Placing the BlackBerry Enterprise Solution in a Segmented Network: BlackBerry Enterprise Server Version 4.0 and Later

Overview

Using a firewall, a person can separate a network or LAN into multiple components to create segmented network architecture. The firewall blocks data that is not destined for a particular segment, and might block all protocol ports except those that that segment specifically requires. Thus each segment contains filtered and isolated network traffic, which might improve the security and performance of the network. A particular department or a specific group of servers in an organization can use a segment of the corporate LAN while a bridge, router, or switch separates that segment from the rest of the corporate LAN. If the corporate security policies enforce the use of segmented network architecture, one can place the BlackBerry Enterprise Solution components in network segments.
