Authenticate with each other 2. Exchange configuration information 3. The BlackBerry Infrastructure performs one of the following actions: Accepts the challenge response and sends a confirmation to the BlackBerry Device Service to complete the authentication process and configure an authenticated SRP connection Rejects the challenge response If the BlackBerry Infrastructure rejects the challenge response, the authentication process is not successful.
No intermediate point decrypts and encrypts the data again. After the activation process begins, no data traffic of any kind can occur between the BlackBerry Device Service and an activated device unless the BlackBerry Device Service can decrypt the data using a valid device transport key. Only the BlackBerry Device Service and the device have the correct device transport key. You must configure your organization s firewall or proxy server to permit the BlackBerry Device Service to start and maintain an outgoing connection to the BlackBerry Infrastructure over TCP port. By default, devices attempt to connect to your organization s network using the following communication methods, in order: Work VPN profiles that you configure 2.
Work Wi-Fi profiles that you configure 3. BlackBerry Infrastructure 4. By default, work apps on the device can also use any of these communication methods to access the resources in your organization s environment for example, Microsoft ActiveSync servers, web servers, and content servers.

The data that the device and work wireless access point send to each other uses Wi-Fi encryption unless the work wireless access point is an open network. Because the device uses tunneling, the data that the device sends to the BlackBerry Device Service is encrypted first by SSL encryption and then by Wi-Fi encryption as it travels between the device and the wireless access point. Encrypts the data that is sent between the device and VPN server.
Encrypts the data that is sent between the device and BlackBerry Infrastructure. Encrypts the data that is sent between the device and BlackBerry Device Service. Encrypts the data that is sent between the device and content server, web server, or messaging server that uses Microsoft ActiveSync. The encryption for this connection must be set up separately on each server and uses a separate certificate with each server.
This type of encryption uses the device transport key. Work Wi-Fi connection In a work Wi-Fi connection, a device connects to your organization s resources through a work Wi-Fi connection that you set up. Wi-Fi encryption is only used if the wireless access point was set up to use Wi-Fi encryption. VPN connection In a VPN connection, a device connects to your organization s resources through any wireless access point or a mobile network, your organization s firewall, and your organization s VPN server.
If the security requirements of your organization do not permit personal apps to access your organization s network, you can restrict connection options. You can also limit the communication methods that a device can use to connect to your organization's network through the BlackBerry Device Service by limiting connectivity options to the BlackBerry MDS Connection Service and the BlackBerry Infrastructure.

