Bluetooth
Radio Frequency ID (RFID)
Near field communication (NFC)
Which of these Bluetooth attacks involves accessing unauthorized information through a Bluetooth connection?
Bluesnarfing
Bluejacking
Bluecreeping
Bluestealing
Bluesnarfing
What is a difference between NFC and RFID?
NFC is based on wireless technology while RFID is not.
RFID is faster than NFC.
RFID is designed for paper-based tags while NFC is not.
NFC devices cannot pair as quickly as RFID devices.
RFID is designed for paper-based tags while NFC is not.
Which of these technologies is NOT found in a wireless router?
Access point
Router
Dynamic host configuration protocol (DHCP) server
Firewall
All of these are found
Why is a rogue AP a security vulnerability?
It uses the weaker IEEE 80211i protocol.
It conflicts with other network firewalls and can cause them to become disabled.
It allows an attacker to bypass network security configurations.
It requires the use of vulnerable wireless probes on all mobile devices.
It allows an attacker to bypass network security configurations.
Which of these is NOT a risk when a home wireless router is not securely configured?
Only a small percentage of the total traffic can be encrypted.
An attacker can steal data from any folder with file sharing enabled.
User names, passwords, credit card numbers, and other information sent over the WLAN could be captured by an attacker.
Malware can be injected into a computer connected to the WLAN.
Only a small percentage of the total traffic can be encrypted.
Which of these Wi-Fi Protected Setup (WPS) methods is vulnerable?
Push-button method
PIN method
Piconet method
NFC method
PIN method
Flavio visits a local coffee shop on his way to school and accesses its free Wi-Fi. When he first connects, a screen appears that requires him to first agree to an Acceptable Use Policy (AUP) before continuing. What type of AP has he encountered?
Captive portal
Web-based portal
Rogue portal
Authenticated portal
Captive portal
Which of the following is NOT a wireless peripheral protection option?
Update or replacing any vulnerable device
Switch to a more fully tested Bluetooth model
Install a network sensor to detect an attack
Substitute a wired device
Install a network sensor to detect an attack
The primary design of a(n) is to capture the transmissions from legitimate users.
rogue access point
WEP
evil twin
Bluetooth grabber
evil twin
Which of these is a vulnerability of MAC address filtering?
APs use IP addresses instead of MACs.
The user must enter the MAC.
MAC addresses are initially exchanged unencrypted.
Not all operating systems support MACs.
MAC addresses are initially exchanged unencrypted.
Which of these is NOT a limitation of turning off the SSID broadcast from an 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.
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.
Users can more easily roam from one WLAN to another.
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.
Its usage creates a detectable pattern.
WPA replaces WEP with .
WPA2
Temporal Key Integrity Protocol (TKIP)
cyclic redundancy check (CRC)
Message Integrity Check (MIC)
Temporal Key Integrity Protocol (TKIP)
Adabella was asked by her supervisor to adjust the frequency spectrum settings on a new AP. She brought up the configuration page and looked through the different options. Which of the following frequency spectrum settings would she NOT be able to adjust?
Frequency band
Channel selection
RFID spectrum
Channel width
RFID spectrum
