Exam 24: Wireless Network Security

The purpose of the discovery phase is for an STA and an AP to recognize each other,agree on a set of security capabilities,and establish an association for future communication using those security capabilities.

Two types of countermeasures are appropriate to deal with eavesdropping: signal-hiding techniques and ____________.

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

The lowest layer of the IEEE 802 reference model is the __________ layer.

______ is the recommended technique for wireless network security.

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

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

The security requirements are: confidentiality,integrity,availability,authenticity,and __________.

Like TKIP,CCMP provides two services: message integrity and ________.

The wireless access point provides a connection to the network or service.

The smallest building block of a wireless LAN is a ______.

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.

CRC is an error detecting code.

The transmission medium carries the radio waves for data transfer.

A ____________ attack involves persuading a user and an access point to believe that they are talking to each other when in fact the communication is going through an intermediate attacking device.

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

The specification of a protocol,along with the chosen key length,is known as a ___.

The wireless environment lends itself to a ______ attack because it is so easy for the attacker to direct multiple wireless messages at the target.

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

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