246 McAfee Internet Security
worm
A self-replicating virus that resides in active memory and can send copies of itself through
e-mail. Worms replicate and consume system resources, slowing performance or halting
tasks.
WPA
(Wi-Fi Protected Access) A specification standard that strongly increases the level of data
protection and access control for existing and future wireless LAN systems. Designed to run
on existing hardware as a software upgrade, WPA is derived from, and is compatible with,
the IEEE 802.11i standard. When properly installed, it provides wireless LAN users with a
high level of assurance that their data remains protected and that only authorized network
users can access the network.
WPA-PSK
A special WPA mode designed for home users who do not require strong enterprise-class
security and do not have access to authentication servers. In this mode, the home user
manually enters the starting password to activate Wi-Fi Protected Access in Pre-Shared Key
mode, and should change the pass-phrase on each wireless computer and Access Point
regularly. See also WPA2-PSK and TKIP.
WPA2
An update to the WPA security standard, based on the 802.11i IEEE standard.
WPA2-PSK
A special WPA mode that is similar to WPA-PSK and is based on the WPA2 standard. A
common feature of WPA2-PSK is that devices often support multiple encryption modes (for
example, AES, TKIP) simultaneously, while older devices generally support only a single
encryption mode at a time (that is, all clients would have to use the same encryption
mode).
