding the time limit specified, confirms that your container remains protected.

Container Restrictions

You can enforce stringent restrictions like disabling the use of camera and "share via" list, to keep the KNOX Container highly secured.

Upgrading to latest version of KNOX

It is highly recommended to upgrade your Android KNOX to the latest version, in order to distribute Apps to KNOX Container by avoiding the process of "App Wrapping".
