IV Attack
Attackers cracking the WEP initialization vector by examining its repeats
Temporal Key Integrity Protocol (TKIP)
Placed a 128-bit wrapper around the WEP encryption with a key
Wireless Markup Language (WML)
A smaller version of HTML used by WAP
Gap in the WAP
The security concern that exists when converting between WAP (Wireless Application Protocol) and SSL/TLS and exposing plain text.
WPA Features
- RC4 with TKIP
- Compatible with older devices
WPA2 Features
- CCMP
- Not compatible with older devices
Counter Mode with Cipher Block Chaining Message Authentication Code Protocol (CCMP)
128-bit AES encryption with a 48 bit initialization vector
Wireless Application Protocol (WAP)
A data transmission standard that is meant to be like TCP/IP for wireless devices.
Wireless TLS
- Provides authentication, encryption, and data integrity for wireless devices.
- Supports wireless devices that don’t have extremely powerful processors
Wireless Session Protocol (WSP)
Manages the session info and connection between the devices
Wireless Transaction Protocol (WTP)
Provides services similar to TCP and UDP for WAP
Wireless Datagram Protocol (WDP)
Provides the common interface between devices
Transceiver
Transmitter/receiver, AKA a wireless access point
What portion of the RF spectrum do wireless technologies use?
Microwave
All antennas are rated in terms of _______.
Gain value
Captive Portal
Requires users to agree to some condition before they use the network.
Extensible Authentication Protocol (EAP)
Provides a framework for authentication that is often used with wireless networks
Wi-Fi Protected Setup (WPS)
EAP message(s) that require some sort of authentication to join the network
