Extending BlackBerry device messaging security 16

SMS and MMS messaging

SMS and MMS messaging are available on some BlackBerry devices. Supported BlackBerry devices can send

SMS and MMS messages over the wireless TCP/IP connection between them. The BlackBerry device does not

encrypt SMS and MMS messages.

Controlling unsecured messaging

You can control unsecured messaging (PIN, SMS, and MMS communication) in your organization using the

following IT policy rules:

IT policy rule Description

Allow External

Connections

This IT policy rule controls whether applications can initiate external connections

(for example, to WAP, SMS, MMS or other public gateways) on the BlackBerry

device.

Confirm on Send This IT policy rule requires a user to confirm that they wish to send the message

before sending an email message, PIN message, SMS message, or MMS message.

Disable Forwarding

Between Services

This IT policy rule prevents a user from forwarding or replying to a message using a

different BlackBerry Enterprise Server from the one that delivered the original

message. This IT policy rule also prevents using an email account to forward or reply

to a PIN message or reply to an email message with a PIN message.

Disable Peer-to-Peer

Normal Send

This IT policy rule prevents a user from sending plain text PIN messages when using

a secure messaging package, such as the S/MIME Support Package or the PGP

Support Package.

Turning off unsecured messaging

You can turn off unsecured messaging to make sure that all communication originating at the BlackBerry devices

in your organization travels through the enterprise messaging environment.

Scenario Description

turn off PIN messaging Set the Allow Peer-to-Peer Messages IT policy rule to False.

Note: When you turn off PIN messaging, users cannot send PIN messages from

the BlackBerry device; however, they can still receive PIN messages on their

BlackBerry devices.

turn off SMS messaging Set the Allow SMS IT policy rule to False.

turn off MMS messaging Set the Disable MMS IT policy rule to True.

Extending BlackBerry device messaging security

In addition to standard BlackBerry encryption, you can enable S/MIME technology or PGP technology to offer an

additional layer of security between the sender and recipient of an email or PIN message. Using either one of

these technologies enables sender-to-recipient authentication and confidentiality, and helps maintain data

integrity and privacy from the time that a user sends a message from the BlackBerry device until the message

recipient decodes and reads the message.

PGP Support Package

The PGP Support Package is designed to provide support for using OpenPGP (RFC 2440) message formatting on

the BlackBerry device to enable users who already send and receive PGP protected messages in OpenPGP

format using their computer email applications to send and receive PGP protected messages in that format using

their BlackBerry devices.
