networks. When introduced in 1999, WEP was intended to provide confidentiality comparable to that of a traditional
wired network (Wikipedia).
Wi-Fi
Wi-Fi is an acronym for Wireless Fidelity. It is meant to be used generically when referring of any type of 802.11
network, whether 802.11b, 802.11a, dual-band, etc. The term is promulgated by the Wi-Fi Alliance.
WPA
WPA is an acronym for Wi-Fi Protected Access. It was created in response to several serious weaknesses researchers
had found in the previous system , Wired Equivalent Privacy (WEP). WPA implements the majority of the IEEE 802.11i
standard, and was intended as an intermediate measure to take the place of WEP while 802.11i was prepared. WPA is
specifically designed to also work with pre-WPA wireless network interface cards (through firmware upgrades), but not
necessarily with first generation wireless access points. WPA2 implements the full standard, but will not work with
some older network cards (Wikipedia).
WPA-PSK
WPA-PSK is an acronym for Wi-Fi Protected Access - Pre Shared Key. WPA was designed to enhance the security of
wireless networks. There are two flavors of WPA: enterprise and personal. Enterprise is meant for use with an IEEE
802.1X authentication server, which distributes different keys to each user. Personal WPA utilizes less scalable
'pre-shared key' (PSK) mode, where every allowed computer is given the same passphrase. In PSK mode, security
depends on the strength and secrecy of the passphrase. The design of WPA is based on a Draft 3 of the IEEE 802.11i
standard (Wikipedia)
WPA-Radius
WPA-Radius is an acronym for Wi-Fi Protected Access - Radius (802.1X authentication server). WPA was designed to
enhance the security of wireless networks. There are two flavors of WPA: enterprise and personal. Enterprise is meant
for use with an IEEE 802.1X authentication server, which distributes different keys to each user. Personal WPA utilizes
less scalable 'pre-shared key' (PSK) mode, where every allowed computer is given the same passphrase. In PSK
mode, security depends on the strength and secrecy of the passphrase. The design of WPA is based on a Draft 3 of
the IEEE 802.11i standard (Wikipedia)
WPS
WPS is an acronym for Wi-Fi Protected Setup. It is a standard for easy and secure establishment of a wireless home
network. The goal of the WPS protocol is to simplify the process of connecting any home device to the wireless
network (Wikipedia).
WRED
WRED is an acronym for Weighted Random Early Detection. It is an active queue management mechanism that
provides preferential treatment of higher priority frames when traffic builds up within a queue. A frame's DP level is
used as input to WRED. A higher DP level assigned to a frame results in a higher probability that the frame is dropped
during times of congestion.
