2.5 Authentication and Security
Click“Authentication and Security”tab on the“Add Profile”page and
you can start configuring authentication. Please refer to the following
instructions.
WEP is short for Wired Equivalent Privacy, a security protocol for
WLANs defined in the 802.11b standard. WEP is designed to provide
the same level of security as that of a wired LAN. WEP aims to provide
security by encrypting data over radio waves so that it is protected as it
transmitted from one end point to another.
WPA is short for Wi-Fi Protected Access, a Wi-Fi standard that was
designed to improve upon the security features of WEP. The technology
is designed to work with existing Wi-Fi products that have been enabled
with WEP. It also provides strong data protection by using encryption
as well as strong access controls and user authentication. WPA utilizes
128-bit encryption keys and dynamic session keys to ensure your wireless
network's privacy and enterprise security.
WPA-PSK is short for Wi-Fi Protected Access-Pre-Shared Key. WPA-
PSK is basically an authentication mechanism in which users provide
some form of credentials to verify that they should be allowed access to a
network. This requires a single password entered into each WLAN node
(Access Points, Wireless Routers, client adapters, bridges). As long as the
passwords match, a client will be granted access to a WLAN. Encryption
mechanisms used for WPA and WPA-PSK are the same. The only
difference between the two is in WPA-PSK, authentication is reduced to a
simple common password, instead of user-specific credentials.
