Are wireless networks secure?
Overall, conventional wisdom holds that wireless networks are now “secure enough” to use in the vast majority of homes, and many businesses. Security features like 128-bit WEP and WPA can scramble or “encrypt” network traffic so that its contents can not easily be deciphered by snoopers. Likewise, wireless routers and access points (APs) incorporate access control features such as MAC address filtering that deny network requests from unwanted clients. The better a wireless network is administered, the more secure it becomes.
