18
Q

Three types of Authentication are:

A

Open System - No authentication Shared Key Authentication - authentication through shared key (pw) Centralized Authentication - Authentication through something like RADIUS

19
Q

Assocation vs Authentication

A

Association is the act of connecting; Authentication is the act of identifying the client.

20
Q

Spectrum Analyzer

A

Verifies wireless quality, detects rogue access points and detects attacks

21
Q

Directional Antenna

A

Signals in one direction; Yagi antenna is a type

22
Q

Omnidirectional Antenna

A

Signals in all directions

23
Q

WEP

A

Wired Equivalent Privacy - Encryption: RC4. IV Size: 24 bits. Key Length: 40/104. Integrity Check: CRC-32

24
Q

WPA

A

Wi-Fi Protected Access - Encryption: RC4 + TKIP IV Size: 48 bits. Key Length: 128 bits. Integrity Check: Michael/CRC-32

25
Q

WPA2

A

Encryption: AES-CCMP IV Size: 48 bits Key Length: 128-bits Integrity Check: CBC-MAC (CCMP)

26
Q

WPA2 Enterprise vs WPA2 Personal

A

Enterprise: Can tie an EAP or RADIUS server into authentication. Personal: Uses a pre-shared key to authenticate.

27
Q

Message Integrity Code (MIC)

A

Hashes for CCMP to protect integrity.

28
Q

Cipher Block Chaining Message Authentication Code (CBC-MAC)

A

Integrity process of WPA2

29
Q

WIGLE

A

Tool for network discovery that can map for wireless networks

30
Q

NetStumbler

A

Tool for network discovery

31
Q

Kismet

A

Wireless packet analyzer/sniffer that can be used for discovery. Works passively and can detect access points.

32
Q

NetSurveyor

A

Tool for Windows that does network discovery

33
Q

pcap vs libcap

A

pcap - driver library for Windows libcap - Drivery library for Linux

34
Q

Rogue Access point

A

Places an access point controlled by an attacker

35
Q

A

Rogue AP with a SSID similar to the name of a popular network

36
Q

Honeyspot

A

Fakinga well known hotspot with a rogue AP

37
Q

Ad Hoc Connection Attack

A

Connecting directly to another phone via ad-hoc network. User must accept connection

38
Q
