Protecting stored data

Protecting stored messages on the messaging server

The IBM Lotus Domino server and the Microsoft Exchange server perform all message storage and specific user

data storage in their environments. In the Novell GroupWise server environment, the Post-Office Agent where a

user’s messaging account resides stores messages and user data.

Storing message and user data in IBM Lotus Domino databases

The BlackBerry Enterprise Server creates and uses the following IBM Lotus Domino databases to manage

BlackBerry device messages:

Database Message storage method

BlackBerry state

• stores an entry that establishes a connection between each original message in a

user’s IBM Lotus Notes Inbox and the same message on that user’s BlackBerry

device

Note: Each BlackBerry user has a uniquely named BlackBerry state database.

BlackBerry profiles

• stores important configuration information for each user, including the

BlackBerry device identification information and master encryption key

• stores a link to a user’s BlackBerry state database and stores other information

that the BlackBerry Enterprise Server uses to manage the flow of messages to

and from the BlackBerry device

IT policy signing and storage on the BlackBerry device

An IT policy is a collection of one or more IT policy rules. An IT Admin command is a function that you can send

wirelessly to immediately control access to or change ownership information on the BlackBerry device.

After the BlackBerry Enterprise Server installation process creates the BlackBerry configuration database, the

BlackBerry Enterprise Server generates a unique private and public key pair to authenticate the IT policy and the

IT Admin commands, and digitally signs the Default IT policy before automatically sending it and the IT policy

public key to the BlackBerry device.

The BlackBerry device stores the digitally signed IT policy and the IT policy public key in the NV store in flash

memory, binding the IT policy to that particular BlackBerry device. The NV store persists in flash memory and can

only be overwritten by the BlackBerry device operating system. Third-party application code cannot write to the

NV store.

The BlackBerry Enterprise Server stores the IT policy private key in the BlackBerry configuration database. The

BlackBerry Enterprise Server uses the IT policy private key to sign all IT policy packets that it sends to the

BlackBerry device. The BlackBerry device uses the IT policy public key in the NV store to authenticate the digital

signature on the IT policy.

Application password encryption and storage on the BlackBerry device

A user can use the Password Keeper tool to create and store all of the passwords that they might use to gain

access to applications and web sites on the BlackBerry device. This means that a user is required to remember

only the Password Keeper master password to retrieve all of their stored passwords.
