How the BlackBerry Enterprise Solution protects connections between a BlackBerry device and the Internet or intranet
A user can use the BlackBerry® Browser and BlackBerry Java® Applications on a BlackBerry device to access the Internet and your organization’s intranet. The BlackBerry Browser and BlackBerry Java Applications can accept and respond to push requests from push applications. The BlackBerry Browser and BlackBerry Java Applications use the BlackBerry MDS Connection Service to access the Internet and your organization's intranet.
To access data on the Internet or your organization’s intranet, the BlackBerry MDS Connection Service uses HTTP, TCP/IP, and the BlackBerry MDS security protocol. The BlackBerry MDS security protocol is a Research In Motion® proprietary protocol that is designed to protect messages that the BlackBerry device sends using the BlackBerry MDS Connection Service. The BlackBerry MDS Connection Service and BlackBerry device use BlackBerry transport layer encryption to help protect your organization’s applications and the Internet data that a user receives on the BlackBerry device.
