Chapter 8: Wireless Network Security

Front 1

AES-CCMP:

Back 1

The encryption protocol standard for WPA2.

Front 2

bluejacking:

Back 2

An attack that sends unsolicited messages to Bluetooth-enables devices.

Front 3

bluesnarfing:

Back 3

An attack that accesses unauthorized information from a wireless device through a Bluetooth connection, often between cell phones and laptop computers.

Front 4

bluetooth:

Back 4

A Wireless technology that uses short-range radio frequency (RF) transmissions and provides for rapid ad hoc device pairings.

Front 5

evil twin:

Back 5

An AP setup by an attacker to mimic an authorized AP and capture transmissions, so a users device will unknowingly connect to this evil twin instead.

Front 6

extensible authentication protocol (EAP)

Back 6

A framework for transporting authentication protocols that defines the format of the messages.

Front 7

initialization vector(IV):

Back 7

A 24-bit value used in WEP that changes each time a packet is encrypted.

Front 8

Keystream attack (IV attack):

Back 8

A method of determining the key stream by analyzing two packets that were created from the same initialization vector (IV).

Front 9

Lightweight EAP(LEAP):

Back 9

A proprietary EAP method developed by Cisco systems requiring mutual authentication used for WLAN encryption using Cisco client software:

Front 10

Media Access Control(MAC) address filtering:

Back 10

A method for controlling access to a WLAN based on the devices MAC address

Front 11

preshared key(PSK)

Back 11

A key value that must be created and entered into both the access point and all wireless devices ("Shared") prior to ("pre") the devices communicating with the AP.

Front 12

Protected EAP (PEAP):

Back 12

An EAP method designed to simplify the deployment of 802.1x by using Microsoft Windows logins and passwords.

Front 13

rogue access point:

Back 13

An unauthorized AP that allows an attacker to bypass many of the network security configurations and opens the network and its users to attacks.

Front 14

Service Set identifier (SSID):

Back 14

The user-supplied network name of a WLAN; it can generally be alphanumeric from 2 to 32 characters.

Front 15

SSID broadcast:

Back 15

The transmission of the SSID from the access point to wireless devices.

Front 16

SSID broadcast:

Back 16

The transmission of the SSID from the access point to wireless devices.

Front 17

Temporal Key Integrity protocol (TKIP):

Back 17

A WPA encryption technology

Front 18

war chalking:

Back 18

The process of documenting and then advertising the location of wireless LANs for others to use. Wireless networks were identified by drawing on sidewalks or walls around the area of the network.

Front 19

war driving:

Back 19

Searching for wireless signals from an automobile or on foot using a portable computing device.

Front 20

Wi-Fi Protected Access(WPA):

Back 20

The original set of protections from the Wi-Fi alliance in 2003 designed to protect both present and future wireless devices.

Front 21

Wi-fi Protected Access 2(WPA2):

Back 21

The second generation of WPA security from the Wi-Fi alliance in 2004 to address authentication and encryption on WLANS.

Front 22

Wired Equivalent Privacy(WEP):

Back 22

An IEEE 802.11 security protocol designed to ensure that only authorized parties can view transmitted wireless information. WEP has significant vulnerabilities and is not considered secure.
