Question 3

____ is considered to be the "heart and soul" of WPA security.

Accepted Answer

TKIP (Temporal Key Integrity Protocol) is considered to be the "heart and soul" of WPA security. It manages the encryption keys used for securing wireless networks and helps protect against types of attacks, such as replay attacks and unauthorized access. TKIP is used in conjunction with other WPA technologies, such as MIC (Message Integrity Check), to provide a more comprehensive security solution. PSK (Pre-Shared Key) and IV (Initialization Vector) are components of WPA, but not considered to be the heart and soul of the security.

Question 4

At the heart of a WIDS are ____; these devices, which can be either separate hardware devices or a standard access point operating in a special "scan" mode, monitor the airwaves to detect signals from rogue access points.

Accepted Answer

Wireless sensors are the devices that are at the heart of a Wireless Intrusion Detection System (WIDS). These sensors monitor the airwaves to detect signals from rogue access points. They may be separate hardware devices or a standard access point operating in a special "scan" mode. Captive portals, VPNs, and firewalls are not directly related to the monitoring of wireless networks for rogue access points.

Question 8

A ____ VPN is a user-to-LAN connection used by remote users.

Accepted Answer

Remote-access VPNs are used by remote users to securely connect to a LAN network over the internet. Site-to-site VPNs connect two LAN networks together, peer-to-peer VPNs connect two devices together, and remote-to-LAN VPNs are not a commonly recognized type of VPN connection.

Question 9

Most consumer access points are in reality wireless ____________________, because they combine the functions of an access point, router, network address translator, firewall, and switch.

Accepted Answer

The answer of Most consumer access points are in reality...

Question 10

Describe the Temporal Key Integrity Protocol used by Wi-Fi Protected Access (WPA).

Accepted Answer

The answer of Describe the Temporal Key Integrity Protocol used...

Question 11

____ authentication is used in the enterprise security model using WPA and WPA2.

Accepted Answer

IEEE 802.1x is the authentication protocol used in the enterprise security model for WPA and WPA2. AES and TKIP are encryption protocols used in conjunction with IEEE 802.1x for enhanced security.

Question 12

Describe Kerberos.

Accepted Answer

The answer of Describe Kerberos....

Question 13

Encryption under the WPA2 personal security model is accomplished by using the block cipher ____.

Accepted Answer

The block cipher used for encryption under the WPA2 personal security model is AES (Advanced Encryption Standard). TKIP (Temporal Key Integrity Protocol) is used for encryption under the WPA1 security model, and PSK (Pre-Shared Key) is a type of authentication method used in both WPA1 and WPA2. CBC (Cipher Block Chaining) is a mode of operation for a block cipher, rather than a specific block cipher itself.

Question 14

The ____________________ security model is designed for single users or small office home office (SOHO) settings of generally 10 or fewer wireless devices.

Accepted Answer

The answer of The ____________________ security model is designed for...
