What is WEP?
WEP stands for Wired Equivalent Privacy, and is a security protocol for wireless networks. Due to known security flaws, WEP has since been superseded by WPA and WPA2. See also WPA.
How does WEP work?
The goal of WEP was to implement confidentiality on par with a wired network. WEP was once the most common type of security used on wifi networks and is still very common despite its well-documented flaws. As a result, many devices–routers, computers, and smartphones–still support the deprecated algorithm.
