For instance, with the individual components of a home alarm system made available wireless, a home security system can now be spread out further without wires running through the home or business. A home security system can now protect a home on the outside perimeter. Using these new wireless sensors, a home or business can now be completely surrounded by a wall of security.

Although wireless technology offers significant benefits, they also provide security challenges especially in the retail industry. Merchants that store, process, or transmit credit card information through retail stores, mail order, telephone order, and e-commerce should be aware of wireless threats which make up a significant part in the Payment Card Industry (PCI) compliance and defend against them.

These risks can compromise a retailer's network, resulting in a loss of customer information, audits and penalties. For instance, outsiders can try to profit by releasing the retailer’s confidential information over unsecured wireless links and then selling or using it. Hackers may also steal the data directly.

Basically, there are two security risks associated with wireless technology which must be prevented:
• Connections to neighboring wireless LAN networks
• Outsiders connecting to your network via a wireless LAN
