Q71. Richard is a network Administrator working at a student loan company in lowa. This company processes over 20,000 students loan a year from colleges all over the state. Most communication between the company, schools and lenders is carried out through email. Because of privacy laws that are in the process of being implemented, Richard wants to get ahead of the game and become compliant before any sort of auditing occurs. Much of the email communication used at his company contains sensitive information such as social security numbers. For this reason, Richard wants to utilize email encryption agency-wide. The only problem for Richard is that his department only has couple of servers and they are utilized to their full capacity. Since a server-based PKI is not an option for him, he is looking for a low/no cost solution to encrypt email. 

What should Richard use? 



C. 3DES 


Answer: A

Explanation: PGP (Pretty Good Privacy) is an encryption program being used for secure transmission of files and e-mails. This adapts public-key encryption technology in which pairs of keys are used to maintain secure communication. For PGP-based communication both the sender and receiver should have public and private key pairs. The sender's public key should be distributed to the receiver. Similarly, the receiver's public key should be distributed to the sender. When sending a message or a file, the sender can sign using his private key. Also, the sender's private key is never distributed. All encryption is made on the workstation sending the e-mail. 

Q72. Bob is acknowledged as a hacker of repute and is popular among visitors of “underground” sites. Bob is willing to share his knowledge with those who are willing to learn, and many have expressed their interest in learning from him. However, this knowledge has a risk associated with it, as it can be used for malevolent attacks as well. 

In this context, what would be the most affective method to bridge the knowledge gap between the “black” hats or crackers and the “white” hats or computer security professionals? (Choose the test answer) 

A. Educate everyone with books, articles and training on risk analysis, vulnerabilities and safeguards. 

B. Hire more computer security monitoring personnel to monitor computer systems and networks.

Q77. You are scanning into the target network for the first time. You find very few conventional ports open. When you attempt to perform traditional service identification by connecting to the open ports, it yields either unreliable or no results. You are unsure of what protocols are being used. You need to discover as many different protocols as possible. Which kind of scan would you use to do this? 

A. Nmap with the –sO (Raw IP packets) switch 

B. Nessus scan with TCP based pings 

C. Nmap scan with the –sP (Ping scan) switch 

D. Netcat scan with the –u –e switches 

Answer: A

Explanation: Running Nmap with the –sO switch will do a IP Protocol Scan. The IP protocol scan is a bit different than the other nmap scans. The IP protocol scan is searching for additional IP protocols in use by the remote station, such as ICMP, TCP, and UDP. If a router is scanned, additional IP protocols such as EGP or IGP may be identified.
