In the context of wireless network security, we hear a lot about WEP vs WPA, but these technologies are not widely understood, especially among attorneys.
WEP and WPA are two alternative ways to secure a wireless network from unauthorized interception, and WPA is more secure than WEP. In fact, researchers have reported consistently for several years that it is relatively easy to break into a WEP-secured wireless network. For that reason, as discussed further below, industry standards as well as regulators require that WPA (instead of WEP) be used to secure wireless networks that are used to transmit sensitive information such as credit card numbers. Nonetheless, many companies are still using WEP.
