Plan your network architecture and design your security policies to help manage the risk of malware attacks. When you plan and set up your corporate network, you should set security policies to protect the network components, which might have many connections to the Internet and to external systems, as well as network clients such as BlackBerry devices.
Consider separating your corporate network infrastructure into digital zones, or segments, separated by firewalls, and restricting internal and external user access to those zones. You might require multiple security products and methods to protect each gateway from one section of your corporate network to another and to and from the Internet.
