Android Samsung Knox Container Settings

A Samsung KNOX container configuration creates a secure container on Samsung KNOX devices (API 4.0+). Apps in the KNOX container cannot communicate with apps outside of the container. Data in the secure container cannot be sent outside of the container.

Sharing Bluetooth data from within the KNOX Workspace is controlled by a device-level setting by the user. You must enable Bluetooth in the Lockdown policy by going to Policy & Configs > Policies > Lockdown and selecting the Bluetooth Enable radio button.

To configure the Samsung KNOX Workspace mode:

1. In the Admin Portal, go to Policies & Configs > Configurations >Add New > Android > Samsung KNOX Container. The New Samsung KNOX Container Setting dialog box opens.
2. In the Authentication section, enter the password rules and behavior you want to enforce.
3. In the App Settings section, use the drop-downs to select settings for Browser, Exchange, and VPN in the container.

See Samsung Knox support for information about configuring Samsung KNOX.

Use these settings to:

• specify requirements for the container password.
• specify which apps to install in the container.
• specify restrictions.
• select the Android Samsung browser configuration to use in the container.
• select the Exchange configuration to use in the container.
• select the VPN configuration to use in the container.

Make sure only one Samsung KNOX container setting applies to each device.

Item	Description
Name	Enter brief text that identifies this group of Samsung KNOX container settings.
Description	Enter additional text that clarifies the purpose of this group of Samsung KNOX container settings.
Authentication
Enforce Multi-Factor Authentication	Select On to require the device user to enter both a password and a fingerprint to access the Samsung KNOX container. Therefore, the device user must create a fingerprint on the device. The default is Off. Enforcing multi-factor authentication requires the following on the device: •Mobile@Work 9.1 for Android •Samsung KNOX 2.2 or supported newer versions   Important: After multi-factor authentication has been enforced on a device, changing this setting to Off has no impact on the device. Multi-factor authentication is still enforced, as designed by Samsung.
Password Type	Select the kind of password to require: •Simple: (Supported only on devices with Mobile@Work 8.0 and KNOX version 2.0). •Alphanumeric: Must include at least one alphabetic and one numeric character. •Complex: Must include at least one alphabetic, one numeric, and one special character (i.e., a symbol).
Min Password Length	Specify a minimum length for the password. Valid range is 4-16. The default value is 6.
Min Number of Complex Characters	Specify the minimum number of complex characters for the passcode. Valid range is 0-10. For example, to require at least two complex characters in the passcode, enter 2.
Max Character Occurrences	Specify a limit for the number of times a specific character can occur in the passcode. For example, to prevent a specific character from occurring 3 or more times, enter 2.
Max Character Sequence Length	Specify a limit for the number of characters that can appear in sequence in a passcode. For example, to prevent abc from occurring in a passcode, enter 2.
Max Numeric Sequence Length	Specify a limit for the number of numeric characters that can appear in sequence in a passcode. For example, to prevent “123” from occurring in a passcode, enter 2.
Min Character Change Length	Specify a minimum number of characters that must change when the passcode is reset. For example, to ensure that at least 2 characters change, enter 2.
Forbidden Strings	Specify any strings that must not be present in the passcode. To add a string: Click + to add an entry. Click the “Name” placeholder in the new entry. Replace “Name” with the string you want to add. For example, to prevent the passcode from including the user’s email address or last name, enter $EMAIL$, $LAST_NAME. Use the tool tip to see a list of substitution variables you can use here.

Samsung Knox Dual Encryption (DualDAR) support

Using two layers of encryption, Dual Encryption (DualDAR) secures and protects sensitive data on devices - even when they are powered off or in an unauthenticated state. This reduces the possibility of enterprise work data becoming compromised. Samsung Knox includes a FIPS 140-2 certified encryption module within the inner layer. (FIPS (Federal Information Processing Standard Publication) 140-2 is a U.S. government computer security standard used to approve cryptographic modules.)

Within the workspace, there are two storage locations available to an app: Credential Encrypted (CE) storage and Device Encrypted (DE) storage. From an apps standpoint, the Workspace storage is DualDAR-protected and works as CE storage. For apps that do not have DualDAR protection, the Knox framework prevents any apps from writing data to any storage space.

DualDAR is applicable to Knox v3 on Android 8.0 or supported newer versions.

DualDAR is applicable to Android Enterprise:

• Work Profile mode

• Managed Device with Work Profile mode

• Work Profile on Company Owned Device mode

Procedure 

1. Edit the Android Enterprise configuration. The Android enterprise (all modes) Setting dialog box opens.

2. Select the Enable DualDAR check box. By default, this check box is de-selected.

   DualDAR is only supported on Knox 3.3+ devices. DualDAR requires a special license that can be used instead of the Samsung General policy configurator.

3. Enter the Knox License key into the Samsung DualDAR Version field.
4. Click Save.

The Core server will push the new Samsung DualDAR report to the device upon device registration. If enabled, the Mobile@Work for Android client will report the Samsung DualDAR version in the Device Details page > Samsung KNOX Version field. If not enabled or the device is in Device Owner mode, "unsupported" will display in the Samsung KNOX Version field.

Samsung KNOX Workspace support for Google Play

You can enable users to use Google Play inside the Samsung KNOX Workspace. Account whitelisting is supported for Google Play Services account types. Other account types, such as accounts defined by an application such as Gmail or Facebook, are not exempted by this whitelist as they are of a different account type. Therefore, it is important to avoid whitelisting applications that can allow undesired accounts into the KNOX Workspace.

Users are only permitted to download apps that are whitelisted for the Samsung KNOX Container, but they are still able to browse the entire contents of the Google Play Store.

To enable Samsung KNOX Workspace support for Google Play:

1. In the Admin Portal, go to Policies & Configs > Configurations >Add New > Android > Samsung KNOX Container to open the New Samsung KNOX Container Settings dialog box.
2. In the Restrictions section, select Google Play Store: On radio button to enable the Google Play Store. It is set to Off by default.
3. Optionally, in the Whitelist Google Accounts field, select the Account check box to enter the domain URL or wildcard domain. This specifies which Google accounts or wildcard domains may be used inside the KNOX Container.
4. Save your changes.

Tunnel support in the Samsung Knox Workspace

You can configure Tunnel support on Android devices. For detailed information on support and setup for Tunnel in the Samsung KNOX container, see the Tunnel for Android Guide.

On-Demand Support for Samsung Knox VPN connections

You can enable On-Demand for Samsung KNOX for VPN apps that support On-Demand connections.

On-Demand is not supported for container-wide VPN apps.

To enable On-Demand for Samsung KNOX:

1. In the Admin Portal, go to Policies & Configs > Configurations >Add New > VPN. The Add VPN Setting dialog box opens.
2. In the Connection Type drop-down menu, select the Samsung KNOX IPSec check box. This is a VPN app that supports On-Demand.
3. Enter the information for the Server, Username, and Password.
4. Select the VPN on Demand check box.
5. Select the Per-app VPN Yes radio button.
6. Click Save.
