Exam 7: Wireless Network Security

IEEE 802.11 defines seven services that need to be provided by the wireless LAN to achieve functionality equivalent to that which is inherent to wired LANs.

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

To certify interoperability for 802.11b products an industry consortium named the __________ was formed.

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

The master session key is also known as the __________ key

The IEEE 802.11 protocol stack consists of the logical link control layer, the medium access control layer, and the _________ layer.

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

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

Handheld PDAs pose a security risk in terms of both eavesdropping and spoofing.

The MPDU exchange for distributing pairwise keys is known as the _________ which the STA and SP use to confirm the existence of the PMK, to verify the selection of the cipher suite, and to derive a fresh PTK for data sessions.

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

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

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

____________ can occur when a company's wireless LAN or wireless access points to wired LANs in close proximity and may create overlapping transmission ranges.A user intending to connect to one LAN may unintentionally lock on to a wireless access point from a neighboring network

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

The purpose of the discovery phase in the ___________ is for a 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

Security policies for mobile devices should assume that any mobile device will not be stolen or accessed by a malicious party.

In simple terms, the wireless environment consists of three components that provide point of attack: the endpoint, the ______________, and the access point.

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

__________ is the primary service used by stations to exchange MPDUs when the MPDUs must traverse the DS to get from a station in one BSS to a station in another BSS.
