Summary

Wireless networking by its nature requires more security than a wired networking technology, such as Ethernet. You can use some security methods , such as using a router and firewall to keep unauthorized users from gaining access to your network from the Internet. You can also use WEP to encrypt data over your wireless network. If you use a router, you can set up the router to only allow network adapters that you select to have access to your network. Finally, make sure each machine on your network has antivirus software installed, and be diligent in downloading up-to-date lists of circulating viruses, or your software will be of little use.
