Q61. John wishes to install a new application onto his Windows 2000 server. 

He wants to ensure that any application he uses has not been Trojaned. 

What can he do to help ensure this? 

A. Compare the file's MD5 signature with the one published on the distribution media 

B. Obtain the application via SSL 

C. Compare the file's virus signature with the one published on the distribution media 

D. Obtain the application from a CD-ROM disc 

Answer: A

Explanation: MD5 was developed by Professor Ronald L. Rivest of MIT. What it does, to quote the executive summary of rfc1321, is: 

[The MD5 algorithm] takes as input a message of arbitrary length and produces as output a 128-bit "fingerprint" or "message digest" of the input. It is conjectured that it is computationally infeasible to produce two messages having the same message digest, or to produce any message having a given prespecified target message digest. The MD5 algorithm is intended for digital signature applications, where a large file must be "compressed" in a secure manner before being encrypted with a private (secret) key under a public-key cryptosystem such as RSA. 

In essence, MD5 is a way to verify data integrity, and is much more reliable than checksum and many other commonly used methods. 

Q62. When Nmap performs a ping sweep, which of the following sets of requests does it send to the target device? 





Answer: B

Explanation: The default behavior of NMAP is to do both an ICMP ping sweep (the usual kind of ping) and a TCP port 80 ACK ping sweep. If an admin is logging these this will be fairly characteristic of NMAP.

Q66. Which of the following act in the united states specifically criminalizes the transmission of unsolicited commercial e-mail(SPAM) without an existing business relationship. 

A. 2004 CANSPAM Act 

B. 2003 SPAM Preventing Act 

C. 2005 US-SPAM 1030 Act 

D. 1990 Computer Misuse Act 

Answer: A

Explanation: The CAN-SPAM Act of 2003 (Controlling the Assault of Non-Solicited Pornography and Marketing Act) establishes requirements for those who send commercial email, spells out penalties for spammers and companies whose products are advertised in spam if they violate the law, and gives consumers the right to ask emailers to stop spamming them. The law, which became effective January 1, 2004, covers email whose primary purpose is advertising or promoting a commercial product or service, including content on a Web site. A "transactional or relationship message" – email that facilitates an agreed-upon transaction or updates a customer in an existing business relationship – may not contain false or misleading routing information, but otherwise is exempt from most provisions of the CAN-SPAM Act.

Q70. Which one of the following instigates a SYN flood attack? 

A. Generating excessive broadcast packets. 

B. Creating a high number of half-open connections. 

C. Inserting repetitive Internet Relay Chat (IRC) messages. 

D. A large number of Internet Control Message Protocol (ICMP) traces. 

Answer: B

Explanation: A SYN attack occurs when an attacker exploits the use of the buffer space during a Transmission Control Protocol (TCP) session initialization handshake. The attacker floods the target system's small "in-process" queue with connection requests, but it does not respond when a target system replies to those requests. This causes the target system to time out while waiting for the proper response, which makes the system crash or become unusable.
