provides for security enhancements to the wireless standard with focus on authentication WPA2 the name given to it by the WiFi Alliance
- 11n
pg. 170
most popular. speeds of up to 600 Mbps
Wired Equivalent Privacy
pg.171
wireless protocol designed to provide a privacy equivalent to that of a wired network
Wireless Application Protocol
pg.172
data transmission standard adopted by many manufacturers
Wireless Transport Layers Security
pg.173
the security layer of the Wireless Application Protocol. Provides authentication, encryption, and data integrity for wireless devices
Anonymous Authentication
pg.174
allows anyone to connect to the wireless portal
Server Authentication
pg.174
requires the workstation to authenticate against the server
Two-Way (Client and Server) Authentication
pg.174
requires both ends of the connection to authenticate to confirm validity
Wireless Session Protocol
pg.175
WSP manages the session information and connection between the devices
Wireless Transaction Protocol
pg.175
provides services similar to TCP and UDP for WAP
Wireless Transport Layer Security
pg.175
WTLS is the security layer of WAP
Wireless access pount
pg.175
is a low power transmitter/receiver also known as a transceiver which is strategically placed for access
Antenna Placement
pg.177
crucial in allowing clients to reach the access point
Omnidirectional Antenna
pg.178
provides a 360-degree pattern and an even signal in all directions
Directional antenna
pg.178
force the signal in one direction and can cover a greater distance with a stronger signal
MAC Filtering
pg.178
admin uses this utility to keep unwanted devices from joining the network by compiling a list of MAC addresses and giving access to ones on the list
Captive Portal
pg.180
requires users to agree to some condition before they use the network or internet
extensible Authentication Protocol
pg.181
provides a framework for authentication that is often used with wireless network
Lightweight Extensible Authentication Protocol
pg.182
Created by Cisco, lacks windows support, requires mutual authentication to improve security
Protected Extensible Authentication Protocol
pg.182
more establishes an encrypted channel between the server and the client
Site Survey
pg.189
initially meant determining whether a proposed location was free from interference
involves listening in on an existing wireless network using commercially available tools
War Driving
pg.185
refers to driving around town with a laptop looking for APs are communicate with\
Jamming
pg.185
the intent to jam the signal and keep the legitimate devices from communicating
