WIDS - wireless intrusion detection system (A system typically implemented on an existing wireless LAN infrastructure which receives wireless transmitted packets, analyzes the packets, correlates the packets against existing IT policy standards, and alerts the WIDS administrator if there is a violation. A WIDS may be simply a workstation with an antenna running a specialized sniffing application.)
Wi-Fi - Wireless Fidelity (generic term for a wireless connection - wireless network products/certification standard)
WiMAX - Worldwide Interoperability for Microwave Access (A wireless connection, intended to replace Wi-Fi (wireless fidelity) with a high-performance, end-to-end Internet network architecture with a much stronger and robust geographically-based system covering a much larger physical area than Wi-Fi covers. Its technical specifications are based on the IEEE 802.16 (Institute of Electrical and Electronics Engineers). Since the WiMAX connection is considered highly reliable and capable of bypassing local telephone line service providers, it has been adopted by some cities for use by emergency services, such as police, fire, and ambulance, and also by some industries for use in large industrial complexes, such as chemical plants, oil refineries, and major manufacturing plants covering large-scale physical areas.)
WIPO - World Intellectual Property Organization (United Nations (UN) agency which oversees international intellectual property rights efforts, involving the copyright, patents, and trademark areas and disputes.)
WIPS - wireless intrusion prevention system (A system typically implemented on an existing wireless LAN infrastructure which receives wireless transmitted packets, analyzes the packets, correlates the packets against existing IT policy standards, and alerts the WIPS administrator if there is a violation. A WIPS may be simply a workstation with an antenna running a specialized sniffing application.)
WISP - Wireless Internet Service Provider (wireless broadband Internet provider)
WISPA - Wireless Internet Service Providers Association (wireless provider organization)
WLAN - wireless local area network (A network which connects network components within a local area, such as a building or small area, using wireless technology, such as cellular radio transmitters, receivers, and transceivers, where several user workstations connect using Wi-Fi to an access point installed in the room.)
WMA - Windows Media Audio (format for compressed music files)
WMAN - wireless metropolitan area network (A wireless network covering a very large geographic area, such as a city, that connects groups of smaller networks or connects directly to end users, which utilizes radio transmitters and receivers to communicate to wired LANS through access points or directly to wireless endpoints.)
WMD - weapon(s) of mass destruction (chemical, biological, radiological, and nuclear weapons that can cause damage, destruction, or contamination over a wide area, or inflict sickness, death, or injury on a large number of people)

WORM - Term for a self-contained malware program capable of replicating itself and spreading to multiple systems.
WOT - web of trust (tool for determining if a web page/site is safe)
WPA - Wi-Fi Protected Access (An encryption standard for wireless which uses/complies with AES (Advanced Encryption Standard) technology. WPA is considered less vulnerable than Wired Equivalent Privacy (WEP) encryption.)

WPF - Windows Presentation Foundation (developer framework)
WPS - Wi-Fi Protected Setup (An automated and semi-automated process to set up a secure wireless connection for a wireless network at the time a wireless device is connected to a wireless access point (WAP) by pushing a button to enter a WPS personal identification number (PIN). The PIN was used as the network's secure WPA (Wi-Fi Protected Access) key. WPS was found to be ineffective for security, since the PIN password could be identified by a brute-force attack.)
