Wireless Equivalency Protocol (WEP) has been one of the hottest topics in Irish news over the last few days. One of the leading providers of DSL in Ireland has supplied users with wireless routers protected using WEP. What made this newsworthy is that it has emerged that the WEP keys used to encrypt the network traffic and to control access to a private network were generated using the (Service Set Identifier) SSID. The algorithm used to generate the encryption keys has been analyzed and a tool is freely available which allows anyone within range of the router to trespass on a wireless network that has been secured using the default settings.
The DSL provider and media reports are advising customers that if they change their WEP keys, they will be safe from any trespassers or malicious attackers trying to get onto their network. While it is true changing the default WEP settings will mitigate this particular attack it will not make your wireless network secure.
