Objective 3.5: Plan and Implement Security for Wireless Networks

 < Day Day Up > 



War driving is a hacker term for driving around with a Global Positioning System (GPS) device and a wireless LAN card taking note of locations with wireless access points. These wireless access points are locations where a wireless LAN has been implemented by an organization, but because the transmission area of the wireless LAN is greater than the boundaries of the organization’s building, the wireless LAN spills out into public areas such as streets and sidewalks. War drivers compile lists of such locations and post them on the Internet.

Without adequate security, a wireless network can be accessed by anyone with a wireless Ethernet card. People who download locations compiled by war drivers might just be looking for free access to the Internet to browse sites that might attract the attention of their Internet service provider (ISP) or other authorities, or they might be trying to gain access to a mail server to send junk e-mail messages, or even trying to access data stored on an organization’s network. An insecure wireless LAN is an easy target. If a wireless LAN is necessary at an organization, it needs to be secured. With the release of Windows XP Service Pack 1 and Windows Server 2003, Microsoft has included technology that can be used to secure wireless LANs. This technology can be used to secure wireless LANs so that they are inaccessible to unauthorized clients. If this technology is properly implemented, your organization’s wireless network will not end up listed somewhere on the Internet as a place where anyone can stroll up and gain access.
