802.11a uses frequencies in the _______________.

Back 8

5 GHz band

Front 9

The standard for wireless local area networks is called _______________.

Back 9

IEEE 802.11

Front 10

802.1g uses frequencies in the _______________.

Back 10

2.4 GHz Band

Front 11

Why does WTLS support short key lengths?

Back 11

WTLS has to support devices with low processor power and limited RAm

Front 12

Why should wireless have strong two-way authentication?

Back 12

Because wireless is especially susceptible to a man-in-the-middle attack

Front 13

Why is 802.11 wireless more of a security problem than any other type of network?

Back 13

It provides access to the physical layer of Ethernet without needing physical access to the building

Front 14

Bluebugging can give an attacker what?

Back 14

Total control over a mobile phone

Front 15

How does 802.11n improve network speed?

Back 15

A) Wider bandwidth

C) Multiple-input multiple-output (MIMO)

Front 16

WTLS ensures integrity through what means?

Back 16

Message authentication codes

Front 17

WEP has used an implementation of which of the following encryption algorithms?

Back 17

RC4

Front 18

How are the security parameters of WTLS chosen between two endpoints?

Back 18

The WTLS handshake determines what parameters to use

Front 19

What is bluejacking?

Back 19

Sending an unsolicited message via Bluetooth

Front 20

Why is it important to scan your own organization for wireless?

Back 20

It can detect rogue access points

Front 21

While the SSID provides some measure of authentication, why is it not very effective?
