Which of the following protocols provides an encryption by using the Temporal Key Integrity 

Protocol (TKIP)? 

A. EAP 

B. WEP 

C. IPSec 

D. WPA 

Answer: D 

Explanation: 

Wi-fi Protected Access (WPA) is an interoperable security protocol for Wireless LAN (WLAN). For using WPA, encryption is required. WPA provides encryption by using Temporal Key Integrity Protocol (TKIP). TKIP uses a new encryption algorithm, which is stronger than WEP algorithm. 802.1x authentication is required in WPA. Answer option B is incorrect. Wired Equivalent Privacy (WEP) is a security protocol for wireless local area networks (WLANs). It has two components, authentication and encryption. It provides security, which is equivalent to wired networks, for wireless networks. WEP encrypts data on a wireless network by using a fixed secret key. WEP incorporates a checksum in each frame to provide protection against the attacks that attempt to reveal the key stream. Answer option A is incorrect. Extensible Authentication Protocol (EAP) is an authentication protocol that provides support for a wide range of authentication methods, such as smart cards, certificates, one-time passwords, public keys, etc. It is an extension to Point-to-Point Protocol (PPP), which allows the application of arbitrary authentication mechanisms for the validation of a PPP connection. Answer option C is incorrect. Internet Protocol Security (IPSec) is a method of securing data. It secures traffic by using encryption and digital signing. It enhances the security of data as if an IPSec packet is captured, its contents cannot be read. IPSec also provides sender verification that ensures the certainty of the datagram's origin to the receiver.

Which of the following is a fake target that deters hackers from locating your real network? 

A. Honeypot 

B. KFSensor 

C. Malware 

D. Spyware 

Answer: A 

Explanation: 

A honeypot is a term in computer terminology used for a trap that is set to detect, deflect, or in some manner counteract attempts at unauthorized use of information systems. 

Generally it consists of a computer, data, or a network site that appears to be part of a network, but is actually isolated, and monitored, and which seems to contain information or a resource of value to attackers. Answer option B is incorrect. KFSensor is a Windows-based honeypot Intrusion Detection System (IDS). It acts as a honeypot to attract and log potential hackers by simulating vulnerable system services and Trojans. It has highly configurable features of detailed logging, analysis of attack, and security alerts. When using the KFSensor, a user can create different types of scenarios, such as what action should be taken when access to a honeypot is attempted. KFSensor contains many innovative and unique features, such as remote management, a Snort compatible signature engine, and emulations of real servers 

(e.g. FTP, POP3, HTTP, Telnet and SMTP) to deceive the hacker and gain more valuable information about his motives. Answer option C is incorrect. The term malware refers to malicious software, which is a broad class of malicious viruses, including spyware. Malware is designed to infiltrate or damage a computer without the consent of the owner. Answer option D is incorrect. Spyware is a program that takes partial control over a user's computer without user's permission. Spyware programs can collect various types of personal information, such as Internet surfing habits, and Web sites that the user has visited. Spyware programs can also interfere with the control of a user's computer, such as installing additional software, redirecting Web browser activities, accessing Web sites blindly, etc.