The device uses TLS to encrypt data that an app sends to content servers. You can use TLS when only the end points of the transaction are trusted for example, with banking services. Kerberos NTLM Devices can use the same Kerberos configuration file for single sign-on access that your organization uses to authenticate users for single sign-on access from their computers. For internal websites that use password-based authentication, you can specify a list of trusted domains.
After a user enters their password in the work space browser the first time that they visit any site in the trusted domain, the device uses the same password for all sites in the trusted domain and no longer prompts the user for the password. For more information, visit docs. Using Kerberos to provide single sign-on from BlackBerry 10 devices If your organization uses Kerberos to provide users with single sign-on access to your organization's resources, you can also provide users with single sign-on access to your organization's resources from the browser in the work space on their BlackBerry 10 devices.
When Kerberos is implemented within the BlackBerry Device Service, if a valid TGT is available on a user's device, the user is not prompted for login information when accessing your organizations internal resources from the browser in the work space. If the user is connected to your organization using a VPN connection, the VPN gateway must permit traffic to the KDC to pass through for users to have access without providing login information.
The BlackBerry Device Service can allow devices that are not connected to your organization's internal network or do not have a VPN connection to synchronize with the messaging server without requiring you to make connections to Microsoft ActiveSync available from outside the firewall.
The BlackBerry Device Service allows devices to synchronize securely with the messaging server over the BlackBerry Infrastructure using the same encryption methods that it uses for all other work data. If your organization uses SCEP to enroll certificates to devices, you can associate a SCEP profile with an profile to require certificate-based authentication to help protect connections between devices and the messaging server.
A TLS connection between a device and the BlackBerry Infrastructure is designed so that an attacker cannot use the TLS connection to send data to or receive data from the device. If an attacker tries to impersonate the BlackBerry Infrastructure, devices prevent the connection. Devices verify whether the public key of the TLS certificate of the BlackBerry Infrastructure matches the private key of the root certificate that is preloaded on the devices during the manufacturing process.
If a user accepts a certificate that is not valid, the connection cannot open unless the device can also authenticate with a valid BlackBerry Device Service. The device uses a root certificate that is preloaded on the device to verify the TLS certificate. If the user deleted the root certificate, the device prompts the user to trust the TLS certificate. The device opens the TLS connection. BlackBerry transport layer encryption is designed to encrypt data in transit over the BlackBerry Infrastructure. Before the BlackBerry Device Service and devices send data to each other, they compress the data, encrypt the data using message keys, and encrypt the message keys using the device transport key.
When the BlackBerry Device Service and devices receive data from each other, they decrypt the message keys using the device transport key, decrypt the data, and then decompress the data. Device transport keys The device transport key encrypts the message keys that help protect the data that is sent between the BlackBerry Device Service and devices.
The BlackBerry Device Service and a device generate the device transport key when a user activates the device. Only the BlackBerry Device Service and the device know the value of the device transport key. The BlackBerry Device Service and the device reject a data packet if they do not recognize the format of a data packet or do not recognize the device transport key that protects the data packet.
The keystore database prevents an attacker from copying the device transport keys to a computer by trying to back up the device transport keys. An attacker cannot extract key data from flash memory. To avoid compromising the device transport keys that are stored in the BlackBerry Configuration Database, you must protect the BlackBerry Configuration Database.
Related information Protecting the data that the BlackBerry Device Service stores in your organization's environment, Generating the device transport key for a device When you install the BlackBerry Device Service, the setup application creates an enterprise management root certificate and a server certificate for the BlackBerry Device Service.
The BlackBerry Device Service uses the CSR to create a client certificate, signs the client certificate with the enterprise management root certificate, and sends the client certificate and the enterprise management root certificate for the BlackBerry Device Service to the device. When the certificate exchange is complete, the device and BlackBerry Device Service establish a mutually authenticated TLS connection using the client certificate and the server certificate.
The device verifies the server certificate using the enterprise management root certificate. To generate the device transport key, the device and the BlackBerry Device Service use the authenticated long-term public keys that are associated with the client certificate and with the server certificate for the BlackBerry Device Service, and ECMQV. The BlackBerry Device Service and device do not send the device transport key over the wireless network when they generate the device transport key or when they exchange messages.
Message keys The BlackBerry Device Service and a device generate one or more message keys that protect the integrity of the data for example, short keys or large messages that the BlackBerry Device Service and the device send between each other using the BlackBerry Infrastructure. If a message exceeds 2 KB and consists of several data packets, the BlackBerry Device Service and the device generate a unique message key for each data packet.
Each message key consists of random data that makes it difficult for a third party to decrypt, re-create, or duplicate the message key. The BlackBerry Device Service and the device do not store the message keys in persistent storage. They free the memory that is associated with the message keys after the BlackBerry Device Service or device uses the message keys to decrypt the message.
The device uses bits retrieved from the randomization source on the device to generate a pseudorandom high entropy message key. To generate a message key, the device performs the following actions: Retrieves random data from multiple sources to generate the seed using a technique that the device derives from the initialization function of the ARC4 encryption algorithm 2. Uses the random data to reorder the contents of a byte state array 3. Adds the byte state array into the ARC4 encryption algorithm to further randomize the byte state array 4.
Uses SHA to hash the byte value to 64 bytes 6. When the device restarts, it reads the seed from the file and uses the XOR function to compare the stored seed with the new seed. To generate a message key, the BlackBerry Device Service performs the following actions: Retrieves random data from multiple sources for the seed, using a technique that the BlackBerry Device Service derives from the initialization function of the ARC4 encryption algorithm 2. Uses the random data to reorder the contents of a byte state array The BlackBerry Device Service requests bits of randomness from the Microsoft Cryptographic API to increase the randomness of the data.
Adds the byte state array into the ARC4 algorithm to further randomize the byte state array 4.

When the BlackBerry Device Service restarts, it reads the seed from the file and uses the XOR function to compare the stored seed with the new seed. A VPN provides an encrypted tunnel between a device and your organization s network. The device can use the VPN client to authenticate with a VPN concentrator, which acts as the gateway to your organization's network. It creates an encrypted tunnel between the device and VPN concentrator that the device and your organization's network can use to communicate.
For more information about configuring VPN profiles, visit docs. For more information about protecting a work Wi-Fi network, see the documentation from your organization s Wi-Fi solution provider. After the device receives the sensitive Wi-Fi information, the device encrypts the encryption keys and passwords and stores them in flash memory.
You can help protect the sensitive Wi-Fi information in the BlackBerry Configuration Database using access controls and configuration settings. BES 10 comprises three services: If you're only planning on managing BlackBerry devices you'll only need to install the first two, as UDS adds tools for managing Android and iOS devices. One thing we noticed while installing our copy was that the licence keys we were sent didn't match what the software was asking for — or so we initially thought.
You may have to click forward and back a couple of times in the setup app to ensure your chosen ports don't conflict. At the same time, the device will begin to synchronize. Once the initial synchronization is complete, the device will display: Activation is Complete.
