Wardriving is the act of searching for Wi-Fi wireless networks by a person in a moving vehicle using a portable device.
Web Application Firewall
According to the Web Application Security Consortium, a web application firewall (WAF) is an intermediary device, sitting between a web client and a web server, analysing messages at application layer for violations in the programmed security policy.
Change of the content (usually the main page) of a website with some messages by intruder or by virus.
Wi-Fi Protected Access (WPA)
Wi-Fi Protected Access (WPA) is a wireless security protocol designed to address and fix the known security issues in WEP. WPA provides users with a higher level of assurance that their data will remain protected by using Temporal Key Integrity Protocol (TKIP) for data encryption. 802.1x authentication has been introduced in this protocol to improve user authentication. WPA has been superseded by WPA2.
Wi-Fi Protected Access 2 (WPA2)
Wi-Fi Protected Access 2 (WPA2) is a wireless security protocol, based on IEEE 802.11i, in which only authorised users can access their wireless with the features of supporting stronger cryptography (Advanced Encryption Standard, AES), stronger authentication control (Extensible Authentication Protocol, EAP), key management, replay attack protection and data integrity.
Wi-Fi Protected Access 3 (WPA3)
Wi-Fi Protected Access 3 (WPA3) is a new wireless security standard built on WPA2 but brings new features to enhance Wi-Fi security for more robust authentication, enhanced cryptographic strength, while maintaining resiliency of mission critical networks.
Wired Equivalent Privacy (WEP)
Wired Equivalent Privacy Protocol (WEP) is a basic security feature of IEEE 802.11 standard that was intended to provide confidentiality over a wireless network by encrypting information sent over the network. After the key-scheduling flaw was found in the WEP, it is now considered to be fully broken because the WEP key can be cracked in minutes with the aid of automated tools.
A worm is a program that spreads over network. Unlike a virus, worm does not attach itself to a host program.
