Q12. You are footprinting an organization to gather competitive intelligence. You visit the company’s website for contact information and telephone numbers but do not find it listed there. You know that they had the entire staff directory listed on their website 12 months ago but not it is not there.
How would it be possible for you to retrieve information from the website that is outdated?
A. Visit google’s search engine and view the cached copy.
B. Visit Archive.org web site to retrieve the Internet archive of the company’s website.
C. Crawl the entire website and store them into your computer.
D. Visit the company’s partners and customers website for this information.
Answer: B
Explanation:
Explanation: Archive.org mirrors websites and categorizes them by date and month depending on the crawl time. Archive.org dates back to 1996, Google is incorrect because the cache is only as recent as the latest crawl, the cache is over-written on each subsequent crawl. Download the website is incorrect because that's the same as what you see online. Visiting customer partners websites is just bogus. The answer is then Firmly, C, archive.org
Q13. Bob waits near a secured door, holding a box. He waits until an employee walks up to the secured door and uses the special card in order to access the restricted area of the target company. Just as the employee opens the door, Bob walks up to the employee (still holding the box) and asks the employee to hold the door open so that he can enter. What is the best way to undermine the social engineering activity of tailgating?
A. issue special cards to access secured doors at the company and provide a one-time only brief description of use of the special card
B. to post a sign that states “no tailgating” next to the special card reader adjacent to the secured door
C. setup a mock video camera next to the special card reader adjacent to the secured door
D. to educate all of the employees of the company on best security practices on a recurring basis
Answer: D
Explanation: Tailgating will not work in small company’s where everyone knows everyone, and neither will it work in very large companies where everyone is required to swipe a card to pass, but it’s a very simple and effective social engineering attack against mid-sized companies where it’s common for one employee not to know everyone. There is two ways of stop this attack either by buying expensive perimeter defense in form of gates that only let on employee pass at every swipe of a card or by educating every employee on a recurring basis.

Q15. You have successfully run a buffer overflow attack against a default IIS installation running on a Windows 2000 Server. The server allows you to spawn a shell.

Which of the following options would be your current privileges?
A. Administrator
B. IUSR_COMPUTERNAME
C. LOCAL_SYSTEM
D. Whatever account IIS was installed with
Answer: C

Q16. Derek has stumbled upon a wireless network and wants to assess its security. However, he does not find enough traffic for a good capture. He intends to use AirSnort on the captured traffic to crack the WEP key and does not know the IP address range or the AP. How can he generate traffic on the network so that he can capture enough packets to crack the WEP key?
A. Use any ARP requests found in the capture
B. Derek can use a session replay on the packets captured
C. Derek can use KisMAC as it needs two USB devices to generate traffic
D. Use Ettercap to discover the gateway and ICMP ping flood tool to generate traffic
Answer: D
Explanation: By forcing the network to answer to a lot of ICMP messages you can gather enough packets to crack the WEP key.
Q17. A Company security System Administrator is reviewing the network system log files. He notes the following:
-Network log files are at 5 MB at 12:00 noon.
-At 14:00 hours, the log files at 3 MB.
What should he assume has happened and what should he do about the situation?
A. He should contact the attacker’s ISP as soon as possible and have the connection disconnected.
B. He should log the event as suspicious activity, continue to investigate, and take further steps according to site security policy.
C. He should log the file size, and archive the information, because the router crashed.
D. He should run a file system check, because the Syslog server has a self correcting file system problem.
E. He should disconnect from the Internet discontinue any further unauthorized use, because an attack has taken place.
Answer: B
Explanation: You should never assume a host has been compromised without verification. Typically, disconnecting a server is an extreme measure and should only be done when it is confirmed there is a compromise or the server contains such sensitive data that the loss of service outweighs the risk. Never assume that any administrator or automatic process is making changes to a system. Always investigate the root cause of the change on the system and follow your organizations security policy.
Q18. Network Intrusion Detection systems can monitor traffic in real time on networks.
Which one of the following techniques can be very effective at avoiding proper detection?
A. Fragmentation of packets.
B. Use of only TCP based protocols.
C. Use of only UDP based protocols.
D. Use of fragmented ICMP traffic only.
Answer: A
Explanation: If the default fragmentation reassembly timeout is set to higher on the client than on the IDS then the it is possible to send an attack in fragments that will never be reassembled in the IDS but they will be reassembled and read on the client computer acting victim.
Q19. After an attacker has successfully compromised a remote computer, what would be one of the last steps that would be taken to ensure that the compromise is not traced back to the source of the problem?
A. Install pactehs
B. Setup a backdoor
C. Cover your tracks
D. Install a zombie for DDOS
Answer: C
Explanation: As a hacker you don’t want to leave any traces that could lead back to you.
