BlackBerry Enterprise Solution Security

Controlling BlackBerry devices 39

Protecting third-party applications on the BlackBerry device

Java-based BlackBerry devices are designed to provide an open platform for third-party application

development. Using BlackBerry MDS Studio™ and the BlackBerry Java Development Environment (JDE), the

BlackBerry Enterprise Solution enables software developers to create wireless enterprise applications.

BlackBerry JDE developers can create more powerful, sophisticated applications than are possible with standard

Java™ 2 Platform Micro Edition (J2ME™). A third-party BlackBerry application can perform the following tasks:

• communicate and share persistent storage with other third-party BlackBerry applications

• interact with native BlackBerry applications

• access user data such as calendar appointments, email messages, and contacts

Note: RIM does not inspect or verify third-party applications.

Protecting BlackBerry devices against malicious applications

By default, Java-based BlackBerry devices can download third-party applications wirelessly using the BlackBerry

Browser. You can also send third-party applications to BlackBerry devices wirelessly, and install them on the

BlackBerry devices automatically.

The following security features of the BlackBerry JDE are designed to minimize any potential risk introduced by

adding third-party applications to the BlackBerry device and address security concerns that an open and flexible

framework for application development on the BlackBerry device might raise.

BlackBerry JDE security method Description

code signing

• RIM controls the use of APIs that include sensitive packages,

classes, or methods to prevent unauthorized, malicious applications

from accessing data on the BlackBerry device. Before you or a user

can run a third-party application that uses the RIM-controlled APIs

on the BlackBerry device, RIM’s signing authority system must use

public key cryptography to authorize and authenticate the

application code. The third-party application developer must visit

www.blackberry.com/developers/downloads/jde/api.shtml to

controlled APIs and use the BlackBerry Signature Tool that is a

component of the BlackBerry JDE to request, receive, and verify a

digital code signature from RIM for the application.

• Third party application developers who create controlled access

third-party APIs can act as a signing authority for those APIs. The

application developer can download and install the BlackBerry

Signing Authority Tool to enable other developers to register for

access to the application developer’s controlled APIs. Registered

developers can use their BlackBerry Signature Tool to request,

receive, and verify digital code signatures from the application

developer’s BlackBerry Signing Authority Tool for their

applications. See the BlackBerry Signing Authority Tool

Administrator Guide for more information.
