Which technology is predominately used for contactless payment systems?
wireless local area network (WLAN)
Bluetooth
near field communication (NFC)
Temporal Key Integrity Protocol (TKIP)
Bluetooth falls under the category of ______________.
local area network (LAN)
short area network (SAN)
paired-device network (PDN)
personal area network (PAN)
Which of these IEEE WLANs has the highest data rate?
802.11b
802.11n
802.11g
802.11ac
Which of these technologies is NOT found in a wireless broadband router?
wireless probe
router
firewall
access point
Why is a rogue AP a security vulnerability?
It uses the weaker IEEE 802.15.ax protocol.
It allows an attacker to bypass many of the network security configurations.
It requires the use of vulnerable wireless probes on all mobile devices.
It conflicts with other network firewalls and can cause them to become disabled.
Which of these is NOT a risk when a home wireless router is not securely configured?
An attacker can steal data from any folder with file sharing enabled.
Usernames, passwords, credit card numbers, and other information sent over the WLAN could be captured by an attacker.
Only 50 percent of the packets will be encrypted.
Malware can be injected into a computer connected to the WLAN.
Which of these Wi-Fi Protected Setup (WPS) methods is vulnerable?
PIN method
push-button method
piconet method
NFC method
If Cora tries to access a free public Wi-Fi at a local coffee shop that requires her to first agree to an Acceptable Use Policy (AUP) before continuing, what type of AP has she encountered?
web-based
captive portal
rougue
internet content filter
What is the unauthorized access of information from a wireless device through a Bluetooth connection called?
bluejacking
bluesnarfing
Bluetooth snatching
Bluetooth spoofing
The primary design of a(n) ________ is to capture the transmissions from legitimate users.
rogue access point
WEP
evil twin
Bluetooth grabber
Which of these is a vulnerability of MAC address filtering?
The user must enter the MAC.
MAC addresses are initially exchanged between wireless devices and the AP in an unencrypted format.
APs use IP addresses instead of MACs.
Not all operating systems support MACs.
Which of these is NOT a limitation of turning off the SSID broadcast from an AP?
Users can more easily roam from one WLAN to another.
The SSID can easily be discovered, even when it is not contained in beacon frames, because it still is transmitted in other management frames sent by the AP.
Turning off the SSID broadcast may prevent users from being able to freely roam from one AP coverage area to another.
Some versions of operating systems favor a network that broadcasts an SSID over one that does not.
What is the primary weakness of wired equivalent privacy (WEP)?
It functions only on specific brands of APs.
Its usage creates a detectable pattern.
It slows down a WLAN from 104 Mbps to 16 Mbps.
Initialization vectors (IVs) are difficult for users to manage.
WPA replaces WEP with _________.
WPA2
Temporal Key Integrity Protocol (TKIP)
Cyclic Redundancy Check (CRC)
Message Integrity Check (MIC)
A preshared key (PSK) of fewer than __________ characters may be subject to an attack if that key is a common dictionary word.
20
32
48
64
A WEP key that is 128 bits in length ____________.
has an initialization vector (IV) that is the same length as a WEP key of 64 bits
cannot be cracked because it is too long
cannot be used on access points that use passphrases
is less secure than a WEP key of 64 bits because shorter keys are stronger
AES-CCMP is the encryption protocol standard used in _________.
Bluetooth
WPA2
IEEE 802.11
WPA
What is the Extensible Authentication Protocol (EAP)?
a framework for transporting authentication protocols
a subset of WPA2
the protocol used in TCP/IP for authentication
