Exam 18: Wireless Network Security

the function of the __________ is to on transmission assemble data into a frame, on reception disassemble frame and perform address recognition and error detection, and govern access to the LAN transmission medium.

An __________ is a set of one or more interconnected BSSs and integrated LANs that appear as a single BSS to the LLC layer at any station associated with one of these BSSs.

the layer of the IEEE 802 reference model that includes such functions as encoding/decoding of signals and bit transmission/reception is the _________ .

Wireless networks, and the wireless devices that use them, introduce a host of security problems over and above those found in wired networks.

the PMK is used to generate the _________ which consists of three keys to be used for communication between a StA and AP after they have been mutually authenticated.

the first 802.11 standard to gain broad industry acceptance was _________.

Derived from the GMK, the _________ is used to provide confidentiality and integrity protection for multicast/broadcast user traffic.

MAC spoofing occurs when an attacker is able to eavesdrop on network traffic and identify the MAC address of a computer with network privileges.

the _________ is used to ensure the confidentiality of the GtK and other key material in the 4-Way Handshake.

the smallest building block of a wireless LAN is a __________ which consists of wireless stations executing the same MAC protocol and competing for access to the same shared wireless medium.

the actual method of key generation depends on the details of the authentication protocol used.

the __________ function is the logical function that determines when a station operating within a BSS is permitted to transmit and may be able to receive PDUs.

In a(n) __________ situation, a wireless device is configured to appear to be a legitimate access point, enabling the operator to steal passwords From legitimate users and then penetrate a wired network through a legitimate wireless access point.

the __________ layer is responsible for detecting errors and discarding any frames that contain errors.

the __________ layer keeps track of which frames have been successfully received and retransmits unsuccessful frames.

A __________ is any device that contains an IEEE 802.11 conformant MAC and physical layer.

A __________ attack occurs when an attacker continually bombards a wireless access point or some other accessible wireless port with various protocol messages designed to consume system resources.

the use of 802.1X cannot prevent rogue access points and other unauthorized devices from becoming insecure backdoors.

Sensors and robots are not vulnerable to physical attacks.

the __________ is the information that is delivered as a unit between MAC users.
