NO.2 TCP SYN Flood attack uses the three-way handshake mechanism.
An attacker at system A sends a SYN packet to victim at system B.
System B sends a SYN/ACK packet to victim A.
As a normal three-way handshake mechanism system A should send an ACK packet to system B,
however, system A does not send an ACK packet to system B. In this case client B is waiting for an ACK
packet from client A.
This status of client B is called _________________
A. "half-closed"
B. "half open"
C. "full-open"
D. "xmas-open"
Answer: B

NO.3 More sophisticated IDSs look for common shellcode signatures. But even these systems can be
bypassed, by using polymorphic shellcode. This is a technique common among virus writers ?it basically
hides the true nature of the shellcode in different disguises.
How does a polymorphic shellcode work?
A. They encrypt the shellcode by XORing values over the shellcode, using loader code to decrypt the
shellcode, and then executing the decrypted shellcode
B. They convert the shellcode into Unicode, using loader to convert back to machine code then executing
them
C. They reverse the working instructions into opposite order by masking the IDS signatures
D. They compress shellcode into normal instructions, uncompress the shellcode using loader code and
then executing the shellcode

NO.14 Anonymizer sites access the Internet on your behalf, protecting your personal information from
disclosure. An anonymizer protects all of your computer's identifying information while it surfs for you,
enabling you to remain at least one step removed from the sites you visit.
You can visit Web sites without allowing anyone to gather information on sites visited by you. Services
that provide anonymity disable pop-up windows and cookies, and conceal visitor's IP address.
These services typically use a proxy server to process each HTTP request. When the user requests a
Web page by clicking a hyperlink or typing a URL into their browser, the service retrieves and displays the
information using its own server. The remote server (where the requested Web page resides) receives
information on the anonymous Web surfing service in place of your information.
In which situations would you want to use anonymizer? (Select 3 answers)
A. Increase your Web browsing bandwidth speed by using Anonymizer
B. To protect your privacy and Identity on the Internet
C. To bypass blocking applications that would prevent access to Web sites or parts of sites that you want
to visit.
D. Post negative entries in blogs without revealing your IP identity

NO.15 Lori is a Certified Ethical Hacker as well as a Certified Hacking Forensics Investigator working as an IT
security consultant. Lori has been hired on by Kiley Innovators, a large marketing firm that recently
underwent a string of thefts and corporate espionage incidents. Lori is told that a rival marketing company
came out with an exact duplicate product right before Kiley Innovators was about to release it. The
executive team believes that an employee is leaking information to the rival company. Lori questions all
employees, reviews server logs, and firewall logs; after which she finds nothing. Lori is then given
permission to search through the corporate email system. She searches by email being sent to and sent
from the rival marketing company.
She finds one employee that appears to be sending very large email to this other marketing company,
even though they should have no reason to be communicating with them. Lori tracks down the actual
emails sent and upon opening them, only finds picture files attached to them. These files seem perfectly
harmless, usually containing some kind of joke. Lori decides to use some special software to further
examine the pictures and finds that each one had hidden text that was stored in each picture.
What technique was used by the Kiley Innovators employee to send information to the rival marketing
company?
A. The Kiley Innovators employee used cryptography to hide the information in the emails sent
B. The method used by the employee to hide the information was logical watermarking
C. The employee used steganography to hide information in the picture attachments
D. By using the pictures to hide information, the employee utilized picture fuzzing

NO.16 You are the security administrator of Jaco Banking Systems located in Boston. You are setting up
e-banking website (http://www.ejacobank.com) authentication system. Instead of issuing banking
customer with a single password, you give them a printed list of 100 unique passwords. Each time the
customer needs to log into the e-banking system website, the customer enters the next password on the
list. If someone sees them type the password using shoulder surfing, MiTM or keyloggers, then no
damage is done because the password will not be accepted a second time. Once the list of 100
passwords is almost finished, the system automatically sends out a new password list by encrypted e-mail
to the customer.
You are confident that this security implementation will protect the customer from password abuse.
Two months later, a group of hackers called "HackJihad" found a way to access the one-time password
list issued to customers of Jaco Banking Systems. The hackers set up a fake website
(http://www.e-jacobank.com) and used phishing attacks to direct ignorant customers to it. The fake
website asked users for their e-banking username and password, and the next unused entry from their
one-time password sheet. The hackers collected 200 customer's username/passwords this way. They
transferred money from the customer's bank account to various offshore accounts.
Your decision of password policy implementation has cost the bank with USD 925,000 to hackers. You
immediately shut down the e-banking website while figuring out the next best security solution
What effective security solution will you recommend in this case?
A. Implement Biometrics based password authentication system. Record the customers face image to the
authentication database
B. Configure your firewall to block logon attempts of more than three wrong tries
C. Enable a complex password policy of 20 characters and ask the user to change the password
immediately after they logon and do not store password histories
D. Implement RSA SecureID based authentication system

NO.17 This IDS defeating technique works by splitting a datagram (or packet) into multiple fragments and the
IDS will not spot the true nature of the fully assembled datagram. The datagram is not reassembled until it
reaches its final destination. It would be a processor-intensive task for IDS to reassemble all fragments
itself, and on a busy system the packet will slip through the IDS onto the network. What is this technique
called?
A. IP Routing or Packet Dropping
B. IDS Spoofing or Session Assembly
C. IP Fragmentation or Session Splicing
D. IP Splicing or Packet Reassembly

anything. He pours through the Sniffer's manual, but cannot find anything that directly relates to
