  • Page 67: Chapter 8: Wireless Security

    Wireless-G VPN Broadband Router Appendix B: Wireless Security A Brief Overview Whenever data - in the form of files, emails, or messages - is transmitted over your wireless network, it is open to attacks. Wireless networking is inherently risky because it broadcasts information on radio waves. Just like signals from your cellular or cordless phone can be intercepted, signals from your wireless network can also be compromised.
  • Page 68 Wireless-G VPN Broadband Router But even WEP has its problems. WEP's encryption algorithm is referred to as "simple", which also means "weak", because the technology that scrambles the wireless signal isn't too hard to crack for a persistent hacker. There are five common ways that hackers can break into your network and steal your bandwidth as well as your data.
  • Page 69 Wireless-G VPN Broadband Router Active Attacks Hackers use Active Attacks for three purposes: 1) stealing data, 2) using your network, and 3) modifying your network so it's easier to hack in the next time. In an Active Attack, the hacker has gained access to all of your network settings (SSID, WEP keys, etc.) and is in your network.
  • Page 70 Wireless-G VPN Broadband Router examples below, your implementation and administration of network security measures is the key to maximizing wireless security. No preventative measure will guarantee network security but it will make it more difficult for someone to hack into your network. Often, hackers are looking for an easy target. Making your network less attractive to hackers, by making it harder for them to get in, will make them look elsewhere.
  • Page 71 Wireless-G VPN Broadband Router There are a few things you can do to make your SSID more secure: a. Disable Broadcast b. Make it unique c. Change it often Most wireless networking devices will give you the option of broadcasting the SSID. This is a option for convenience, allowing anyone to log into your wireless network.
  • Page 72 Wireless-G VPN Broadband Router not completely secure. One piece of information still not encrypted is the MAC address, which hackers can use to break into a network by spoofing (or faking) the MAC address. Programs exist on the Internet that are designed to defeat WEP. The best known of these is AirSnort. In about a day, AirSnort can analyze enough of the wireless transmissions to crack the WEP key.
