managementforcomputerstoconnectanduseanetworkservice.Becauseofitsbroadsupport
andubiquitousnature,theRADIUSprotocolisoft enusedbyISPsandenterprisestomanage
accesstotheInternetorinternalnetworks,WLANs,andintegratede‐mailservices.
ServiceSetIdentifier (SS I D) 
NameofaWLAN.AllwirelessdevicesonaWLANmustusethesameSSIDtocommunicatewith
eachother.
SimpleNetworkManagement Protocol (S N MP) 
AnInternet‐standardprotocolformanagingdevicesonIPnetworks.
Sn oo p i n g
Passivelywatchinganetworkfordata,suchaspasswords,thatcanbeusedtobenefitahacker.
TemporalKeyIntegr ity Protocol ( T KI P) 
Anencryptionprotocolthatuses128‐bitkeys.Keysaredynamicallygeneratedanddistributedby
theauthenticationserver.TKIPregularlychangesandrotatesencryptionkeys,withanencryption
keyneverbeingusedtwice.
Transmission ControlProtocol/Internet Protocol ( T C P / I P) 
Aprotocolthatallowscommunicationsoverandbetweennetworks.TCP /IPisthebasisfor
Internetcommunications.
Weighted FairQueuing ( W F Q ) 
WFQservicesqueuesarebasedonpriorityandqueueweight.Queueswithlargerweightsget
moreservicethanqueueswithsmallerweights.Thishighlyefficientqueuingmechanismdivides
availablebandwidthacrossdifferenttrafficqueues.
WiredEquivalent Privacy ( W E P) 
SecurityprotocolthatprovidesaWLANwithalevelofsecurityandprivacycomparabletothatof
awiredLAN.WEPencryptsdatasentbetweenwiredandWLANstokeeptransmissionsprivate.
WirelessLocal‐AreaNetwork ( W L A N ) 
WLANsuseRFtechnologytosendandreceivedatawirelesslyinacertainarea.Thisletsusersina
smallzonesenddataandshareresourcessuchasprinterswithoutusingcablestophysically
connecteachcomputer.
Wi‐FiProtectedAccess(WPA ) 
AsubsetoftheIEEE802.11istandard.WPAappliesIEEE802.1xandExtensibleAuthentication
Protocol(EAP)toauthenticatewirelessclientsusinganexternalRADIUSdatabase.WPAuses
TemporalKeyIntegrityProtocol(TKIP),MessageIntegrityCheck(MIC),andIEEE802.1xtoencrypt
data.SeealsoWPA‐PSK(WPA‐Pre‐SharedKey).
Wi‐FiMultiMedia ( W MM) 
PartoftheIEEE802.11eQoSenhancementtotheWi‐Fistandardthatensuresqualityofservice
formultimediaapplicationsinWLANs.
WirelessClient Supp li c an t s 
Softwarethatrunsonanoperatingsystem,instructingthewirelessclienthowtouseWPA.
WPA‐Pre‐SharedKey ( W P A ‐ PS K ) 
WPA‐PSKrequiresasingle(identical)passwordenteredintoeachAccessPoint,wirelessgateway,
andwirelessclient.AclientisgrantedaccesstoaWLANifthepasswordsmatch.
