Security Technical Overview

Security measure

By default, the discoverable mode option on BlackBerry

devices is turned off. The devices are not visible to other

Bluetooth enabled devices. A BlackBerry device never

enters into discoverable mode unless the user turns on that

feature.

You can set the Limit Discoverable Time IT policy rule to True

to allow users to turn on the discoverable mode option for

2 minutes only.

You can use the Disable Bluetooth IT policy rule to control

the Bluetooth wireless transceiver on BlackBerry devices.

By default, the Bluetooth wireless transceiver on BlackBerry

devices is turned off.

Users must request connections between their BlackBerry

devices and other Bluetooth enabled devices. They must

type a password called a passkey, which is a shared secret

key, to complete a connection or pairing with another

Bluetooth enabled device. A user's passkey must be

between one and 16 characters long, and it is dependent on

the target peripheral device.

Users can specify whether their BlackBerry devices use a

passkey to encrypt data that the users send over a Bluetooth

connection. You can use the Require Encryption IT policy

rule to require that Bluetooth enabled BlackBerry devices

use encryption over all Bluetooth connections.

When BlackBerry devices try to pair with other Bluetooth

enabled devices, the BlackBerry devices request a

combination key for authentication. The combination key is

unique to a BlackBerry device and the Bluetooth enabled

device that it is paired with.

The BlackBerry devices prompt the users each time that

other Bluetooth enabled devices try to connect to them.

Managing Bluetooth enabled BlackBerry devices

Benefit

Potential users with malicious intent cannot locate

BlackBerry devices easily and compromise them.

The BlackBerry devices are discoverable for a very limited

time to allow pairing with another device.

When the Bluetooth wireless transceiver is turned off,

Bluetooth wireless technology is not operational on the

BlackBerry devices, and the devices are not open to

malicious use of their Bluetooth technology.

Users are aware of attempts to connect or pair with

Bluetooth enabled devices because their BlackBerry devices

prompt them for a passkey.

Communication over the Bluetooth connection is protected.

Combination keys are designed to prevent the interception

of wireless communication between two devices by a third

device that was previously paired with one of the devices.

BlackBerry device users can decline connection requests

from Bluetooth enabled devices.
