Security Technical Overview
•
No Wi-Fi connection is available.
To open a link using the Bridge Browser, the tablet must be able to access the BlackBerry MDS Connection Service.
Running the Files application in work mode
When a BlackBerry PlayBook tablet runs the Files application in work mode, a BlackBerry PlayBook tablet user can
access the files that are stored on the media card that is inserted in the BlackBerry smartphone. The tablet opens
the files using work applications and classifies the files as work data.
If the user opens and updates files that are stored on the media card, the tablet does not store any content locally,
and encrypts any data it caches using XTS-AES-256 encryption.
Taking screen shots on a tablet
The BlackBerry PlayBook tablet allows a BlackBerry PlayBook tablet user to take a screen shot of the current
screen by holding the Volume Up key and Volume Down key at the same time.
The user can take screen shots when the tablet is running in personal mode only. The tablet saves screen shots in
the Camera application and displays them in the Photo viewer application. The tablet treats screen shots as
personal files.
The tablet prevents the user from taking screen shots of work data when a work application is open and unlocked.
When a tablet prevents a user from accessing work data or
work applications
A BlackBerry PlayBook tablet user can access work data and work applications when the BlackBerry PlayBook
tablet is connected to a BlackBerry smartphone. The tablet does not permit the user to access work data or work
applications when any of the following events occur:
•
User stops interacting with the tablet for a time period that is longer than the smartphone-timeout period
•
Tablet resets or loses power
•
Bluetooth connection to the smartphone closes
•
You or the user deletes all smartphone data
If one of these events occurs, the tablet locks all work applications and deletes the BlackBerry Bridge work key so
that local cache data is not recoverable.
If the user connects the tablet to another smartphone or the user types the smartphone password incorrectly
more times than the Set Maximum Password Attempts IT policy rule or the password option on the smartphone
permits, the tablet performs the following actions:
•
Deletes the work file system
•
Closes all work applications
•
Deletes the BlackBerry Bridge work key from the tablet memory
