Exam 24: Wireless Network Security

There are two types of keys: ________ used for communication between a STA and an AP and group keys used for multicast communication.

The unit of data exchanged between two peer MAC entities using the services of the physical layer is a(n) ____________.

The wireless access point provides a connection to the network orservice.

The function of the ________ layer is to control access to the transmission medium and to provide an orderly and efficient use of that capacity.

The transmission medium carries the radio waves for data transfer.

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.

______ is the recommended technique for wireless network security.

A system used to interconnect a set of basic service sets and LANs to create an extended service set is a _________.

The most significant source of risk in wireless networks in theunderlying communications medium.

Any device that contains an IEEE 802.11 conformant MAC andphysical layer is a basic service set.

The purpose of the authentication phase is to maintain backwardcompatibility with the IEEE 802.11 state machine.

A wireless client can be _______.

The principal threats to wireless transmission are disruption, _____________, and altering or inserting messages.

In most data-link control protocols, the data-link protocol entity isresponsible not only for detecting errors using the CRC, but forrecovering from those errors by retransmitting damaged frames.

Company wireless LANs or wireless access points to wired LANs inclose proximity may create overlapping transmission ranges.

The final form of the 802.11i standard is referred to as ________.

The two services involved with the distribution of messages within a DS are distribution and _________.

An example of a(n) __________ attack is one in which bogus reconfiguration commands are used to affect routers and switches to degrade network performance.

The MAC service data unit contains any protocol controlinformation needed for the functioning of the MAC protocol.

The wireless environment consists of three components that provide point of attack: the wireless client, the transmission medium, and the _________.
