Wired Equivalent Privacy (WEP),part of the 802.11b standard,was developed to encrypt data traversing a wireless network.For some time,it gave many security professionals a false sense of security that wireless technology could be just as safe as wired networks.Unfortunately,WEP has been torn to shreds by security professionals,professors from major universities,and hackers who post ways to crack WEP encryption.Some argue that WEP is still better than no security at all,and when it's combined with the security of a virtual private network (VPN),they claim that WEP works well for home users or small businesses.Still,many saw a need for a better way to protect WLANs.
