Wireless Networking Chapter 14

Question 1

Define Transit Beam Forming

Answer 1

Beamforming is a technique that focuses a wireless signal towards a specific receiving device, rather than have the signal spread in all directions, like from a broadcast antenna. The resulting direct connection is faster and more reliable than it would be without beamforming.

Question 1

Define Extended Basic Service Set (EBSS)

Answer 1

A network consisting of multiple access points.

Question 2

Define IEE 802.11

Answer 2

Family of standards for wireless local area networks marketed as wifi

Question 3

Define Wireless Access Point (WAP)

Answer 3

Connects wireless network nodes to wireless or wired networks. Many WAPs are como devices that act as high speed hubs, switches, bridges, and routers all rolled into one

Question 4

Define Wired Equivalent Privacy (WEP)

Answer 4

Early wireless security protocol for wifi that uses the RC4 encryption algorithm. No longer used due to major security vulnerabilities.

Question 5

Define Wireless Protected Access (WPA)

Answer 5

Addresses weaknesses and acts as an upgrade to WEP. Offers security enhancements such as dynamic encryption key generations (keys are issues are issued on a per user/per session basis) an encryption key integrity checking feature, user authentication through the industry standard extensible authentication protocol (EAP), and other advanced features WEP lacks. Been replaced by WPA2

Question 6

Define Wireless Protected Access 2 (WPA2)

Answer 6

Consumer name for the IEEE802.11i standard and replacement for WPA protocol. Uses advanced encryption standard algorithm, making it much harder to crack then its predecessor.

Question 7

Define Wireless Protected Access 3 (WPA3)

Answer 7

Standard that is replacing WPA2, uses simultaneous authentication of equals (SAE), a key exchanged based on Diffie-Hellman that generates unique encryption keys between each client and WAP.

Question 8

Define Extensible Authentication Protocol (EAP)

Answer 8

Authentication wrapper that EAP compliant applications can use to accept one of many types of authentication, while EAP is a general purpose wrapper, its only uses is in wireless networks.
