How a BlackBerry device protects its operating system and the BlackBerry Device Software

Each time a user turns on a BlackBerry® device, specific components on the BlackBerry device automatically check the authenticity of the BlackBerry device operating system and the integrity of the BlackBerry® Device Software. The BlackBerry Device Software must pass these security checks before the user can run the BlackBerry Device Software and before the user can update the BlackBerry Device Software over the wireless network.
