Q354. RC4 is known to be a good stream generator. RC4 is used within the WEP standard on wireless LAN. WEP is known to be insecure even if we are using a stream cipher that is known to be secured.
What is the most likely cause behind this?
A. There are some flaws in the implementation.
B. There is no key management.
C. The IV range is too small.
D. All of the above.
E. None of the above.
Answer: D
Explanation: Because RC4 is a stream cipher, the same traffic key must never be used twice. The purpose of an IV, which is transmitted as plain text, is to prevent any repetition, but a 24-bit IV is not long enough to ensure this on a busy network. The way the IV was used also opened WEP to a related key attack. For a 24-bit IV, there is a 50% probability the same IV will repeat after 5000 packets. Many WEP systems require a key in hexadecimal format. Some users choose keys that spell words in the limited 0-9, A-F hex character set, for example C0DE C0DE C0DE C0DE. Such keys are often easily guessed.
Q355. William has received a Tetris game from someone in his computer programming class through email. William does not really know the person who sent the game very well, but decides to install the game anyway because he really likes Tetris.
After William installs the game, he plays it for a couple of hours. The next day, William plays the Tetris game again and notices that his machines have begun to slow down. He brings up his Task Manager and sees the following programs running (see Screenshot):
What has William just installed?
A. Remote Access Trojan (RAT)
B. Zombie Zapper (ZoZ)
C. Bot IRC Tunnel (BIT)
D. Root Digger (RD)
Answer: A
Explanation: RATs are malicious programs that run invisibly on host PCs and permit an intruder remote access and control. On a basic level, many RATs mimic the functionality of legitimate remote control programs such as Symantec's pcAnywhere but are designed specifically for stealth installation and operation. Intruders usually hide these Trojan horses in games and other small programs that unsuspecting users then execute on their PCs. Typically, exploited users either download and execute the malicious programs or are tricked into clicking rogue email attachments.
Q356. What command would you type to OS fingerprint a server using the command line?
A. Option A
B. Option B
C. Option C
D. Option D
Answer: C
Q357. Spears Technology, Inc is a software development company located in Los Angeles, California. They reported a breach in security, stating that its “security defenses has been breached and exploited for 2 weeks by hackers. “The hackers had accessed and downloaded 90,000 address containing customer credit cards and password. Spears Technology found this attack to be so to law enforcement officials to protect their intellectual property.
How did this attack occur? The intruder entered through an employees home machine, which was connected to Spears Technology, Inc’s corporate VPN network. The application called BEAST Trojan was used in the attack to open a “Back Door” allowing the hackers undetected access. The security breach was discovered when customers complained about the usage of their credit cards without their knowledge.
The hackers were traced back to Beijing China through e-mail address evidence. The credit card information was sent to that same e-mail address. The passwords allowed the hackers to access Spears Technology’s network from a remote location, posing as employees. The intent of the attacker was to steal the source code for their VOIP system and “hold it hostage” from Spears Technology, Inc exchange for ransom.
The hackers had intended on selling the stolen VOIP software source code to competitors.

A. Disable VPN access to all your employees from home machines
B. Allow VPN access but replace the standard authentication with biometric authentication
C. Replace the VPN access with dial-up modem access to the company’s network
D. Enable 25 character complex password policy for employees to access the VPN network.
Answer: A
Explanation: As long as there is a way in for employees through all security measures you can’t be secure because you never know what computer the employees use to access recourses at their workplace.
Q358. You are the IT Manager of a large legal firm in California. Your firm represents many important clients whose names always must remain anonymous to the public. Your boss, Mr. Smith is always concerned about client information being leaked or revealed to the pres or public. You have just finished a complete security overhaul of your information system including an updated IPS, new firewall, email encryption and employee security awareness training. Unfortunately, many of your firm’s clients do not trust technology to completely secure their information, so couriers routinely have to travel back and forth to and from the office with sensitive information.
Your boss has charged you with figuring out how to secure the information the couriers must transport. You propose that the data be transferred using burned CD’s or USB flash drives. You initially think of encrypting the files, but decide against that method for fear the encryption keys could eventually be broken.
What software application could you use to hide the data on the CD’s and USB flash drives?
A. Snow
B. File Snuff
C. File Sneaker
D. EFS
Answer: A
Explanation: The Snow software developed by Matthew Kwan will insert extra spaces at the end of each line. Three bits are encoded in each line by adding between 0 and 7 spaces that are ignored by most display programs including web browsers.
Q359. 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.
Q360. Angela is trying to access an education website that requires a username and password to login. When Angela clicks on the link to access the login page, she gets an error message stating that the page can’t be reached. She contacts the website’s support team and they report that no one else is having any issues with the site. After handing the issue over to her company’s IT department, it is found that the education website requires any computer accessing the site must be able to respond to a ping from the education’s server. Since Angela’s computer is behind a corporate firewall, her computer can’t ping the education website back.
What ca Angela’s IT department do to get access to the education website?
A. Change the IP on Angela’s Computer to an address outside the firewall
B. Change the settings on the firewall to allow all incoming traffic on port 80
C. Change the settings on the firewall all outbound traffic on port 80
D. Use a Internet browser other than the one that Angela is currently using
Answer: A
Explanation: Allowing traffic to and from port 80 will not help as this will be UDP or TCP traffic and ping uses ICMP. The browser used by the user will not make any difference. The only alternative here that would solve the problem is to move the computer to outside the firewall.
