Recently two researchers found one of the wifi encrypion standards which was previously not cracked can be overcome when used in conjuction with a feature which improves VOIP using a wifi network. This is a simplified explanation, of course, and without going to extreme detail about the various encryption standards it can now be said a wifi connection may not be safe when using WEP and WPA/WPA2 (TKIP).

Unless you are using a software or hardware package which addresses your security issues, WiFi.com recommends setting up your network using the Advanced Ecryption Standard (AES). If someone really wants to get into your network, they will do it. However, considering the US government uses this standrad for their own networks and it is the b est one can get at this time, you should feel relatively secure using AES for your wifi network.

When it comes to the 802.11 standard (WiFi), there are two types of security, which can be deployed on the wireless network. The most common and least secure method is Wired Equivalent Privacy (WEP) and the much more secure Wi-Fi Protected Access (WPA). It is important to note: Independent research conducted by wifi.com staff indicates better than 50% of home-based wireless networks and 40% of wifi hotspot providers do not deploy security measures.

For home-based and most other consumer-grade wireless networks, security is controlled at the access point or router. The current security settings on wifi-capable access points are; none, WEP, WPA, and WPA2. The key difference between WPA and WPA2 is the latter applies an Advanced Encryption Standard (AES), which has been adopted by the U.S. government.

In general WEP security will keep the average person from using your network. However, in August of 2001 a published article explained how the WEP encryption can be attacked and the passkey recovered in about 10 minutes time. Thus, if someone really wants in, they can gain access to the network and ultimately, your computer.

When securing a home network, wifi.com recommends using the WPA2 (AES) option. With the adoption of the next 802.11 standard (802.11n) the creation of a secure environment using WPA2 (AES) will become easier for the end user.
